Y.

Application March 2, 1948, Serial No. 12,652

Claims. (o1. 22-3-22) This invention relates to hat leather or sweat band trimming machines wherein the bands are folded over a pin and. both ends cut at the same time, and in particular a hat leather trimming machine for bands having reeds in the edges thereof wherein it is desired to trim the leather with the reed projecting at the end.

The purpose of this invention is to provide means for trimming hat leathers having reeds therein without cutting the reeds.

This invention is animprovement over the hat leather trimming machine in my Patent Number 2,118,278, in that a notch is provided in the knife and means is provided for adjusting the position of the knife and band holding elements so that the notch registers with a reed in a band positioned to be cut b the knife.

In the usual trimming machines for this purpose the leather bands are placed over a pin that is adjustably mounted on a panel and the panel is pivotally mounted on a base plate at a far corner thereof. This arrangement permits very little adjustment and for this reason the panel of this invention is pivoted at the center whereby the band may readily be moved over a relatively large angle range.

In these machines considerable time is lost in throwing the knife handle all of the Way over to a position of rest and to overcome this objection this machine contemplates a handle mounting including a collar having a flat side and a tooth with a spring coacting with the fiat side to friotionally hold the handle and with the end of the spring positioned to stop and hold the handle justover the center by engaging the tooth wherein the handle will be held substantially upright while a leather is being positioned in the machine.

This invention also includes improvements in the construction and arrangement of the parts wherein the machine operates more efiiciently and wear in the parts is reduced to a minimum.

Machines of this type are also subjected to considerable abuse particularly from inexperienced workmen and for this reason the parts are of rugged and at the same time open construction wherein the; operating instrumentalitiesarenct easily damaged, and may readily be removed and repaired orreplaced.

In: the hatindustry it is often diflicult to obtain experienced operators and with this thought in mind'this invention provides hat size indicators and other adjusting gages in convenient positions so that there is very little excuse for making mistakes.

The object of this invention is, therefore, to provide an improved hat leather trimming machine that cuts bands with reeds projecting therefrom in which the parts are readily adjustable.

Another object of the invention is to provide a hat leather trimming machine wherein the movement of the knife to different positions to compensate for bands of different sizes and styles is synchronized with the movement of the leather carrying panel or table.

Another object of the invention is to provide means for adjusting the position of the knife with the knife maintained in alignment with a stationary shear blade.

A further object of the invention :is to provide an improved hat leather trimming machine for cutting leathers having reeds therein which is of a simple and economical construction.

With these and other objects and advantages in view the invention embodies a horizontally disposed base plate or table, a hat leather mounting panel pivotally mounted on the base plate, means adjustably positioning the leather on the panel, a knife, having a notch therein, pivotally mounted on the said base plate through a sliding bracket which is linked to the panel, means adjusting the position of the bracket and panel, and a leather holding clamp coacting with the knife.

Other features and advantages of the invention will appear from the following description taken in connection with the drawings, wherein:

Figure I is a plan view of the improved hat leather trimming machine with a leather band indicated thereon in dotted lines.

Figure 2 is a view showing an end elevation of the machine.

Figure 3. is a view looking toward the end of the knife mounting bracket taken on line 33 of Figure 1, with parts omitted.

Figure 7 is a detail looking toward the end of the knife mounting bracket, with parts omitted and parts in section, showing the spring and tooth for holding the knife.

' Referring now to the drawings wherein like reference characters parts the improved hat leather trimming machine of this invention includes a base plate ID, a slidablepanel II, a bearing bracket l2, and a knife [3.

The base plate :6 is mounted on posts l4 and at one end is a knurled shear plate l5 that is positioned to coact with the knife I3 which is mounted on a bar l6 having a handle 1- on the outer end. The bar [6 is mounted on a shaft 18 that is journaled in bearings I9, 20, and 21 of the bracket [2 and the cutting edge of the knife is resiliently urged toward the edge of the shear plate [5 by a spring 22 positioned between the bearing 26 and a collar 23 on the shaft. A gripping plate 24 is carried by an arm 25 which is indicate corresponding 4 the panel is adjusted for hat leathers of different sizes whereby with the distance from the pivotally mounted on the shaft I8 and the outer end of the arm is held in a bracket 26 on the back of the bar l6 of the knife. The bracket 26 is provided with a spring 21 that resiliently holds the plate 24 so that it presses downward firmly holding the ends of a band 28 on the shear plate 15. The outer'end of the shaft I8 is provided with a collar 29 having a flat side 30 and a tooth 3| and with a spring 32 positioned on a block 33 on the bracket bearing against the flat surface the knife will be resiliently held, as shown in Figure 7, and when the knife is raised to a position just over the center, as indicated by the dotted lines in Figure '7, the tooth 3| will 7 with a slot 34 by which it is slidably mounted on a key 35 positioned in the base plate [0, as shown in Figure 3 so that the bearings on the bracket will be held perpendicular to the end face of the base plate, and the position of the bracket may readily be adjusted by a thumb screw 36, which extends through an opening in a bearing 31 at the edge of the base plate, as shown in Figure 6. The screw is held between

