HAT-FRAME MACHINE.

SPECIFICATION forming part of Letters Patent No. 779,831, dated January 10, 1905.

Application filed March 12, 1904. Serial No. 197,807.

To all whmn it perry concern:

Be it known that I, DECATUR D. BEAITY, a citizen of the United States, residing at Grass Valley, in the county of Nevada and State of California, have invented a new and useful Hat-Frame Machine, of which the following is a specification.

This invention relates to machines for making wire hat-frames; and it has for its object to provide a device of this class which shall be simple in construction, easily manipulated, efficient in operation, and by means of which hat-frames of various sizes and shapes may be easily. quickly, and conveniently produced.

With these and other ends in view the invention consists in the improved construction, arrangement, and combination of parts, as will be hereinafter fully described, and particularly pointed out in the claims.

In the accompanying drawings has been illustrated a simple and preferred form of embodiment of the invention, it being understood, however, that I do not thereby limit myself to the precise structural details therein exhibited, but reserve the right to any changes, alterations, and modifications that lie within the scope of the invention and which may be resorted to without departing from the spirit or sacrificing the utility of the same.

In said drawings, Figure 1 is a perspective view of a device constructed in accordance with the principles of my invention, showing the same in the position occupied in the first step of the manufacture of a hat-frame. Fig. 2 is a vertical sectional view of the machine. Fig. 3 is a horizontal sectional view taken on the line 3 3 in Fig. 2. Fig. 4is a perspective view showing the upper part of the machine in the position occupied in the second step of the process of manufacturing a hat-frame. Fig. 5 is a perspective view showing the upper part of the machine and a hat-frame in the third step of manufacture. Fig. 6 is a perspective view of the upper part of the machine, illustrating the manner of using the same for the purpose of manufacturing a bellcrown hat-frame.

Corresponding parts in the several figures are indicated by similar numerals of reference.

In the construction of my improved hatframe machine is comprised a bench or table 1, preferably raised upon legs 2 and having a perforation 8, in which is fitted a tube 4, affording a bearing for a spindle 5, the upper end of which carries a platform 6.

7 designates a sleeve fitted upon the tube 4, which latter is revoluble in the perforation 3 of the table, and said sleeve is provided at its lower edge with an annular flange 8, supporting a block 9, which is secured to said flange by means of set-screws 10.

11 designates a supporting-ring which is secured upon the table 1 concentrically with the perforation 8 and which supports the flange 8 of the sleeve 7.

12 is a set-screw extending through an opening 13 in the block 9, through an opening 14 in the sleeve 7, and through a corresponding opening in the tube 4, the inner end of said setscrew bearing against the spindle or rod 5, which may thus be secured at any desired adjustment relatively to the tube 4. It will thus be seen that the block 9, with its related parts, is revoluble with the tube 4 and that the spindle or rodcarrying the platform 6 has a wide range of adjustment.

The block 9 is preferably elliptical in shape, its major diameter being from one-half to one inch in excess of its minor diameter, corresponding with the ordinary oval or elliptical shape of a hat-frame. Arranged eq uidistantly around the circumference of the block 9 are a pluralityof brackets 15,said brackets affording bearings for shafts or pins 16, upon which are pivotally mounted the stretching members 17, each of which comprises an inwardly-extending arm 18 and one or more upwardly-extending arms 19. In the accompanying drawings each of the stretching members is provided with two upwardly-extending divergent arms 19; but it is to be understood that a single arm or more than two arms may be employed when desired without departing from my invention. Each of the arms 19 carries at its upper end an inwardly extending hat-ring-supporting plate 20, having at its inner end a segmental flange 21, the outer edge of which has a groove or recess 22.

The inwardly extending arms 18 of the stretching members are provided at their inner ends with notches 23, engaging an annular flange 2 1 of a sleeve 25, which is loosely mounted upon the tube 1. Suitably connected with the sleeve 25 is a rack 26, engaging a pinion 27, mounted upon a shaft 28, which extends through a recess or perforation in the block 9 and through a tubular bearing 29, secured exteriorly to said block. Said tubular bearing carries at its outer end a ratchet member 30, engaged by a pawl 31 upon a lever 32, which is securely connected with the shaft 28. The pawl 31 is spring-actuated, and it has a handle 33, by means of which it may be released from engagement with the ratchet member 30. Thus by compressing the pawl-handle 33 and the lever, 32 the pawlwill be disengaged from the ratchet member, and the shaft 28 may be turned in either direction, thus causing the sleeve 25 to be raised or lowered by the pinion 27 engaging the rack 26. By thus raising the sleeve 25 the inner ends of the arms 18, engaging the flange upon said sleeve, will be elevated, thus forcing the upwardly-extending arms 19 of the stretching member 17 in an outward direction. When the sleeve 25 is lowered, the operation is reversed, and the upper ends of the arms 19 of the stretching members will be moved radially in the direction of each other.

