SLIDING SUPPORT FOR TYPEIVRITERS.

Specification of Letters Patent. P t t d 22 19220 Application filed August 22, 1919. Serial No. 319,082.

T 0 all whom it may concern:

Be it known that 1, JOHN ARTHUR No'r'r, a subject of the King of Great Britain and Ireland, residing at Chicago, county of Cook, State of Illinois, have invented a certain new and useful improvement in Sliding Supports for Typewriters, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention has for its object duce a simple and novel cushioning support for a typewriter which will permit it to be accurately aligned upon a typewriter desk and slide back into an idle position when the supporting table is tilted for the pur-- pose of closing the desk.

A further object of the present invention is to produce a simple and novel hook or stop device adapted to be mounted upon a typewriter for co-operation with a sliding support which, by the substitution of one simple part for another, can be applied to any one of a great variety'of types of typewriters.

The various features of novelty whereby my invention is characterized will hereinafter he pointed out with particularity in the claims; but, for a full understanding of my invention and of it objectsand advantages, reference may be had to the following detailed description taken in connection with the accompanying drawing, wherein:

Figure 1 is a side elevation of the lower portion of a typewriter frame equipped and supported in accordance with the present invention,-the supporting table being shown to proare preferably stamped out of metal but may be otherwise formed; these members being adapted to be secured upon the table of a typewriter desk so as to lie parallel witheach other and at right angles to the front edge of the table; the distance between the longitudinal centers of the troughs or channels being the same as the distance between the centers of the supportmg feet or opposite sides of the typewriter to supported. Within each trough is an elongated sliding cushion considerably shorter than the trough but long enough to span the two supporting feet on one side of the typewriter. In the arrangement shown, each cushion is made up of an under layer, 3, of felt and an upper layer, 4:, of rubber, cemented or otherwise secured together. Underlying each cushion and extending upwardly between one or both sides thereof and the sides of the corresponding trough or channel, is a layer, 5, of felt or other-suitable material which will prevent the cushion from sticking to the sides of the channel or trough. The parts are so proportioned that the cushion with its partial envelope, 5, has a sliding fit in its trough or channel so that there will be no lateral play between the ,cushion and the trough or channel while, at the same time, the cushion may be moved freely in the lengthwise direction. The top of the cushion preferably lies somewhat below the upper edges of the sides of the trough or channel, while the side members of the envelope or sheathing, 5, preferably extend slightly above the trough or channel.

If the feet of the typewriter do not happen to be of the proper size I substitute therefor feet, 6, preferably of rubber, flat on thebottom and of a diameter substantially the same as the width of the cushion. Therefore, after the two troughs or channels have been properly fastened upon the table, indicated at 8, and the cushions placed therein, the typewriter, of which a part of the frame 7 is illustrated, may be mounted with its four feet resting on the two cushions; the feet extending somewhat downwardly into the troughs so that the upper portions of the sides of the latter prevent lateral displacement of the typewriter; and the uppermost portions of the sides of the sheathing, 5, being interposed between the side Walls of the troughs or channels and writer to' move toward the back or toward the front.

The movement of the typewriter in one direction, namely toward the rear in the example illustrated, is through the action of gravity when thetable of the desk is tilted during.theprocess of closing the desk and" therefore it is necessary that some kind of a stop be provided to limit the automatic shiftinggofthe typewriter. There are preferably two of such stop devices, one on each side of the. typewriter and each necessarily comprises. a stationary part and apart movable witlr the typewriter. The stationary member of my improved stop preferably. consists of a block, 9, having thereon: a. forwardly and upwardly-projecting finger, 10. Each block is adapted to lie beside one of the guiding and supporting channels or troughs and ispreferably interlocked with the latter so as to permit the block to beheld firmly in place by means of a single screw. In the arrangement shown, each block has a.laterally-projecting tongue, 11, adapted to extendinto a longitudinal groove, 12, ofthe corresponding channel'or trough; .Thegroove, 12, is preferably made longer than the block so as to permit the latter to be adjusted relatively to the trough or channel in the longitudinal direction. This permits the supporting and guiding elements to be attached to the table and the stationary stops tobe adjusted thereafter without 'making it necessary to shift thewriter consists of an. inclined fin or ear,

14, adapted to project later-ally into the plane ofthe-inclined finger and to pass underneath the latter as the typewriter. slides back, so that. the finger exerts a wedging action-on the traveling-stop member, tending to force it downwardlyand thus holdingv the typewriter firmly to. itssupport after it has traveled back as far as it can go. The I stop member 14'n1ust be attached. to some part of the frame of the typewriter and, since typewriters of different makes have differently shaped frames, it is necessary that a variety'of attaching means are re quired,

"he part 14 should remain the same, regardless of' the make of the type- I writer and therefore, in order to simplify and cheapen the manufacture, I make the traveling stop member in two parts, one of which is universal in its applicationwhile the other. may. be replaced by a substitute part according to the style of typewriter which is being fitted. In the arrangement shown, the element 14 is arranged onthe lower'end of a vertical-plate, 15, having at the top an outwardly and laterally-directed.

flange, 16, inclined from front to rear; in the opposite direction from the inclination of the-element 14. The other half of the device consists of a plate,.17, having a flange, 18,;

a portion of the element 19. At the lower endof the part 20 is a hook, 21, adapted to engage with the under edge of the side bar of the typewriter frame. On the upper end of the member 20. is a nut, 22. .Itwill be seen that when the parts are assembledv as The two parts of the shown inFigs. 1 and 2, the nut, 22, being screwed. down, the stop device is firmly clamped upon the I typewriter.

Where the frame of the typewriter is different from that herein illustrated, a differently shaped piece is substituted for the part 17 with itshook 19. Thus,'as shown in Figs. 4 and 5,.the member that co-opcrates with the part of the stop carrying the car 14 may consist of a plate, 24,.lying against the inner side of the plate 15- andhaving an outwardly direotedfiange, 25,

whichoverlies the flange 16 there being at the lower end of the plate 24 aninwardlydirected flange, 25. This modified form of stop is fastened to the typewriter by means of a bolt, 26, passing through alignedholes in the plates 15 and 24. -Only a single bolt is required because the engaging flanges-16 and 25serve to lock the two halvesof. the

stop together after the bolt is in place. I

While I haveillustrated and described with particularity only a single preferred formof my invention, I'do not desire to'be. limited to the exact structuraldetails thus illustrated and described; but intend to cover all forms and. arrangements which. come within the terms employed inthe definitions of my invention constituting the appended, claims.
