MACHINE FOR FINISHING GARMENT-PADS OF MATTED OR FELTED FIBERS.
Specification of Letters Patent.. Patented Dec. 18, 1906.
Application filed November 2,1904. Serial Ho. 231,116.
To all ivhom it may concern:
Be it known that I, Gtjstav Goldman, of Baltimore, Maryland, have invented a new and useful Machine for Finishing Garment5 Pads of Matted or Felted Fibers, which invention is fully set forth in the following specification.
This invention relates to machinery for use in making garment and other pads, and more
i o particularly to means for imparting a smooth and sightly finish to said pads. According to one method devised by me for making such pads, a sheet or strip of fibrous material having the fibers united by a suitable binder, as a
15 resinate, is' fed to a machine which acts to skive out a portion of said sheet on tapering lines, after which the pads are cut out by a die-press designed for that purpose. The pads, whether made by the above method or
20 otherwise, are liable to present more or less roughened surfaces after they are cut out or . otherwise formed, and the present improvement is designed to smoothly finish said surfaces, so as to render the pads more attractive
25 in appearance.
With this object in view the invention consists in a revolving heated roller or cylinder and a carrier-belt, held in close contact with the surface of the cylinder for a portion of its
30 circumference and acting to hold the pad in close contact with the hot surface of the roller or cylinder. In cases where the fibrous material of the pad is united by a binder, which softens under the influence of heat, the hot
3 5 cylinder acts to soften the binder and to press the projecting fibers on the surface of the pad down to a smooth surface, where they are seized and held by the binder. In other cases, where the binder is one not rendered
40 active or sticky by heat, the pads may be fed to the finishing-press while the binder is only partially dried; or the surfaces of the pad may be subjected to treatment with a solvent of the binder employed before being treated
45 by the finishing-press. Preferably the carrier-belt has a concave surface, the concavity being designed to conform to the taper of the pads to be treated. Moreover, for the purpose of more effectively heating the surfaces
50 of the pads while they are retained between the carrier-belt and the surface of the cylinder a heated concave surface is arranged close to the cylinder, so that the belt carries the pads between two heated surfaces and in
contact with one of them. When the pads 55 emerge from between the cylinder and the belt, it will be found that that surface of the pad which was in contact with the cylinder is smoothly finished, and, for the purpose of finishing the other surface, the pad is then 6c turned over and again passed between the same or a similar belt and the cylinder. Preferably the cylinder and concave heated surface are made long enough to permit two carrier-belts to operate simultaneously in 65 conjunction therewith, and means are providedf or receiving the pads from the first belt, turning them over and presenting them to the second belt, by which they are again subjected to the action of the heated cylinder, 70 and then delivered from the machine, preferably to a suitable carrier, which removes them to any desired place of deposit.
The inventive idea involved may receive a great variety of mechanical expressions—one 7 5 of which is, for the sake of illustration, shown in the accompanying drawings, in which—
Figure 1 is a side elevation, and Fig. 2 is a longitudinal section, of the invention. Fig. 3 is a top plan view, and Fig. 4 is a cross-sec- 8c tional view, of the carrier-belt.
Referring to the drawings, 1 is the framework of the machine, upon which the hollow closed cylinder 2 is mounted to turn. A heating fluid, as steam, is admitted to said cylin- 85 cler through its trunnions 3 from pipe 4, as shown in Fig. 1, the condensed steam being drawn off through pipe 5. It will be understood that said pipes 5 and 4 are stationary and do not turn with the trunnions. The 90 cylinder 2 is provided with a gear-wheel 6, which meshes with a gear 7, keyed on the shaft with the gear 8, which in turn meshes with a gear 9 on a shaft to which is keyed driving-pulley 10. driven by a belt 11 from 95 any suitable source of power.
Supported on the framework of the machine in any suitable way under the cylinder 2 is a steam-box 12, whose upper surface is concave, as shown, and lies in close prox- 100 imity to the under surface of cylinder 2. Steam is admitted to said steam-box 12 through the steam-pipe 13, Fig. 2. A belt 14 is passed around four cylinders 15, 16, 17, and 18, Fig. 2, and under the cylinder 2, 105 preferably near one end of said cylinder. This belt 14 is hollowed out in cross-section, as shown at 19, Fig. 4, the particular charac
ter of the hollo wed-out or concave surface of the belt being, made to correspond to the taper or slope of the pad that is to be treated. The cylinders 15, 16, 17, and 18, around 5 which said belt passes, may be, if desired, and preferably are, slightly concaved at the point where the belt passes around the same, as shown at 20, Fig. 3. Belt 14 may be made of any suitable material, and the con
10 cavity may be formed in any suitable way, preferably by building up the belt upon the sides, so as to effect the desired shape thereof in cross-section.