It will be observed that the block 9, with all its related parts, is revoluble with relation to the table and that the rack-bar 26 is easily accommodated within the ring or annular support 11.

Wire hat-frames of the class which are manufactured by means of my improved machine are made up of a plurality of rings or so-called crown-wires and rib-wires intersecting the same and connected therewith by bending or folding around them. In the manufacture of a hat-frame crown-wires of suitable size are provided. The platform 6 of the device is adjusted at a suitable distance from the upper ends of the arms 19 of the stretching members to form a hat-crown of the desired height, the height of the hat-crown being equal to the distance between the said platform and the upper sides of the plate 20. By manipulating the shaft 28 the stretching members 17 are rocked upon their fulcra, bringing the upper ends of the arms 19 in the direction of each other, and one of the rings or crown-wires is then placed upon the plates 20. The stretching members are now expanded, thus causing the segmental grooved flanges 21 to engage the crown-wire, which is thereby stretched or strained in an outward direction and retained securely, while the rib-wires are wrapped around diagonally opposite points of said crown-wire, the lastrib-wire placed in position being wrapped around the remaining ribwires, and thus connecting them securely at the pointof intersection. The arms 19 of the stretching members form gages, enabling the operator to wrap the rib-wires upon the crownwires at equidistant points, said rib-wires being adjusted either between the individual stretching members or between the arms 19 of individual stretching members, as may be preferred. After being wrapped around the crown-wire the rib-wires are left in an upstanding position, as clearly shown in Fig. 1, where the first step of the operation is illustrated. The shaft 28 is now manipulated to release the crownwire,which is now permitted to drop down upon the platform 6, after which another crown-wire is placed in position, the stretching members are expanded, and the ends of the ribwires are twisted around the crown-wire now held by the stretching members, the ends of the rib-wires being permitted to extend radially from the crown wires. The latter is now released, and the partly-completed frame is removed from the machine and inverted, the lower crown-wire being again placed in engagement with stretching members, whereby the hat-frame is securely held, while a brim-wire(designated 50) is made fast to the hat-frame by twisting the ends of the rib-wires around said brim-wire, the latter being meanwhile held by the hand of the operator. This having been accomplished the projecting ends of the rib-wires are cut oil and the hat-frame is finished.

During the process of manufacture the operator may sit or stand in front of the machine, which latter is rotated by hand as the operation progresses. It is obvious that any desired number of crown-wires may be used by moving the platform 6 step by step in a downward direction, each downward movement being equal to the distance that the crown-wires are to be spaced apart.

It will be observed that the platform 6 is provided with radial notches 34; for the accommodation of the vertical arms 19 for the stretching members, said platform extending beyond said stretching members, so as to afford a supporting-surface exteriorly of the latter. When it is desired to manufacture what is known as a bell-crown hatframe that is, a hat-frame in which the uppermost crown-wire of the crown is larger than the one at the inner edge of the brim-1 first connect the rib-wires with said large crown-wire. When after this first step the partly-made frame is disconnected from the stretching members andinverted, it is placed upon the sup= porting-platform 6 exteriorly of the stretching members, while a smaller crown-wire is IIS placed in position to have the rib wires wrapped around it. This has been clearly illustrated in Fig. 6 of the drawings, by reference to which the method of making a bellcrown hat-frame will be readily understood.

It will be observed from the foregoingthat the machine of my invention is capable of being utilized in the manufacture of hat-frames of different sizes and shapes. The device is simple in construction and may be operated without the exercise of great skill. The blocks or bracket members 20 at the upper ends of the arms 19 of the stretching members might be dispensed with by simply forming exterior grooves in the upper ends of said arms 19; but the construction herein shown and describedis greatly to be preferred, for the reason that said blocks may be made of such a size that when spaced apart to the limit of the machine the distance between them will not be excessive. Hence by giving to said blocks the proper curvature or conformation the crownwire will retain its smooth curvature and will be held with a degree of firmness which enables the rib-wires to be twisted around it without drawing it out of shape. Again, the said blocks form a convenient support upon which the crownwire which is to be operated upon may be readily placed before distending the arms 19, so that the wire will naturally fall into engagement with the grooves 22 without being guided by the hand of the operator, which is obviously a greatconvenience and one which will result in considerable saving of time.
