MACHINE FOR MAKING HAT-FRAMES.

Specification of Letters Patent.

Patented Dec. 12, 19 11.

Application filed September28, 1910. Serial No. 584,234.

To all whom it may concern:

Be it known that we, HARRY SILBERT, of

' Boston, inthe county of Suffolk, and SIDNEY WACHTEL, of Brookline, in the county of Norfolk, both in the State of Massachusetts, have invented certain new and useful Improvements in Machines for Making Hat- Frames, of which the following is a specifica'tion. i

This invention relates to machines for making wire frames for ladies hats and refers particularly to that type of such machines which employ a circular series of groups of ad]ustable pattern-forming rods or arms around Wh1ch the operator wraps or winds the wire, a machine of this general type beingillustrated in U. S. Letters Patent N0. 97 2,407 granted to us Oct. 11, 1910.

One of the objects of the present invention is to provide a machine of this character having improved mechanism for controlling the radial movements of the members or units of the circular form.

Another object is to provide a machine of i different sizes of hats, without altering their 1 is formed with an angular recess 18 in its details of construction tending to facilitate.

the operation of making the hat frames, all

as will be more fully hereinafter pointed out.

To these-ends the invention consists in the construction and Combination of parts substantially as hereinafter described and pointed out in the claims.

Of the accompanying drawings :Figure 1 is a plan view of the machine. Fig. 2 represents a section on line 22of Fig. 1. Fig. 3 represents a section on line 3-3 of Fig. 2, but with the table and its angular stud removed. Fig. 4: is an under plan view of the rotary form, removed from the supporting spindle. Fig. 5 is a perspective view of one of the form units, consisting of a clamp box and a set of wire-supporting arms. Fig. 6 is a detail elevation, looking from the line 66 of Fig. 1. Fig. 7 is'a detail view of the size-regulating pin or spindle.

Similar reference characters indicate the same or similar parts in all of the views.

A standard 10, having a base or foot piece -or other support, is provided with a spindle 12 on which the entire mechanism is adapted to rotate freely to enable the operator to turn it around as the hat frame is being a made. This free rotation, however, is, in the present machine, limited to one direction, rotation in the other direction being restricted and utilized to collapse the circular series of form units so that the operator can remove the finished hat frame.

Surrounding the spindle 12 and secured thereto as by a screw 13, is a circular block having a ratchet-toothed upper surface 14. Said block is rigid with the standard and therefore might have been made integral therewith. It is made as a separate piece for convenience of manufacture, but it really constitutes the upper section of a two-part standard. The ratchet 14 is circular andthe surface 15 within the ratchet is raised to provide a flat bearing to rotatively support a block 16 which has one or more gravity pawls 17 pivoted to it and engaging the ratchet 1 1. Therefore the block 16 can rotate freely in but one direction. Said block upper side (see Fig. 3 and dotted lines in Fig. 2) for a purpose presently described.

The table 19 and its arms 20 constitute a carrier for the series of arm clamps and is provided with a wide pinion 21 at the center of its under side, said pinion being secured to the table by a screw 22 and washer 23. Rigidly connected to or integral with the pinion 21 is a downwardly projecting angular stud 24fitting the recess 18 of block 16 and having a central aperture for the spindle 12.

Each arm 20 is formed with slide-ways 25 for a frame or box 26.' The slide-ways are practically ribs fitting grooves 27 formed in the sides of the boxes 26 near the tops of the latter (see Figs. 5 and 6) so that the boxes practically depend from the arms instead of rising above the arms as in our patent above mentioned. We have found that this structure enables the boxes to slide easier and with less liability of friction or binding than in the structure shown in said patent. The internal form of the boxes is substantially the same as in the said patent, and the same is true of the adjustable wire-supporting fiat arms or strips 28 having shoulders 29, and formed with wire-engaging notches 30. Also as to the clamping plates 31 and screws 32. The adjustments and functions of said wiresupporting arms 28 are fully described in said patent.

Each box 26 is formed with an arm toothed at one side of its inner end to form a rack 33 which engages the pinion 21. These rack arms are not all in one plane, but are in different planes as shown in Fig. 2 so that they (eight of them being preferably employed in practice) may overlap and all engage the one pinion as shown in Fig. 4. The boxes and their guide-ways and the rack arms are a little to one side of and parallel with lines radial to the axis of the pinion, so that the racks shall be tangent to the pinion and preferably in line with the longitudinal center of the boxes so that as the boxes move in their ways as presently described they will slide freely without lateral binding. To hold the boxes and their groups of arms 28 in their outermost positions during the operation of making a hat-frame, we employ springs 34 (four being shown in Fig. 4) each spring being connected at one end to a screw or pin 35 projecting from a table arm 20 and at the other end to a screw or pin 36 projecting from the box mounted in that arm.

