rnEmrEED GAGE.

in the art to which it appertains to make and use the same. The invention relates to gages for machlnes lnvolving mechanlsm for operation upon sheets or webs of paper and otherfmaterial, and has for its object to provide a novel form of sheet gage, with electrical adjust the gage either from a point immediately adjacent'the gage or from some remote point, as forexample, the usual position Or station of the operator in charge of the apparatus. Gages of this character are extensively employed in printing presses, but their application is also general to other machines.-involving the feed of' sheets or webs, and it is to be understood that the present invention is applicableto gages of this character generally.

The invention is illustrated in the accompanying drawings in which,

invention as end gages and a side gage. Fig. 3 is an enlarged side elevation, partly in section, of one of the gages. Fig. 4 is a vertical transverse section of the gage on line H of'Fig. 3.

Application filed November 27, 1915. Serial No. 63,892.

the feed board C is a side gage G involvlng the invention hereinafter to be more particularly described. Mounted upon the usual rock shaft E are two front gages G, G, also involving the principles of construction andpperatioh which characterize the present lnventlon.

The means for adjusting and operating I the front and side gages G, G respectively are practically identical and a description of these means in connection with the front gage will also serve in respect. of theside gage and gages for other purposes in machines involving the feeding of sheets or Webs of paper and the like.

Each of he frontgages involves an annular bracket piece 2 adapted to be secured by the usual form of clamp 6, to the rook shaft E. Slidably mounted on-the horizontal member of the bracket 2 is a gage arm or support 1, which is locked to the bracket 2 by means of a set screw 4 carried'by the bracket and engaging a slot 3 in the gage arm 1. The rear portion ofthe gage arm 1 is provided with an angular offset, in which is journaled a set screw 5, which engages a threaded opening in the bracket 2, and by means of which the ordinary coarse or rough adjustments of the gage may be effected, as will be understood.

The forward end of the gage arm 1 is provided with a downward angular extension 10, adjacent to which and secured to the under face of the arm 1 is a U-shaped frame or yoke 11. In the latter, there is journaled a gage spindle 12- capable of rotary movement, but held against longitudinal movement by suitable collars engaging the exterior faces of the yoke or frame 11. The forward end of said spindle 12 is provided with a screw thread 13 and upon thls screwthreaded portion of said spindle is mounted a threaded yoke 14: provided with forwardly extending pins 15 to the outer endof which is secured gage plate.16,' which latter is provided with the 'usual spring guard 17 It will be understood, of coiirse, thatas the spindle 12 is rotated in one direction or the other, the gage plate 16 will be moved toward and from the vertical member 10 of the gage arm, and as it is proposed to operate the spindle 12 by a step by step movement, it will be apparent that exceedingly close and fine adjustments of the gage plate 16 may be effected.

Secured to thespindle 12 is a sleeve-like member having two ratchet rims 20 and 21 thereon, between which is located a locking ratchet member 22 provided with a series of peripheral openings, more particularly illustrated in Figs. 5 and 6. The ratchet members 20 and 21 areoppositely disposed so that when they are separately actuated, the spindle will be rotated step by step in a clockwise or an anti-clockwise direction, depending upon which or the i'atchets is actuated.

The operating means for the ratchets 20 and 21 consists of a novel form of electromagnetic motor, consisting of two pairs'of solenoids, 25, 26 and 25 26 respectively. As these solenoids and their appurtenances are practically duplicates, it will be necessary to describe in detail one pair only. The pairs of solenoids are mounted on the under face ofthe gage arm 1 and within the yoke or frame 11, as shown in Figs. 8 and 4. Reciprocably mounted in the coil -of solenoid member 25 is a core 27 provided .with an angularly disposed lower end 27,

ciprocating core 28, the lower end. of which is recessed to receive the forward end of core section 2?, when the solenoid members are energized. Normally, the core sections 27 and 28 are held apart, so as to disengage pawl 29 from ratchet 20, by means of a helical spring 81, mounted upon a pin 30,

secured to core 28 and projecting through an opening 32 in the end of core section 27', as particularly illustrated in Fig. 7. This relation of the core members 27 and 28 maintains the pawl 29 out of engagement,

with corresponding ratchet 20. When, however, the solenoid members 25 and 26 are energized, the core members 27 and 28 are immediately magnetized so that the lower angular member 27 of core 27 is attracted to and held by the lower end of core 28, against the tension of spring 31, thereby bringing pawl 29 into engaging relation with ratchet 20. Practically simultaneously, or at least, but a short interval. after this operation, both cores 27 and 28 are lifted by their respective solenoid coils so that the pawl 29 turns the ratchet 20 and with it the spindle 12, one step, equal to the upward movement of the solenoid cores, which is substantially equivalent to the rotary advancement of the ratchet 20 and the spindle 12 a distance equal to one ratchet tooth. It will be understood that inasmuch as the opposite pair of solenoids The 1,1eaeca the solenoids 25 and 26.

Mounted centrally of the solenoid members 25 and 26, and 25 and 26 is a further solenoid 35, having a core 36, the lower end of which is provided with a stop or detent 37 adapted to engage'and cooperate with the peripheral openings in the lock member 22, located between the ratchets 20 and 21 on the spindle 12. Normally, the solenoid core 36 is in its lower or locking position, with the end 37 thereof engaging the subjacent recess in the locking mem ber 22, as shown in Fig. 6, thereby holding the spindle 12 and age plate 16 rigid and immovable, even wlien the gage is subject to the jars and shocks of operation, or even bodily movement, as is the case in certain types of presses. When, however, the solenoid 35 is energized, its core 36 is retracted, releasing the spindle l2 and permitting the same to be rotated in either direction to effect the finer and accurate adjustments of the gage plate 16. As indicated, the adjustment of the spindle 12 and gage plate 16 is eliected by the respective sets of solenoids 25, 26 and 25, 26.

In order to energize the respective solenoids of a given gage, these solenoids are connected in circuit with a source of electric energy Y, see Fig. 9, which circuits are controlled by'push buttons or circuit closers, one set of circuit closers being located preferably on or adjacent to the gage proper, and the other set of circuit closers being located on the machine to which the gage is applied and in a position to be reached by the operator of the machine without the latter leaving his position, such position being, in the machine illustrated, the delivery end of the press A, where the operator can watch the sheets as they are delivered and determine instantly whether the gages are properly set. The circuit closing elements preferably consist of push buttons p and p, which are located at the point of distant control, and push buttons [0 and p", which are preferably attached to the gage arm 1 adjacent to the solenoids, as indicated in Figs. 3 and a. Suitable cables or conductors X serve to establish connection between the source of electric energy Y and the solenoids 25, 26 and 25*, 26 and solenoid 35, when the corresponding push buttons or circuit closers p, p, p, and p" are operated, as will be understood from. the wiring diagram shown in Fig. 9, which represents the electromagnetic actuating and locking means for a single gage. It will be noted that the solenoid 35 is so connected with the energizing circuit that it is included in circuit with either set of the operating sole- -without leaving his position, he presses the cuits for said electromagnetic operating i-gisaaea noids 25, 26 and 25 26, whenever one or electromagnet is energized to actuate the the other of said sets is energizcd by the spindle. operation of one or the other of the push 2.
