MACHINE FOR SHAPING FLEECY MASSES.

SPECIFICATION forming part of Letters Patent No. 389,645, dated September 18, 1888.

Application filed April 26, 1887.

To all whom it may concern.-

Be it known that I, EDWARD GOLDMAN, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented a new and useful Improvement in Machines for Shaping Fleecy Masses, of which the folforms of mechanism and combinations thereof for the purposes set forth, all as hereinafter particularly described, illustrated in the drawin gs, and specifically pointed out in the claims.

Referring to the accompanying drawings, in which similar letters of reference point out like parts on each figure, Figure 1 represents an end elevation ofa machine embodying my invention. Fig. 2 is a side elevation thereof.

, Fig. 3 is a top plan view of the machine. Fig.

4; is a detail view of the mold-bed,one section of the retaining-bail lying flat, the opposite section lifted atiright angles to the plane of the bed. Fig. 5 isasectional view on theline w w of Fig. 4, having attached thereto one section of the bail lifted up. Fig. 6 is an enlarged longitudinal section of the blade-bearing stripper. Fig. 7 is a rear view of the stripper. V

In the drawings, A is the frame of the machine, consisting, essentially, of standards a a, and side braces, a a", supporting a table, B. The frame is further provided with an additional brace, 01*, extending diagonally from the four corner standards to a common center and supplied with a socket, 23, for a purpose to be presently set forth. The lower braces, a are provided with journal-boxes to carry a main shaft, 1, upon which shaft, outside of the frame, is a master-pulley, 2, provided with Serial No. 236.264. (No model.)

belting 3 to transmit motion to the pulley 40f rod is returned downwardly at its inner end to form a hook or bend, 9, which bend takes into an orifice near the edge of a rod, 10, for a purpose hereinafter explained. The rod 10 extends outwardly beyond the frame of the machine and is pivotally connected by means of a strap, 12, to the shifting-bar c by a setscrew, 7. Under the bar 10 isashort orificed collar, 13, which turns with the shaft 11.

14. is a brake-shoe the arm of which is pivotally connected within the fork of a hanger, 15, depending from brace a, and said shoe by swinging of the lever O is, through a bellcrank lever, 16, brought against the periphery of the pulley 2 simultaneously and by the same action that operates the belt-shifters 0 The vertical shaft 11 is set in motion in the following manner: Upon the driving-shaft 1, inside the frame, is a small pulley, 17,which, through belting 18, operates a pulley, 19, upon an upper shaft, 20, journaled in the opposite braces, a, said shaft reaching across the frame away from its center. Midway of the shaft is a worm, 21, meshing into a wormwheel, 22, rigidly attached to the-vertical shaft 1l,which causes the mold-bed to turn on its eccentric axis concurrently with said shaft 11. The several operative pulleys and gearings are arranged to have relative velocities, and I have found that the best results are obtained by the proportions herein set forth. The worm-shaft 20 is caused to turn one hundred times a minute, each revolution operating one of the one hundred pinions of the worm-wheel 22, the pitch being five-sixteenths of an inch. Gon'se quently said wheel will turn completelyonce in a minute.

- The shaft 11 extends downward to the crossbrace a and has its bearing within a socket, 23. Said shaft passes upward through the table B,

through a washer, 2-1, and from thence through the eccentrically-located hub 25 of the moldbed 26. Above said moldbed is a collar, 27, and a screw-plate, 28, intermediatel y embracing the forward end of the metallic guard 29 and brace-plate 30. Upon the table B are posts 31 32, to which posts the guard 29 and brace-plate 30 are rearward] y. respectively, rigidly attached by screws 33. From the points of attachment to said posts the guard 29 and plate 30 each incline upwardly and obliquely, and after passing over the edge of the inold-bed extend forwardly until they reach the shaft 11. Said guard and brace-plate at their forward ends are bent over to a horizontal plane, and said heat over portions are pierced for reception of the uprising end of the shaft 11, which is free to turn within the orifices of said guard and brace-plate. The horizontal end portions of these members are rigidly confined between the collar 27 and screw-plate 28, as before set forth, said screw plate being orificed for passage of the uppermost end of shaft ll. (See Fig. 3.)

