Appiicatibn filed. u'ay i'a, 1925. serial u 29,871,

"This invention relates to apparatus for cutting hat sweat leathers and otherstrips to various predetermined to move on the base 10 in curved paths extending concentricallyabout the axis of of material lengths.

less in excess ofthat required 'for the larger sized hats-,and 1t is necessary for; the manufacturer to out these sweat leathers or strips.

to the" proper length for hats o f various sizes. The object ,otthe present invention is to provide a simple, durable and easily operated machine or cutting device whereby of various sizes. v I

A ifull'understandlng ofthe invention can best be' given by a detailed description t a sweat -leather cutting machine embodying the features of the invention, and such'a description will now be given in connection with the accompanying drawings illustrating such an approved embodiment.

'Insaid drawings 1 it p Fig. 'l'is a plan view of the machine, Fig. 2 is an endviewf V Fig. 3'is asection taken on 1ine33 of Fig. 1 but on a larger scale; 7

Fig. L'is a section taken on line of Fig. 1; and I f Fig. is a section taken on'line '5'5 of Fig.1.

'Referring to thefdrawings, the operative parts of the machine illustrated are mounted on a base piece 10 which is supported by a pedestal 11., For supporting the strips to be out there ,is provided a stri support tormedby a central portion or b ock 12 secured toithe base piecef10 and two end portions or blocks 13 and '14 which are slid ably mountedon the base 10so as to be movable toward and away from the central block 12. Thefbase 10 and blocksl2, 1'3 and 14 are desirably made of wood, and the base.

10 has a metal plate 15 on" its upper side to blocks v13"a nd 14 slide, and the blocks. 12,13

and l thave metal plates .16 secured fonftheir upper sides providing the supporting surface on which .the sweat leathers or other strips are placed The blocks 12, "13 and 14;- are provided with u s anding edge portions providing a' v positioningshoulder; against which the sweat leathers may be positioned on the supporting surface, and this positioning shpulder formed by the inner edges of Sweat-leathers tor'hat's assup'plied to the I n'ianu'facturer are usually o'fi-a length more or suchupstandin jportions is curved to correspond to the shght curr' ature of the sweat leathers. The blocks 13 and 14 are guided curvature of the positioning shoulder. F or this purpose curved slots .21 are formed in the bearing plate 15 and the blocks 13 and 14 are held to the bearing plate and guided in their movement by screws 22 extending through theslots 21, the body of the base piece 10 being cut away as shown at 23 in Fig. 5 to permit "of insertion of the screws and toaccornmodate the screw heads.

A strip cutting device is provided on the outer end of each of the blocks 13 and 14 as shown. Each such tout-ting device as. shownconsists of a pair of shears 25, the lower blade ofiwhich is fastened to the end 'o fthe block with its cutting'edge flush with the supporting surface. Instead ofhaving the shears arrangedto cut all the way across the leather strip, it is sometimes desirable to have them arranged as shown so that they do notout entirely across the strip but leave a smalluneut width offleather at the bottom, or longer, edge of the strip so that'extending tabs may be shaped at theends of the strips for overlapping when the strip is sewed into the hat.

Located within an opening in thecentral block'1j2, is a gear wheel mounted on a shaft 31 provided with a hand wheel 32. A toothed bar 33 connected to the block 13 by a link 34 extends over the gear wheel 30 with its teeth in engagement with the teeth of the wheel, and a similar toothed bar 35 connected to the block 14 by a link 36 ext-ends beneath the gear wheelwith its teeth meshingwith'the wheel teeth. When the handle 32 is turned in one direction, thegea'r wheel will 'act through the toothed rods 33 and '35 to move the blocks 13 and 14 outward-,there-' by. lengthening the support, and when the handleis turnedin the other direction. the

provide .a bearing surface on which the. gear wheel will act to draw the blocks incomlnodate the toothed rods and links.

E01- indiicating the adjustment of the jsu p port, that is, the length to which a strip positioned on the supportwill cut, a scale 40 graduated to indicate by hat sizes various positions of adjustmentof the support is provided on the upstanding portion 20 of one of thefmovable 'blocksg and a. pointer shown in Fig. 1 and by dotted lines in F ig.,

2. This cover plate is of suitable weight to hold the strips in position on the support, and its free edge is desirably curved to fit close to the curved positioning shoulder of the support. f

In the use of the device, the hand wheel is turned one way or the other as may be required to bring the pointer ll into position to indicate on the scale the size of hat for which the sweat leathcr is to be cut; the leather is laid fiat on the supporting surface of the support with the concave edge of the leather against the positioning shoulder of the support, and the cover plate is lowered to hold the leather firmly positioned. ,By means of the shears 25 the leather is then cut to the required size, the cover plate is lifted, and the cut leather is removed.

s It is usual to have the hat makers-name or some suitable design printed or embossed 7 on thesweat leathers before they are cut to various sizes, and it is desirable that such names or designs on theleathers shall be located centrally of the cut leathers or otherwise uniformly located on the cut leathers as to have a uniform location in theliats.

In addition to other advantages of having the machine made with two oppositely movable. end portions of the strip support, instead of having only a single movable portion at one end, this construction has the advantage that hat leathers to be cut of different lengths may all be placed on the support with the markings onthe leathers in the same position with relation to the lengtl'r of the support.

It is to be understood that the invention is not to be limited to the exact construction shown, but that it includes changes and modifications thereof within the claims.
