FREDERICK ENGLISH, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO WILLIAM PAYNE,
OF PHILADELPHIA, PENNSYLVANIA.
SE WIN G-MACHINE Specification of Letters Patent.
Patented Nov. 24, 1908.
Application filed. June 13, 1907. Serial No. 378,774.
To all whom it may concern:
Be it known that I, FREDERICK Enomsi-i, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a certain new and useful Sewing-Machine, of which the following is a specification.
The principal object of the present invention is to provide a sewing machine capable of running at the requisite high speed and adapted to make a seam and an overseam with a lock stitch at the same time and capable of being operated, if desired, for performing either one or the other of these operations separately.
Another object of the invention is to provide an over-edge machine which is capable of working over the edge of a comparatively thick fabric or number of fabrics.
Other objects of the invention, as well as its nature, characteristic features and scope will be more fully understood from the following description taken in connection with the accompanying drawings forming part hereof, and in which Figure l, is a front view of a sewing machine embodying features of the invention.
Fig. 2, is an end view of the machine taken from left to right in Fig. 1. Fig. 3, is a plan view of the table of the machine with certain of the parts removed. Fig. 4, is a plan. view showing parts beneath the table of the machine. Fig. 5, is a plan view, Fig. 6, a front view and Fig. 7, an end view of trimmer mechanism, and Fig. 8, illustrates mechanism for raising and lowering a looper.
In the drawings 1 and 2, are a pair of needles arranged one in advance of the other and out of line with each other relatively to the line of feed. These needles are reciprocated by means which are not devices of the invention and which comprise a needle bar 3, reciprocated in respect to a head 1, by means of an oscillating lever 55, connected with the needle bar by a link 6, and oscillated by a link 7 from an eccentric 8, on the main shaft 9.
10, are the feed dogs and there is nothing unusual about them. They are operated by a link 11, which in turn is operated from an eccentric 12, on the main shaft 9, and from a swinging frame 13, carried by the base of the machine.
it, is a left-hand threaded looper for the front needle which is the one that makes the plain seam.
15, is a pick-oil spreader for the second needle. These parts 1 1 and 15, travel back and forth in a straight path ranging crosswise of the direction of feed, that is, aarallel with the main shaft 9, and they also oscillate back and forth in the direction of the feed. These parts 14: and 15, are connected with a carrier 16, to which motion in four directions is imparted. This carrier 16, is reciprocated parallelwith the main shaft, sliding upon guides or rods 17 and 18. The rod 17, being fixed in the frame of the machine and a link 18 is connected with the carrier 16 and with one arm 18 of a bell-crank pivoted at 19, the other arm of which is connected with an eccentric strap 20, driven by an eccentric 21 on the shaft 9. As the shaft 9, is rotated the described mechanism shifts the carrier 16 from right to left, in Fig. 1. The rod 18, is attached to a bracket 22, Fig. 1, which is pivoted on the rod 17 and it is connected by a link 23, Figs. 1 and 2, with an eccentric on the main shaft 9. When the main shaft is turned the rod 23, and its eccentric operate to swing the bracket 22, backward and forward, thus oscillating the carrier 16 with its parts 1% and 24;, is a right-hand looper arranged to work over an edge of the table cross-wise of the direction of feed and it works in an elliptical path and may be made to rise as high above the table as is required for overedging thick work, much thicker than can be over-edged with machines of ordinary construction. The looper 24L, is carried by a holder 25, pivoted as at 26, to a rising and falling member 27, Fig. 8. This rising and falling member 27, slides on a fixed rod 28, and is provided with a fork that engages an eccentric 29, on the main shaft. The rod 28, is of rectangular cross section; this being one means of preventing the member 27 of turning upon it. The holder for the looper is also pivotally connected with a link 30, that is pivoted to the depending portion 31, of the lever 5. In consequence of the described connections the pivot 26 rises as the part 25 is turned about it as a center, so that the looper 24, or more properly, the working end of it, describes an elliptical path. The rear needle cooperating with the part 15 and looper 2 1, when the parts named have the motion described, produces an overseam stitch which is elastic and therefore desirable.
It is to be understood that there are four threads employed, one for each needle and one for the part 14: and one for the part 24, although it is possible by simply dispensing with some of these threads to make either the straight or the over-edge seam. F or the class of work for which the machine is intended, it is desirable and in fact practically necessary to provide a trimmer and a description will now be given of the trimmer shown inthe drawings.
32, is a casting which forms the bearings for the movable arm of the trimmer and it is secured to the table of the machine. The casting 32, extends upwards and toward the end of the machine, as shown in Fig. 6. To the end of the casting 32, is secured a plate 33, to which is attached the fixed knife 34-.
35, is a guard consisting of a sheet of metal connected with the casting 32 and the plate 33, and serving to deflect the trimmings.
36, is a holder for the movable knife 37 and its pivot pin is journaled in the casting 32, in Fig. 3. The pivot pin Fig. 5 is shouldered near its right hand end for the reception of a spring 38, which bears upon a cap 39, secured to the casting 32 and thus tends to shift the holder 36 toward the left and keep the movable knife 37 up to its work in cooperation with the fixed knife 3%.
40, is a link connected with the free end of the holder 36 and with an eccentric strap arranged upon the main shaft 9, so that the revolution of the shaft swings the knife holder 36 about its center and thus causes the knives to cut or trim. In the stitch regulator there is a crank pin 43, that may be moved more or less out of center with a disk 44:, carried on the end of the shaft 9. To this crank pin 43, is connected a link 42, which in turn is connected with a coupling &5 that serves to operate the swinging frame 13 and in turn operates the link 11 that operates the feed.
Having thus described the nature and objects of my invention what I claim as new and desire to secure by Letters Patent is 1. A sewing machine for simultaneously making a lock-stitch seam and an over-edge seam which comprises a pair of needles one in advance of the other and out of line with each other relatively to the line of feed, an overseam thread carrying looper arranged to work over the edge of the work plate in an elliptical path, an interconnected looper and pick-off spreader arranged to travel in two slightly curved paths and to oscillate at each end of the stroke back and forth of the needle and whereof the pick-off spreader cooperates with the overseam looper, and mech anism for working said parts, substantially as described.
