' Specification of Letters Patent.

Application filed September .20, 1919. Serial No. 325,115.

' To all whom it My concern:

new and useful Improvements in .Typewriter Pads, of which the following is a specification.

This invention relates to typewriter pads. The object of the invention is to provide a pad constructed to eliminate the use of ribbons and-which is so constructed as to properly retain the ink thereb greatly prolonging the life thereof ren ering it both practical and economical. Another object is to provide a pad of this character which may be readily slipped on or off the ribbon vibrator, as for'lnstance in the Remington typewriter machines.

Another object is to so construct a pad of this character that the type will be pre- -vented from clogging thereby avoiding 'the nialcessity of cleaning them except occaslona ya With the foregoing and other objects in -view, which will appear as-the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter de scribed and claimed it being understood that changes in the precise embodiment of the inventlon herein disclosed may be made within the scope of what is claimed without departing from the s irit of the invention.

In the accompanying drawings Figure 1 represents a front elevation of a typewriter pad constructed in. accordance with this invention and shown applied, the support therefor being shown broken ofi,

Fig. 2 is a top plan view thereof,

Fig. 3 is a transverse section taken on the line 3-3 of Fig. 1,

Fig. 4 is a frontelevation of the pad detached, and e Fig. 5 is a detail longitudinal section on an enlarged scale taken on the line 5-5 of Fig. 4:.

In the embodiment illustrated, the pad 1 constituting this invention is equipped with tubular supports 2 at its opposite ends which are split longitudinally and provided along the walls of said slip with outwardly projecting li which are preferably corrugated to c ampingly engage the ends of the pad which is secured thereto by rivets or other'fastening elements 3 as'is shown clearly in Fig. 4:, the ends of the pad being extended into the tubes 2 as is shown clearly in Fig. 5.

separate layers 5 and 6, one of which is constructed of-fine grade canton flannel having The pad numbered 4 is composed of two a firm nap and a fine smooth back and which is here numbered 6. The other layer 5 is composed of the same quality silk as'that which s used in making typewriter ribbons but 1t is inked somewhat heavien. The edges of the two strips 5 and 6 are selvedged. The ends of the strips 5 and Gafter entering the tubes 2 diverge as shown in Fig. 5 and are" secured by the rivets 3 as above described.

In the use of this pad, the tubular mem-. here 2 are engaged by the upright supporting pins 7 which are carried by the ribbon vibrator. These pins 7 are here shown' having hook-shapedends whichenter the tubes 2 and they are fixed in arms 8 of the vibrator 9. The'ribbon-vibrator 9 and guide,10 which are of usual construction, are also employed for holding the pad in operative position and between which the type is designed to operate, the pad being shaped in exactly the same manner as is the ribbon.

In the use of this pad, the silk side 6 is. disposed; next to the paper and the keys come in contact with the cotton inking layer 5. This pad may bereinked with the same T ink which is used by manufacturers in inking ribbons and when found necessary may be removed and another substituted.

By so constructing the pad, the life thereof is greatly prolonged and the type are prevented from being clogged, thus dispensing with the work which usually "falls to the typist-of cleaning such type,'and the .replacing of new ribbons, is also dispensed with, which is very laborious aswell as dirty.

From the foregoing description, taken in connection with the accompanying drawings, the advantages of the construction and of the method of operation will be read ly apparent to those skilled in the art to which the invention appertains and while I have.

described the principle ofoperation of the.

invention together with the device which I.

now consider to be the best embodiment thereof; I desire to have it understood that thedevice shown is merely illustrative and that such changes may be made as are withln the scope of the claimed invention.
