WORK-GUARD FOR TYPE-WRITING MACHINES.

sEEGIFICATIONVfoi-mng part of Letters Patent No. 747,953, dated December 29, 1903.

Application filed December 5,1900. Serial No. 38,806. (No model.)

To all whom it may concern: v

Be it known that I, HERMAN F. ECKERT, a citizen of the United States,residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a new and useful Work-Guard for Type-Writing Machines, of which the following is a specification.

This invention relates to type-writing machines, and has special reference to means xo for protecting and also for assisting in the holding of a card, sheet, page, or other piece of work in the printing position.

To this end the invention primarily contemplates a work-guard for type-writing machines adapted to engage with the top or' bottom edge or other portion of the work to serve as a protector therefor during the-printing operation, as well as an auxiliary holder to assist in holding the work in the printing zo position.

A further object of the invention is t0 provide a Work-guard of the character specified possessing special utility with book and loosesheetv work in connection with book typez5 writing machines of that type embodying a flat platen and a travelingy printing mechanism working thereover. With machines of this character the invention may serve to clamp or grip the top edge or other portion 3o of the sheet or other piece of work to prevent shifting or slipping thereof, besides serving chietly to protect the edge of the work from contact with the traveling frame of the machine or any of its mechanism.

l Another object of the invention is to provide a novel arrangement and mounting of the work-guard forthe top edge or other portion of the work which shall be movable or shiftable in the direction ot' line-spacing, th us 4o permitting of the sheet, page, or other work being protected and held bythe guard at any point on the platen within the printing area.

`The invention alsocontemplates an arrangement of work-guard possessing special value in billing or indexing work where the bills orcards are being printed and duplicate impressions transferred to an underlying page or sheet and the bills, cards, or other pieces of Work are variously positioned with 5o respect to said underlying page or sheet.

In a broad aspect the invention has for its object to provide, in connection with suitable holding means, a work-guard coperating with said means and adjustable to any posi- `tion within the printing area; also, to proplat-en in the direction of line-spacing, but I principally designed'for engagement with the top edge of the work.

With these andmany other objects in view, which will be readily apparent to those familiar with the art as the nature of the in- 7o veution is better understood, the same consists in the novel construction, combination, and relation of parts hereinafter more fully described, illustrated, and claimed.

While the work-guard attachment is necessarily capable of general application and is susceptible to a variety of modifications both as to the form thereof and its relation to the other parts of the type-writing machine, still Vfor illustrative purposes there is 8c shown a practical embodiment of the invention in the drawings, in which- Figure l is a plan View of the platen and guide-rails of a book type-writing machine, showing the Work-guard associated therewith in the manner contemplated by the present invention. Fig. 2 is a transverse sectional view on the line 2 Zof Fig. l. Fig. 3 is a detailin perspective of one form of workengag ing member or clamp which has been found 9o useful in carrying out the invention. Fig. 4 is a cross-Sectional view of the same. Fig. 5 is a detail in perspective of a modification, showing the Work-engaging member or clamp fitted with auxiliary bearing-springs to provide a positive grip for the work. n

Like nu me'ralsof reference designate corresponding parts in the several ligures of the drawings. f 'l The present invention contemplates the roo idea of utilizing, in connection with a typewriting machine, a Work-guard adjustable in the direction of line-spacing and arranged to protect, as well as to assist in holding, the sheet or other work at any point within the printing area. This idea may be embodied in a variety of structures and utilized in connection with diifereut types of machines, although the same possesses special utility in connection with the fiat platen of a book type-writing machine. Hence for illustrative purposes one embodiment of the invention is shown in the drawings in connection with the'tlat platen and guide-rails of a book type-writing machine, said platen and guiderails being designated, respectively, by the numerals l and 2. No claim is made in the present application to the mounting and arrangement of the platen and guide-rails, although there is preferably shown the same construction and relation of parts utilized in connection with the Fisher book type-writing machines such as are now upon the market.

