Application filed December 1'7, 1913.
To aZZ whom it may concern Be it known that 1, JOHN H. Pn'rrrr, a citizen of the United States, residing at Great Falls, in the county of Cascade and State of Montana, have invented certain new and useful Improvements in York- Supporting Plates, of whichthe following 1s a specification, reference being had therein to the accompanying drawing.
This invention relates to a work'supporting plate attachment and has for its object the provision of a simple and efficient means for guarding the feeding mechanism of an ordinary sewing machine so as to prevent the feeding mechanism from shifting the goods, since the body portion of the device is positioned above and held in detachable position over the feeding IIIGOhZUIlSIH:
Another object of this invention is the production of a work-supporting plate attachment which is adapted to overhang the feeding mechanism of the machine and which is so formed as to be held at a spaced distance above the feeding mechanism, and thus preventing the plate from engaging the feeding mechanism.
vVith these and other objects in view this invention consists of certain novel combinations, constructions and arrangements of parts as will be hereinafter fully described and claimed.
In the accompanying drawing :Figure 1 is a perspective view of the worlesupporting plate, the pad being removed. Fig. 2 is a central longitudinal section taken through the plate, showing the pad carried thereby. Fig. 3 is a section taken on the line 3-3 of Fig. 1 looking in direction of the arrows. Fig. 4 is a plan view of the blank from which the plate is formed.
Referring to the accompanying drawing by numerals 1 designates the body portion of the work-supporting plate which is preferably rectangular in shape and which is provided with a central opening 2 for allowing the needle of a machine to pass therethrough. The body 1 is provided upon its side portions with the scored portions 3 adjacent which is formed the flanges 41. These flanges 4 are bent downwardly, as clearly the pad 5 upon the lower side of the body 1. This pad 5 may also be glued or cemented in the plate 1 and will be protected by means of the flanges 4. This pad is also provided Specification of Letters Patent.
Patented Dec. 29, 1914:-
Serial No. 807,320.
with an opening 6 which registers with the opening 2 formed in the body 1 for allowing the needle to have free passage therethrough. In order to support this body portion and pad at a spaced distance above the feeding mechanism of the machine and thereby allowing the mechanism to operate without injury to the same, one side portion of the body 1 is provided with an enlarged finger 7 which is integrally connected to the body 1 by means of the enlarged integral lip 8 which is bent under the scored lines 9. This lip 8 is longer than the width of the flanges 4 whereby the same will depend for a considerable distance below the lower edge of these flanges. The pad 5 also extends so as to rest snugly upon the under side of this lip 8 and engages the under side of the finger 7. This finger 7 carries a side flange 10 which is scored along the line 11 for allowing the ear 12 to be bent angularly to fit upon the lower side of the rear portion of the pad 5 as shown in Fig. 3, thereby securely holding this portion of the pad in engagement with the lower side of the finger 7. This finger 7 and a portion of the pad 5 are provided with registering openings 13 for allowing the usual set screw carried by the machine to pass therethrough for holding the device upon the machine.
When this device is in use, the finger extends across the usual work plates of the machine and is engaged by the screw which is generally carried adjacent the work plates. The finger will be held in position by this screw so as to allow the rear portion of the pad 5 to bear firmly upon the machine while the body portion 1 and the pad 5 will be held at a spaced distance from the body of the machine as clearly disclosed in Figs. 2 and 3. When the machine is in operation it will be seen that the feeding mechanism may be moved freely without engaging the cloth or without engaging the pad or plate as the lip 8 will hold the pad and body of the plate at a spaced distance above the feeding mechanism while the openings 2 and 6 will allow the needle to pass and operate freely.
From the foregoing description it will be seen that a simple and efiicicnt work-supporting plate has been produced which will guard the feeding mechanism of a machine and which is provided with means for holding the same so as to allow the several parts of the machine to operate freely and without interfering with the cloth which is positioned upon the plate.
It will be noted that the pad 5 by overhanging the feeding mechanism of the machine will prevent the possible injury to the feeding mechanism. Normally the body 1 and flanges 4: will hold the pad at a spaced distance above the feeding mechanism. If, however, a heavy blow is accidentally struck the plate at its central portion as where a pair of shears happen to fall upon the same, the plate will be depressed at its central portion although the flanges 4: will first strike upon the body of the machine, since the plate is formed of sheet metal. At this time the pad 5 will come into engagement with the feeding mechanism, and thereby prevent the teeth of the feeding mechanism from becoming blunt by striking the body 1 as would be the case if the pad 5 were not used.
What is claimed, is
A work supporting plate comprising a body, a lip extending from said body, a finger formed integral upon said lip, said finger positioned out of alinement with said body and extending in a plane parallel thereto, said lip being adapted to be secured to the body of a machine so as to allow the body of said work supporting plate to be positioned above the feeding mechanism of the machine, and a protector pad carried by the end portions of said body and finger whereby the feeding mechanism of the machine will be protected, said pad being adapted to come into engagement with the feeding mechanism when the body is accidentally knocked downwardly, thereby preventing the feeding mechanism from becoming injured.
In testimony whereof I hereunto afiix my signature in presence of two Witnesses.
