FEED GAUGE.

Application filed September 12, 1924. Serial No. 737,305.

This invention relates to a feed gauge and is more particularly adapted for use in `connection With perforating machines.

One of the objectsof the present invention is to provide an improved feed gauge, which is simple in construction and efficient in operation.

A further object of the invention isto provide an adjustable feed gauge which can be quickly and easily changed to meet various reqnirements.

A still further object of the invention is to provide a device of the class described, which will operate with the least possible effort on the part of the operator.

These and other objects are accomplished by providing a construction and arrangement of the variousparts inthe manner hereinafter described, and particularly pointed out in the appended claims.

Referring to the drawings- Fig. 1 is a top plan view of my `improved feed-gauge;

Fig. 2 is a cross sectional View taken on the lines 2-2 of Fig. 1;

Fig. 3 is an enlarged fragmentary cross sectional view taken on the lines 3--3 of Fig. 1.

Fig. 4 is an enlarged fragmentary top plan view of the guiding member or carriage; and

Fig. 5 is a cross sectional and side elevational view of the construction shown in Fig. Li.

The invention, in the present instance, `is directed to a feed gauge, which is particularly adapted for use in connection with the intermittent feedingof pre-determined lengths of paper or the like to a machine such, for instance, as a perforating machine, so that the paper so :fed is perforated at predetermined :inter tals.

The present invention is"particularly useful in connection with the perforation of bank checks and the like where the checks are a1.'- ranged o n large sheets of paper, and a rc perforated from each other sothat each check may be readily torn from the remaining checks onv the sheet.

In carrying out the present invention, I have shown my improved feed gauge being mounted on a base 10, `which is preferably made of Wood for the purpose of lightness, but which might Well be made of any material, such, for instance.` as aluminum or other metals. "The base is substantially square in outline7 and is provided, on one side thereof, with a recess 11 to accommodate the operator. Positioned on the opposite sides of the base l() adjacent the outer edges thereof and extending longitudinally With respect thereto are flat metal strips 12, which are secured thereto by Wood screws 13. Extending along the metal strips 12 'and secured thereto by means of rivets 14 and slightly overhanging the inner edges thereof are longitudinal tracks 15.

- Positioned on the opposite sides of the feed gauge and secured to the metal strips 12 by means of brackets 16- are two longitudinally extending bars 17. These bars 17 are square in cross-section, and are detachably secured in horizontally disposed apertures 18 in the brackets 16 by means of set screws 19. Mounted on the square bars 17 are a plurality of stops 20, which are adapted to be adjusted `longitudinally ofthe bar. These stops are adapted to be locked in predetermined positions of adjustmentby set screws 21, which extend through these stops in a manner to clamp the stops to the bar 17.

Mounted on the tracks by means of rollers is a carriage or guiding member 22. The carriage or guiding member comprises a transversely extending sheet supporting` member 23 having its forward edge beveled, as shown at 24. The carriage is mounted on the tracks in such a manner so that the sheet supporting member is slightly positioned above the base 10 in order to permit the same to be freely moved back and forth in the tracks Without engaging the same. The sheet supporting member 23 has secured on the onter ends thereof by means of screws (not shown) roller brackets 25. The outer ends of the roller brackets 25 are provided with horizontally rotating rollers 26, which are adapted `to engage the inner edges of the tracks 15.

These rollers 26 are spaced a consiiilerable distance apart so as to properly guide the carriage 1n a line substantially parallel to the track. One of the roller brackets '25 is provided With two vertically rotatable rollers 27,

which are positionedadjacent the rollers 26, andare adapted to engage the uppersurface of oneof the tracks`15, While the other roller brackets 25 is provided with a single` vertically rotatable roller 28, which is positioned adjacent the forward roller 26, and adapted to engage the npp'er surfaceof the other track 15.

The object of providing the two rollers 27 on one side thereof,` and theA singleroller 28 on the other side thereof, is to permit the carriage to operate in the event the base, which in the present invention is made of wood.v warps. Infother words, in the event the base l0 should warp and if two rollers were provided on the opposite sides thereof, the device would become inoperative, because the carriage would bind by reason of this warping.

The roller brackets are provided, on the outer sides thereof, with sockets 29, which are adapted to receive and have reciprocally mounted therein pawls 30. The pawls 3() are normally pressed outwardly by extension springs 3l engaging shoulder 3&3 of the pawl 3() at one end thereof, and engaging the base of the sockets 29 at the other end thereof. The pawls 30 are provided with inwardly projecting stem portions 33, which have vertical apertures, as shown at 3l. The pawls 3() are provided with bevelled portions, shown at 35, which are adapted to engage bevelled portions 3G of the stops 2() when the carriage is moved forwardly, and when the farriage is moved rearwardly vthe rearward faces 37 of the pavvls 30 are adapted to engage the forward faces 38 of the stops 20. The pawls `are actuated or withdrawn from their outermost position by hand ope ating levers 39', which are mounted on cranks 39 pivoted by means of a shoulder screw 4l to a reinforcing bar 4t2, which, in turn, is secured to the sheet supporting` member 23 in any well known manner.

In order to properly position the paper so that the edges thereof will be parallel with the track or the movement of the carriage, I

have provided an aligning bar 4l which is adjustly secured to the member 23 by means of screws 42. The levers 39 are each connected to the pawls 30 by means of a connecting' rod 43. In order to prevent my carriage 22 from being' entirely disengaged from the track in its movement, I have provided stops 44 secured to the opposite ends of the strips 12, as clearly shown in Figs. 1 and 2.

In the operation of the above described device, it will, of course, be understood that the stops 2() are positioned at desired intervals, or at the intervals at which it is desired to perforate the paper, and secured in these positions by set screws or bolts 2l. lhen this is done the paper to be perforated is positioned on the sheet or paper carrying` member 23, with the edges thereof enpaging, the front edges of the bar ill and held thereon by the hand of the operator. lVhen in this position the carriage is held so that the faces 37 of the pawls 3() engage the faces 38 of the first stops 20. Then in this position the perforating machine is then actuated by the control lever of the operator. After the first perforations havebeen made in the paper the carriage is pushed forwardly 'by the operator past the next forward adjacent stops. In the passing of thenext stops forwardly it will be noted that the beveled surfaces of the pawls 30 engage the beveled surfaces 36 of the stops 2O and cause these pawls to snap after passing these stops. As soon as the pawls snap, or are forced to their outermost position, the carriage is then drawn backwardly so that the faces 87 of the pawls 30 engage the for yard faces 38 of the stops just previously passed, and then the perfor-ating' machine is again thrown into operation to perforate the next set of pcrforations.

This operation is continued until the sheets have been completely perforated, and then the carriage may be withdrawn lto its rearmost position by actuating` the levers 39 inwardly, an d thereby drawing' the pawls 30 inwardly against the tension of their extension springs 3l, thereby permittingl the carriage 22 to be withdrawn to its rearmost position,

From the above description it will, of course, be understood that additional stops 20 may be added if necessary, and that these stops may be positioned along their respective bars l'i' in such a manner that any interval between the perforations may be had.

From the above it will be noted that I have provided a very simple and etlicient feed gauge, and one which may be adjusted to meet various requirements.

It will also be noted that I have provided a device which will insure accurate and parallel perforations of the sheets of paper placed on the carriage.

And furthermore, I have provided a device which will not bind, but, on the contrary, will operate with great facility and ease.

While in the above specification I have described one embodiment which my invention may assume in practice, it will, of course. be understood that the same is capable of moditication, and that modification may be employed without departing from the spirit and scope of my invention as expressed in the following' claims.

What I claim as my invention and desire to secure by Letters Patent is:
