UNITED STATES JOSEPH R. BLAINE, OF OAK PARK, ILLINOIS, ASSIGNOR TO MIEELE PRINTING PEEES & MANUFACTURING COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OE ILLI- PRINTING-PRESS FEEDER MEANS.

Application filed llay.3, 1924. Serial No. 710,756.

This invention relates to a printing press and more particularly to sheet separator mechanism and control means therefor.

The invention is illustrated in connection with what is known as a fiat bed press in which the bed reciprocates in a horizontal plane and cooperates with an impression cylinder, the feed pile being carried in a frame which is separably connected to the main frame of the press. The feeder pile frame is separably connected from the main frame and movable away from said main frame for the purpose of giving access to the bed of the press, particularly to facilitate the operation of make ready.

The feeder pile frame is provided with front guide means for the sheet material in the pile and during the operation of the sheet .separators the latter are caused to move downwardly behind said front guide means. If, when the separators are down the feeder pile frame were moved rearwardly for the purpose of separating it from the main frame, the front guide means would pass into engagement with the separators and damage same.

Accordingly, one object of the present invention is to control the position of the separators more particularly during the movement of the feeder pile frame away from and toward the main frame of the. press to prevent any damage being done to said separators. v

Another object of the invention is to provide separator mechanism and control means therefor adapted to meet the various requirements under service conditions.

These and other objects are accomplished by means of the arrangement disclosed on the accompanying sheets of drawings, in which- Figure 1 is a fragmentary side elevation .of a printing press embodying my invention and showing the feeder pile frame in its normal operative. association with respect to the main frame of the press;

Figure 2 is a similar side elevation of the press, but showing the feeder pile frame moved out of operative association with the main frame of the press for the purpose of facilitating the make ready operation;

Figure 3 is a fragmentary top plan view, parts being in section, and taken in the plane of line 3-3 of Figure 1, showing various cooperative elements including the separator parts and control mechanism therefor; and

Figure 4 is a detail fragmentary side elevation of the parts shown in Figure 3.

The various novel features of the invention will be apparent from the following description and drawings and will be particularly pointed out in the appended claims.

Referring to the fi'gures'of the drawings,

it will be noted that the invention is illus trated in connection with aprinting press including a main frame 10, in which an impression cylinder 11 is rotatably mounted,-

which impression cylinder cooperates with type or plates carried on the horizontal re- .ciprocatory bed (not shown). A feeder pile frame 12 may bemoved away from and'toward the main press frame 10 by any suit able mechanism, the feeder pile frame normally being locked to the main frame by any suitable mechanism including one or more hooks 13, preferably one at each side of the press, which are adapted to latch.over tongues or projections 14 carried on the-main frame 10. Preparator to moving the'feeder pile frame away from the main frame it is merely necessary to depress a hand lefVerzlS which is connected to a rock shaftld, to which the hook or hooks 13 are secured, whereupon the latter are lifted out ofen gagement with the projections 14.

mix

Movably mounted in the feeder pile frame is a pile of sheet material 17 which is suitably supported upon atable 18 which may be raised step by step in any suitable manner as the sheet material is fed therefrom preparatory to receiving an impression. The pile of sheet material is guided in its vertical movement by any suitably supported front guide means 19 which, in this instance, comprises a plurality of vertically extending bars, only one of which is shown. The sheet material is separated sheet by sheet from the pile and raised slightly therefrom by a plurality of separators 20 each mounted upon the lower end of one of a plurality of rods 21 slidably and guidedly carried in a barrel member 22 having a shank 23 horizontally adjustably mounted in a bracket 24 carried and supported by supports or shafts 25 and 26. It is found that sheet material of different weights, quality, etc, are separated best under different conditions, including the relative position of the separators with res t to the front edge of the sheet. .Accor ingly, the horizontal adjustment of the separators accomplishes this purpose. When the separators are adjusted to the (proper positions under the particular con itions imposed, each is secured in its adjusted position by any suitable means, such as a set screw 27.

