LATERALLY-ADJUSTABLE TABLE FOR AUTOMATIC PAPER-SHEET FEEDEBS.

Application filed June 7,

provide an improved feed table or hopper which may be bodily adjusted across the machine, so that the side guides may be adjusted for the width of the sheet to be fed and then the entire mechanism adjusted properly with the rest of the machine.

Another object is to provide a laterally adjustable feed table or hopper for automatic feeders that will permit the running of the small stock near one edge of the feed table and the operator have easy access to the table from the side without the necessity of reaching over from the rear of the table;

A further object is to provide a locking means for securing the feed table or hopper in the required position.

A further object is to provide a simplified form of'construction which shall be rigid and yet of light weight and simple to manufacture.

Other objects of the invention will appear from the following detailed description.

The invention consists generally in various constructions and combinations, all as hereinafter described and particularly pointed out in the claims.

Inthe accompanying drawings, forming a part of this specification, 1 igure 1 is a plan View of an automatic folding box gluing machine with my invention applied thereto, showing the machine set up for a medium sized blank with the edges of the blank engaging suitable guides placed on the lefthand side of the feed table or feed hopper.

F igure 2 is a View similar to Figure 1 except that the machine is-set up for a narrower blank with the edges of the blank guided by setting the guides close to the left-hand side of the feed table and the feed table adjusted laterally to the right, so that the operator may stand on the side and easily supply the hopper with the small blanks without the great inconvenience of reaclnng over f om the back of the feed table to the feed wheels, a distance of about 32 inches.

1926. Serial No. 114,216.

' Figure 3 is a side view of the feeder lookmg from the drive pulley side of the machine.

Figure 4 is a section through the center of the feeder.

Figure 5 is a detail of the feeder showin the left side bracket and its manner 0% mounting, so that it will slide laterally on the uides.

Figure 6 is a rear view of the feeder with i the feed table or hopper removed, toshow the manner of mounting the supporting brackets for the feed table.

Figure 7 is a view similar to Figure 6, except that the brackets which support the feed table are shown at the limit of adjustment.

In the drawing, 2 represents a folding paper box gluing machine having the usual drive pulley 3, glue pot 4, delivery table 5, the lower feed drum 6,-having the usual carrier belts 7 and feed wheels 8, all mounted upon suitable shafts and driven in a suitable manner.

The feed wheels 8 are preferably mounted on a shaft 9 having hearings in brackets 10 and 11 on each side of the machine.

This shaft 9 is usually driven by the feed wheels through their frictional contact with the belt 7.

The brackets 10 and 11 are connected with each other by a shaft 12, having an extension 13, and a shaft 14, having an extension 15. (See Figures 6 and 7.)

The shaft 14 has akeyway 16 and supports the feed adjusting mechanism 17, each being secured in position after once heing set by the small set screw 18, which bears rigidly, and the two brackets are secured in position by the cap screw 23, which clamps the upper part of the bracket 21 on to the extended portion 13 of the shaft 12.

To the bracket 19 I pivot an arm 24 at the point 25, and to the bracket 21, I pivot an arm 26 at the point 27 i Suitable dogs 28 adapted to engage the teeth 29 in the brackets 19 and 21 are provided for holding the arms 2& and 26 in their adjusted positions.

The arms 24 and 26 are connected with each other by suitable boards 30, 31 and 32. The boards are spaced apart at points 33 and 34, so that suitable guides 35 may be placed on the upper side of the board and adjusted in the slots or spaces between the boards across the machine and clamped into position by the hand wheels 36 and 37.

In operating a machine equipped with my invention, the operator adjusts the machine as in my patent above referred to, but in-. stead of standing at the rear of the machine and reaching a distance of 32 inches to feed and keep the action of the feed wheel 8 under constant observation, as well as lifting the rear of the stack so that a new lift ma be fanned out and inserted under the stact from which the feed wheel 8 is feeding, he simply'adjusts the side guides to the lefthand side of the feed table and moves the table towards the right in line with the path' of the blank through the machine and stands ,on the left-hand side of the feed table, where he has easy access to the feed table, as well as immediate contact with the starting and stopping levers, the glue control levers, etc.,

which, except for my invention would require his passing around to the side of the machine. e

After setting the machine and moving the feed table to the right position, as shown for instance in Figure 2, the operator takes a wrench and tightens the screw 23, locking the feed table against lateral movement, and the angle or pitch of the feed table is then adjusted by the action of the ratchet dogs 28 in the notches 29 of the brackets .19 and 21.

It usually happens that after the machine is set up, the folding is inaccurate and the folder frames will have to be either opened or closed to a greater degree. Therefore the re-setting of both feed guides 35 would be necessary unless the machine was equipped with this invention.

If it is so equipped it is merely a question of loosening the cap screw 23 and tapping the feed table with the palm of the hand slightly in either direction to make it line up with the rest of the machine, so that the blank may enter the feed wheel at the pro er point for the glue flap to pass over the glue i wheel and the creases on the folding box to come in the right position for the folding mechanism.

I claim as my invention:

1. The combination with a frame and feed wheels mounted therein and means for driv ing said wheels, of brackets mounted for 2. In a machine of the class described, tilting arms mounted for lateral adjustment, a

feed table supported by said arms and comprising plates spaced apart to form gaps extending transversely of the table, upri ht guides mounted on said table and adjusta le transversely thereof and having means for securing them in'said gaps, the adjustment of said guides adapting said table for receiving and feeding blanks of different widths.

3. A machine of theclass described comprising a frame having transverse shafts therein, provided with lateral extensions, a bracket mounted on one of said shafts for slidable longitudinal adjustment, a second bracket mounted on the lateral extensions of said shafts and connected with said first named bracket for adjustment transversely of the machine, means for locking said brackets on said shafts, a feed table supported by said brackets for adjustment therewith transversel of the machine, and feed wheels mounte which said table is adjusted.
