Application filed April 14, 1921, Serial T aZZ whom 2'2, may concern:

Be it'known that I, Emmi: H. SMITH, a subject of the King of Great Britain, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have in vented new and useful Improvements in Sheetdtegister Devices, of which "the following is a specification.

My invention relates to sheet registering devices, particularly to devices for registering the sheet sidewise, and especially pertains to devices for bringing sheets into correct side registered position on the feed board of a cylinder printingipress.

An important object of my invention lies in the provision of a side registering device the employment of which will'not necessitate any cutting into, or other modification of, the feed board of the press. It is another object of my invention to provide a side registering device which will be especially certain in its operation of bringing the sheet accurately into position against a side register gauge. A further object of my invention is to provide a side register device of a character economical to produce and install, simple to understand and easy to adjust and maintain. Other objects will appear from the following specification taken with the claims forming part thereof.

I have shown in the accompanying drawings, and described in the following specification, one form of device in which my invention may be embodied. It is to be understood, however, that the invention may be embodied in other forms, with-out exceeding the scope thereof, as defined in the appended claims.

No. 461,307. Renewed August 4, 1924,

herein specifically described is arranged for use in connection with the sheet feeding mechanism disclosed in my copending application Se. No. 460,243 filed April 11,1921; It includes a pair ofv bearing brackets 1O, secured to'rails,"11, 11. such as are 'disclosed inmy said copending application, which rails are secured to a press feed board 12, having, at its front part, a feed platelB. Secured between the brackets 10 isa rod 1-1, and slidably mounted a shaft The shaft 15 is provided, at its end, with a removable collar 16 having extending therefrompins 17 which are'enr braced by a fork 18 formingpart of a double bell-cranklemr 19 which is pivotally associatedwith the feed board. A link 20, connected withone arm, 21, of thebell-crank lever. and given a shortreciprocating move-' ment by an appropriate device, such as a cam, crank or the like, effects a rocking movement of the bell-crank lever 19, and thus a lengthwise sliding movement of the shaft 15 in its bearings'in the brackets 10. The link 20 may be connected to the other arm, 22, of the double bell-crank lever 19. if desired, so as to reverse the direction'of sliding movement of the shaft 15.

Secured to the rodyl l, and having a slide the shaft 15, is a collar 23 having extending downwardly therefrom a pair of lugs 2-1 between which is pivoted a sleeve 25. A threaded stem 26 passes through the sleeve and carries, at its end, a side-gauge plate 27, a spring 28 being disposed between the collar 25 and'the sleeve 25, so

"as to cause the-bottom of the side-gauge 27 to press firmly on the feed plate 13, thus providing a sure abutment for the edge of the sheet and admitting no possibility of the sheet entering beneath the gauge. Thumb nuts 28 on the stem 26, and engaging-against each vend of the sleeve 25, permit ofa fine adjustment of the position of the side-gauge 2?. Coarse adjustment is made by loosening cures the collar 23 in position, and sliding the collar to the desired position on the rod 14. The side-gauge 27 has secured thereto a horizontal plate 29, having an upwardly curved rear end 30, which plate insures that the sheet being fed forward shall remain close to the feed-plate, and not curl away the set screw which sei in said brackets is 28, the side gauge 27 therefrom at the part near the side-gauge. The slde-gauge 27 is, further, formed with a slot 31 through which can pass the pneumatlc registering foot to be described below.

Mounted on the rod 14 is a collar 32 provided with friction pins 33 (Fig. 4), formed of fibre or the like, which are pressed against the rod 14 by springs 34, the pressure of which can be adjusted by means of screws35. Thus the collar 32 can slide on the rod 14 if pressure is applied, but will normally be held against such sliding by the friction pins 33. At its end remote from the pins 33, the collar 32 is formed with vertical flat sides 36, and has pivoted thereto, .by means of pins 37, the yoke 38 of the pneumatic registering foot. From the yoke 38 extends downwardly and laterally a leg 39 terminating in a foot 40, having in its underside, close to the end, a suction orifice 41 which connects, through a suitable channel with a boss 42 on which is mounted a hose 43 leading to a suitable source of vacuum. Secured to the slide shaft 15 so as to be adjustable thereon, is a saddle 44 having downward extensions 45 which embrace the yoke 38 between them. Studs 46 are threaded into the extensions 45 and are provided at their ends with reduced portions 47 which enter corresponding openings formed in the yoke 38. By adjusting the studs 46, the reduced portions 47 can be caused to make close sliding engagement, with their ends, against the sides of the collar 32,whereby the parts of the group are maintained in proper alignment. EX- tending downward from the collar 32 are a pair of lugs 48 and 49 carrying adjustable abutment screws 50 and 51, between the ends of which the yoke 38 of the pneumatic registering footis located, space being left between the ends of these screws, however, so as to permit movement of the yoke between them.

The operation of the device is as follows: By shifting the collar 23 on the rod 14, and afterwards by means of the thumb nuts is placed in the posi tion to which it is desired that the sheet be side-registered. The set screw of the saddle 44 being loosened, the saddle and the collar 32 are slid on their respective members until they reach such a position that the end of the foot 40 will just clear the sheet-engaging face of the side gauge 27 when the yoke 38 is engaging against the abutment screw 50, the bell-crank lever 19 being in the positionshown in Fig. 2. in practice, the set screw being loosened, the saddle 44-is manually pushed to the left until the foot 40 has passed completely through the slot 31, and is then pulled back to the right until the end of the foot 40 just clears the outside of the side gauge 27 (Fig. 1).

The parts will then be in their correct position, and the set screw is tightened. Prior to an operative movement, the parts, therefore, occupy a position such as is shown in Figs. 1 and 2. The beginning of the registering movement is caused by the link 20 pushing on the arm 21 of the bell-crank lever, thereby causing the shaft 15 to move longitudinally towards the left. The collar 32 being held by the friction pin 33 against movementon the rod 14, the first effect of the sliding movement of the shaft 15 will be the swinging upwardly of the register foot, the pins 47 causing the yoke 38 to rock on its pivots 37 until the yoke engages the front abutment screw 51. Upon the yoke engaging the front abutment screw 51, it can rock no further, and continued sliding movement of the shaft 15 to the left causes the collar 32 to slide upon the rod 14, the pressure of the yoke 38 upon the abutment screw 51 overcoming the resistance offered the friction pins The movement of the shaft 15 to the left continues until the parts have reached a position such as that shown in full lines in Fig. 5, the foot 40 having passed through the slot 31 of the side-gauge 27 and being in position above a sheet 52 which, by that time, will have arrived in position beneath the plate 29 with its front part projecting over the feed plate 13 and its front edge engaging against the front gauges 53 of the press. Upon the return of the shaft 15 towards the right, effected by a pull being imparted to the link 20, the first effect will be a swinging down of the registering foot into the position shown in dotted lines in Fig. 5, in which it engages upon the sheet 52 and its yoke 38 engages against the abutment screw 50. The continued return movement of the shaft 15 will cause the collar 32 to slide on the rod 14 back to its original position, the pressure of the yoke 38 on the abutment screw 50 overcoming the resistance of the friction pins 33, the parts thus returning to the original position shown in Figs. 1

and 2. During the return movement of the register foot from thevposition shown in dotted lines in Fig. 5 to the posit-ion shown in Fig. 1, suction being applied thereto tirough the orifice 41, the sheet 52 will be attached to the foot 40 and move therewith until its edge strikes against the side gauge 27, by which gauge it is stopped from further movement, the foot thereafter simply sliding over the sheet until free therefrom. The sheet is thus brought into a proper reg istered position against the side-gauge 27.

An advantage of my improved register device lies in the fact that it is self-contained and entirely independent of the press feedboard, necessitating no mountings thereon nor any cutting or other modification thereof. The certainty and accuracy with which the device operates is anothersubstantial advantage, as also is the fact that the parts are simple and relatively few, and the fact that the whole device is economical of manufacture and easy of adjustment and -maintenance, even by a relatively unskilled operator. As described above, the device registers towards the right-hand side of the press. It is often desirable to register the sheets towards the left-hand side of the press, and, to allow of this, a second set of members, du plicate to those above described, may be provided at the other ends of the rod 1% and shaft 15, or those parts which are shown may be taken off the rod 1 and shaft and reversed as to the direction in which they point. When such duplicate or reversed'set is to be used, the direction of movement of the shaft 15 is reversed by connecting the link to the bell crank arm 22 instead of to the bell crank arm 21. It will be noted that all of the elements are made uniform from a common center so as to permitof the above described reversal or duplication for left and right hand register.
