JOHN CLAUSE, or CHICAGO, ILLINOIS.

, PAPER-DAMPENINGMACHINE.

SPECIFICATION forming- To all whom it may concern:

Be it known that I, JoriN J. CLAUSE, of Chi cago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Paper-Dampening .Machines, of which the following is a specification.

My invention relates to improvements in means for placing the paper roll in the ma chine and removing it therefrom it has been dampened.

Heretofore paper-dampening machines have been so constructed that it is necessary to lift the roll of paper in and out of the machine, for which purpose various devices have been used, such as differential pulleys, cranes, and inclined planes.

The object of my invention is to provide a paper-dampening machine into and out of which the rolls may be moved without raising or lifting them at all, and thus at the same time dispense with the more or less complicated and expensive devices heretofore employed for raising the heavy rolls of paper, and avoid the trouble and inconvenienceincident to their BS8. l a

In the present invention the bearings for the axle of the dry roll are mounted upon two supports, guides, or frame-pieces ata suitable dis- I tance apart, so thatthe roll of paper may be suspended or rolled between them. The height of these frame-pieces or supports above the floor or approach to the machine is somewhat less than the radius of the roll of paper, so that as the paper is rolled into the machine the axle inserted in the center of the roll of paper will clear or come above the frame-pieces, and the plat-form or base of the machine between these frame-pieces is depressed or inclined toward the axle-bearings, so that as the roll of paper rolls into place its periphery will clear said base and be supported by its axle resting on the frame-pieces or guides. the roll have side openings, so that the axle of the roll restingupon the frame may be rolled directly therein without lifting the paper. The size of paper rolls usually varies from about fifteen to twenty-two inches in radius,

and the depression in the base or platform beneath thebearings should be made great enough to accommodate the larger rolls, while at the same time the axles of the smaller ones may Appiieation filed August .32, 1881.

iugs for removing the axle, the upper guidebars for said cross-head being on a level with the bearings, so that the axle may be rolled directly out of the bearing onto the guide-bars and out of the machine. 5

My invention will be more fully understood by reference to the accompanying drawings, which form a part of this specification, and in which Figure 1 is a plan view of a device embodying my invention. Fig. 2 is a side elevation. Fig. 3 is a detail sectional view of the sliding block and bearing, and Fig. 4 is a detail side view of the tension device.

In the drawings similar letters of reference indicate like parts.

In said drawings, A represents the frame of f the machine; 13, the friction driving-cylinder; O, the dryroll of paper, and D the dampened roll. E, which forms part of the cover of the watertank F, and is moistened as it passes by the sponge G, the lower edge of which is immersed in the water of the tank. J

The bearings a. for the axle a, of the dry roll are mounted on the frame-pieces or guides a in suitable sockets therein, the upper front edge of said bearings being on a level with the upper surface of said guides. The guides a are made tapering toward their outer ends, and their height issomewhat less than the radius The axle a is providedwith coljust the roll into place as the axle is rolled forward on the guides, and to keep the same in place after it rests in the bearings while the machineis in operation. The casting a, which forms the bottom or base of the machine, is depressed, cut away, or inclined under the bearings a, so that the periphery of the roll will clear the. same when the roll drops into the bearings. This depression or incline also The web of paper passes over the plate E serves to carry the roll into place when the same is rolled off thelevel of the floor in front of the machine, as the momentum the roll acquires while supported on the inclined base will continue to roll it along after its axle strikes the frame-pieces or guides. The axle a is provided with a tension device for regulating the tension of the web of paper, consisting of afriction-wheel, a on the end of said axle, friction clamping-jaws a (67, operated by the adj usting-screw a from the handle a through the connecting-gears a a", a, and a. The clamping-jaw a fits loosely on the screw a said jaw bearing against a shoulder or jam-nut on said screw, and the clampingjaw a is threaded to fit the screw a so that the operator, by turning the handle a, may tighten or loosen the clamping-jaws on the friction-wheel, and thereby increase or diminish the tension of the web of paper. The intermediate gearing between the handle and adjusting-screw a is employed simply to bring the handle into convenient position for the operator to reach it.v

H is a turn-table, which I usually provide in front of the machine for turning the roll square with the machine, and which is specially serviceable where there is a limited amount of room. g

The bearings 11 for the axle I) of the moistened roll are secured to or form part of the sliding blocks or cross-heads b mounted on the frame A, and which project between the guide-bars and Z)". The bearings b are U- shaped in form, and the lower leg of each of said bearings is on a level with the upper surface of the guide-bars I), so that the axle of the roll will be supported on said guide-bar when rolled out of the bearing. The movable part b of the bearing is secured in place by a pin,

b. The dampened roll is pressed against the I friction driving-pulley and allowed to recede therefrom as it increases in size by means of the chains 1) b connected with pulleys Z2 If on the shaft b, which is provided with a friction device.

0 represents a portion of the floor or platform in the rear of the machine, upon which the dampened rolls are delivered as they'are rolled from the machine. The height of the guide=bars If above this floor or platform should be a little greater than the radius of the larger-sized rolls of paper, so that the same maybe readily rolled from said guides without being raised.

I claim 1. In a paper-dampening machine, the combination of 'a turntable, an inclined base or platform, side rails or guides, a (6, adapted to support the roll from its axle, and provided with bearings for the axle, having side openings, all arranged and operating substantially as specified.

2. The combination, with the axle of the roll, provided with collars a", of tapering guides a provided with bearings having side openings, and base a, depressed under said bean ings, substantially as specified.

8. In a paper-dampening machine, the combination, with sliding blocks or cross-heads b, of bearings I), having side openings closed by movable parts 12 with guides 1), arranged on a level with said bearings, so that the roll supported by the axle may be rolled from said bearings on, said guides out of the machine, substantially as specified.
