FEED GAUGE PIN. l 3.1;-

Application filedJuly 9,

This invention relates to improvements in feed gauges for use on prmtmg presses, and is more particularly adapted to a feed gauge pin which is to be secured'on the tympan sheet of a platen printing press.

One of the important objects ofthe pres ent invention is to provide a device of the above mentioned character which may be readily and easily secured on the tympan sheet to facilitate the feeding of the sheets to be printed to the press and regulate and maintain the proper position of the same as the are presented to the type. r

A urther object is to provide a feed gauge pin of the above mentioned character wherein the paper engaging face "of the body portion of the gauge pin is relatively broad and smooth so as to prevent the edge of the paper from being dented when it strikes the pin and hanging thereto.

Furthermore the pin is provided with a depending tooth which is arranged adjacent the front smooth face of the body portion, the same being adapted to bite into the tympan sheet and to prevent the paper from hanging on the bottom edge of the A still further object is to provide a feed gauge pin of the above mentioned character which is simple in construction,inex- ,pensive, and furthermore adapted to the purposes for which the same is designated.

Other objects and advantages of this invention will become apparent during the course of the following description.

In the accompanying drawing forming part of this specification and in which like numerals are employed to designate like parts throughout the same: 7

Figure 1 is a top plan view of the feed gauge pin embodying my invention, showing the same secured on a tympan sheet,

Fig. 2 is a bottom plan view of the gauge pin per se,

Fig. 3 is a side elevation, and

Fig. 4 is a longitudinal sectional view.

In the drawing wherein for the purpose of illustration is shown the preferred embodiment of my invention, the numeral 1 designates generally my improved feed gauge pin, the same comprising the substantially rectangular body portion 2 which is formed of any suitable metal. The forward edge of the body portion provides the sheet engaging face 3, the same being very smooth.

1925.. Serial No. 42 ,502.

Dependin from the bottom of the body porupwardly and extending into the body per-- tion2 as illustrated at 7, the major portion of the pin being disposed rearwardly of the body along the bottom thereof and terminates in the sharpened point 8. This point is adapted to be inserted into the tympan sheet 5 in the manner asclearly illustrated in Fig. 1 so that the tooth 4 will provide a meansfor properly positioning.-

and supporting the gauge pin on the tympan sheet of a platen press.

Also extending rearwardly from the body portion 2 of the feed gauge pin are the pressure members 9 and 10 respectively, the same being arranged on opposite sides of the prong 6 and being also formed of any suitable wire. The rear free ends of these strands of wire are bent downwardly and thence upwardly to provide the tympan sheet engaging feet 1.1. The purpose of the provision of these pressure members is to provide a means for forcing the feed gauge pin downwardly against the surface of the tympan sheet tending to eliminate the slipping of the feed gauge pin from its proper position on the tympan sheet.

The feed gauge pin is further provided with the usual paper engaging tongue 12,

the same being formed of a single or double strand of wire and extending longitudinally through the body portion 2 in the manner as clearly illustrated in Figs. 1, 2 and 4 of the drawing. The rear end of the strand of wire forming the paper engaging tongue is coiled about one of the pressure members as illustrated at 13 and the forward free end of this strand of wire projects beyond the forward smooth edge of the body por tion for a suitable-distance as is also shown clearly in the drawings.

\Vhile I have shown only one of such tongues, it is to be understood that one or more tongues may be provided as is desired and necessary as I do not wish to limit myself to the particular number of tongues. The purpose of the tongueis to keep'the paper from curling up and riding over the no I pin as frequently occurs when such a tongue is not used,

\Vith the mechanical platen press feeders now generally used, paper is fed to these gauge pins at right angles with their face and usually at great speed. The wide smooth face 3 of my improved gauge pin will prevent the edge of the paper from be ing dented when it strikes the pin and hanging thereto. Also the provision of the tooth t will prevent the paper froinhanging on the bottom edge of the pin, thus eliminating a great deal of trouble which is ordinarily experienced in register work.

The simp-licity'w-ith which my improved feed gauge pin is constructed enables the same to be readily and easily attached on the tympan sheet so that it will not become accidentally disengaged therefrom. Fun t-hermore a device of the above mentioned character may be manufactured at a very low cost and will be strong and durable.

\Vhi le I have shown the preferred embodiment of my invention, it is to be underand arrangement of parts may be resorted to without departing frem the spirit or and-having its front face flush with the forward edge of the body portion, the bottom edge of the tooth being sharpened and adapted to bite into the tympa-n sheet, a prong extending along the bottom of the rear portion of the solid body, the forward end of said prong being bent upwardly and v disposed within the body portion, therear end of the prong being pointed and extending rearwardly from the "body portion and adapted to be inserted in the tympan :sheet, pressure members extending rearwardly from the body portion on opposite sides of the prong, the rear ends of the pressure members terminatingin tympan sheet engaging feet, and a tongue projecting from stood that various changes in the size, shape the forward end-of the solid body portion;
