GAGE'FOR MANIFOLDING APPARATUS.

srncrmcncrrolv forming part of Letters Patent No. 522,447, dated July 3,1894.

Application filed October 10, 1 s93.

. in place.

It also consists in certain details of construction which will bemore fully explained by reference to the accompanying drawings, in which- Figure 1 is a view showing my invention ap plied toa mimeograph printing apparatus, showing the upper frame partly open. Fig. 2 shows the mechanism on the bottom of the frame. g Y

The object of my invention is to provide easily adjustable gages against which the sheets to be printed upon are placed, while the frame is open, and a means for retracting the gage points as soon as the frame is closed for the purpose of reproducing the letter orother matter.

. slides D which fit upon bars E beneath the bed A of the apparatus as shown. These slides have an elastic side or springs D which are adapted to press against the sides of the bars E with a sufficient tension to hold the slides and the upwardly projecting gage pins at any point where they may be laced, and at the same time to allow these sli es and pins to be easily moved to fit the work to be done. It will be manifest that as many of these adj ustable pins and slides may be employed as may be desired. I have found that two, movable longitudinally to receive the upper edge of 'the'sheet, and one to form a side gage, are

7 sufficient for most Work. city and county ofS'an'Francisco, State'yf ThelbaFQQE upon which the slides moveare, hinged or pivoted -tothe lower edge of the frame-within which the'bed is contained, so

that the opposite ends are movable about the hinge points. One of these barsi's' bent around in rectangular form sothat an arm E extends along beneath onev side of the frame of the bed, and has a projection or spur E extending slightlybeyond the edge of the iframe/ A A Eris a thin plate of metal, one end of which rests upon the projecting spur E oris otherwise connected with it, and the other end is pivoted to the hinge pinof the upper part of the frame G. The hinges H of the upper part of the frame extend a'little distance from the hinge point toward the lower end, and are then bent upand connected withjthis upper part of the'frame as shown. Upon the plate F is a projecting pin or spur F'in such a position that when the upper frame is closed down upon thelower one, the extension of the hinge engages this pin and presses itdown. The plate F, by reason of its fulcrum point and the long arm which engages the projectionE is depressed about its hinge point when the frame is closed, and thusacts to depress the spur E and simultaneously the remainder of the hinge frame E, thus carrying the upwardly projecting gage points down below the surface of the bed so that the work of printing the copy is carried on in the usual manner without injury to the stencil paper, or forming contact with these gage points. As soon as the frame is raised, the elastic spring I which acts upon some part of the bars E, lifts them up and again projects the gage points up through the bed-plate.

It will be seen that by this construction, the sheets of paper are rapidly placed in exact position against the gage points, and as soon as this is done, and the frame closed, the. points being of no further present service will be retracted beneath the bed and the rest of the operation of printing can be carried on without damaging the sheets or-other part of the copying mechanism.

Having thus described my invention, what I claimas new, and desire to secure by Letters Patent, is-

1. The combination with the longitudinally slotted bed and the hinged frame, of a gage adjustable longitudinally of and adapted to project through said slot, and means for automatically retracting and projecting the said gage upon the opening and closing of the said hinged frame, substantially asherein described.

2. The combination with the longitudinally slotted bed, and the hinged frame, of a gage adjustable longitudinally of and adapted to project through said slot, a movable bar or carrier below the bed and on which said gage is mounted and means for automatically moving the bar or carrier to project and retract the gage by the opening and closing respectively of the said hinged frame, substantially as herein described.

3. The combination with the longitudinally slotted bed and the hinged frame, of a movable spring pressed bar or gage-carrier beneath the bed, and operated against the action of its spring by the closing of the said hinged frame, and a gage carried by the said bar or carrier and adjustable thereon to register with any portion of said bed slot, substantially as herein described.

4. An impression bed having slots or channels made through it, movable bars extending beneath the channels of the bed, slides fixed to said bars and adjustable thereon, and gage points projecting upward from the slides through the slots and above the surface of the bed, whereby the sheets are properly adj usted, and means for depressing the bars and gage points after the sheets are placed, substantially as herein described.

5. The impression bed having channels made through its surface, bars extending beneath the bed hinged at one end and having spring-actuated slides fitted to them, with'up- Wardly projecting gage points extending through the slots and adjustable with relation to the surface of the bed, ahinged frame adapted to close above the bed, a lever fulcrumed to the side of the bed having one end engaging a projection from the gage carrying bars, and a pin adapted to be engaged by the hinged frame when the latter is closed over the bed whereby the bars and the gage pins carried by them are depressed below the surface of the bed by the closing of the upper frame, substantially as herein described.

6. A bed adapted to receive the sheets upon which the copy is to be taken and having slots or channels made through its surface, bars extending in line beneath said bed and hinged to one end of its frame, adjustable slides fitting said bars having upwardly pro jecting gage pins extending through the slots in the bed toa point above its surface, whereby the sheets are accurately placed upon the bed, a frame hinged to the bed and adapted to close down over it after the sheets are in place, a lever hinged to one side of the bed having a pin which is engaged by the hinged frame when the latter is closed, the opposite end of the lever engaging a spur from the gage carrying bars whereby the gage pins are depressed beneath the surface of the bed when the hinged frame is closed, and a spring whereby the bars and gage pins are elevated when the frame is open, substantially as herein described.

In witness whereof I have hereunto set my hand.
