ATTACHMENT FOR SEWING-MACHINES.

Specification of Letters Patent.

Application filed March 12, 1908.

Patented Dec. 10, 1912.

Serial No. 420,677.

To all whom it may concem:

Be it known that I, HARRY B. WHITE, a citizen of the United States, residing at Canton, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Attachments for Sewing- Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to an attachment for sewing machines.

It pertains essentially to mechanism adapted to be applied to any wellknown type of sewing machine for the purpose of sewing a plurality of pieces of fabric in longitudinal series upon a strip of fabric or webbing, the pieces of fabric or patches being uniformly spaced apart.

One of the objects of my invention is to provide an attachment for a sewing machine whereby a series of fabric supports, such as those designated 11 in Patent No. 816,025 to Bert C. Maxwell, patented March 27, 1906, may be sewed to the fabric hangers 10, of said patented construction.

Other objects of my invention will be obvious from the description and disclosure of a machine embodying it, which for the purpose of illustration, I have selected.

Figure 1 is a perspective View of a sewing machine embodying my improvement. Fig. 2 is a plan view of a part of my attachment, detached. Fig. 3 is an end elevation of the machine shown in Fig. 1. Fig. 4 is a perspective view of a receiver and gage, detached. Fig. 5 is a perspective view of a portion of the fabric strip-carrying frame and a strip of fabric carried thereby. Fig. 6 is a plan View of a slide adapted to hold and guide the strip-carrying frame in two different positions of angularity. Fig. 7 is a perspective view of a receiver and gage, detached, and provided with a gage attachment.

In the drawing1 indicates as an entirety a suitable sewing machine upon which an attachment embodying my. invention is arranged. 2 indicates the bed or platform of the said sewing machine, 3 the arm, 4 the needle bar, and 5 the needle.

6 is the throat plate in the bed of the machine having a suitable needle aperture 7. The differentparts carried by the arm 3 for operating the needle'bar, and the bobbinoperating mechanism are not shown, as these parts may be of any well known construction, it being understood that my invention relates to a holding, guiding and step by step positioning mechanism for a piece of fabric to which a series of pieces of fabric uniformly spaced apart are to be attached.

8, 9, are guides, one secured at either side of the throat plate 6 and extending across the bed 2 to which they may be rigidly secured by means of screws 10, or in any other suitable manner. 11 is a slide fitted between and arranged to reciprocate between said guides 8 and 9. The attachment which I have illustrated in the drawings is adapted for the purpose of sewing a plurality of pieces of fabric equally spaced apart to a single strip of fabric, and each at an angle to the longitudinal edge of the strip of fabric. Hereinafter I will refer to the strip or web of fabric as a hanger 12, and to the pieces of fabric which are to be attached to the hanger as supports 13.

14 is a carrying and step by step posit-ioning frame for the hangers 12. This frame preferably consists of a bar or rod 16 to the opposite ends of which are secured laterally extending bars or plates 17, 18. Any suitable devices may be employed for securing the hangers 12 to the frame 14. For this purpose I have shown a series of prongs or points 19 carried by each of the end members 17, 18 of the frame. As it is desired to sew the fabric supports 13 each at an angle to the edges of a hanger 12, I have arranged to guide the frame 16 at an angle to the slide 11, which angle is the same one at which it is desired to attach the supports to a hanger.

20, 21, are guides arranged upon the slide 11 and spaced apart to receive and guide between them the longitudinal bar 16 of the hanger-carrying frame. 22 is a plate extending across the guideway between the guides 20, 21, and above the bar 16 and adapted to keep the latter in engagement with the upper surface of'the slide 11.

In order to provide a step-by-step movement for the hanger-carrying frame 14, and to facilitate the equal spacing apart of supports upon a hanger, I have recessed or notched the bar 16 at one side thereof as indicated by 23. The notches or recesses are spaced at the uniform distance apart which will uniformly space supports 13 as desired on a hanger 12. 24 is a pawl fitted to slide beneath the positioning a support upon a hanger prior plate 22 and to have its inner end enter and engage with the walls of any one of the recesses 28 in the bar 16 of the frame 14.

25 is a spring connected at one end to the slide 11 and having its other suitably con nected with the pawl 24: and arranged to normally hold the pawl in position in one of. the recesses in the bar 16. The pawl 24 has an upward extension 25 against which the thumb of an operator may press to release the pawl from the bar 16 in order to permit the step-by-step movement of the I 25 is a stop carried by the slide 11 and arranged to be engaged by and limit the outward movement of pawl 24:.

26 is a receiver and gage for receiving and to the sewing of it to the latter. All of the supports 18 which are to be attached to a given hanger are preferably cut of substantially the same width. The support receiver and gage 26 is arranged upon and suitably secured to the slide 11 at the angle to the guide for the bar 16 at which it is desired to attach the supports to a hanger. I have shown this receiver and gage as consisting of a bottom plate 26, a side wall 26 parallel to the guides 8 and 9, and an end wall 26 at the end of the guide and adjacent to the bar 16.

