FRANCIS J. FREESE, OF MONTREAL, CANADA.
SHOE-SEWING MACHINE.
SPECIFICATION forming part of Letters Patent No. 507,267, dated October 24, 1893.
'pplication filed August 9, 1892- Serial No. 6 N 1105913 To aZZ whom it may concern.-
Be it known that I, FRANCIS J OSEPH FREESE, of the city of Montreal, in the district of Montreal and Province of Quebec, Canada, have invented certain new and useful Improvements in Shoe-Sewing Machines; and I do hereby declare that the following is a full, clear, and exact description of the same.
This invention relates to chain stitch'wax thread sewing machines for sewing welted and turned work, my invention being an improvement on machines substantially such as represented in United States Patent No. 412,704, dated October 8, 1889.
Myinvention relates to means for securing a more even and uniform binding together of the parts to be united and to that end I introduce a clamping device to act upon the thread just before the take up has finished its binding pull upon such parts the effect being to prevent any more thread being drawn from the thread supply or even an extension of the length of thread between the thread supply and the work by reason of the elasticity inherent in all threads, the uniformity of bind being due to the fact that the degree of tension to which the thread is subjected between such clamping or looking point and the parts being united is always the same or uniform notwithstanding any variation in the thickness of such parts.
For full comprehension however of the invention reference must be had to the annexed drawings forming a part of this specification in which like symbols indicate corresponding parts and wherein- Figure 1 is a front elevation of a sufficient portion of a sole sewing machine of the class mentioned with my improvements added to enable my invention to be understood. Fig. 2 is a left hand side elevation of the portion of machine shown in Fig. 1. Fig. 2 is an enlarged detail View of the clamping device and its operating parts. Fig. 3 is a partial vertical section of the machine on line y y Fig. 1; Fig. 4 a detail sectional view of a portion of the head framework showing the burner for heating the thread rolls or sheaves. Fig. 5 is a right hand side elevation of the machine shown in Fig. 1.
The frame-work Aof the so-called head of the machine, cam shaft A, the awl-actuating lever A ,'the awl carrying lever A its awl a, the channel guide a, the feed cam A the lever A, actuated thereby and pivoted at A and slotted ata to receive a stud a extended outwardly from the horizontally sliding carriage B, having a depending portion 13, holding the channel guide (as will be hereinafter described) and the fulcrum for the lever carrying the awl to move them horizontally when the awl is in and so as to feed the shoe for the length of stitch to be made, the welt guide a the thread guideor loopeir B the carrying lever B to operate it, the hooked needle a its guide 8, the needle segment 0,", pivoted at a the link 13 to connect it with the lever B to move the needle segment, the said lever deriving its movement from a cam-groove as 200 at the inner side of the cam-disk A the shape of the said cam being shown by dotted lines in Fig. 5, the sliding gage B against which the upper on the last is pressed and rests while the stitch is being made, and the locking mechanism for the said sliding gage, are and may be all as common to the sole sewing machine shown in the patent referred to and so need not be herein further described.
The slide bar N to which the welt guide a is attached, a slot adjustable link containing a block, an adjusting bolt or device to hold the said block in place, the lever N pivoted at N and actuated by a suitable groove N at the left hand side of the cam-disk C, and the locking devices consisting of the pawl 113, pivoted to the lever 115 at 114, and the ratchet-block 112, the said lever 115, actuated by a cam-groove (see dotted line Fig. 3) at the inner side of the cam disk; the take up mechanism consisting of the elbow lever O mounted on the stud b and actuated by a groove in the cam disk or wheel 0', the shape of which is represented by full lines in Fig. 3, this lever, as shown having an ear bored to embrace the fixed stud b, so as to prevent the lateral movement of the lever G from the said stud, and the elbow lever G jointed by the link 0 with the arm 0 of the short sleeve 0 (see Fig. 1) mounted loosely on the stud 0 (see Fig. 3) held by the screw 2 (see Fig. 1), the opposite end of the said sleeve having the arm I) provided at its outer end with the roll b which arm I) constitutes the take up "ing device consists of an arm E (see Figs. 1,;
proper all these as well as the auxiliary take up mechanism consisting of the sheave 11 mounted loosely on the stud C nearitsinner end, the auxiliary take up lever proper I) having at its forward end the roll 3 cut away or notched at its rear end to leave a projection, as 4 and 5, the fixed stop 6, the upper projection 4t striking against the stop and limiting the upward movement of the auxiliary take up when lifted by the strain upon it of the thread i, passed over the roll b and the under projection 5 normally kept against the stop 6. by a suitable spring 7, the lever D, the cam D having the cam-groove D (see Fig.2) to actuate it, the said lever D pivoted at D and connected by the link D with the arm D of the short rock shaft D carrying the thread holder (1 on its inner end, are and; may be substantially as in United States Pat-l out No. 412,704, before referred to. In ad-{ dition to these parts and in combination there; withI arrange the clamping device to actg upon'the thread at a point between the ten-1; sion device and the take up and such clamp-g -2 and 2) which is bored as at E to allow of} the passage of air to the inlet J and pivoted by stud- E to the framework head, projectsi forward under the sleeve 0 carried by the stud or rock shaft 0 has an upward bend or Vertical portion E and a horizontal inwardly projecting free end E extending over said sleeve G and carries a steel clamping piece] 'E" upon its end directly over the sheave I), such clamping piece being preferably secured inplace bytwo dowel pins ff anda screwf',; and-having its bottom edge curved to corre-. 'spond with the periphery of such sheavew Ashort stud or pin F with beveled outer ondisset in the under side of the sleeve C im mediately over the main length of the arm -E and the arm has a vertical boring in line with 1 the axis of said sleeve to accommodate an adj ustment pin or screwGthelowerhalf of which isscrewed to work in a screw thread formed in a contracted part of said boring, and the upper half left smooth to receive the bearing end ofa set screw G working in the arm at right angles to the pin G. Just before the take up arm I) has finished its upward binding throw as shown in Fig. 2, the projecting; pin F in sleeve 0 makes contact with the adjusting pin G in the arm E and thereby depresses such arm (it being held up normally "by spring G and causes the clamping piece to hold the thread firmly between it and the; sheave b' nntil the take up lever has passed, the same point on its return or downward movement thus preventing any further thread 1 being drawn from the supply, or the exten-;
or less projection when larger or smaller thread is used, for while it is necessary to firmly lock the thread it is essential to avoid crushing or weakening it in any way by too great a degree of pressure.
To heat the thread sheaves or rolls 1) b and 3 I construct what might properly be termed a Bunsen burner in the framework head A so that the flame from it will impinge upon the sleeve C arm I) and auxiliary take up I), and through such parts heat such sheaves or rolls which are carried thereby. To construct sucn burner I bore a passage J in the framework head from a point in the front of sameimmediately behind and below the sleeve and other parts mentioned and meet the inner end of said passage with another boring or passage J extending from the side of the framework head and from this latter passage a small section of gas pipe J can projectto receive any desired connection from a gas supply. A section of tubing J having its inner end contracted to a very small opening J is inserted in the outer end of thepassage J and forms the burner proper, an air inlet J being bored from the side of the framework head into the tubing J just above the small opening J Prior to my invention herein described a wax thread sewing machine using a hooked needle to make achain stitch has never been provided with a looking or clamping device between the tension device and the take up.
Such novel features as I have herein shown but not claimed I reserve the right to make application for Letters Patent upon.
What I claim is as follows:
