PORATION OF NEW ERSEY.

PAPEB-DELIVEFIY.

Be it known that 1,.FRANK'B. DAVIDSON, a

citizen of the United States, residing at Marseilles, in thecounty of Lasalle and State of Illinois,hav"e invented certain new and useful Improvementsin Pa erDeliveries; and I e do hereby declare that t e following is afull',

clear, and exact description thereof, reference 'beinghad to the accompanying draw' ings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to anovel sheet-delivery device designed to receive sheets of paper, pasteboard, or the like from a machine in which the sheets are operated upon and to continuously deliver them u on recelving-surfaces located at difierent' eights or levels.

An instance of the use of improved delivery device is the application thereof to the discharge end of a machine for cutting sheets of determinate dimensions from a continuous web of aper or the like. It is often desired that s eets so discharged from such ma chine be delivered upon a truck by which the sheets in suitablepiles or bundles are carried away from the machine. During the continuous operation of the machine one truck cannot be'exchanged for another so quickly as to avoid a number of sheets being delivereduploln the floor, thereby requiring extia hand g. Adehvery device made in accordance w1th my mvention is mounted to swing ver-.

tically at its free end, and a shelf is provided above that part of the floor-space upon which the trucks are run to receive the sheets, so

that inthe interval between the time a filled truck is pulled awayand an empty truck moved in posltion to receive the sheets the free end of the swinging delivery device is swung upwardly to deliver the sheetsto said,

shelf, from which they may be removed in groups. Moreover, it is advantageous to gradually raise the outer end of the'delivery device as the ile of sheets on the trucks increases in heig t, thereby properly delivering the sheets to the top of said plle.

The invention consists'in the matters here-- inafter set forth, and .more particularly point- 1 ed out in the appended claims.

tionof the delivery device made in accordance with my invention, illustrating'also the machine in connection with which it is used and a truck upon which the sheets are deliv-.. ered. Fig. 2 is a plan view of the parts shown in Fig.1 Fig. ,3 is a transverse section taken on line 3 3 of Fig. 2. i -As shown in'the'drawings, A designates as a whole the dischar e end of a suitable sheetpaper-working mac 'ne from which sheets of aper are continuously discharged, and B,

' ig. 1, designates as a whole my improved sheet-delivery device. I

C designates a movable truck or cariupon which the sheets are delivered one by one and by which the bundles of sheetsare removed 1 from time to time.

The sheets are discharged from the machine shown between upper and lower sets of belts or tapes E and respectively. The belts or'tapes of the lower set F are trained at the end of the machine about a rotating roller A, the shaft. or, of-which is mounted in stand ards A A at the sides of the machine. The

tapes F are made flat, as herein shown. The

upper set of tapes.or belts are shown as made round and are trained over grooved pulleys E E, mounted on. a rotating shaft E that is rotatively mounted in the upper ends of the standards A The sheets D, of pasteboard or paper, are. carried between the adjacent laps o the upper and lower sets of belts.

. My improved sheet-delivery device comprises upper and lower sets of tapes or belts trained about front .and rear rollers carried in up er and lower vertically-swinging frames an located in position to receive between the upper and lower sets of belts or tapes thereof the sheets, discharged from the machine. The vertical -swinging movement of said frames and coacting upper and lower sets of belts enables the sheets to be delivered at dif- The structural details of said ferent levels. delivery device are shown as made as follows: The said frames carrying the upper and lower sets of belts comprise upper and lowerside members B B which are pivotally connected at their rear endsfresp ectively, with the shafts carrying the pulleys E and roller A, respectively, in am'anner to swing verticall at their outer en s horizontal upper and ower rollers B B respectively. The two side members of each frame are connected together in addition to the connection afforded by the shafts of the with eac associated rollers by means of a rod G, extending transversely between and attached to the lower frame members, and an arched stay-rod H similarly connects the outer ends of the upper frame members. Said upper and lower members at each side of the delivery-device frame are held separated by means of distance-blocks I), attached to one of the members of each upper and lower pair and having sliding engagement with the. members of the other pair.

B B designate, respectively, the upper and lower sets of belts or tapes associated with and constituting a part of the delivery device. The upper belts are trained about the upper outer roller B of the swinging frame andpulleys E carried on the shaft E and adjacent to the pulleys E. The lower belts ortapes are trained about the ,lower outer roller B of the frame and the roller A The parts are so arof the main machine. ranged that the adjacent laps of the delivery device tapes orbelts of the up er and lower sets are arallel and substantia lly in contact other, and inasmuch as said belts are trained about the same pulleys androller about which are trained the main carryingbelts of the machine at the discharge end of the latter the sheets of paper are directed from the belts E F of the main machine between the belts or tapes of the delivery device. In order to prevent the outer margin of a wide sheet from sagging when passing through the deliverydevice, lo'wer belts I I, supplemental toand located at the sides of the l0w'er belts or ta esB, are trained about the front lower rol er ,B of the device and about two pulleys I I, fixedto a shaft. IF, which is rotatively mounted in the lower frame members B of the sheet-delivery device. L

The sheets are delivered continuously to the truck C, and as the pile of sheets increases n height on said ing delivery device is moved upwardly. Preferably a guard rod or stick 0 is loosely connected at one end with the bail H and rests at its other end on the pile of sheets in order to hold the sheets vertically in place while being delivered upon the truck. After a suflicient number-of sheets have been delivered to the truck and before the truck is pulled away preparatory to placing another truck inposition tov receive the sheets the outer or swinging end of the delivery device is swung upwardly to the level of a shelfJ, :located above the space which receives the truck, and during the time required for placing an empty truck in position to receive the sheets the sheets are delivered to said shelf. After an empty truck is properly located to receive the sheets the delivery device is lowered, and

truck the vertically-swingerating upon sheets of cardboard and the li thereafter the group of sheets is removed from the shelf. Said shelf is herein shown as suspended from the ceiling by means of hangers The side of said shelf facing the delivery device is open, as shown at 9', to freely receive the sheets. At the other side of the shelf is located a swinging sto j, which arrests the sheets on the shelf an is adapted to be swung downwardly to permit removal of a group of sheets. A suitable guard j is ivoted at one side of the shelf and rests lig tly at its other end u on the sheets, so as to hold the same vertical yin proper position.

The said sheet-delivery device is preferably counterweighted to permit it to be swung from one position to another with the exertion of little power. The counterbalancing device herein shown consists of a suitable weight K, which is connected with the delivery device by means of a cable K, trained about suitable guide-pulleys k k and attached to a bail H, which is hinged to the transverse tie-rod G, before referred to.

I claim as my invention- 1. The combination with a machine for operating on sheets of cardboard or the like, of

a vertically-swingin delivery device hinged ranged concentrically with the pivotal axes of said frames.

2. The combination with a machine for o erating upon sheets of cardboard and t e like embracing upper and lower traveling belts or tapes between'the adjacent laps of which the sheets are conveyed through the machine, and upper and lower rollers at the discharge end of the machine about which said belts or tapes are trained,of a sheet-delivery device comprising upper and lower vertically-swinging frames which are separately hinged to the machine-frame to swing on pivotal axes concentric with said upper and lower rollers, rollers carried by the outer ends of said swinging frames and upper and lower sets of endless belts or tapes trained about the rollers carried by the machine and frame and between-which belts the sheets are received and thereby discharged.

3. The combination with a machine for olp e embracing upper and lower belts or tapes between the ad acent laps of which the sheets are conveyed through the machine, and upper and lower rollers about which said belts are trained, of a vertically-swinging delivery device at the discharge end of the machine are separately hinged to the machine-frame so as to swing onaxes concentric with the said upper and lower .rollers of the machine,

" rollers carried by the outer ends of said swing ing frames, up er and lower endless belts or tapes trained a out saidinner and outerrollers, and between which 1 the sheets are rec ived and thereby" discharged, a bail hinged 10 to the outer end of the lower frame, a coune terbalancing-weight and a cable connecting 'sald weight/with the bail.
