This invention relatesito a typewriter attachment particularly adapted for use in p eparingstencil sheets i such as disclosed ,tor

- exampleiin my copending application Serial No. 552,792, 'Ifiled .April 14, 1922, but s tachments embodying the ,present invention are also applicable ioruse in typing cards or other sh etsof paper. r r In order more clearly to illustrate the natureoi the invention, I .have shown one concrete embodiment inthe accompanying drawingmin whi ch Fig. 1 is arfront elevation-of the attach- Inent, portions ofthe typewriter bemg shown to illustrate its relationship with the typewriter;

Fig. 2,is an end view of the device;

Fig. "3 is a section on the line 3-3 0t, Fig. 1; v

Fig. & is a plan view showing the attachment modified for mounting on a different form of typewriter;

Fig. 5 is a section on the line 5-5 of FigA; 1 V

Fig. 6 is a fragmentary view of still another mounting for the attachment; and

Fig. 7 is a section on the line 7-7 of Fig. 6.

The particular embodiment of the invention chosen for the purpose of illustration comprises a frame preferably of aluminum made up of a back 1 and end members 2, integral with the back and extendlng at substantially right angles therefrom. The end members 2 are connected together at the top by a strip. 3, the ends of which are bent over the outside of the end members 2 and secured thereto by rivets. The bottom of the end members 2 are connected together by a rod & which is held in place by screws. In order to fit around a platen P of the typewriter the lower ends of the end members 2 are out out at 5, slightly rearwardly of the rod 4. Formed in each of the end members 2 are slots 6 (Figs. 1, 2 and 3) to receive the bar B provided on the carriage of a wellknown make of typewriters, and spring pressed hooks 7 pivoted by means of rivets 8 hook over the bar B to hold the attachment in place. As mounted the back 2 rests against the guide plate G usually provided on these machines for guiding the paper fed to the platen.

that the paper is guided to the platen P by the back '1, and from the platen by the ro' di l 4 under which it passes to the'guides '9, the

strip cooperating with the guides-to posi} tion the stencil sheet or 'otherpaper so that it is accurately positioned in planes substan-c tially perpendicular to the axis of thepla cn In this .way the marginof the typewritten matter may be made exactly parallel to the? margins of the sheet and by using the ordi nary carriage stops the margin oifthe type:

'As shown inFigs. 4 and 5 the.,attachment may be provided with v other, means for mounting on typewriters of another wellknown make, and in this form the back 2 is formed with a longitudinally extending lip 11 which hooks over the paper guide plate R usually provided on these machines. In order to hold the attachment in position arms 12 and 13 are secured by rivets to the end members 2 respectively, extending at substantially right angles therefrom, and the arm 13 is bent to fit over the usual slide S on the guide plate R. The outer ends of the arms 12 and 13 are bent rearwardly to receive screws 14; which are adapted to bear against opposite ends of the plate R thereby securely holding the attachment in proper position.

In order to mount the attachment on still another well-known make of typewriter, which is usually provided with a substantially vertical paper guide plate H, arms 15 (Figs. 6 and 7) are secured to the end mem-' bers 2 respectively and are provided adjacent their outer ends with clips 16 which are adapted to fit over the edges of the plate H, screws 17 being provided to hold the clips to the arms and draw them into engagement with the plate.

An outstanding featureof the invention consists in that the paper is guided to and from the platen and that the unitary core struction contributes to accurate positioning of the sheets. This also facilitates and renders more easy the cutting of stencils bethe guides in predetermined spaced relation,

and spring held means for detachably connecting the attachment to a typewriter i operative relation to the platen. I

2. A typewriter attachment comprising .means for guiding the paper, and catch means for detachably connecting the attachment to a typewriter in operative relation to frame parts of the platen, said guiding means including straight elongate guides for the edges of the paper after the paper passes over the platen and a pair of guides in juxtaposed relation to the front face of the straight guides.

3. A typewriter attachment comprising a frame, a spring pressed hook adapted to detachably mount said frame on a type writer adjacent the platen, said frame having means for guiding paper to the platen, opposed guides for the edges of the paper where it leaves the platen, and meanscooperating with said guides for positioning the paper transversely and longitudinally of the paper. 7

4:. A typewriter attachmentlfor guiding paper to and from the platen comprising a guide frame having a back and opposed parallel sides, hook means adapted to detachably connect said guide frame to the typewriter frame, guides on said sides in opposed relation arranged to guide the edges of the paper where it leaves the platen,

a member connected to said sides adjacent the lower end of the frame under which the paper passes from the platen, and a member connected to said sides adjacent the top of the frame cooperating with said guides for positioning the paper. 7 c

5. A typewriter attachment for guiding paper to and from the platen, comprising a frame having a back and opposed parallel sides, guides on said sides in opposed relation arranged to guide the edges of the paper when it leaves the platen, a connecting member for said sides adjacent the lower end of the frame adapted to form a guide for the paper adjacent the front of the platen, and a connecting plate for the front of said sides adjacent the top of the frame adapted to hold said paper in position when it has lcftthe platen.
