HAT-FRAME-FORMING DEVICE.

Specification of Letters Patent.

Patented March 10, 1908.

To all whom 'it may concern:

Be it known that I, JULIUs NATTENHEI- MER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Hat-Frame-Forming Devices, of which the following is a specification.

My invention relates to hat frame forming devices and has for its object improvement in such devices.

In the accompanying drawings, Figure 1 is a sectional elevation; Fig. 2 is a plan; Fig. 3 is a detail of the ordinary clamping joint; Fig. 4 is a detail of a clamping joint used in part of the device for permitting one or more of the hook supporting standards to be moved from and returned to a definite position; Fig. 5 is a face view of Fig. 4 with nut and washer removed; Fig. 6 is a section on line 6 6 of Fig. 5 5 Fig. 7 is an elevation of the removable cap used in making high crowned hats; Fig. 8 is a plan oi' the same; Fig. 9 is a partial enlarged section of the lower cup or collar and its connected parts. Fig. 10 is a plan of the same Fig. 1 l is a perspective view of one of the bolts used; and Fig. l2 is a plan of one of the upper collars.

In said drawings, A is a base furnishing a socket for supporting the central standard A which carries the dierent parts of the device and which freely rotates in its base. A convenient means for ermitting such rotation is to secure to the ower end of the rod or standard A a collar A2 providedl with a circular groove A3 which is engaged by a screw A4 in the base A. The groove and screw permit the collar and its standard to rotate, while at the same time preventing the collar and standard from being withdrawn from the base until released.

Mounted on the rod or standard A is a cup-shaped collar or support B which may be secured at any desired position by means of a set screw B. On the collar B are secured by -set screws B4 a series of brackets B2 to each of which is pivoted at B3 an arm C havin a slot C. Secured to each arm C is a secon ary arm or bracket C2 which projects inward and has a depending portion C3 adapted to be engaged by a cup D vertically slidable .on the standard A. These parts are so arranged that when the cup Dis clear 4of the downwardly projecting parts C5, the arms C may be lifted from their normally horizontal position by causing them to turn on their pivots, but when the cup D engages the projections Ca all of the arms C are held in their horizontal position. Also, on the standard A are two other collars or supports E having lugs E6 to which are pivoted the slotted arms or levers E. These supports are likewise held to the standard A by suitable set screws E7 (Fig. 12) so that each may be independently adjustable on said standard. The arms E have depending portions E2 which are engaged by the cups D and D2 in the same way that the cup Dv engages the depending portions C3. Secured to the arms E', by screw E3 passing through the slots in said arms, are other arms E4 provided with notches E5 in their ends. The notches E5 are a little larger in their inner portions than they are at their openings, the object being to decrease the liability of a wire slippin out of a notch after once being placed therein.

It will be apparent from the construction shown that the screws E3 and the slots in the arms E permit of a wide range of adjustment of the arms E4, and consequently of their notches E5. It will be also apparent that when the cups D and D2 engage their respective projections E2 the arms E and E4 are held so as to keep the notches E5 at a iiXed position, but that when the cups are moved downward so as to clear the projections E2 the arms may be moved on the pivoting connection with the collars E.

Slotted hook-supporting standards F are secured to the arms C by bolts C9 which pass through the slots C and F. Nuts C8 or C80 and suitable washers serve to clamp C and F together at any desired adjustment. To prevent the bolts C9 from turning when the nut C8 or C80 is screwed up, a part of the inner face of the bolt head is cut away so that the central part projects into the slot in C as shown in Fig. 3. On part of the arms C, three or more of them, the connection between C and F is made as shown in Figs. 4, 5 and 6. In this case a washer C4 is inserted between C and F, which washer has a short tongue C5 and which has beveled sides engaging the inner faces of the slot E. A second washer C6 and a spring C7 are then interposed between the standard F and the nut C5. As thus made the tension ofthe spring C7 acts to hold the standard F at any angular adjustment in relationship to the arm C. But the bevel on the side of the .tongue C5 and the compressibility of thespring' C7 permit the standard F to be turned on the bolt C9 as a pivot. The washer C4 is prevented from turning either by reason of a large diameter 5 which makes its frictional contact with the arm C at a long radius from the pivot or by reason of any other suitable construction. As a consequence of this, after the standard F has been moved by hand from its adjustment it may be readily returned to its original position without the necessity of going through the process of adjusting the position of the standard F each time that it is desirable to move it. The object of this will appear later.

Mounted on each of the standards F are a group of slotted bars G provided with hooks G on one end. These bars are held at any desired adjustments by bolts C9 and nuts in the same manner as explained for the ordinary connection between arms C and standards F. Knurled-thumb nuts C80 are shown for the connections between C and F, and common hex-nuts C8 for the connections between F and G, but this difference is immaterial and either may be used at all places. Secured at a convenient place on the standard A is a bracket H to which is pivoted a lever H. Connected to the inner end of the lever H is a rod H2 which is parallel with the standard A and passes up through the cups D, D and D2. Set screws H3 serve to connect these cups to the rod H2, and also serve to permit each cup to be independently adjustable to correspond to the adjustment given to the supports B and E. In the normal position of the arms C and E the projections C3 and E2 are in condition to be locked by engagement with their respective locking-cups D, D and D2. It will `be apparent that by connecting these cups to the rod H2 a simple movement of the lever H by hand will serve to lock or unlock all of these arms. It will also be apparent that by loosening the set screw H3 in the cup D, the cup may be freed from connection with the lever H and may be operated independently by hand. An adjustable set collar J is located on the standard A so that the cup B and connected parts may be lowered from and restored to a desired adjustment without requiring a new adjustment each time such lowering takes place. In using the device it is sometimes desirable to adjust part of the hooks G so that they are higher than the notches E5, and are also nearer to the center than are those notches.

