HAT-BRIM TRIMMER.

SPECIFICATION forming part of Letters Patent No. 660,861, dated. October 30, 190k).

. Application filed May 21, 1900. Serial No. 17,438. (No model- T0 at whom it may concern:

Be it known that we, MYERLEVY and AU- GUST KINDERMANN, citizens of the United States of America, and residents of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Machines for Cutting, Rounding, and Trimming Hats, Metal and other Patterns, Shoe-Qoles, and the Like, of I which the following is a specification.

This invention relates to certain improvements in machines for trimming the edges of hat-bodies and other articles having raw or irregular edges; and the object of the invention is to provide a machine of this character of a simple and inexpensive nature which shall be adapted for use in trimming the raw edges of articles of various forms or shapes in a rapid and uniform manner.

The invention consists in certain novel features of the construction, combination, and arrangement of the several parts of the improved edge-trimming machine whereby certain important advantages are attained and the machineis made'simpler and cheaper and is otherwise better adapted and more conven ient for use, all as will be hereinafter fully set forth.

The novel features of the invention will be carefully defined in the claims.

In the accompanyingdrawings, which serve to illustrate our invention, Figure 1 is a side elevation showing a machine constructed according to on r invention. plan view of the machine. Fig. 3 is an enlarged partial section showing the edge trimming and feeding devices, the section being taken length wise through the cutter-carrying sleeve. Fig. 4 is 'an enlarged partial front view showing the arrangement of the edgetrimming, feeding, and guiding means; and Fig. 5 is an enlarged partial plan showing the same parts. Fig. 6 is an enlarged detail view showing one of the work-holding devices carried by the pattern. Fig. 7 is a View drawn to a smaller scale and showing aform of worksupporting device especially adapted for use in connection with hat-bodies or the like having curled or upturned brims. Fig. 8 is a detail view drawn to a larger scale and showing certain features of the work-supporting Fig. 2 is a partial trimming and feeding devices, the guide wheel arm being shown in raised position. Fig. 10 is an enlarged partial side View showing the means for locking the guide-wheel arm when in lowered position forvholding the pattern drawn over toward'the cutter. Fig. 11 is a front view showing the work-rest, the upper part of which is shown in section to illustrate the means for holding the rotating portion of the work-plate thereon. Fig. 12 is an enlarged partial section taken through the work-rest in substantially the plane indicated by the line .9 sin Fig. 11 and showing the means to limit the upward movement of the upper part of the work-rest.

In the'views, 1 indicates a table or base, and 2 a standard extended above the same and provided with abearing in which is journaled a sleeve 3, having collars 4 al: to hold it against endwis e movement. The upper end of the standard above the bearing for sleeve 3 is bent or curved laterally and downward, as shown at 5, to provide another bearing 6 for the forward end of the sleeve 3. On the central part of the sleeve 3 between its two bearings is secured a sheave or band-wheel 7, grooved to receive a band or belt 8, which extends upward and is driven from'asuitable sourceof power (not shown) in order to impart to the sleeve rotative movement in its bearings. i 4

Within the bore or hollow of the sleeve 3 is held to turn a shaft 9 of greater length than the sleeve, so v that the ends of the shaft project beyond opposite ends of the sleeve, as clearly shown in Fig. 3, the rear end of said shaft, or that end adjacent to standard 2 and toward the right in the drawings, being provided with a grooved sheave 10, adapted to receive a belt or band 11, which also extends upward and is driven from a suitable source of power (not shown) in a manner to impart to shaft 9 rotative movement within the sleeve 3. In the operation of the machine it is desirable, for purposes to be hereinafter explained, to operate the shaft 9 at a different speed relative to the sleeve 3, and this may be accomplished by forming the sheaves '7 and 10 in different diameters, whereby they may be both operated from the same drivingshaft, as will be readily understood.

On the forward end of the sleeve 3, or that end of said sleeve which is adjacent to the bearing 6 and at the left hand in the drawings, is secured a collar or head 12, herein shown as screwed upon the shaft. To the face of the collar 12 is secured, by means of screws 13 or the like, a circular or disk-like cutter let, having a peripheral cutting edge. On the adjacent projecting end of shaft 9 is formed a square 15, whereon is held a feed wheel or disk 16, having a roughened peripheral surface and of less diameter than the cutter 1 t, from which it is slightly spaced apart. To secure the feed-wheel upon the shaft 9, a washer 17, held by a screw 18, engaged with a threaded opening in the shaft, is employed.

