MORRIS YAEGER, 0F PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO CROWN MANU- FACTURING COMPANY, A CORPORATION OF CONNECTICUT.

MACHINE FOR MAKING WIRE HAT-FRAMES.

Application filed November 20, 1908.

Specification of Letters Patent.

To all whom it may concern:

Be it known that I, MORRIS YAEGER, a citizen of the United States, and a resident of the city and county of Philadelphia, State of Pennsylvania, have invented an Improvement 'in Machines for Making Wire Hat- Frames, of which the following is a. specification. I

My invention has reference to machines for making wire hat-frames and consists of certain improvements which are fully set forth in the following specification and shown in the accompanying drawings which form a part thereof.

The object of my invention is to provide a construction of machine which may be quickly adjusted to various shapes of hatframes, and which will offer very little interference with the hand manipulation of twisting the wires during the formation of the hat-frame.

My object is also to so construct the machine that the hat-frame may be quickly andeasily removed.

The construction employed in my invention, aside from simplicity and cheapness,

. is such as to enable an operator vto produce a large number of hat-frames in a given time.

More specifically, my invention consists of a base, combined with a head pivoted thereto, a series of upwardly extending arms pivoted to the head and each having at its up-' per end a radial bar having a series of ver-- tical holes and a plurality of clamping devices therefor, and a plurality of wires clamped in theholes of the bars and provided with notches adjacent to their upper ends; further in the above structure when further combined with a spreader plate carried bythe base and acting upon the pivoted arms above their pivotsto spread the arms relatively to each other, and a hand operated lever to operate the spreader plate; further in the above specified constructions when provided with a central crown guide adjustably supported centrally of the series of radial bars.

My invention also comprehends other features of construction recited in the claims which, together with those above specified, will be better understood by reference to the drawings, in which:

Figure l'is a plan View of a wire hat frame making machine embodying my invention; Fig. 2 is a sectional elevation of the same; Fig. 3 is an elevation of a part of the machine showing the means for spreading the pivoted arms; Fig. 4: is a plan view of one of the radial bars; Fig. 5 is a cross section of the same; and Fig. 6 is a perspective of one of the notched guide wires.

A is a base plate and may be screwed upon a table or pedestal and has'an upwardly extending cylindrical bearing upon which the head B is sleeved so as tobe capable of rotating about a vertical axis. The lower part of the head B is inwardly flanged and locked in position upon the base Abya flanged bushing A screwed into the base and extending over the flanged part of the head. The head B is slotted about its outerpart to receive the lower portions of the pivoted arms C, which are pivoted at C and held in position upon the head B by a cap plate 5. It is immaterial as to the particular manner of pivoting of these arms C. The lower parts of the arms, below the pivots, are recessed and support coiled springs D which operate upon the pivoted arms so as to throw their upper or free ends toward each other and toward the vertical center line of w the machine. There are 8 of these arms C shown, but more or less maybe employed, as preferred, and

they are so arranged as to move radially,

whereby they approach each other or spread under adjustment. The springs D cause them to approach each'other at their upper a circular spreader plate G which has its perimeter arranged to co-act with the arms IC above their pivots and which, when depressed, causes the arms to spread. This operation will be clearly understood by reference to Fig. 2, in which it will be seen that the arms G extend upward for a short distance and then curve outwardly so as to form cam surfacesv against which i the spreader plate G presses. This spreader plate G is guided upon a central tubular rod R, which is screwed into the bushing A of the base plate A so that it is centered between-the series of arms. H is a hand lever and is pivoted at one end to the head B and has a midpawl H adapted to catch under a lug H? (Fig. 3) when the spreader plate G is depressed, to bring the arms G in the operative position for making of a wire hat frame.

When the hat frame is completed, the locking pawl H is released and the springs D oscillate the arms C to bring their upper ends together to release the wire hat frame. While I have arranged the spreader plate G above the head B, it may be otherwise arranged to operate upon the arms C. The said spreaderplate G is sustained in the position indicated by the arms C under the infiuence of the springs D, and when in this position the arms are in spread condition for the making of the hat frame. When the locking pawl H is released, then the spreader plate G is raised by the approaching arms C under the action of the springs D.

The upper ends or heads C of the pivoted arms G are provided with radial bars J which are adjustably clamped in position so as to extend radially outward. These bars J are preferably inverted L shaped in cross section and have a sliding horizontal connection at J with the upper part or heads 0 of the arms C; they are clamped to the arms G by clamping screws L extending through slots L in the heads C, and in this manner are adjustable radially upon the arms to suit hats of extremes in diameter, whether of the crown or of the rim. The clamping means between the arms C and their radial bars J may be otherwise formed if so desired.

The bars J have their vertical flange clamped to the heads C of the arms C and have their horizontal flange provided with a series of holes I arranged in a line along the length of the bar and preferably also with an extra hole I at its inner end. These holes are provided with screw threaded holes opening into them adapted for reception of clamping screws I of which there may be any number, but ordinarily one for each of the notched wires Y to be clamped in position in the holes. The wires K are preferably made with a flattened side K (Fig. 6)

against which the clamping screws I operate for insuring their being held in the proper position to have their hooked or notched portions K directed outwardly. These wires are preferably straight and may be made in three or more lengths as will be evident from Fig. 2. The upper ends of the wires are flattened and notched at K as clearly shown in Figs. 5 and 6. The wires K placed in the lateral holes I are those for forming the lower circle of the crown.

the arms C are kept comparatively clear so that the binding wires may be easily twisted about the circular wires held by the notched wire guides K because of space for the hands and wires between the arms and bars during such operations. 1 The structure of the machine is simple and desirable and is easily adjusted. 'F or readily determining the size of the rim or hat to be made, the bars J may be provided with scales N as shown in Fig. 4. To change the diameter or size of the crown without changing the desired design or the wires I I in the holes of the bars J, the bars J may be adjusted on the heads 0 of the arms C by means of the screws L. While I prefer the construction shownas excellently adapted for the'commercial embodiment of my invention, I do not restrict myself to the details as these may be'modified without departing from the spirit of the invention. 7
