FEED-GAGE FOR PRINTING-PRESSES.

To all whom it may concern:

Be it known that I, LOUIS A. LIEBS, a c1t1- zen of the United States, residing in the borough of Bronx, city and State of New York, have invented a Feed-Gage for Printing-Presses, of which the following is a specification.

My present invention relates to a printing press, and particularly to the feed gages employed in a platen press for determining the position of the material upon which an impression is to be made by the type form fixed in the press.

The feed gage made in accordance with my invention preferably comprises a socket and a stud member. The socket member of each. feed gage is secured in position in the chase or type frame, together with the type, which is fixed in the frame of the machine, as is usual. The stud member of each feed gage is preferably angular, one arm thereof being adapted to enter its socket when the platen is operated to bring the inaterlal upon which an impression is made 1n contact with the type for this purpose, the other arm of each stud member being suitably secured to the material forming the surface of the platen, all of which will be hereinafter more particularly described.

In the drawing, Figure 1 is a perspective view, illustrating the chase frame and platen of a printing press. Fig. 2 1s a per spective view of a stud member of my 1mproved feed gage, and Fig. 3 1s a similar view of the socket member thereof.

Referring to the drawing, A indicates the bed or frame of a platen printing press, adapted, as is customary, to receive the chase of the type frame B, while 0 indicates the platen, which is suitably hinged to the bed A and may be actuated in any customary manner known to this art.

The feed gage made in accordance with this invention comprises a socket and a stud member. The socket member is indicated at G and, as shown in the drawing, is preferably rectangular and provided with a recess E. it This socket member is secured in positionv in the type frame or chase B, together with the type form, in any suitable manner. As indicated in the drawing, I prefer to use two of the socket members on one side of the type form and one socket member on another side of the type form, although, as will be understood, any number of these Specification of Letters Patent.

parts may be employed to form an angular gage, as hereinafter described.

The other part of the type gage is a stud member crmnn-ising arms I) and H, at right angles to each other, the arm 1) being adapted to enter the recess E in its socket member, while the under surface of the arm H is provided with a suitable adhesive material in order to secure the same in position on the material forming the surface of the platen C.

In the use of the hereinbefore described feed gage, the desired number of socket members (lare suitably placed in the type frame B, together with the type F, and the chase is placed in position in the bed of the press. The corresponding stud members are then placed in position in their re spective socket members, after having the outer surface of the arm H of each stud member suitably provided with an adhesive material.

It is to be understood that the height of the combined socket and stud members, when in position, that is to say, a distance from the base or inner end of the socket members and the thickness of the arm H of the stud members, is the same or substantially the same as the height of the type, so that when the stud members have been placed in position, as hereinbefore described, the platen is operated to bring the material upon which an impression is to be made therefrom against the surface of the type, the outer faces of the arms H of the stud members will be brought positively into contact with the material forming the surface of the platen (l, causing these stud membcrs to adhere to the surface of the platen so that when the platen is moved away from the frame, these stud members will adhere to this surface and form an angular gage for the stock material to be printed.

From the foregoing, it will be readily understood that my invention provides a quick and absolutely certain method of determining the relative positions of the type in the type frame or chase to the material upon which the type is to make an impression.

I claim as my invention:

1. A feed gage for platen printing presses, comprising a stud member and a socket member, one of which is adapted to be secured in a type form and the other provided with an adhesive surface so that when the platen of the press is brought to a closed position, after the said stud and socket members have been placed together and both are supported in the type form, the member with which the platencontacts adheres thereto and is positioned thereon as a gage.

2. A feed gage for platen printing presses, comprising a socket member, a-stud member, a portion of which is adapted to enter a recess provided therefor in the socket member, the combined length of the socket and stud members, when. in position, being equal to the height of the type employed in the press, one of the said members being adapted to be secured in the type form and the other to be fixed to the platen so as to come into contact with one another each time the platen is operated.

3. A feed gage for platen printing presses comprising a socket member adapted to be secured in position with the type in a type frame or chase, and an angular stud memher, one arm of which is adapted to enter a recess in the socket member and one surface of the other arm of which is adapted to be secured to the material forming the surface of the platen of the press.

4:. A feed gage for platen printing presses.

of the platen of the press, the combined length of the said stud and socket members, when in their relative positions, being substantially equal to the height of the type employed in the press.