Beneath the cutter 14 and feed-wheel 16 is a work-rest 19, having at its upper end a work-plate 20, adapted to support the work in position to be trimmed by the cutter and fed by the feed-wheel. This work-plate 20 is provided with a rotating portion 20, held by a pivot-screw 2O at its center, as clearly shown in Figs. 5 and 11, and so arranged that one side of its upper surface is in position beneath the feed-wheel 16, so as to constitute a movable support for the work to enable it to be readily moved past the cutter and over the work-plate by said feed-wheel. The lower end of the work-rest 19 is formed with a slideplate 21, arranged for movement between undercut guides 22 on the table 1, whereby the work-rest may be moved out from beneath the cutter and feed-wheel to permit of conveniently placing the work in position to be trimmed. A locking device 23 is carried by the plate 21 of work-rest 19 and is adapted for engagement with one of the guides 22 for locking the work-rest against movement when its work-plate is beneath the cutter and feedwheel.

As clearly shown in Figs. 1 and 11, the work-rest 19 is formedin two parts, the upper part having a central tongue 19, depending in a recess or hollow of the lower part and resting on a spring 19, whereby said upper part is supported to hold the work-plate pressed elastically toward the cutter 14 and teed-wheel 16. This means provides a certain degree of spring for the work-plate,whereby ordinary inequalities in thickness or wrinkles and the like in the article being trimmed are permitted to readily pass beneath the feed-wheel. The upper part of the work-rest is also guided on pins 19 at opposite sides of the recess or hollow of the lower part and is provided with screws 19, which by en gagement with slots 19 in the guide'pins 19 serve to limit the upward play of the workplate, whereby the latter is prevented from being pressed upward with the full force of the spring against the cutterand feed-wheel. This construction of the work-rest also permits of conveniently withdrawing the work from beneath the feed-wheel when it is partially, but not completely, trimmed, it being only necessary for this purpose to press the upper elastic portion of the work-rest downward, so as to relieve the work from pressure upward against the feed-wheel.

The work-supporting device is indicated as a whole by 24 on the drawings and is adapted to support the work while the edges thereof are being trimmed. This device will of course be varied according to the nature of the article to be operated on. The device shown in Fig. 1 is designed for supporting hats having fiat brims, such a hat being indicated at w and its brim at 41; on the drawings. The brims of the hat-bodies are ordinarily formed with irregular rough edges, as indicated in Fig. 2, and the function of our improved machine is to trim these rough or irregular edges, so as to give a proper rounded form to the hat-brim.

The supporting device 2 1 (shown in Fig. 1) comprises an arm 25, slotted, as shown at 26, for the passage of a bolt or screw 27, whereby it is adjust-ably held on the under side of the table 1. The outer free end of the arm 25 carries a sleeve 28, held by a set-screw 25, and in which is loosely held the lower reduced end of a stem 29, the upper end of which is made tubular to receive a pin 30, depending from the under side of a rounded plate 31, adapted to fit inside the crown on the hatbody, as shown in Fig. l A screw 29, carried by the stem 29 and playing in a slot 28 of sleeve 28, serves to permit of adjusting the height of the stem 29 to permit of accommodating hat-crowns of different heights. A spring 32 is coiled on the pin 30 beneath the plate 31 and serves to support said plate clastically above the upper end of the stem 29, the strength of the spring being proportioned to the weight of the hat'body and the pattern carried thereby, (and which will be hereinafter referred L0,) so as to permit said hatbody when on the supporting device to fall of its own weight into position with its brim 00 in substantial alinement with the cutter and feed-wheel.

3 1 indicates the pattern, made of sheet metal or the like in a form substantially similar to that of the hat-brim when trimmed and having a central opening, through which the crown of the hat-body is passed up, as shown in Figs. 1 and 2, so as to permit said pattern 34 torest upon the top surface of the hatbrim m. If desired, the pattern may also be cutout for the sake of lightness and economy, as indicated at 34 in Fig. 2. In order to secure the pattern to the hat-body while the hat-brim is being trimmed, we provide a plurality of spring-catches 35, (shown in detail in Fig. 6,) said catches being carried on the pattern and having pointed ends to penetrate the hat crown, so as to hold the pattern against turning movement upon the brim. There may be but one or any desired number of these catches. The pattern 34 is also provided upon its upper face with a raised bead eeosei or track 36, which extends parallel with and a short distanceinside of the edge of the pattern, as clearly shown in Figs. 1 and 2, being adapted to be engaged by a wheel 37, held on an arm'38, extended from the bearing 6 of standard 2. The arm 38 is pivoted at 38 on the bearing 6 and has at its rear end a notch or recess adapted to receive the shank of a headed pin 39 on said hearing when the arm 38 is lowered, as shown in Figs. 1 and 2. Said notched end is also provided with a-slit or kerf 38 to give it sufficient elasticlty to permit of being pushed or sprung over the shank of pin 39 when the arm 38 is raised and lowered. When the arm 38 is raised, as shown in Fig. 9, the wheel 37 is lifted out of engagement with the pattern, and when said arm is lowered to engage the wheel with the pattern the notched end of the arm will by slipping over and engaging on the shank of pin 39 form an effective means for locking it in position. By means of the wheel 37 the pattern 34 and of course the hat body to which said pattern is secured are held drawn over toward the cutter, so as to be in proper relation thereto and to the feed-wheel.

