The frame similarly of channel iron is rectangular and open at the rear end, the latter braced at its upper edge by a cross bar which in turn supports a gear drive housing FIG. The lower flange element of the channel iron slidably supports a rectangular frame memberpreferably of angle iron, the open angle directed upward and inward.

Two parallel sides of frame member each has a rack gear fixed thereon for cooperation with a driving spur gear mounted for drive on counter shaft The sliding frame has the upper edge of the box firmly fastened thereto by several fastening ear members disposed at the front and rear edges. The lower frame member is further braced by a forward intermediate cross bar which has downturned ends which firmly engage the top of the channel and support the bar upward in about the plane of the frame The downturned ends of brace FIGS.

Fixed to pivot shaft for rotation therewith are a pair of arcurate pivot arms The lower end of pivot arm pivotally supports a pivotally swinging drive which carries both spur gears aligned thereon for meshing with vertical rack gearsand also carries spur gears aligned for meshing with horizonal rack gears By pivotal movement of pivot arms and pivot shaft to an upper position, spur gears will mesh with vertical rack gears for raising and lowering of the lower frame and box mounted thereon vertically; lazy tong arms and fol-ding and unfolding to accommodate the raising and lowering of the lower frame When pivot arms are at the lower pivotal position, the spur gears will mesh with horizontal racks for horizontal drive thereof.

A small electric driving motor is firmly mounted to support frame element to drive through a series of reduction gears through a final output gear to supply slow rotary output, which connects through shaftthence through a similarly rotatable couplerthrough shaftterminating in a beveled pinion gear which engages a ring gear fixed to rotatably drive the pivot shaft The pivot shaft suspended on pivots has spur gears at an extreme end fixed to shaft and inner spur gears fixed at inner positions on shaft as shown in FIGS.

A sprocket gear is mounted axially slidable but splined to pivot shaft as controlled and will rotate with the shaft when a clutch means is engaged as shown in FIG. A clutch throw-out collar wheel is also rotatably mounted and fixed to the spur gear for movement axially by a forked end clutch throw-out arm operated from a rufus j weaver biography control lever FIGS.

The clutch throw-out lever is held within a slot of a pivot shaft cage FIG. The cagehowever, is supported pivotally by a link arm FIG. In the downward position the spur gears will engage the racks and move the same either to the rear or on reverse rotation, forward, depending upon the direction of rotation of the motor When the control level is moved in the revers direction, the pivot shaft is raised upward on pivot armsin which position spur gears will engage the vertical rack gears and will cause the frame member to move up or down on its lazy tong pivoted arms as shown in FIG.

Thus, by manual operation of control lever the box 75 is lowered or moved to the rear or forward to assembled position as shown in FIGS. A sprocket chain may be entrained around both gear and a forward sprocket gearthe latter being rotatably fixed to rotate with a chair tilt drive shaft which extends at opposite ends through the frame member 47 and is rotatably supported therein with each and engaging pivot shaft 62 for imparting a tilting pivotal movement to the chair frame By lateral movement of the hand lever engaging the clutchrotary power is imparted to shaft through the sprocket chain and gearing to impart tilting movement to the chair The sprocket chain may be loose enough to accommodate lateral movement of gear on shaft for purposes of disengaging the clutch A lock assemblyshown in detail in FIG.

For this purpose a lateral translational shaft is mounted to lie upon and move parallel to support beam The inner end is provided with a shoulder and is positioned to be intercepted by operating level in lateral movement, whereby the shaft is moved longitudinally therewith along beam The shanking of the shaft is slotted at to receive a retaining pin mounted in sliding fit in slotslidingly retaining the shaft in longitudinal movement.

The end of the shaft is bored to receive a downturned arm of a rotary toggle mounted to rotate about pivot pinthe opposite arm of the toggle being fixed in a boreimparting corresponding longitudinal motion to a second actuating shaft The shaft is similarly mounted to slide upon the cross brace and is similarly slidingly pinned thereto by a pin within a sliding rufus j weaver biographythereby allowing sliding longitudinal movement parallel to and displaced the radial distance of said toggle from the shaft A spring biases the toggle and shafts into actuating engagement with the control shaft in its normal central inoperative position.

A chair tilting locking pin comprising a bent angle shaft is integrally secured to the end shaft and is simultaneously moved laterally opposite as the control lever is actuated laterally. The dimensions of the several levers and support of the locking rod is such that the rod will lie directly in back of the corner end of the chair in tilt position as shown in FIGS.

Thus, the end of rod will lie behind the corner and will lock the chair in the tilt position when the control lever is in neutral vertical position and will be withdrawn from that locking position when the lever is depressed laterally. When the chair is in normal ambulatory horizontal position, another locking device is operative to main tain the chair locked to the horizontal position and the spring will bias the locking rod end to merely slide against the side frame 13 without locking effect thereon.