Dis a stripper in the form of a hollow conical frustum, having a huh, (I. Externally and rigidly attached by screws (1 to the stripper are blunt-edged blades (1, curved in direction of their length and extending the full length of said stripper.

E is a short shaft which passes through the huh (I, to which it is screwed by set-serew d, and extends from thence inside the stripper, where it is finally seated within recess (1. (See Fig. 6.) Said shaft extends in an opposite direction to and within the pulley 4.,which pulley is in alignment with the master-pulley 2, and is connected thereto by belting 3, as heretofore set forth. The main shaft 1, when the machine is operated, revolves four hundred times a minute, and the relative diameters of the master-pulley 2 and stripper-pulley t are such as to cause the latter to make four thousand revolutions in the same period of time. The shaft E passes within journal-boxes d of ordinary construction, resting upon support (1, firmly bolted upon the table B. The moldbed 26 has its upper surface in an oblique plane, each section provided with a recess, 34, to conform to the desired shape of one surface of the completed fleeey mass.

To enable all skilled in analogous devices to fully understand and practice my invention, I will describe its adaptation to manufacture shoulder-pads, for which Letters Patent aforesaid have been issued to me.

The mold-bed shown in the drawings is constructed to receive blanks for two pads falling, respectively,within the recesses 3t. (See Fig. 5 and dotted lines, Fig. 1.) Upon said bed is placed a blank sheet of fleecy materialsueh as a cotton bat. Some of the thickness of this mass will necessarily rise above the upper plane of the mo1d-bed and the greater proportional depth will obviously appear exposed above the thinnest part of the bed. Vhen motion is imparted to the machine, the blank mass will be trimmed off to the desired configuration.

In order to prevent the tlecey mass during manipulation from being torn from the bed, I provide hinged wire bails 35, adjusted to swing on their pivots toward each side of the bed and over the blank mass, by which means said mass will be held down, and, as will be readily understood, may be withdrawn by lifting up the respective bail.

By reference to Figs. 4 and 5, it will be seen that each bail has a cross-rod, 36, provided with a curve, 37, which holds down that part of the mass under said OIOSS l'Od. After the blank has been thus confined, it is now ready to have its whole surface trimmed off. As before described, the mass does not extend in uniform thickness above the bed by reason of portions thereof being sunk within the reecsses 3i. It is therefore obvious that in order to secure the desired configurative finished surface the larger quantity of substance will be tri m med off where the greater depth appears above the upper oblique face-line of the bed. This is effected by means of the horizontal revolution of the bed around its axis adjusted away from its center to impart eccentric mo tion to said bed, thus presenting from time to time required surfaces to the action of the trimming-blades. Motive power having been transmitted to the machine through the driving-pulley, the stripper D is caused to revolve at a rapid velocity, in practice about four thousand revolutions in a minute. At the same time, through revolution of the shaft ll, actuated through the worm-wheel 22,the moldbed, carrying its caged mass, is caused to turn eccentrically once in the same period of time. As the moldboard is turning, the caged mass carried thereon is caused to travel underneath the metal guard 29, and it will be readily understood that no portions beneath said guard can be stripped off. As soon, however, as the portions of the rotating mass are withdrawn from the guard, such freed portions are subjected to the action of the rapidly-revolving blades, which blades are gaged to approach close to but not into actual contact with the traveling mass. As before set forth,the blades of the stripper are curved in direction of their length, and the result of their rapid revolution is to create a powerful centrifugal suction that strips off filaments of the mass until its exposed surface is trimmcd down to the desired configuration. iVhen this is accomplished, the bails are swung up on their pivots, and the blanks are withdrawn and replaced with others for like treatment. After withdrawal, each blank is cut off by shears or dies to impart the required configuration to its perimeter.

Having now fully described my invention and the manner of its operation,what I claim, and desire to secure by Letters Patent, is

1. In a machine for shaping fieecy masses, mold-bed 26, having one or more recesses upon its surface provided with swinging bails 35, whereby to confine material within said reeesses, the moldbed being eccentrically j on rnaled on a vertical shaft, as and for the purpose intended, substantially as described.
