SPECIFICATION formingpart of Letters Patent No. 662,187, dated November 20, 1900.

Application filed May 9, 1900. Serial No. 16,098. (No model- To call whom it ntcty concern.-

Be it known that I, STEPHEN A. COPENHA- FER, a citizen of the United States, residing at York, in the county of York and State of Pennsylvania, haveinvented certain new and useful Improvements in Automatic Hanging- Up Machines for Paper or other Fabrics, of

which the following is a specification.

This invention relates to machines for drying paper or fabric in continuous strips, and more particularly to machines for drying wall-paper as it comes from the printing-machines. It has been customary to hang the paper in a series of loops upon laths'which are moved step by step on elevated ways or supports carrying the loops of paper over steampipes or other means for supplying heated air. These laths have generally been rectangular and are fragile, and a great deal of expense and delay has been incurred by the breakage of laths and stoppage of machines. The present invention permits the use of round sticks in place of the laths, and the sticks are so handled that breakage is practically impossible. A great saving in paper and sticks is thereby efiected and much valuable time of the machines heretofore lost is saved.

The invention will now be particularly described, reference being had to the accompanying drawings, in which Figures 1 and 1 constitute together a side view of a complete machine embodying my invention, parts being broken away to show some of theinterior mechanism. Fig. 2 is an end View of the stick-feeding machine. Fig. 3 is a side view of the same. Fig. 4 is a central sectional view on the line 4 4 of Fig. 3. Fig. 4 is a section of the support and guide for the upper member of the carrying-chain shown in Fig. 4, and Fig. 5 is a perspective view illustrating the devices for lifting the sticks from the chain.

Referring first to Figs. 1 and 1*, P indicates the strip or web of paper which travels in the direction of the arrows as it comes from the printing machinery. The paper is caught in loops upon sticks S and carried, by means of chains, slowly over steam-pipes or other apparatus suitable for driving off the moisture.

The present invention relates to means for handling the sticks, which will now be described, beginning with the hopper or box in which a number of sticks are stored.

The stick-feeding machine, which is particularly shown in Figs. 2, 3, and 4, comprises the following parts mounted on asuitable frame 10: At the upper part of the frame is supported a hopper 1], having two movable bottom sections 12, which are hinged near their outer edges to rods 13, supported on suitable arms or brackets 14. The bottom sections 12 are rocked alternately upon their pivots 13, said sections when in their lowest position forming a continuation of the inclined bottom 15 of the hopper.

The sticks I preferably use are round in cross-section and constructed of some suitable hard wood. These sticks are kept parallel in the hopper and rode back and forth by the movable bottom sections over the cen- 7o tral opening between the sections and one by one the ends of the sticks drop in between guides 16 in the end frame of the machine, the sticks forming a parallel series between said guides, as shown clearly in Fig. 4. The bottom sections may be oscillated by any suitable mechanism. As shown, they are connected by links 17 to straps surrounding eccentrics 18 upon a rotating shaft 19, Fig. 2.

Below the guides 16 are oscillating arms 20, which, as shown, are loosely mounted on the shaft 19. The arms 20 are rocked by means of connecting-rods 21, which are reciprocated by links 22 on arotating crank-shaft 23. On the ends of the arms 20 are circular segments 24, which support the sticks in the guides 16 while one of the sticks is being fed to the lower stick-carrier chain. Pivoted on the rear ends of the segments 24 at points 25 are a pair of delivery-levers 26. Each of 0 these levers has at its upper end a shorter finger 27 and a longer finger 28, said fingers being adapted to receive between them the lowest stick in the guides 16. The lower ends of the delivery-levers 26 are provided 5 with slots 29, through which pass stationary pivot-pins 30. These pins are carried in slots in the ends of arms or brackets 31, which are adjust-ably bolted to the frame 10, Fig. 3, the said arm being provided with slots 32, which permit of vertical adjustment.

The sticks are delivered one at a time at 1 properlyupon the horizontal carrier-chains regular intervals to the lower carrier-chains 34, which pass around the sprocket-wheels 33 at the delivery end of the apparatus and the chain-wheels 35 at the receiving end. These chains carry brackets or arms 36 at regular intervals, and the movements of the stick-feed devices are timed to deliver a stick in front of each pair of arms as they rise to the upper side of the wheels 33, as shown particularly in Fig. 1. The returning lower member of the chain 34 is supported upon a series of loosely-mou nted sprocket-wheels 37, each of which has a gap 38 in its periphery in place of one ofthe teeth to permit the brackets 36 to pass.

The operation of the device as thus far described is as follows: The sticks are dropped into the hopper continuously by devices to be described hereinafter. The bottom sections 12 are worked up and down and the sticks rolled or fed into the vertical guides 16, which guides engage only the ends of the sticks. When the arms 20 are in their rearward po sition, as shown in Fig. 4, the lowermost stick in the guides drops below the ends of I the guides in between the fingers of the carrier-levers 26. The arms 20 are then rocked forward, carrying the lowest stick downward to the sprocket-wheels 33, the circular segments 24 in the meantime supporting the remaining sticks in the guides. The.fixed pivot 30 is so adjusted as to bring the fingers 28 into a position su bstantially tangential to the sprocket-wheels 33, and while said fingers are in their lowest position a pair of brackets 36 on the carrier-chains 34 take the stick from the fingers and carry it along to the other end of the apparatus. The upper members of the carrier-chains 34 rest upon continuous supporting planks or plates 39, which are preferably grooved to guide the chains. The sticks are prevented from moving endwise while being transported by flanges 40. Provision is made for adjusting the ends of the chain-supports 39, so that they may be adapted to difierent sizes of sprocket-wheels 33. As shown, the ends of the supports are carried by bolts 41, which are adjustable in slots 42 in fixed brackets 43. At the receiving end of the machine the sticks are raised from the chain 34 by inclined or Wedge-shaped plates 44, which bring them up into the paths of brackets 45 on an inclined chain 46. Gravity-pawls 47 prevent the sticks from dropping back on the chains 34, and as the brackets 45 engage the sticks the latter are carried around the lower sprocket-wheels 48, between the chains 46 and fixed curved guides 49. As the sticks travel up on the upper member of the chain 46 the web of paper is delivered to them in loops, as shown in Fig. 1 the paper being 1 chains.

they are carried down to the hopper 11.

brought to this point by any suitable means, such as the conveyer-belt 50. The conveyorchains 46 travel rapidly and the velocity imparted to the sticks would cause them to be thrown from the chains as they pass around the upper sprocket-wheels and not landed 51 if means were not provided to restrain the sticks from improper movement. To accomplish this, I provide just above the sprockets 52 loosely-mounted devices, which serve to keep the sticks on their chains without impeding their proper movement with said As shown, these devices consist of a pair of toothed wheels 53, carried by pivoted rocker-arms 54, the lower teeth of said wheels resting upon or being close to the chains 46 and 51. The sticks strike the lower teeth of the wheel 53, and their velocity is checked from the high speed of the chains 46 to the lower speed of the chains 51, the sticks at the same time being kept in contact with the chains and at right angles thereto. These loosely-mounted wheels or checking devices I have found very valuable and, in fact, essential to the use of round sticks in this class of machinery. From the chains 51 the sticks carrying the loops of paper are delivered to chains 55, and when they reach the delivery ends ofthe chains 55 they are pushed along on fixed guides 56. The paper is pulled off of the sticks on the guides 56 byany suitable mechanism, and the'sticks are delivered to a pair of notched or toothed wheels 57, by which A pair of arms 58, carried by the hopper, raise the sticks from the notches 59 in the wheels 57 and deliver them into the hopper.

It will be evident that various changes in the mechanical details of the machinery heretofore described may be eifected without departing from the spirit and scope of my invention. For instance, it is to be understood that various kinds of belts may be substituted for the chains illustrated and described.

Equivalent devices may also be substituted for said sticks below the hopper, two movable sections in the bottom of the hopper adjacent to the guides, means for moving said sections to direct the sticks into the guides, and means for delivering the sticks successively from the guides to thecarryin g devices.