The edge of the pat-tern 34 is adapted to be engaged under the feed-wheel '16, the roughened surface of which acts in the rotation of shaft 9 to draw the edge of the pattern along between the feed-wheel and work-plate 20, said feed-wheel being provided with a coneshaped periphery tapered toward the cutter 14, so as to draw the pattern as closely as possible toward the cutter.

The face of the guide-wheel 37 is, as clearly shown in Fig. 9, made beveled or conical and is adapted for engagement with a bevel or undercut 34", formed in the adjacent side of the head or track 36 and extending part way around the pattern, as shown in Figs. 2 and 9. This undercut serves to prevent the arm 38 from being left unlocked when raised in trimming the edge of a downwardly bent or curled hat-brim, since said undercut, beingformed around such portion of the brim as is bent down, serves to draw the arm 38 down again and lock it on the pin 39 after the downwardly-bent portion of the brim has passed beneath the feed-wheel.

Aguide 40 is provided, carried on the standard and having a flattened and curved end 41 arranged in position to be engaged by the edge of pattern 34 to prevent the same from being drawn too much toward the cutter,

whereby its edges might be engaged and damaged. The work-plate 20 has at one side an extension 42, beneath the end 41 of guide 40, to support the brim and pattern at this point, said extension being spaced away from the guide sufficiently for the passage of the brim, as shown in lg igs. 1, 4, and 9. The end of guide 40, being curved or rounded upwardly and rearwardly, permits the rough or irregular edges of the brim to pass more readily beneath it and over the work-plate 20.

In operation when it is desired to trim the edges ofa hat-body or other article the same is applied to the supporting device, the arm 25 of which is adjusted to suit the width of the brim, so as to permit the projecting rawto press the wheel 37 thereon into engage-- ment with the track or head 36 of the pattern to hold the said pattern and the work to which it is secured drawn over toward the cutter 14 in order that the latter may trim the edges of the work oli neatly around the edges of the pattern. The notched or recessed end of said arm 38 will by engagement with the pin 39 when the arm is in its lowered posit-ion act to hold the wheel 37 securely in position upon the track 36; but the engagement ofsaid end of the arm 38 with said pin 39 is such as to permit the arm to be readily raised by the operator when it is desired to remove the pattern and work for any reason. The sleeve 3 and shaft 9 being now set in motion, it will be obvious that the edges of the hat-brim will be drawn along beneath the cutter by the engagement of the feed-wheel with the pattern 34 and the rough or raw edges of the hat-body will be neatly trimmed along the edge of the pattern, which is held pressed toward the cutter by means of the guidewheel 37. and is held by the guide 40 against excessive movement in that direction in such a manner that the cut or trimmed brim of the hat is made to conform exactly to the edge contour of the pattern. When for any reason it is desiredto remove the hat-body from the machine before it is completely trimmed, this may be accomplished by depressing the upper elastioally-supported portion of the workrest 19.

When the hat-brim 5c is bent down at one or more points, as is sometimes the case, the pattern 34 will be similarly formed, and when such bent portion of the brim comes, in the movement of the pattern and brim, beneath the cutter 14 the spring 32 will act to assist in raising the hat-body, so as to permit the brim and pattern to more readily pass beneath the cutter. When the cutter and feed-wheel are driven at relatively dilferent speeds, a draw out is imparted by the cutter, and an lOJ important advantage is thereby gained in the trimmed; but when hat-bodies having curled or raised brims are to be trimmed the form of the supporting device shown in Figs. 7 and on the reduced end 46 of stem 47 and has its lower end rested on a collar 51 in the sleeve 43, which collar has a threaded pin 52 extended through a slot 53 in the sleeve and adapted to receive a nut 55, whereby the collar may be set at various points in the sleeve, the slot having offsets 54 to facilitate the clamping of the collar in the sleeve. By this means the tension on the spring may be varied at will. The lower end 46 of stem 47 carries a notched rod 56, on which is mounted an adjustable stop 57, adapted by engagement with the under side of arm 25 to limit the upward movement of the stem and consequently of the hat-body y. In using this supporting device the hat is held in a vertical position on the plate 49, as shown in dotted lines in Fig. 7, a roller 58, held on an arm 59, adjustably mounted, as shown at 60, on standard 2 being provided to press the hat-body upon the plate 49 and prevent it from dropping therefrom during the trimming operation. The hat being so held its curled or upturned brim y will be in position to be engaged under the cutter 14 in a manner similar to that above described.

From the above description it will be seen that the improved edge-trimming machine constructed according to our invention is of an extremely simple and inexpensive nature and may, by variations in the patterns and work-supporting devices, be adapted to a great number of articles, such as shoes and metal or other patterns. It will also be obvious from the above description that the machine is capable of considerable modification without material departure from the principles and spirit of the invention, and for this reason we do not wish to be understood as limiting ourselves to the precise form and arrangement of the several parts herein set forth.
