SEWING MACHINE FABRIC TRIMMING ATTACHMENT Filed Jan. 2, 1962 2 Sheets-Sheet 2 WI I Illlllllllllllfillllllllll off INVENTOR. Gilbert Fowl er,S|:
ATTORNEY United States Patent 3,14%,590 SEWENG MAQHIINE FAERIC TRIIMMHNG ATTACNT Gilbert Fowler, Sin, 1128 Broadway, Brooklyn, NJY. Filed Jan. 2, 1 62, Ser. No. 163, E49 6 Claims. ((Jl. 1l2--l27) This invention relates to a novel sewing machine mechanism and more particularly to a cloth trimming attachment for trimming the edge portions of superposed fabric sections parallel to the direction of travel, the saidfabric sections being stitched simultaneously with the trimming operation.
Whereas it is frequently desirable to arrange fabric sections in flat overlapped relation to each other, the appearance or finish of the edge portions of the respective fabric sections and the economics involved with respect to achieving the sought after appearance have been formidable problems to both designers andmanufacturers alike. The sewing machine attachment to be hereinbelow disclosed now enables, both with rapidity and facility, the simultaneous trimming of'the respective edge portions of superposed fabric sections and the stitching together thereof simultaneously therewith, a step or layer off-set effect being established for aesthetic purposes useful, for example, when the stitched and finished edge portions are to form the trim for a cloth coat collar, etc.
Essentially the present invention is directed to providing a sewing machine attachment of the above nature wherein the fabric sections may be fed. to the trimming mechanism with the edges thereof substantially in alignment although rough and untrimmed, the said fabric sections, upon leaving the attachment, being trimmed, stitched, and the edge of. the upper layer being inwardly oif-set with respect to the trimmed edge of the lower layer, thus providing a stepped effect greatly improving the appearance ofthe trimmed superposed. and united fabric sections.
Consonant with the foregoing, the instant invention has for an object the provisionof a sewing machine fabric trimming attachment which maybe readily. adapted to a conventional sewing machine.
Another object of the present invention is to provide a sewing machine .attachrnentof the above character wherein the shearing members are reciprocally actuated through a single motivating linkage, said motivating linkage being in synchronism with the cloth feeding mechanism.
A further object of the present invention is theprovision of a cloth trimming mechanism having two pairs of shearing members, the pivotal-i blade of each pair of shearing members being automatically-and continuously tensioned with respect to the respective stationary blade thereof.
A still further object of the instant invention is the provision of a new and useful-sewing machine fabric trimming attachment wherein the trimming devices are so disposed as to cut the respective edges in parallellines adjacent the stitchingmechanism of a conventional sewing machine.
Still another object of thepresent invention is to provide a sewing machine fabric trimming attachment having upper and lower pivotal blades and-upper and-lower stationary blades, the upper stationary blade'being further employed as a platform for supporting an upper fabric section andfor separating said section from a lower fabric section.
It is a still further object of this invention to provide a sewing machine fabric trimming attachment accomplishin the objectives noted above, which attachment is of extremely simple construction, economical of manufacture, and highly reliable in operation.
Further and additional objects and advantages will become apparent to those skilled in the art as the description proceeds with reference to the accompanying drawings, wherein:
FIG. 1 is a perspective view of a machine showing superposed layers of fabric being fed into the shearing members of the sewing machine attachment according to the present invention;
FIG. 2 is a top plan view of the attachment in isolation, the cover member being removed therefrom;
FIG. 3 is a front end elevational View taken along line 3-3 of FIG. 2;
FIG. 4 is a front end elevational view taken along line 44 of FIG. 2;
FIG. 5 is a side elevational View of the device shown in FIG. 2; and
FIG. 6 is a rear end elevational view of the device shown in FIG. 2.
Referring in detail to the accompanying drawings, the invention is shown operationally attached to a conventional sewing machine in FIGURE 1 wherein the attachment is generally designated by numeral 1 and is partially concealed by cover member 2. superposed fabric sections 4 and 6, the lower and upper sections respectively, are fed along the work supporting base plate 8 by virtue of the eccentric movement of feed dog It) shown in FIG- URE 2 of the drawings and the action of presser foot 12 which is adjustably mounted and held rigidly by fixed support member 14. The said presser foot is provided with an opening 16 for the needle 1d, the said needle being carried by a needle barZt which is reciprocated in the usual manner in the overhanging arm of the machine.