The process of forming hat-frames by winding wire so as to be held by a series of 60 notches and hooks is well known in the art and need not be described here. During the forming process the cups D, D and D2 are in their locking position so that the hooks and notches will be irmly held at their desired adjustment, but `when the completed hatframe is to be removed the arms C and Ey are unlocked so that the hooks and notches may freely move inward to facilitate such removal. This inward movement is made possible by normally moving the arms C and E on their respective pivots. In the forming process the collar B and the parts con nected thereto are usually lowered so that wire may be placed readily in the notches E5. The outer parts are then restored to their desired adjustment against the collar J and the remainder of the hat-frame formed by placing wire in the notches G. This lowering of the outer parts may be accomplished by releasing the set screw B and also by releasing the set screw H3 in the cup D so that that cup may be free from the rod H2 to permit said lowering. That the inwardly projecting hooks G may clear the ends of the arms E4, the oint connection between C 35 and F is made as shown in Figs. 4t to 6 and as previously described. This permits this particular inwardly adjusted group of hooks G to be swung outward, the frame work snpporting all of the hooks G to be lowered, and then the shifted group of hooks to be again returned to desired position without further adjustment. Usually not more than two or three of the standards F require such shifting of position, but in case it is wanted on more of them, the joint shown in Figs. 4 to or any similar joint, may be placed on more or even all of the arms C.

In the hat-frame machine as thus dcscribed, it will be seen that the wire-holding members G and E4, are divided into three sets or groups according as they are supported on one or the other of the supports B or E. Also that each set is vertically adjustable on the standard A and independently of the adjustment of any of the other sets. And further, that the locking cups D, D and D2 are adjustable on the rod H2 so that they may correspond in position with supporting devices on the standard A, or they mav be released from that rod and be man ually operated independently of each other.

In Figs. 7 and 8 is shown a removable cap block (shown in dotted lines of Fig. 1) which is used in making hats with high or domeshaped crowns. This block is simply a circular dome-shaped piece M which is centrally held on the top of the device either by a socket M arranged to engage the top of the standard A, or by any other convenient 12C means. Running over the dome of the block M are a series of wire grooves M2 which correspond in number and arrangement to the arms E4.

Having thus described my invention, what I claim as new and desire covered by Letters Iatent is:

1. In a hat-frame forming device, a central standard, a plurality of collars secured at different elevations on said standard, a series of independently movable arms ypivoted to each collar, and a se arate locking device for the arms of each co ar.

2. In a hat-frame forming device, a central standard, a plurality of independently adjustable arm-holding devices secured at different elevations on said standard, a series of arms pivoted to each such holding device, and a separate locking device for each series of arms.

3. In a hat-frame machine, a central standard, a plurality of series of pivoted arms carried by said standard, a separate locking device for each series of arms, and connections between said locking devices whereby they may be simultaneously operated.

4. In a hat-frame machine, a central standard, a plurality ofseries of pivoted arms carried by said standard, means whereby said series of arms may be independently adjusted, a locking device for each series also independently adjustable, and connections by which said locking devices may be simultaneously operated.

5. In ahat-frame machine, a central standard, a plurality of sets of pivoted arms supported at diierent elevations on said standn ard, means by which the support for each set is independently adjustable on said standard, a separate locking device for each set of arms, a pivoted lever, and a rod extending from said lever to said locking devices whereby said locking devices may be simultaneously operated.

6. In a hat frame machine, the combination with a central standard, and members for holding wire during the hat forming process, a division of said members into sets, a further division of one of said sets into groups, means by which any set may be adjusted in position independently of the other sets, and further means by which any group, may be adjusted independently of the other groups vand the other sets.

7. In a hat-frame machine, the combination with a central standard, and wire-holding members, of a plurality of devices mounted upon said standard one above another and each arranged to support a plurality oi said wire-holding members, and means by which said supporting devices are independently adjustab e in a vertical direction on said central standard.

8. In a hat-frame machine, the combination with a central standard, of an adjustable supporting device mounted upon said standard, a series of radial arms pivoted to the supporting device, wire-holding members adjustably supported on said arms, and other wire holding members independently supported from said standard and normally located at a less radius than the before men? spect to each other, of spring actuated means for permitting a desired group of said hooks to be independently moved from and returned to their normal adjustment with respect to the other groups.

11. In a hat-frame machine, a series of wire-holding members located about a center, a second series of wire-holding members surrounding the first series, a division of the second series of wire-holding members into groups, means by which each'group may be shifted from its normal adjustment and upon being returned will automatically be stopped and held at its previous adjustment, and means by which the groups may be collectvely lowered from and returned to a previous position independently of the inner series of members.

12. In a hat-frame machine, a series of wire-holding members located about a center, a second series of wire-holding members surrounding the first series, and means by which the outer series may be lowered from and returned to an adjusted position independent of the inner series so as to facilitate the placing of wire on said inner series.

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