In practice there are two of the belts 14,
15 identical in construction and in manner of mounting, one, however, being located near one end of cylinder 2 and the other near the opposite end thereof. The two belts 14 are driven by means of power applied to a pulley
20 21, Fig. 2, and transmitted by belt 22 to the cylinder or roller 16, which is geared in any suitable way, as by sprocket - chain 23, to the cylinder or roller 17. The pads are delivered for treatment onto one of the belts
25 14—say the lower belt of Fig. 3—and are passed in the direction indicated by the arrows in Figs. 2 and 3 downward between the belt and the cylinder 2, the cylinder revolving in the direction indicated by the arrow in
30 Fig. 2. As said pads emerge from between the belt 14 and the cylinder 2 on the lefthand side of said cylinder as viewed in Figs. 2 and 3 it is delivered to a series of continuously-moving belts 24 or other suitable car
35 rier, which travel in the direction indicated by the arrows in Figs. 1 and 2, being propelled by the rollers 25 and 26. The belts 24 deliver the pads to a continuously-revolving table 27, whose surface is composed of raised
40 ribs, preferably annular ribs, the table revolving in the direction indicated by the arrows in Fig. 3. On the opposite side of table 27 from the carrier-belts 24, which act to carry the pads downward, is a similar series
45 of belts 28, which, however, move in the reverse direction from the belts 24—that is, they move in a direction to carry the pads upward from the table to a second series of belts 29. The belts 28 and 29 are passed
50 around suitable rollers, and both of them move in the direction from left to right, as shown in Fig. 3. The belts 28 and 29 serve to lift the pads and deliver them onto the upper surface of the cylinder 2, which revolves
5 5 in the direction of the full-line arrows shown in Fig. 3, thereby carrying the pad around with the cylinder and delivering it between the upper belt 14 of Fig. 3 and said cylinder. It will be observed that as the padpassesbe
60 tween the first belt 14 and the cylinder 2 the upper surface of the pad is the one that comes in contact with the upper cylinder 2 and is therefore the one that is smoothed by the action of said • cylinder. As the pacl
65 passes from under the cylinder and is deliv
ered to the belts 24 and the revolving table 27 and by said table to the belts 28 and 29 the finished or smoothed side of the pad is uppermost, the lower side thereof being the one that has not been effectively finished. 70 As the pad is passed from the belts 29 onto the cylinder 2 it will be observed that it is the lower or unfinished side of said pad which comes in contact with said cylinder and that when it is carried between the second belt 75 and said cylinder it is this side—that is, the side which was formerly the under side— which now becomes the upper side and the one that is in contact with the cylinder, and hence the one that is finished thereby. It 80 will thus be seen that by the time the pad has been passed by the two belts under the cylinder both surfaces thereof have been submitted to the smoothing or finishing action of the cylinder 2. 85
For the purpose of imparting motion to the belts 24, the table 27, and the belts 28 and 29, a roller or shaft 30, around which belts 28 and 29 pass, is geared in any suitable way, as by Motion-gears, to the shaft of the 90. roller 16, as shown at 31 in Fig. 3. This shaft 30 carries a pulley 32, and a like pulley 33 is mounted on the shaft of the roller 25 on the opposite side of the machine. Two idler-pulleys 34 and 35 are mounted one on 95 each side of the machine, and a belt 36 is passed over the pulley 32 around the table and in a groove formed in the periphery thereof, over pulley 33 and around pulleys 34 and 35. It will thus be seen that .the belts 100 24, 28, and 29 and the table 27 are all driven by the same belt, and therefore move at the same speed. The lower turns of the belts 28 occur very close to the surface of the table 27, but not near enough thereto to enable the 165 pads carried by said table to readily be picked up by the belts 28, and in order to insure this action rigid fingers 37 project downward from the framework supporting the belts upon which the lower end of the no belts 28 turn, said fingers 37 being arranged so that the lower ends thereof project into the grooves formed between the ribs 38 on the table 27, and as said table revolves the contact of the pad with said ribs enables 115 the table to slide the pads up along the fingers 37 until they partially project over or come in contact with the belts 28, when the latter pick them up and carry them onward, as before indicated. When the pads have 120 passed from between the second belt and the cylinder 2, they may be delivered in any suitable may, as by means of a chute 39, Fig. 1, to a carrier 40, by which they are removed, to any suitable or desired point and deposited 125 in a receptacle 41 or in a pile to be removed by the workman.
It will be observed that by the. mechanism described it is possible to bring the surfaces of each pad into close smoothing contact with 130
