TYPE-WRITING MACHINE.

Specification of Letters Patent.

Continuation of application Serial No. 226,935, filed January 5, 1903. This application filed June 30,1905. Serial No. 267,805-

To (ti/Z whom it may concern:

Be it known that I, JACOB FELBEL, a citizen of the United States, and a resident of the borough of Manhattan, city of New York, in the county of New York and State of New York, have invented certain new and useful improvements in Type-WVriting Machines, of which the following is a specification.

My invention relates to type-writing machines, and more particularly to type-bar baskets or rests therefor.

The object of my invention is to provide a simple construction of type-bar basket or rest which is capable of greatly reducing the rebound of the type-bars when they strike the basket in their movements back to normal positions, and thereby avoiding the lia- -b1lity of adjacent type-bars conflicting or colliding near the type-bar basket during the rapid operation of the machine.

To the above and other ends, which will hereinafter appear, my invention consists in the features of construction and combinations and arrangements of parts hereinafter described, and particularly pointed out in the appended claims.

In the accompanying drawings, wherein like reference characters indicate corresponding parts in the various views, Figure 1 is a vertical front-to-rear sectional view of one form of type-writing machine embodying Fig. 2 is a vertical longitudinal sectional view of the basket, the view being taken on the line at :c of Fig. 1 and looking in the direction of the arrow in said figure. Fig. 3 is an enlarged detail fragmentary perspective view of the pad shown. in Figs. 1 and 2. Figs. 4 and 6 are like views showing other forms of pads embodying my invention. Fig. 5 shows in perspective other forms of pins which may be employed. Fig. 7 is a plan view of a pad shown in Fig. 6, and Fig. 8 is an enlarged detail fragmentary perspective view of still another form of pad wherein both felt and leather may be employed in the construction thereof.

The frame 1 of the machine is surmounted by a top plate 2, which supports a suitable carriage (not shown) that is provided with a platen 3, (Diagrammatically illustrated in Fig. 1.

The key-levers 1 are pivoted on a rod 5 and have the usual finger-keys 6 and restoringsprings 7. Pivotally connected to the key lever at S is a sublever 9, the lower portion of which is slotted at 9 for cooperation with the fixed fulcrum-rod 10, that extends from side to side of the machine. To the upper end'of each sublever is pivoted at 1 1 a link 12, which is pivoted at its forward end 13 to a type-bar 14. To each type-bar is pivoted at 15 a link 16, to which one end of a spring 17 is'connected, the other end of said spring being connected to a hook 18, secured to the type-bar basket, designated as a whole by 19. The various type-bars are pivoted on a segmental pivot-wire 20, that is carried by the type-bar segment 21, and the type-bars are adapted to strike upwardly and rearwardly.

The type-bar basket 19 1s rigidly supported by rods 22, that extend forwardly from' the type-bar segment. Said basket comprises a rigid segmental metallic case or support 23, that is trough-like or U-shaped in cross-section, and this device supports a pad 24 throughout or substantially throughout the length thereof. This pad maybe made of one piece of felt or other like soft or yielding material or of two pieces of different materials. Extending transversely of the pad and seated or embedded therein edgewise of the pad and at intervals throughout its length are horizontally disposed parallel pins 25 which are preferably of a non-resilient material, such as copper or lead. In Figs. 1, 2, and 3 these pins are indicated as separate pieces and are entirely surrounded by the pad, excepting at their ends. From an examination of Fig. 1 it will be observed that the sides of the trough-like support extendvup and over the ends of the pins, so as to prevent a longi tudinal displacement thereof from the pad.

The pins instead of being separate pieces, as indicated in Figs. 1, 2, and 3, may be connected or made in the form of staples 25*, as in Figs. 4 and 8, or the pins may be connected one to another throughout the series thereof, as indicated in Figs. 6 and 7, wherein a comb-like piece of copper or other suitable hard or inflexible material is seated or embedded in the pad. The various pins, fingers, or projections 25 extend laterally from a connecting-bar 25, so as to form a comb like structure. The pins may extend in substantially the same relation to the pad as the separate pins 25 shown in Figs. 1, 2, and 3. The construction shown in Figs. 6 and 7 from certain aspects may be regarded as a the-impact of the type-bars.

- pad.

pad having a longitudinally-extending metallic strip seated or embedded therein, the

-metallic strip having openings or spaces at stitching b, with the transverse pins or metallic pieces interposed between them.

In the employment of a pad such as just described I prefer to use the felt strip to receive In any detail construction a felt pad or facing reduces noise to the minimum; but unfortunately it causesan excessive rebound of the type-bars unless some means are specially provided for reducing the same. This I have provided, and my pads yield the minimum of sound and rebound.

It willbe observed that the pins or pieces extend in the general directions of the type bar's when the latter are at rest on the pad which normally supports the free ends thereof; that the pins or pieces are fixed within the pad; that certain of them have intermediate connections; that the pins or pieces ex-; tend substantially under and crosswise of the ,upper or contact face of the pad and substantially parallel to said face and that they are arranged transversely of the pad that the comb-like piece shown in Figs. 6 and 7 .extendsthroughout or substantially throughout the length of the pad and has a portion 4 that .extends longitudinally ofthe pad and integral projections, pins,'or fingers that project therefrom transversely of the pad; that the metal pins shown in Fig. 8 are interposed between a plurality of strips of material that extends longitudinally of the pad, and that in the various constructions shown the comb .or pins are embedded in the pad within the field-of impact of the type-bars against the The pins or metallic pieces may be inserted while the pad portions are straight, and

thereafter the pads may then be given a curvature corresponding to the segmental support'23 provided therefor.

If'desired, each pad may be made of several segmental sections butting end to end, though I prefer'to make each pad continuous, as shown.

Although I prefer to' make the rebound- ,i f ducing pins, fingers, or teeth of metal, nevertheless some other equivalent material may *be employed instead in so far as the broader they have practically no resiliency and 0 erate to reduce the rebound of the typears to an extent such that there is no clashing of adjacent type-bars in the vicinity of the pad when the type-bars are operated rapidly. By using a felt or soft material for the face of the pad there is little or no sound resulting from the impact of the type-bars on their return movements to rest. Hence the desideratum is obtained of a practically noiseless'pad with the rebound reduced to a minimum.

What I claim as new, and desire to secure by Letters Patent, is