27 is an arm extending rearward from the bottom plate 26 of the receiver and gage and above the bar 16, and having its rear end suitably secured to the slide 11, as by means of screws 27 extending through the guide 20. The support receiver and gage 26 is held slightly elevated above the slide 11 so as to permit the ready introduction beneath it and free longitudinal movement of a hanger 12 carried by the frame 14:.

In order to bring the bottom of a hanger carried by the frame 14 into engagement with the throat plate 6, the slide 11 is longitudinally recessed above the throat plate and needle opening 7, as indicated at 28. The upper surface of the slide 11 is beveled or cut away at either side of the slot 28, as indicated at 28, 28 and the slot 28 is formed relatively wide to insure that a hanger 12 carried by the frame 14 may be brought flatly into engagement with the throat plate.

29 is a clamping bar arranged onthe opposite side of the slot 28 from the support receiver and gage 26. This clamping bar is arranged parallel to slot 28 and is pivotally connected at its rear end to a stud 30 carried by the slide 11.

31 is a spring secured at one end of the slide 11 and having its other end attached to the clamping bar 29 and arranged to normally hold the front end of the clamping bar elevated above the slide 11.

32 is a catch or latch pivotally connected the hanger.

at 33 to the slide 11 and having extending through it a recess 34 adapted to receive the front end of the clamping bar 29. When thrown upward into vertical position, this catch or latch will hold the clamping bar 29 depressed, and when pressed down into horizontal position the catch releases the clamping bar and permits its front end to rise under the action of the spring 31. The metal of the bottom plate 26 of the support receiver and gage 26, is preferably near its inner edge bent downwardly to conform as closely as possible to the beveled portion 28 of the slide 11 adjacent to the slot 28. V

In operation, a strip of webbing or hanger 12 is connected at one end to the frame 14 by causing the prongs 19 on the plate 18 to pierce the webbing. The webbing is then stretched toward the other end of said frame with its edges parallel tothe notched edge of the bar16, and the free end of the weba spring scale may be connected to the right hand end of the strip of webbing and in each instance that a strip is attached to the frame, the pull on the strip or hanger may be regulated until the same number of pounds pull is indicated on the spring scale, before the prongs 19 on the bar 18 are caused to pierce The opera tor then takes one of the supports 13 and places it in the support receiver and gage 26, arranging the left handand rear edges of the support in engagement with the walls 26 and 26 of the said receiver and gage. He then presses down the front end of the clamping bar 29 and throws up the latch 32. The clamp bar engages the said support 13 near the right hand edge thereof, and presses it and the hanger 12 down against the slide and clamps the same with the portion of the hanger pressed through the slot 28 held closely in engagement with the throat plate 6 as it is caused to travel across the latter. The needle is then set into action and the slide 11 with the hanger and support travel rearwardly beneath the needle, thus effecting the sewing of the support to the hanger at the desired angle. The latch or catch 32 is then thrown down so as to release the clamping bar 29.

The operator then presses rearwardly on the thumb piece 25 on the pawl 24 and releases the bar 16, which is then pressed to the right until it is stopped by the pawl dropping into the next recess in the said bar, which indicates and regulates the proper amount of movement of the hanger 12. Another support 13 is then introduced into the receiver and gage 26, and the above described steps in connection with the sewing of the support to the hanger are proceeded with.

This procedure is continued until the desired number of supports are sewed to the hanger, when the hanger is removed from the frame 14L by detaching it from the prongs on the bars 17 and 18 which pierced it, and withdrawing it from the machine.

The forward movement of the slide 11 may be limited in any suitable manner. For this purpose I have shown a downwardly projecting lug 36 on the guide 20 arranged to engage with an adjustable stop 37 attached to the bed plate of the sewing machine. The support receiver and gage 26 may be readily adapted for receiving and positioning supports of different widths and lengths. For illustration, in Fig. 7 I have shown a gage attachment 35 fitted to the side wall 26 of the support receiver and gage 26, so as to adapt the receiver and gage for positioning relatively narrow supports or patches 13. It will be understood that attachments such as 85 of various sizes may be used, as desired.

The slide 11 may be readily adapted for supporting and guiding the fabric carrying frame 14 at different angles to the line of movement of the slide and the bed of the machine. In Fig. 6 I have illustrated the slide 11 adapted to support and guide the said carrying frame 14 at two different angles to its said line of movement. In order to accomplish this result, a mere duplication of the parts for guiding and effecting the step by step movement of the carrying frame 14 are illustrated upon the slide.

My disclosures and description herein are intended to be purely illustrative and not in any sense limiting, as many alterations in the construction of the attachments and many apparently widely differing embodiments of my invention will suggest themselves to those skilled in the art of making sewing machines, and particularly sewing machine attachments, without departing from the spirit of my invention.