collars

38 and 39 and with the end threaded in a lug 40 on the bracket the position of the bracket may readily be adjusted by turning the screw. The bracket 12 is clamped to the base plate In by a wing nut 4| on a stud 42 that extends through a slot 43 therein, and the inner edge of the bracket is attached to the panel H by a link 44, as shown in Figures 1 and 6.

One end of the link 44 is connected by a screw 45 which extends through an unthreaded opening in the link and is threaded into the bracket I2, to the bracket and the other end by a screw 46 which extends through an unthreaded opening in the link and is threaded into the panel II to the panel, and with the under side of the link provided with a shoulder 41 which is parallel to and abuts the edge of the bracket I2, the link will draw the panel with the bracket so that with the band 28 on the pin 48 and the edge in which the reed is provided positioned against the block 49 on the panel the reed will register with a notch 50 in the knife. In adjusting the parts the screw 46 travels on a radius from the center of the pin .51 and owing to the length of.

the radius the pin travels substantially in a straight line whereby it is essential that the shoulder 41 hold the link 44 in the angular position shown in Figure 1. By this means the material of the band may be cut around the reed and the reed will extend through the notch.

With the panel connected to the bracket in this manner the bracket follows the panel as notch in the cutting edge of the knife to the pivotal mounting of the knife in the bracket constant, the reed of a hat leather positioned against the block 49 will always register with the notch in the knife so that the knife will cut the leather Without cutting the reed.

The panel H is pivotally mounted on a centrally disposed pin 5| and one side thereof is provided with an arcuate slot 52 through which it may be clamped in adjusted positions by a thumb screw 53. The lower corner 54 is positioned to register with graduations 55 on the base plate so that the position thereof may readily be determined.

The hat leather holding pin 48 is pivotally mounted on a block 56 by a thumb screw 51 in a slot 58 and the block 56 is slidably mounted on a bar 59 on which it is held by a thumb screw 66 in a slot 6|. The block 56 is provided with an indicating mark 62 that registers with grad uations 63 on the panel to facilitate setting the position of the pin, and the bar 59 is slidably held in a head 64 on the far end of the panel. The head 64 is positioned over a post 65 on which is a gear 66 that meshes with a rack 61 onthe bar 59 and it will be noted that by turning the post the bar may be slid inward and outward to adjust the pins 48 to different hat sizes as indicated by the numerals 68 on the surface 'of the head. The upper end of the post 65 is 7 provided with an eccentrically positioned hub 69 and a ring 16 is pivotally mounted thereon by pins H and 12, as shown in Figures 4 and 5. A handle 13 is mounted on the ring through a. rod 14 and the handle is provided with a pointer which is positioned to register with the hat sizes 68 on the upper surface of the head. The rod 14 is urged downward into notches 16 in the upper edge of a plate 11 by a spring 18 that is held on the upper end of the hub 69 by a screw 19. The rod 14 extends through a slot 86 in the face of the head, as shown in Figure 4.

In addition to the spring 32 a bracket 8| may be provided on the upper surface of the bar l6.

as shown in Figures 1 and 2, and the bracket is provided with a projection 82 that extends over to contact the upper surface of the base plate l0 when the handle is upright and'just over the center, to insure the handle and knife being held upright should the spring 32 slip off of the collar 29 or break. 7

With the parts arranged in this manner the hat leather or sweat band 28 may be positioned on the panel II and with the ends of the band adjusted by the left hand the knife may be ac-- tuated by the right hand so that the ends of the band may be cut with the reeds extending therefrom, and with the parts adjustably held the bands may be accurately positioned so that they may be cut to exact measurements.

It will be understood that modifications may be made in the design and arrangement of the parts without departing from the spirit of the invention.
