TYPE-WRITING MACHINE.

Specification of Letters Patent.

Patented May 5, 1908.

Application filed November 7, 1904-. Serial No. 231,749.

To all whom it may concern:

Be it known that I, FRANK A. YOUNG, citizen of the United States, and resident of Syracuse, in the county of Onondaga and State of New York, have invented certain new and useful Improvements in Type-Writing Machines, of which the following is a specification.

This invention relates to .typewriting machines and has for its main object to-provide an improved construction of type rest, pad or cushion. p

T 0 this and other ends which will subsequently appear, my invention consists in the .features of construction and combinations of devices to be hereinafter more fully set forth and particularly pointed out in the concludin claims.

in the accompanying. drawings forming part of this specification, Figure 1 is a front to rear sectional view of atypewriting machine embodying my invention, parts of" the m'achine'being omitted. Fig. 2 is a view taken on the line x:r of Fig. 1, showing the type rest and its su ports, and the ends of several ty e bars. ig. 3 is an end view of ig. 4 is a fragmentary sectional V18W showing the connection between the type rest and one of its supporting brackets. Fig. 5 is a top plan view of the facing or pad of the type rest. Figs. 6 and 7 are detail, views of the retaining member of the facing orpad. Fig. Sis a view of a modified form of retaining or securing means for the facing.

This invention 15 illustrated'hereln as applied to the Monarch typewritin machine, but I desire it to be understood t at it may be applied in whole or in part to other forms of writing machines.

In the drawings, 1 indicates the base of the machine sustaining corner posts 2 which support a top plate 3 upon which is mounted a carriage (not shown) can'yin%a platen 4 dia grammatically illustrated. levers 5 are notched to cooperate with a guide rod 6 and each key lever has a curved face or edge 5 thatcooperates with a fulcrum plate 6 in the rear of the base of the machine, each of' said key levers being also provided with a keybutton 7 and a restoring spring 8. Pivoted at 9 to each key lever is. a sub-lever 10,

' the'lower portion of which is formed with a slot 11 embracing a fixed fulcrum bar 12 which passes from side to side of the machine beneath the-bank of key levers and is securedof the machine.

of each sub-lever is pivotally connected at 13 in the side walls of the base. The upperend to the rear-end of a connecting link 14, the

forward end whereof is pivoted at 15 to a type" bar 16. Each type bar 16 is seated in one off a series of radial slots 17 formed in a 'seg-- mental support 18 and is mounted upon a ivot rod 19 which is seated in a groove cut 1n the top of the segmental support. type bar is provided with a rest'orin spring 20 and carries at its free end a type b ock 21. Q.

The series of bars at their free or forward ends are supported in normal position by a type rest 22. v

The type rest as illustrated in the accompanying-drawings, comprises an inner support, rod or'core piece 23, a helix or coiled s ring 24 having a larger internal diameter t an the exterior diameter of the rod and surrounding said rod or su port and a facing or pad 25 mounted u on tlie helix and interposed between it an the type bars so that the latter normally rest upon the pad. The support 23 is a segmental rod preferably hollow but having its ends solid, which result is obtained by securing plugs 26 therein. Abutting each end of the support 23 is a curved member or bracket 27 to which the sup ort is fixedly secured by a headed screw 28 w 'ch passes through a perforation in the end of the bracket 27 and is screwed into a tapped hole in the top of the plug 26. The lower ends of the bracket members27 partly embrace or surround the shanks of headed screws 29 which are readily accessible from the front The screws 29 are screwed. into the forward ends of horizontally disposed rods 30 which latter are secured to the type bar'segment 18 "and project forwardly from it at either side. The edges of that portion of each bracket 27 embracing the shank of the screw 29 are held in contact with the front face of the rod 30 and the under side of the head of said screw. The construction is such thatthe support 23 and the parts mounted thereon may be readily removed fromthe machine by unscrewing the headed securing screws 29, while, when the rest is in place in the machine the supporting member 23 is securely held in a fixed position rela.-- tively to the type bar segment. 'The helix:

24 is preferably formed of spring wire and is I threaded upon the support 23 before it is seecured to the brackets 27, which latter serve .to confine the resilient wire helix toits sup port. The helical wire spring 24 when mounted upon the rod 23 conforms to the curve of the latter, the coils tending to press upward against the under side of tne rod 23 except near the ends of the helix where they tend to press downupon the top portion of the rod in the effort of the helix to straighten itself longitudinally. To overcome this tendency of the ends of the helix, means are .em-

g the ployed consisting of short coiled springs 31 mounted upon headed screws 32, the latter enterin the under side of the rod 23 near its ends. ach coiled spring 31 presses upward.

. made of'some non-resilient. pliant material .on the dotted lines at the ends such as leather and, as herein shown, coniprises two layers 33. and 34 between which is secured means for connecting the facing to the helix. The preferred form of connecting means is shown In detail in Figs. 6 and7 as a member 35 consisting of a series of fingers 36 joined by a central web 37. This member 35 may be conveniently formed of an exceedingly thin strip of metal punched or cut to the shape shown. It is interposed between the-layers of leather or some such suitable material which are thereafter suitably secured together as by rows of stitching 38, the under layer having previously been notched or cut away at 39 beneath the fingers 36 so that the latter ma be bent down to loosely embrace or partia y surround the helix 24, thereby connecting the facing with the helix so that both are free to move independently of each other. i

The securing fingers may if .desired be independently formed and separately connected with the facing as by inserting them between the layers of the latter. One of such fin ers 40 is shown in Fig. 8 as having a cen tra portion 41 somewhat broader than the ends 42, which latter are designed to be bent of the central portion 41. The type bar returningfrom the printing oint after being actuated to println a welliinown manner, strikes the non-resilient facing, slightly depressin or indenting it at the point of contact and t ereby drawing the portions at either side towards the indenta tion, causin -the facing to slide or move slightly longitudinally of the helix. Where the securing means employed is that illustrated in Figs. 6 and7, the web 37 must be suiiiciently thin and pliable to allow this result to bagbtained. The coils of the helix ssas'm are also slightly depressed by the type bar at" the oint ofim act and the force of the blow is ta en up or istributed both by the leather and the helix, the tension of the coils of the latter gradually increasing as they are both basket of adjacent type bars when they are.

rapidly operated. It will be noted that I have rovided a ty e' rest comprising a curved pliant, flexib e, elastic member or helix, that the elastic member is faced with a tough pliant material in the form of-a leather pad; and that the flexible yielding member or helix is sup orted by a rigid, fixed mem-v ber or core r0 which constitutes a backing therefor. I

Various changes may be effected in the construction, combination and arrangement depressed towardsthe inner supporting bar this j of '(parts of my invention as herein set forth 5 an parts of the device may be used without other parts, all within the scope of my invention. 1 What I claim as new and desire to secure by Letters Patent, is 2-- 1.
