POUNDING-UP ROLL.

Specification of Letters Patent.

Patented Mar. 12, 1912.

Application filed April 27, 1911. Serial No. 623,600.

To all whom t may concern.' Be it known that I, JOSEPH; GOULDBOURN,

a subject of the King of Great Britain, re? siding at Leicester, Leicestershire, England,

have invented certain Improvements in Founding-Up Rolls, of which the following description, in connection with the accompanying drawings, is a specicatio-n, likel reference characters on the drawings indicating like parts in the several figures.

This invention relates to pounding up,

leveling or smoothing rolls used in the manufacture of boots and shoes, and particu-l larly adapted for use in re-formlng the boty toms of turn shoes.v

The general o-bject of the present invention is to providean-improved roll for the purposes above set forth which roll is more effective in operation and of greater durability than rolls as hitherto constructed for these particular purposes.

In the roll to which this invention particularly relates there is combined with the roll body a number. of beating members carried by the said body, the said members being arranged to eXert bot-h a pounding-up effect and a smoothing action upon the surface of the material under treatment.

According to the illustrated embodiment of the invention the roll comprises a body part having a number of recesses or slots in which are received shank portions of a pluy rality of blocks or beating members. The

shank portions of the blocks or beating members are adapted to slide in the recesses or slots and under the influence of centrifugal force the said blocks are moved to the eXtreme outer position when the roll is rotated. The blocks or the Shanks thereof are provided with projecting parts to engage corresponding parts of the body part to limit the movement outwardly of the blocks when under the. influence of centrifugal force and to prevent their disengagement ,froml the roller. When the Ablocks have been depressed against the body part the Whole will form a circular roller.

Conveniently, the 'body part of the roll may be made up of a number of disks placed side by side on a shaft or spindle, each of the' disks being providedwlth recesses or slots for the reception of the shanks of the beating members. When the body part is thus composed of separate disks they may each be secured to the shaft or spindle or one alone may be secured to the said Ishaft the others being loosely mounted thereon and made to revolve with the fixed disk by projections on t-he beat-ing members of each disk which projections extend between the adjacent blocks of the neighboring disk and by engaging the sides of the said blocks impart rotary motion to the loose disk.

` A convenient embodimentof the invention Will now be described by way of eX- ample and then the invention particularly pointed out in the claims but it is to be understood that the construction and general arrangement of the parts may be varied without departing from the spirit of the invention.

In the drawings, Figure 1 is a side elevation of a beating roll` having centrifugalbeating elements; is a section through Fig. 1.

In the embodiment of the invention a number of disks 2, forming a cylindrical Fig. 2

hub, are mounted upon a shaft 4 and are secured thereon by a collar 5 at o-ne end formed upon or fixed to the shaft. At the 'other end of the series of disks the shaft is provided with a 'threaded stud upon which is screwed a nut 6 which through a washer I 8 forces all the disks into contact. Conveniently the washer may form the inside wall of a plain surfaced roller` 10 for use in the processof manufacture of a boot or shoe which roll is thus, by means of the same screw, secured to the end of the shaft. Each disk 2 is formed in' one'of its faces with a number of Vrecesses or slots which conveniently are not disposed radially of the roll but are inclined away somewhat from the radius of the roll in the direction of rotation.` The recesses o-r slots eachreceive the shank 12 of a block or beating member which extends from the shank rearwardly away from the direction of the v` having, in combination,

part l5 which, at certain times,

which is cut away at the center of the face having the recesses to afford space for the said projections. Sufficient clearance is provided between the projecting parts l5 of the shank and the inner surface 16 of the disk to permit the blocks to move outwardly to the necessary extent under the influence of centrifugal force during the rotation of the roll before ,the said projecting parts: come int-o engagement with the inner surface of the disk.

Each, or some of the blocks may be provided with projecting parts 18 on one of their faces which engage between the blocks of the nei hboring disk and thereby insure rotation o the several disks when the shaft is revolved. When the roll is stationary and the blocks closed in against the body part the curved outside faces of the said blocks will constitute a circular roll. When, however the roll is rotated' the blocks will, under the influence of centrifugal force, be moved outwardly from the disks as far as is permit-ted by the projections on the shank and thereby be brought into a position to act upon the work which is presentedto and pressed vagainst the surface of the roll.

Having explained the nature of this invention, I claim as new and desire to secure by Letters Patent of the United States l. An apparatus of the classv described having, in combination, a body roll, com prising a number of disks placed side by side, a plurality of beating members carried by each of the disks, the beaters being arranged to exert both a pounding-up and a engage@ l with the inner surface 16 ofthe body part' smoothing action upon, the surface of the` material under treatment and means for driving the roll.

having, in combination, nular series of beating wlnchmembers has a shank portion, a body wardly under the infiuence of centrifugal force when the roll is rotated, and means for limiting the outward movement of the `beat-ing members.

3. An apparatus of the class described a body roll having a plurality of recesses of annular series of beating members having shank portions adapted to slide outwardly therein under the influence of centrifugal force when the roll is rotated, the beating members in said annularseries beor slots, a plurality -shanks retained in said ing arranged in staggered relationwith one another.

4t. An apparatus ofthe class described having, in combination, a body roll having a plurality of recesses or slots, a plurality of beating members having shank portions adapted to slide outwardly therein under the influence of centrifugal `force when the roll is rotated, the beating members being arranged in annular series and staggered and each beater having a projection eXtend ing laterally across the line dividing it from the neXt annular series.

5. An apparatus of the class described having, in combination, a body roll made up of a number of disks placed side by side, each of the disks being provided with recesses or slots, beating members having slots, a driving shaft to which one of said disks is secured, and interlocking projections on the beating elements compelling the other disks to rotate with the shaft.

6. An apparatus of the class described having, in combination, a body roll made up of a number of disks 2 placed side by side, each of the disks having in one side face a plurality of slots inclined to radial lines of the roll in the direction of rotation, beating members having beating heads and relatively thin Shanks sliding in said slotsv and having means to limit the sliding movement.

7. An apparatus of the class described having, in combination, a shaft, a collar fast thereon, a beating roll on the shaft adj acent to the collar, a washer at the opposite end of the roll, a threaded stud projecting from the end of the shaft, a `nut on said stud which through the washer clamps the roll against the collar, and a hollow plain surfaced roller formed on the washer and inj closing the nut. 2. An apparatus of ythe class described,y a plurality of anmembers, each of- 8. An apparatus of the 'cla-ss described having a carrier, and a plural-ity of annular Aseries of beating members, restrained from forward and backward tipping movement therein, the members of each series being yielding independently of the other series and each of the beat-ing members having a curved leading surface adapted to exert a pounding up action upon the surface of the material under treatment, and a relatively long following and'rubbing surface adapted to exert in turn a smoothing action upon the said surface of the material.

In testimony whereof, I have signed my name to this specication in the presence of two subscribing witnesses.