In adapting the invention to a fiat-platen type-writing machine there is employed a work-engaging member 3, which is arranged for adjustment over the platen l in the direction of line-spacing. This Work-engaging member may be of any desirable form and constructed of anysuitable material; but for illustrative lpurposes it is shown in the drawings as consisting of a web or plate, preferably of a sufficient length to extend across the interval between its oppositely-located guide-rails 2, upon which the printing mechanism is mounted to travel in the usual manner. The said web or plate 3, (shown in the drawings,) may be mounted for adjustment in connection with any suitable holding means or both holding and guiding means therefor without departing from the spirit of the invention. Various mechanical -eX- pedients for securing these results will naturally suggest themselves to a mechanic; but a construction which may be resorted to is shown in the drawings and consists in providing the guide-rails 2,atthe inner sides thereof, with longitudinally-extending grooves 4, which slidably receive the opposite end edges of the work-engaging member or web 3, and therefore constitute both holding and guiding means for the same. The slidable engagement of the end edges of the work-engaging member or web 3 within the grooves 4f can be made sufficiently snug to provide for the frictional retaining of said member or web in an adjusted position, while at the same time not interfering with a shiftable or sliding movement to any desired point within the printing area of the platen.

In the form of work-engaging member or clamp 3 shown in the drawings the same is made sufficiently thin, so as to have no interfering projection above or below the plane of the guide-rails, and therefore presents no obstruction to the operation of the machine and the movementthereof over the guiderails 2. If found desirable, thin clamping edges may be provided upon opposite sides of the member or web by forming longitudinal edge bevels 5, although this and other expedients in the structural details will be left to the judgment of the manufacturer. However, in the form of the invention being described it may be found desirable to provide the work-engaging member or web 3, at the opposite ends thereof, with slide arm extensions 6, which provide an extended bearing for the member or web and the holding and guiding grooves 4 therefor.

Under some circumstances it may be found sufficient to provide the work-engaging member or web 3 with a dat gripping or contact surface at the under side thereof, while under other conditions it may be found desirable to mill or roughen such surface, so as to engage with the sheet or other work with sufficient firmness to materiallyassist iu holding the same against slipping. It may also be found desirable to resort to such devices as auxiliary bearing-springs 7, fitted to the under side of the engaging member 0r web, contiguous to the edge thereof, and adapted to provide a positive grip for the work when the member or web is engaged therewith.

Various other modifications along the lines indicated will readily suggest themselves without further elaboration thereof and without illustration of other modifications, as it will be understood from the foregoing that the essential feature of the invention resides in the mounting of the work-guard in such a way as to permit of the same being adjustable in the direction of line-spacingand adapted to be arranged upon the work at any point within the printing area of the platen. Furthermore, in the construction described the work-engaging member iscarried by the guide-rails, so that when these rails are lifted from the platen or work the said member or web will be carried therewith to a position out of the way, thus permitting a sheet or other piece of work to be readily removed from the platen or placed in position thereon-- that is to say, the work-engaging member is mounted to be operated by the rails in the movement of the latter toward and from the platen, it being obvious that these rails, connected at their front ends bya bar and hinged at their rear ends, as shown in the drawings, constitute a supporting-frame for the writing mechanism. The work holder or guard is therefore arranged to automatically engage and hold the sheet upon the platen and is capable of being shifted in the direction of linespacing.

[t will be observed that the use of the workguard herein described in connection with.

IOO

ent positions. Various other kinds of book and loose-sheet work can be carried out with better facility, accuracy, and neatness by the employment of a Work-guard embodying the novel features of the present invention.v In some cases the work-guard is chiey designed for engagement with the top edge of the bill, sheet, or other piece of work, so as to not only assist in holding the same, but principally toact in the capacity of protector for such Work from contact with the traveling machine-frame or any of its mechanism. It will be obvious, however, that the said guard could be shifted to serve as a protector for the bottom edge of the work, or by the employment of a pair of the guards both the bottom and top edges of the work may be protected and held in the manner explained. It will also be obvious that should the conditions of the Work require it the guard could be shifted to any point thereover within the printing area.

From the foregoing it is thought that the construction, use, and many advantages of the herein-described workguard will be readily apparent Without further illustration or description, as it will be understood that various changes in the form, proportion, and minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this in- Vention.

Having thus described the invention, what is claimed as new,and desired to be secured by Letters Patent, is-