In reverse direction of rotation, motor and shaftlowering tilt arms 62, the chair is returned to normal horizontal position. By holding the shaft relatively vertical, the clutch is maintained normally disen gaged.

The shaft FIGS. A latching bar having a latching lip is slidably mounted in a locking cagewhich in turn is securely fastened to the forward end of frame A compression spring is secured about the locking bar to bias the latch lip outwardly, engaging the upper surface of the forward frame element 13 to latch it. A pair of lateral pins extend laterally from each side of and are fastened to the latching bolt to be engaged one each by the curved surface of a spring-like disengaging armeach arm being fixed for rotation in a pivot As thus described, the continued rotation of shaft in chair-tilting direction, simultaneously rotating cam forces the latch engaging arms downward and thereby the inner curved body of arms engage pins which force the latching bar to move in reverse direction against pressure of springas the arms turn downward with camreleasing the latching bar lip from engagement with the forward frame surface 13, thereby freeing the chair seat for pivotal upward tilting rotation from frame member Upon reversal of drive of shaft and return to normal horizontal seated position of the chair, the latching member on frame 47 will reengage the forward frame portion of the chair 13 and lock it in horizontal position.

Upon movement of the control lever to the rear, the spur gears will engage the vertical racks and rotation of shaft through clutch will raise or lower the box A braking means is provided to fix the vertical position of the box 76, which comprises a set of vertically disposed serrated teeth each mounted on a horizontal sliding bar and coupled together by a spring shaft lying upon and slidingly held thereon by sleeves at each end upon cross brace A retaining bracket extends outward from the cross shaft having a turned up collar to receive the center portion of the flat end of a spring member having bent ends lying against the rufus j weaver biography of bar biasing bot- h sliding bars and teeth against vertical rack gearsthereby locking the carriage frame and box in fixed position upon the vertical gears.

The sliding shafts each have a hole in an outer end FIG. The opposite end of the cable is fixed to the lower ends of each corresponding pivot arm FIG. When the control arm is moved to the rear, thus causing the spur gears to engage the vertical racks The upward pivotal movement of arms draw upon the lower end of the cableas the pivot shaft is moved upward therewith and, thus, simultaneously disengages the serrated teeth braking hold upon the racks Thus, as described, the vertical movement of carriage frame and box 75 available through rack gears is continually stopped by the breaking contact of teeth in bars biased by spring against the racksexcept when positive vertical drive is applied by spur gears against the racks for raising or lowering the box 75 and its carriage frame Upon termination of the vertical drive effect, the brake immediately is applied by the spring bias of spring upon bar Thus, it will be noted that the reversible driving motor imparts power for drive through pinion and ring gear for operation of the several motions controlled by lever In clutch position, other than vertical, it controls the tilt and horizontal positioning of the chair by lateral movement.

In forward positioning of the leverit controls the drive of the horizontal gears to move the climbing box to the rear for engagement of the steps, or reassembles the climbing box for ambulatory motion of the box upon its wheels directly beneath the chair. Upon movement of control lever to the rear, the pivotal shaft is moved upward for engagement of the vertical drive with racks as described.

The ring gear has long teeth to accommodate pivotal movement of shaft so that the pinion may slide inward and outward against the teeth of gear without losing meshing contact therewith.

Stair climbing safeguards It is desirable for a stair-climbing chair, where the wheels are deliberately lifted from support position during climbing, the device resting on the chair climbing box, on the staircase, and upon approaching the top of a staircase for descent, to provide maximum safety whereby the chair itself will sense the presence of the floor ready for movement upon its wheels; and will lock automatically where the support of the floor has terminated; for instance, at the top of a staircase ready for descent.

For this purpose, and referring to FIGS. Locking sprocket wheels are mounted to the inner sides on shafts to rotate with the hubs Each of the sprocket wheels have teeth curved on a vertical edgein the direction of reverse rotation of wheels 16, and a straight side on edge to cooperate with a locking bar The locking bar as shown in FIGS. The forward end of the frame terminates at the center of the sprocket to form an abutment against a vertical sprocket tooth surface in its vertical 12 oclock position, preventing, as an abutment, any further rotation of the sprocket wheel in the forward rotational direction, so that each wheel 16 becomes locked against forward rotation when the locking bar and frame are lowered to engage the vertical surface of a tooth In the reverse direction, the wheel is free to rotate so that the locking effect is only against forward rotational motion only.

The locking bar supports a vertical sleeve at its forward end which slidingly receives a vertical reciprocable locking rod which at its rufus j weaver biography end senses the level of the floor. When the floor is not present to intercept and support the vertical position of the rod holding the bar and frame in its upper position, to stop its further descent, the locking bar attached to rod will have descended to locking position upon the locking wheel- Inin the year that Rufus J Weaver was born, the first "talkie" a movie with music, songs, and talkingThe Jazz Singer, was released.