During the operation of making a hat frame, the carrier and its groups of arms 28 which as a whole constitute the pattern or form for the hat frame, may be freely rotated in the direction which carries the pawls 17 idly over the circular ratchet 14. A slight turn of the carrier in the other direction however instantly draws the boxes toward the center so as to collapse the form to enable the finished hat frame to be removed without changing the adjustment of the arms 28. This action is due to the fact that when said carrier is turned as described, the pawls 17 hold the block 16 stationary, and the angular recess of the latter which receives the angular stud of the pinion 21 prevents the latter from turning. But since the carrier can turn on screw 21, and as the boxes move therewith, such turning of the carrier in what may be termed the reversing or form-collapsing direction, must swing the racks 33 slightly around the now stationary pinion so as to simultaneously draw all the boxes inward against the tension of the springs 34. This can be done with one hand, the other hand being em ployed to remove the finished hat frame, after which, release of the table permits the springs to act to turn the table and return all boxes to their outer positions.

For several purposes, it is desirable that the hat frames shall be made in different sizes, an important reason being so that the frames can be nested for shipment. For this purpose, the difference in sizes need be only slight, but it is of course essential that the differences shall be uniform. lVe will now describe the mechanism for this purpose.

Rotatably mounted in the outer end of one of the boxes 26, is a pin 37, having its outer end enlarged as best shown in Fig. 7, said pin having a somewhat smaller portion 38 mounted in a suitable bearing, formed in the outer end of a clamp box 26. The inner end of the pin is formed with an annular recess or groove 39. A screw 40, (see Fig. 4) passes through a threaded opening in one side of the box, the inner end of said screw entering the groove 39, so as to lock the pin against removal. Said screw, when turned in so that its inner end will bind against the bottom of groove 39, will lock the pin in its rotatably adjusted position, the object of such adjustment being presently described. The barrel, or larger portion of the pin is formed with a plurality of notches 41, the bottoms of which are preferably flat, forming chords of the circular surface of the barrel portion of the pin. The notches are formed at different distances lengthwise of the pin, and in different portions of the periphery thereof, so that when said pin is rotatably adjusted, either one of said notches will, alone cooperate with the positive lock. Said lock consists of a sliding plate 42, having horizontal slots through which guide pins or screws 43 pass. Said pins or screws are mounted in down-turned ends 44 of the slide-ways. (See Fig. 4.) A spring 45 attached to one of the slideways bears against one end of the plate 42, to hold said plate normally in the position shown in Figs. 1, 4 and 6. Said plate has an opening 46 surrounding the enlarged portion of the pin 37, one side of said opening 46 being pref erably formed as a chord of a circle, as indicated by dotted lines in Fig. 6. This last mentioned portion of the plate 42 constitutes a latch 47 which is adapted to cooperate with either one of the notches 41 to positively look all of the clamp boxes 26 against movement in either direction as will be presently described. One end of the plate 42 is bent outwardly to form a finger-piece 48. The outer end of the pin 37 is preferably milled as at 49.

WVhenever a change is to be effected in the size of hat frame to be made, the op erator pushes against the finger-piece 48 so as to release the latch 47 from the one engaged, and further movement in the same direction will rotate the table or carrier so that the cooperation of the pinion and the racks hereinbefore described will result in collapsing the entire form consisting of the 41 opposite the latch or stop 47, and the plate 42 then released, the springs 34, act through the connections and the pinion and racks as hereinbefore described, to cause the carrier,

to rotate backwardly until the latch or stop 47 slips into the selected notch 41, the spring 45 then holding the plate42 in looking position. Owing to the engagement of the latch or stop portion 47 of the plate 42, with one of the notches 41, there can be no movement of the clamp boxes along their ways. Consequently, all of the clamp units are held:

positively and firmly against inward movement during the operation of wrapping the wires of the hat frame around the arms 28.

When a hat frame is completed, and is to.

ing the entire carrier so as to collapse the form to permit the removal of the finished hat frame. If no change is to be effected in the size of the frame being made, the operator will not touch the pin 37. When he lets go of the finger-piece 48, the lock members will be automatically reengaged as the table or carrier springs back under the action of the springs 34.

It will now be understood that we have provided not only means for definitely fixing the sizes for the making of the hat frame, but also that the action of shifting the clamp units inwardly and outwardly is obtained without the employment of any lever mechanism.

The machine comprises a series of groups of wire supporting arms which are movable to enable the hat frame to be released without liability of bending the arms out of shape when taking the hat frame ofi from the machine. Also the mechanism automatically returns the wire supporting arms to proper position, ready for the making of the next frame.

While the series of clamps may be referred to as circular, and is so referred to herein and in the claims, it is to be under stood that this term is employed for purposes of brevity in description and not of limitation. The term is not to be understood as limiting us to arranging the clamps in a perfect circle, because although most hat frames are circular yet it would be no departure from our invention to have the clamp frames arranged in more or less of an oval or ovoid. Of course, by changing the outward inclination of the arms of some groups relatively to the arms of other groups the construction as illustrated may be used for making hat frames which are not exactly circular.