Referring further to the slidably mounted rods 21, it will be noted that the u per portion of each of said rods passes t rough a forked portion 28 of an associated arm 29, each of which arms 29 is secured to a cross shaft 26. The upper end of each rod is provided with rollers 31, which ride upon the upper surface of the forked portion 28 of each arm 29 to facilitate relative movement which may be occasioned between said rods 21 and the arms 29 during an up and down movement of the separators. Normally these separators are reciprocated vertically b a rocking of shaft 26 which 18 automatica y rocked through mechanism including an arm 32 secured to one end of the shaft, said arm in turn being pivotally connected at 33 to any suitable operating rod 34.

As mentioned hereinabove, during the operation of the separators 20, the latter are caused to move behind the front sheet guide means 19 and below and within the horizontal path of movement of the top of said guide means when the latter is moved rearwardly with the feeder pile frame 12 away from the main frame 10. It is apparent that if the se arators 20 are permitted to remain in suc position as just described, during the rearward movement of the feeder pile frame 12, that the guide means 19 will pass into engagement with said separators 20 and probably cause damage to the latter. In order to prevent damage being done to said separators and to insure safety of said separators, means is provided for automatically raising said separators 20 to a safety position out of the path of rearward horizontal movement of said front guide means.

The means for thus raising the separators 2O out-of the path of movement of said front guide means 19 includes an arm 35 secured to the shaft 26, whicharm is adapted to be rocked upwardly for causing the shaft 26 to rotate a given amount in a counterclockwise direction, as viewed in Figures 1, 2 and 4, for liftingthe separators through the arms 29, which are also secured to the shaft 26.

The arm 35 is actuated by a cam 36 formed on one arm of a bell crank lever 37, the other arm of which is pivotally connected to a rod 38 in turn pivotally connected to the lever 15 which controls the unlocking movement of the latch or latches 13 from the associated locking projections 14. Accordingly, when the lever 15 is depressed for raising the latches 13 out of locking association with the projections 14 preparatory to moving the feeder pile frame 12 away from the main frame 10, the separators 20, through the connections hereinabove described, automatically are raised out of the path of horizontal movement of the front (pile guide means 19, which is mounted on an moves with the feeder pile frame 12. After the separators 20 are thus raised to a safe position throu h the arm 35 it becomes essential that sai separators should be maintained in said elevated position. This is done by a spring pressed latch 39 which asses under the arm 35 for holding the atter and, accordingly, the separators 20 in elevated position.

However, it is conceivable that the latch 39 might possibly become detached from the arm 35, as for example, if it is desired to adjust the horizontal positions of the separators 20. In such event it becomes important to again raise the separators 20 out of the path of horizontal movement of the front pile guide means 19 before said guide means with the feeder pile frame 12 is moved into its normal position with respect to the main frame 10. To accom lish this result, a cam 40 is provided which is secured to the feeder pile frame 12. This cam cooperates with a roller 41 mounted in the rear end of an arm 42 also secured to the shaft 26. Accordingly, as viewed in Figures 1 and 2, it will be apparent that as the feeder pile frame 12 is moved from its position away from the main frame, as shown in Figure 2, to its normal position in operative association withthe main frame 10 of the press, as shown in Figure 1, the roller 41 will ride on the cam 40 in a manner to depress the arm 42 and cause the separators 20 to be raised out of the path of horizontal movement of the front uide means 19.

It will be noted that t e shaft 26 is alwa s rotated a small amount in a counterclock wise direction, as viewed in the figures of the drawing, for raising the separators 20 whether said separators 20 are raised automatically through the arm 32 during the normal operation of the press, or automatically'as t e feeder pile frame 12 is unlocked from the main frame 10, or automatically when said feeder pile frame 12 is moved from the position shown in Figure 2, into its position of operative association with the main frame shown in Figure 1.
