Specification of Letters Patent.
Patented Oct. 21, 1919.
' To all whom it may concern:
Be it known that I. JOSEPH M. MnRRo w,
Hartford, in the county of Hartford, State of Connecticut, have invented certain new and useful Improvements in Sewing-Machines; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming apart of this pecification, and to the figures and letters of reference marked thereon. V
' This invention relates to sewing machines and more particularly to an advantageous arrangement of parts in the immediate vicinity of a sewing machine needle plate and the field 1 of cooperation therebelow of a needle and looper, which latter elements may be actuated in producing overedge stitching in-the well known manner exemplified in certain machines of the Merrow high speed type. Other elements introduced in the defined vicinity, include feeding and trimming devices, a needle guard and a guide for the looper thread.
' One of the objects of my invention is the provision in limited available space of a needle guard capable of being easily and quickly. adjusted. With this end in view the invention consists in a novel form of element, adequately supported and secured to its support by means readily accessible for manipulation to permit of any desired adjustment.
The invention is illustrated in the accompanying drawings in which,
Figure l, is a front view of one end of a sewing machine, partly in section to more clearly show features of my invention and elements associated therewith.
Fig. 2, is a transverse sectional view through certain of the parts shown in Fig. 1.
Fig. 3, is a plan view of the needle plate and parts supporting it.
Fig. 1, is a view in front elevation of the parts shown in Fig. 3, and
Figs. 5, 6 and 7 are detail views of an element comprising a guard for the needle and a guide for the looper thread.
Throughout the several views, like reference characters designate similar parts.
Referring to the drawings the numeral 3 designates the main frame of a sewing machine. The stitch forming implements illustrated comprise the curved eye-pointed needle 4 and looper 5. The needle is held in a carrier 6, which is pivoted at 7 and connected by a link 8 with the shaft 9. R0- tation of said shaft causes the needle, to be reciprocated in a curved path extending above and below the needle plate 10, and between looper 5 and a needle guard 11, hereinafter more fully described.
The looper 5, which is cooperative with the needle below the needle plate is secured to a carrier 12, and suitable means (not shown) are provided within the machine frame for actuating the carrier about its fulcrum 13 to move the looper in a curved path in proper timed relation to the move,
ments of the needle.
Secured to the end of the machine frame by screws as 14, and tongue 15, in groove 16 is a bracket 17, for supporting in the stitch forming vicinity various elements as will more fully appear. This bracket is recessed at '18 and 19, to provide space for the feed element 20, trimming element 21, and the movable trimming element carrier 22.
The feed element 20 is apertured as at 20 at the intersection of its plane of movement by element 5, 11, and 22.
7 On one side of the recess 18, the needle plate 10, is secured to bracket or support 17, as at 23, by the screw 24. At the opposite side of recess 18, the support 17, is formed to receive the element 25, which comprises an angle plate having legs 26 and 27, adapted to engage respectively the surfaces 28 and 29, of said support. The surface of the element 25, which engages surfaces 28, is grooved to receive the tongue 30, which keeps the element 25 also in position to engage surface 29.
These engaging surfaces are in parallelism with the direction of feed and with the plane of movement of the needle, as are also the engaging surfaces and the tongue and groove relation, indicated at 31, between element 25 and the needle plate 10. By virtue of this arrangement element 25, serves additional support for the needle plate, as well as an: alining influence therefor, and although the needle plate is rigidly secured by screw 24, the element 25, may be moved longitudinally to adjust the needle guard 11 carried thereby, with respect to the path traversed by the needle, as may be required to suit needles of different diameters.
When adjusted to locate the needle guard as desired, the element 25 may be rigidly held by a screw 32 threaded into a support and provided with a head to engage the elongated counterbored slot 33.
The needle guard 11, consists of a comparatively thin lateral wing projected from the depending leg 27 and extended to intersect the plane of the needle path, the needle engaging face of the guard being so disposed as tobe moved into substantially tangential relation to said needle path upon proper adjustment of the guard carrying element after the manner set forth.
Near the edge of element 25, from which guard 11 projects, there may be formed a longitudinally extending hole as 34, to serve as a guide for the thread of looper 5. This guide also facilitates initial threading of the looper, because in one position thereof (that best shown in Fig. 1.) the looper eye is in register with the guide hole.
Above the hole 34: the element 25, is cut away as at 35 to provide clearance for the wide part 36, of the feed element 20.
Having thus described my invention, what I claim is,
1. In a sewing machine in combination, a reciprocatory needle, :1 looper cooperative with the needle, an element comprising a guard for the needle and a thread guide for the looper, and means for supporting said element in proximity to the paths traversed by the needle and looper.
2. In a sewing" machine in combination, a cooperating needle and looper, a recessed support, a needle plate secured to the support on one side of the recess, an element comprising both a thread guide for the looper and a guard for the needle interposed between the needle plate and the support on the other side of the recess, and means for permitting adjustment of said element.
3. In a sewin machine in combination, a cooperating needle and looper, a support, an element comprising both a, guard for the needle and a thread guide for the looper,
and one of the elements whereby a definite relation is maintained between the engaging parts.
5. In a sewing machine in combination, a cooperating needle and looper, a recessed support, a needle plate secured to the sup port onone side of the recess, a needle guard element interposed between the needle plate and the support at the other side of the recess, and means for permitting adjustment of the needle guard element.
6. In a sewing machine, the combination of the following instrumentalities, to-wit: a reciprocatory needle, a reciprocatory looper cooperating with the needle, a feeding element apertured for the passage of the looper therethrough to opposite sides of the needle, a needle plate, a support for the plate, and a needle guard carried by the support below the plate and projecting through the feeding element on that side of the path of the needle opposite that trav-. ersed by the looper.
7 In a sewing machine, in combination, a needle, a looper, a laterally apertured feeding element through which the looper operates, a support on the side of the feeding element opposite the looper, a needle guard carried by the support and project ing toward the looper, and a looper thread guide located between the support and path of the needle.
