UNITED STATES PATENT oFF-ion. Y i
GUSS A. KILLER, 0F NUMA, IOWA.
SEWING-neem To all whom it may concern.'
Beit known that I, Guss A. MILLER, a citizen of the United States, residing at Numa, in the county of Appanoose and State of Iowa, have invented new and useful Improvements in Sewing-Machines, of which the following isa specification.
This 'invention relates to sewing machines of the lock-stitch type. e y
p The invention has for its object to produce a device of the class described which will be simple in construction, efficient in operation, land which may be-produced at a very moderate expense. A
A further obj ect of the invention is to simplify and improve the construction of the frame as well as that of the sewing mechanism supportedand uided .in said frame.
A further object of t e invention is to s implify and improve the construction and arrangement of the thread supporting and guiding means. l
A further. object of theinvention isto simplify and improve the construction and arrangement of the resser foot.
With these and-ot er ends in view which will readily appear as the nature of the invention is better understood, the same consists in the improved. construction, novel arrangement and combination of parts which Will be hereinafter fully described and par-- ticularly pointed out in the claims.
In the accompanying drawings has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited,
ut that changes, alterations and modifications within the scope of the'claims may be resorted to when desired.
In the drawings,-
Figure 1 is a side view of the improved sewing machine, the cover plate having been detached.
Fi 2 is a view 'similar to Fig. 1 but showing the needle bar in a lowered position.
Fig. 3 is a vertical sectional view on the line 3--3 in Fig. 1, but with the cover plate in osition.
ig. 4 is a sectional detail view taken on the line 4-4 in Fig. 1.
Fi 5 is a perspective detail view showing the s uttle bar and holder detached.
i u Specication of Letters Intent. i `i Patented Mar, 5, 1918, Application lled August 25, 1917. Serial No. 188,160.
Fig. 6 is a perspective detail view of the shuttle.
Corresponding parts in the several fige ures are denotel by like characters of reference. v
The frame structure of the improved device may be described as consisting of a flat hollow casing embodying a base portion 15, an upright portion 16 at one end of the base and a top portion or arm 17, the latter being preferably inclined in an upward direction with respect to the upright and the base. The'base, the uprightand the top arm 17 are provided along their side edges with forwardly extending flanges 18 adapted to support the cover plate 19 which may be assembled with the body of the casin machine screws 20 for the reception of W lich suitable apertures are provided, the said cover member coperating with the body portion of the base to form a hollow casing of proper dimensions to receive the operating arts of the device..
T e top arm 17 is provided with a vertically disposed sleeve 20 through which the needle bar 21 is guided for vertical reciprocatory movement, said needle bar being preferably of square cross section to prevent it from turning in the sleeve. Secured on the upper end of the needle bar is a hollow hand piece 22 which is adapted to contain a spool of thread 23, a slot 24 being formed through which the thread may be drawn from the spool. The lower end of the needle bar has a socket 25 for the reception of a needle 26 which may be an ordinary stout sewing machine needle, the same being secured in the socket by means of a set screw 27. A thread guide 28 is attached to the hand piece 22. Other thread guides 29 are mounted on the sleeve 20 of the casing and still another thread guide 30, the latter in the e nature of a coiled spring,is connected with v the lower end of the needle bar, said spring surrounding the needle so as to guide the thread closely adjacent thereto. Secured on the' flange 18 at the lower end of the top arm 17 is @bracket 31 on which is adjustably mounted a sleeve 32 carrying a presser foot 33, said slide being retained in adjusted position on the bracket 31 by a set screw 34, thus enabling Vthe presser foot to be readily adjusted according to the thickness of the material that -is to be operated upon.
,. .The base portion of the frame structure has a longitudinal groove 35 wherein the shuttle bar' l36 is guided for reciprocatory movement, .said shuttle bar being formed with a holder 37 for the shuttle 38 and said shuttle bar being also provided with a spring 39 to retain the shuttle in position. The shuttle is of ordinary construction and is adapted to contain a bobbin 40. The thread coming from the bobbin is guided through a slot 41 in the side of the shuttle and beneath a tension spring 42.
' -The shuttle bar isprovided adjacent to one end thereof with an anti-friction element such as a roller 43 which is engaged by a fork 44 formed on an arm 45 which extends `downwardly from a lever 46 which is fulcrumed within the casing on the arm 17,
' said lever being provided with a longitudinal slot 447 engaging the ulcrum member 48 so asto permit the said lever to have a limited sliding movement. One arm .of
the lever 46 engages a slot or recess 49 in' the needle bar so that by moving the latter up and down the lever will be rocked about its fulcrum and will lserve to produce a reciprocatory movement of the shuttle bar which will be properly timed to withdraw the shuttle from beneath the needle when of the needle in order that the looped portion of the thread may be carried within the casin to beengaged by the shuttle in the usua and well understood "mannen There has also been shown a clip plate 56 which is attached to-,the base' portion 15 within the casing by means of screws 57,
'said clip plate overlapping the shuttle carrylng bar for the purpose of retaining the 'v latter in the roove 35 wherein it is arranged for reciprocation'.
From the .foregoing description taken connection with the .drawings hereto an` nexed the operationand advantages of this invention will be. readily understood by those skilled in the art to which it appertains. The device may beusedfor sewing f and mending shoes, harness and other i leather goods as well as for sewin sacks and the like and it is in fact useful ora greatl variet of urposes whiehwill readily sug-l gest t emse ves. The material that is to be o erated upon is supported on the base portion of the frame beneath the presserfoot,
the latter bein roperly adjusted to suit the .thickness o t e material that is to be operated upon. YByiorcing the needle downwardly through the goods and subsequently retracting the same, a lock stitch will be formed b the con'oint operation of the needle an the shutt e. of one stitch, the device is adjusted with respect to the goods (or vice versa) to the proper position for forming the nextstitch,
after which the operation is repeated as will be readily understood. The construction and operation f the im roved device is extremel simple and the evice is thoroughly use l for the purposes for which it is intended.
