PAPER-GAGE.

lSpecication of Letters Patent.

To @ZZ whom, t may concern.-

Be it known that I, WILLIAM SMITH, a subject of the King of Great Britain, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Paper-Gage, of which the following is a full, clear, and exact description.

My invention relates to paper-gages for machines for reproducing by stencils and the like.

Although capable of general use, I have chosen to illustrate my invention as applied to the apparatus which forms the subjectmatter of my Patent No'. 639,623, granted December 19, 1899. That machine was de signed for use with sheets of paper of one size. The principal object of my present invention is to provide means whereby machines of this general character can be operated in connection with sheets of different sizes. For this purpose I provide movable or adjustable paper-guides on the plunger of the machine and locate registering marks onv the plunger, stencil-holder, and stencil.

Another object of my invention is to provide for locating the printing portion of the stencil in any position that may be desired in view of the particular size of paper that is to be used.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a longitudinal sectional view taken on a vertical plane through a portion of an apparatus of the character hereinbefore referred to, showing my invention applied thereto. Fig. 2 is a plan of the plunger. Fig. 3 is a bottom plan of .the stencil-holder and stencil; and Fig. 4 is a sectional view, on an enlarged scale, of one-of the gages.

The table 10 of the machine is provided with a well 11, as usual, for the reception of the plunger 12. This plunger may be operated in any desired manner in order to force sheets ofvpaper 13, supported onits upper surface, against the under surface of a stencil 14. This stencil is shown as being supported is a stencil-frame 15, which is provided with a peripheral groove 16 for receivingthe edge of the stencil and a stencil-holder 17. The stencil-frame may be secured over the opening in the table by set-screws 18, as has been shown in my. aforesaid patent. The drawings also illustrate a front opening 19 in the well, through which the plunger extends. In my previous machine the arts were so proportioned that they would) receive a desired size of paper-as, for example, foolscap.v

` In order to 'fit the machine for operating upon paper of several different sizes, I provide the plunger with longitudinal grooves 20. In these grooves I place gage-pins 21 and mount these pins in such a manner that they can be adjusted alongthe grooves and secured in any desired positiontherein. It is intended that the edges of the pile or pad of paper upon which the impressions are to be made shall engage with the sides of the pins and be thereby fixed in the position which is desired. In order to provide for securing the pinsv in adjusted positions upon the plunger and for mounting them in such a manner that they will yield when they approach the stencil on the upward movement of the plunger, I provide pin-holders 22. Each of these holders is preferably in the form of a tube having a flange 23 upon its upper end, this iiange resting in a counter# sunk opening 24, surrounding the slot 20, and the top of the flange being flush with the top of the plunger. The tubes may extend down below the bottom of the plunger and are provided with closed lower ends, and in said tubes are mounted springs 25 for supporting the plungers and keeping them in elevated position. Each tube is also provided with means for securing it to the plunger in any adjusted position, this being illustrated in the form 0f a nut 26, engaging screw-threads 27, on the outside of the tube. A washer 28 is also shown above the nut. I have shown .a stationary bar 29 and an adjustable bar 30 across the bottom of the stencil. The latter bar is adjusted so as to engage the pins 21.

In order to provide for indicating the positions at which the pins are to be set, I have shown a series of transverse lines indexedor marked 1 2 3, &c., across the surface of the plungernear one edge. The corresponding edges of the stencil and holder are also provided with similar lines indexed or marked in the same way. I have also shown the plunger, stencil, and holder as being provided with a series of longitudinal lines in- IOO IOS

deXed or marked a b c d, Sac. The lines of each set are designed to register with the lines designated by the same characters of the other sets.

The manner of using the device and the operation of the parts is very simple. With the paper that is to be printed upon placed upon the plunger or upon a stencil-sheet the operator can readily see the position in which the printing parts of the stencil will have tov come and can locate the same with reference to the numbered and lettered lines on the stencil or plunger. stencil-sheet in av type-writer and locate the characters at the desired points, so that they will print in the desired place on the paper when the paper and stencil are placed in proper position on the machine. When prepared, the stencil is placed on the holder and centered by the lines, so that the lines on it will register with the corresponding lines on the plunger. The pile or pad of paper is then placed on the plunger with two edges flush with the edges ,of the plunger. When this has been done, the operator adjusts the gage-pin holders 22 in the slots 20 so that the pins will come against the rear edge of the paper. When the plunger is elevated to bring the paper into contact with the stencil, the top of the gage-pins will engage with the bar 30, and the pressure exerted will force them downwardly against the force of the spring 25. It will be found that each sheet is printed in the predetermined place.

Instead of the marks on the stencil-holder there can be used any registering device which will insure that the stencils will all be placed in the proper position with respect to the holder, which holder is of course held in registration with the plunger by the walls of the well.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1.
