Application led April 27,1917, Serial No. 164,942. Renewed January 1 7, 1921. Serial No. 437,374.

To all whom. it may concewb:

Be it known that I, JOSEPH R. BLAINE, a

I citizen of the United States, and resident of Oak Park, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in a Reloading Feeder, of which the following is a specification.

My invention relates to printing presses,

and particularly to means for feeding and reloading` a pile of sheets.

An object in the resent invention is to provide means where y the usual delays incident tothe reloading of a. feed pile may be avoided. To this end I -have provided a plurality of endless chains together with means for actuating the same in unison. These chains depend in a long loop at a point near the corners vof the table. Clutch members are provided onthe table adj acent the chains the clutches being so constructed as to enableengagement with the chains at drawings, wherein,

nection with the table for adjusting the pile thereon in order that it 4may be accuratelyI positioned as required when automatic fee ing mechanism 1s employed.

The inventionwill be'more readily understood by reference to the accompanying A Figure 1, 1s a side elevation of pile feeding means constructed in accordance with my 1n' vention Fig. 2 1s a view taken at right langles toI that of Fig. 1, and showing one corner only j of the arrangement;

Fig. 3 is an enlarged side elevation of the chain clutch;

Fig. 4 is a sectional view on `the line 4 4 of F1g. 3.; f

Fig. 5 is an enlarged view, partly in section, showing the means employed for adjusting the table and,

, .Fig 6 is a view taken at'right angles to that of Fig. 5.

In the drawings it will be seen that I provide a plurality of standards 10, on the lhaving a upper ends .of which are supported the paper I feeding means indicated diagrammatically at 11, 12. The standards 10, may be in the form' of large tubes or cylinders and serve to support arms 13. The arms are adapted for oscillation within the limits defined by the stops 14. By this means the arms may be swung out of the position shown. in Fig. 1 to permit of the entrance of a truck carrying a new ile. The arms 13,- upon collals 15, which carry the stops 14, the collars being adapted. to be secured at different in ts in the height of the standards 10. nasmuch as the weight., imposed on the arms when a full pile is to be supported thereby is great, I have provided jacks 1G, Y

1 which directly transmit the load to the floor or a similar support. These jacksmay be merely in the form of a threaded standard engaging the outer ends of the arms. The

pile of paper indicated at 17, rests directly upona table'18, which is in turn supported by the I-beams 19. In the channels of the I-beams at the ends thereof are mounted the clutch members shown in Figs. 3 and 4. These members comprise a body portion 20, having a slot 21, and 'an end member 22,`

chain-shaped side opening 23. T he opening 23, is intersected by downwardly projecting lugs 24.` The arrangement of the recesses 1s such that a chain readily engages` the same but cannot be disengaged without. first lifting the clutch member. This ob-v viates the possibility of accidental disengagement of the lifting element and the pile table.

The lifting elements are in the form of endless chain c onveyers 2 5, one of which is provided at each corner of the table and which depend in the'form of a long loop. The chains at their upper ends pass around suitable sprockets 26, mountedA on a long v shaft 27, for movement in unison in the same direction7 of the corresponding portions of every chain. Manual or power means may be employed for actuating the shaft, no such means being here shown. -v

Itis sometimes necessary that the table be adjusted relatively to the supporting beams 19, and as the weight is great, I provlde vscrew, means such as shown in Figsf and 6,

for accomplishing the'desired result. The means-comprise a block 28, having tapered lips'29, on the under surface thereof, adapted to fit over the flanges 30, of the beam.

-dowel -pin,3 1, is carried by the block at a point near the rear edge of the block; .that is, at the point where there is the greatest space between the lips 29 and the body of the block.v This pin is` adapted to engagev one of the recesses 32, in thev topv of the beam.y

.4- Abolt 33, passes through the block 'and en- .gages the side of the table 18'. To engage or disengage the adjusting means from the beam it is necessary only to rock the saine on its-front edge. This will disengage the dowel and permit the block to be slid longitudinally of the beam. e

The advantages in this construction arise from the fact that a pile may be readily attached-to the lifting chains and be elevated as' required' until the pile is nearly @enhausted. `Inthe' meantime a new pile'may be moved by a truck to a point directly beneath the first pile, whereupon the truck.

may be removed and the pile supported on the arms-13. lVhile in this position it willI be positioned accurately by the 4'means just described. During that vtime the clutch members 20, will be in a retracted position' as -shown inthe lower portion of Fig. 2; that is, where thechain is not engaged therewith. This is accomplished by sliding the clutch member longitudinally of the beam. It will be noted thatl the bolt-34 serves merely to hold the parts in proper relation, no clamping action being necessary. When the upper pile is exhausted the table is disengaged by disengaging the clutch members whereupon the chain iscaused to engage the clutch members .of the lower table .and the operation ofv the printing press. may continue without unnecessary delay.

strued with that understanding;

I 1. A lifting conveyer for pile tables, comi prising in combination, a plurality of chains, and clutches carried by the table, said clutches having open sidedf'chainshaped recesses and downwardlyprojecting lugsi for en aging any link'of'said chain,

whereby` ac ain cannot be separated there from without first raising the clutch member, substantially as described.

2. Pile feeding means, comprising in combination, a plurality ofstandards, swinging arms supported on 'the standards near-the lo\Wer ends thereof, and means for lifting a pile between the standards, a second pile being adapted to be supported on said arms While4 said first pile is being lifted and means carried by said'arms for 'serving as additional supports therefor, substantially as described.l

3.` Pile feeding means, comprising in combination, a plurality of standards, swinging arms supported on the standards near the Y' lower ends thereof, a plurality of endless lifting elements depending between the standards, a table adapted to be engagedV by said elements, and a second table adapted tol be supported on said arms and to be engaged by said elements and means carried by said arms for serving as additional supports therefor, substantially as described.

4. Pile' feeding means, comprising in combination, a plurality'of standards, swinging arms supported on the standards and adapted to be swung into and out of supporting position', and a jack on each of said arms for transmitting weightdireetly to a support at points other than at said standards, substan- 'l tially as described.

5. A feeding means for printingpresses, in combination, a plurality of endless conveyers, 1 means for causing -the movement thereof in unison in the same direction, a pile table, clutches carried by the table and constructed to operatively engage the con` veyers at any' point in the length thereof, and tobe disengaged therefrom when said -conveyers1 reach .the end of travel thereof in one direction, a second pile table arranged t0 engage said conveyers while saidrst l table is in engagementtherewith and at a pomt below said first table, means for supporting said table in position to be engaged by said conveyers, 'and means .for adjustably justment means eing carried by the table.

and arranged to maintain said pile` in ad? justed position .during the movement of the table by the conveyers.`
