To positively insure proper register, I provide a side registering device, which is shown as consisting of a lug or post 20, extending from a plate 21, adjustably secured to a cross-rod 22, extended transversely of and preferably between the flights of the belts. A lever 23, connected at one end to this crossrod, is engaged at its other end by acam 24, the action of which is to move the luginward, so as to engage the edge ofthe stock and shift the latter laterally to proper register, the forward movement being given thereto by the belt.

In practice the stock, such as envelopblanks, is fed onto the endless belts by any suitable means or by hand, one sheet or blank at a time being carried forward into engagement with the forward stops. 'If the engagement is with but one stop,'or even though' there be but an imperfect engagement with either, the stock will be held against the belts by one or both of the balls 16, while its further conveying to proper register is accomplished. The side registering device acts on the stock if it be within the range of travel of lug 20. As the'stock is properly positioned over the plate 3 the spring-fingers 4 are lowered to retain it untilgrasped by the gripper, whereupon the fingers will be raised and the stops 7 lowered out of the Way.

The advantages of my invention are apparent to those skilled in the art. The quick and accurate register of the blanks or other stock is rendered possible by the universallymovable bearings or contacts, which allow the stock to be moved transversely as well as forwardly and'in both directions at the same time, oifering no obstacle to its travel to proper register, no matter in which direction it may be moved. Independently of the side registering device the stock will, if the blanks be all of exactly the same size, readily travel in a proper register by being held down to the belts by the balls. The curvature of the inner ends of the forward stops insures the proper engagement of envelopblanks with such stops, even Without the aid or cooperation of the side registering device.

I claim as my invention 1. An envelop-blankeregistering device comprising a series of endless belts, forward stops having inner opposite rounded edges,

for the purpose stated, and means for hold- Y ing the blanks to the belts While being moved to register with said stops, as set forth.

2. An envelop-blank-registering device, comprising a series of endless belts, forward stops having inner opposite rounded edges, for the purpose stated, and contacts for bolding the blanks to the belts having each a loosely-mounted ball, said contacts being located near said stops and designed to engage the stock while it is being moved to register, as set forth.

3. The combination with the conveyer, forward stops having inner opposite rounded edges, and means for retracting the steps, of means for bearing down on the stock, contacts having loosely-mounted balls for holding the stock to the conveyer while it is being moved to register, a side registering de-- vice, and means for operating the same, substantially as set forth.

4. The combination with the conveyer, the forward stops having rounded edges, and means for retracting the stops, of contacts having loosely-mounted balls for holding the stock to the conveyer while it is being moved to register, a transversely movable rod, means for actuating the same, a plate having an upright lug, and means for adjustably holding said plate to said rod, substantially as set forth.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

CHARLES GRANT HARRIS.
