ARNOLD HOFF, OF NEW YORK, N. Y.

HAT-PRESS.

To all whom it may concern:

Be it known that I, ARNOLD H01 1, a subject of the King of Hungary, residing at New York, in the county of New York and State of New York, have invented new and useful Improvements in Hat- Presses, of which the following is a specification.

My invention relates to hat presses, and;

has as its principal object to provide mechanical means for holding and stretching the material of which hats are sometimes made, such as felt, velvet or the like, so that the work can be performed with advantage by only one operator, whereas heretofore press machines used for this purpose, in which one mold is pressed against another fixed mold, required the attendance of the material from the other side so that the tension is under the complete control of the operator.

The invention is illustrated in the accompanying drawings which show the device in its preferred form of construction; I

Figure 1 represents a side view of the device. Fig. 2, a rear view of the same, partly in section. Fig. 3, a plan, a few parts being removed for the sake of clear ness. Fig. 4 is a view showing the position of the grippers relative to the molds and to the operator. 7 V

In the separate views the same part is designated by the same reference character.

Referring more particularly to the drawing, an upright post 1 is mounted in the press machine as a support for a tapped and slit block 2 adapted to be adjusted on the post into any desired position. By means of a clamp tion of the block, the latter can be secured to the post in adjusted position The block 2 carries a horizontal shaft 4 which extends an equal distance beyond the block at both sides. On this shaft two' plates 5, arranged at opposite sides of the block 2 and mounted by means of bushings'on the shaft, are adapted to rock. Each plate carries at the inner end a fillet 6 arranged at right angles Specification of Letters Patent.

to the shaft 4. One end of this fillet projects beyond the plate, and the projecting part is held between two wing nuts 7 fitted ona treaded spindle S. The spindles 8 are pivoted at 9 to a bracket 10 which is se cured to the block 2. It is evident from this arrangement that theplates willbe secured 1n position by the nuts 7 and also that they can be set, independently of one another, in different angular positions on the shaft 1 by an adjustment of thenuts on the spindles 8.

Each plate 5 supports, by means of two bearings 12, a sleeve 11. Each bearing 12 is slotted for the reception of an eyelet 15 which embraces the sleeve and which is fitted with a-treaded stud passing through the base of the bearing and through a 1011- gitudinal slot 11 made in the plate 5 'By' means of a wing nut 13, fitted on the stud and bearing against the lower surface of the plate 5, the eyelet 15 can be actuated for clamping the sleevelto the bearing 12 and securing the latter to the plate 5. Owing to this arrangement the sleeve can be adjusted to and secured in any desired position on and at various angles to the plate 5. The sleeve can moreover be adjusted longitudinally in the bearings, an operation which is shuts against the guide 20 and against a collar 22 on the rod, thereby tending to ,hold the frame in the position shown in Fig. 1. The collar 22 is secured to the rod 19 by means of a wing screw and can easily be shifted for varying the pressure of the spring. The rod 19 is secured in position simply by means of a wing screw 23,, fitted in one of thecrosspieces 18 so that it can I easily be removed. By this arrangement, therefore, the spring 21can readily be replaced by oneof'more or less strength.according to requirements. The rod 17 terminates at the front in a vertical socket 24 containing a conical stud 25 which is connected to a horizontal plate 26." The free end of the stud 25 is threaded and fitted with a Wing nut 27 by means of which it'fiiand their holders and the manner in which can be secured, together with the plate 26,,

to the socket in various angular positions. Hinged to the plate 26 is another plate 28 so as to forma pair of jaws between which to grip the hat material, one jaw being preferably provided with teeth 29 which take into a groove 30 made in the other aw so that a firm grip on the material is obtained. Springs 31 tend to close the jaws which are opened by means of two cams 32 connected to opposite ends of a shaft 83 held by the lower plate. The cams are adapted to retain the jaws in open position and are operated by means of levers 34 connected to the cams one to each. One of the levers 34% is connected by means of a cord or wire 35 to a separate treadle by means of which the cams can thus be operated so as to allow the jaws to close over the hat material which the operator inserts between them with the hands.

The device is set up so thatthe grippers are disposed at one side of the molds 36 (Fig. i) opposite the position of the op erator. Two corners of the material 37 are inserted in the grippers, one in each pair, and the separate treadleis operated so as to cause the jaws to close. Then the operator grips the opposite corners of the material and stretches it out between the molds 36, the frames 17, 18 and 19 being thereby moved forward in opposition to the springs 21. l Vhen the material has its proper tension and position, the machine is operated for raising the lower mold and pressing the material into hat shape. Finally the op- .erator turns the cams 24 for operating the jaws and releasing the material from the grippers. V j

The two frames are preferably set in a diverging position, as shown in Fig. 3, so that the distance between the grippers will be increased simultaneously with the forward movement of the frames. In this manner a diagonal stretching of the material will take place. The plates 5 can be adjusted about the shaft 4 to such a position that the grippers, simultaneously with being pulled forward move the material closer to the fixed mold. Owing to the universal adjustment of the elements provided for, the grippers can always be set in a position 'suitable for the kind of work performed.

The sleeves 14 as well as the plates 5 may be provided with scales, so that the adjustment of elements for a particular kind of work, when once arrived at by experiments, can be noted for future reference. The springs 21 can also be exchanged or adjusted to suit the nature of the various materials in use.

The actual construction of the grippers they are mounted and actuated may be vajried according to requirements.

aving thus described my invention, what I claim is 1. The combination with hat shaping blocks, of resiliently mounted frames adjustable at difierent angular positions to said block, adapted to held between them the hat material, and automatically to stretch it in'divergent directions while a single operator stretches the same in a different direction, substantially as and for the purpose set forth.

2. The combination with hat shaping blocks of reciprocating frames adjustable in different angular positions on a table mounted in front of said blocks, holders pivotally mounted on the fore-ends of said frames adapted to grip a hat material, and to stretch it in diverging directions while the operator stretches same in another direction, substantially as and for the purpose set forth. 7

3. The combination with hat shaping blocks of a device for stretching the hat material, comprising a vertical post, a slit and tapped block adjustable at different heights on said vertical post, a pair of tables hingedly mounted on a shaft carried by said block and adapted to be fixed in different oblique positions on same, sleeves mounted one on each of said tables adjustably in different angular positions thereon, a frame composed of parallel rods and cross pieces carried by each of said sleeves, adapted to reciprocate in respect thereto, adjustable resilient means carried by said frames to actuate them in one direction and grip ping means pivotally mounted on said frames, adapted to engage one corner each of a hat material, substantially as and for the purpose set forth.

4-. In a device of the character described, in combination, grippers for hat material comprising a lower plate pivotally mounted on reciprocating members, said plates having each groove near its front edge, upper plates hingedly mounted on said lower plates, having tongues or teeth registering with said grooves in the lower plate, resilient means for keeping said lower and upper plates in a position of closed jaws, cam levers for opening said jaws, and treadle controlled means connected to said cam levers for closing said jaws, substantially' as and for the purpose set forth.

In testimony whereof, I afiix my signature in the presence of twowitnesses.