The purpose of the instant device will be appreciated upon observation of the completed condition of the outgoing product as seen in FIGURE 1 at 22. To that end an off-set relation between the upper and lower fabric section is accomplished with respect to the edge portions thereof. In addition, the fabrics are stitched to one another, and their respective edges are trimmed.
With'reference to FEGURES 26 or" the drawings a full understanding of the structural embodiment of the present device will be realized. Accordingly, the embodiment of the invention illustrated thereby is comprised of a substantially U-shaped bearing block 24 which is supported by the said base plate 8 and firmly secured thereto by machine screws 26 and 2%. First stationary blade 39. and'pivotal blade 32 cooperatively associated therewith and second stationary blade 34 and pivotal blade at cooperatively associated therewith comprise the pairs of shearing members adapted to trim the upper and lower fabric sections, respectively. A first horizontal shaft 38rotatably journalled at all, 42 within the arms of the said bearing block 24 and slidably supported thereby, and second horizontal shaft 44, comprise the pivotal blade extensions disposed at substantially right angles therewith and arranged to transmit the below described reciprocating pivotal motion to the said blades. Connecting member 4-6 is provided with a slotted end 48 permitting reception thereof over the said first horizontal shaft for seating of the said shaft within passage 49. Machine screws Eli and 52 are provided to firmly secure the said connecting member to the said first horizontal shaft subsequent to the positioning thereof as aforedescribed. Bore 54 provided in the other end of the said connecting member is adapted to receive-the said second horizontal shaft rotatably and slidably. Elbow-crank lever 55 pivotally secured at one end to connecting member 46 by means of machine screw 58- depends downwardly from said connecting member through opening 60in the said base plate and beyond elbow pivot 62 is connected at looped end 64 to oscillating shaft 66 and secured thereto by machine screw 68. Thus, the vertical reciprocating motion imparted to elbow crank lever 56 is transmitted di- 3 rectly to connecting member to wherefrom the said n10- tion is transposed into angular reciprocating motion with respect to the said first and second horizontal shafts, the said pivotal blades integral with said shafts being ultimately reciprocated in shearing relation with their respective stationary blades.
Horizontal shaft 33 enveloped by compression spring '70 at a portion of the shaft extending without the bearing block 24, provides continuing resilient contact between pivotal blade 32 and stationary blade 349. in addition, horizontal shaft 38 may be manually adjusted longitudinally against bearing block 24 by nut '72 on the threaded end of shaft 38 to place pivotal blade 32 in proper cutting relationship with stationary blade 30 or out of cutting relationship therewith if that be desired.
In operation, superposed layers of fabric 4, 6, to be trimmed and stitched in off-set relation, are fed through the device, the edge portion of the upper layer 6 being supported upon and automatically moved across the platform provided by first stationary blade 30, the edge of the lower layer being supported upon and automatically moved across second stationary blade 34, which as aforementioned is disposed fiush with the plane of base plate 8. Thus, separation of the edges of said upper and lower fabric sections occurs during the period of movement of said fabric sections across the respective stationary blade platforms, trimming and stitching being also accomplished at that time. The width of the step resulting by dint of the off-set trimming operation may be varied by adjusting the position of first stationary blade 3%? which may be predetermined and secured by machine screw 31 which connects the said platform thereof to the said base plate 55. By reason of the aforedescribed self-adjusting feature possessed by first pivotal blade 32 with respect to first stationary blade 5t shearing relation therebetween will be maintained notwithstanding re-positioning of the said first stationary blade.
Both the structural and operational characteristics of the invention having been described, it will be understood that changes may be made in the form, construction, and arrangement of parts from that disclosed herein without in any way departing from the spirit of the invention or sacrificing any of the attendant advantages thereof, provided, however, that such changes fall within the scope of the claims appended hereto.
