COVER FOR SEWING-MACHINE PULLEYS.
Application filed May 19,
This invention relates to an improved cover for the pulleys of power sewing machines, particularly pulleys above the table at the fly-wheel and the bobbin winder, which pulleys are kept well lubricated and sometimes damage when goods is being sewed. The present invention relates to a cover which is readily installed and easily removed. It is also adapted to permit the operation of the clutch which projects, in most machines, beyond the fly-wheel on the head of the machine and is necessarily available for stopping and starting the machine.
The invention is illustrated in the accompanying drawing in which Figure 1 is a side view of the cover with part of a sewing machine shown in dotted outline. Figure '2 is a front View of the device shown in Figure 1. Figure 3 is a face View of a blank before it is trimmed and Figure 4 is a side view looking at the reverse side of Figure 1 and raised from its fastening means. Figure 5 is a perspective view of the parts shown in Figure 4 and Figure 6 is a section on line 66 in Figure 1. 1 I
The main part of the cover is a plate 10 which is provided with a flange 11 which flange is wideenough to extend across the belt and pulley as used on an ordinary powerdriven sewing machine. The machine is shown in dot-ted outline and the head 12 supports a main shaft on which is usually mounted a fly-wheel 13 and a clutch 14 which is turned to either throw the machine in or out of operative connection with the pulley 15 driven by the belt 16 which extends down through the table 17 to the driving pulley.
In front of the belt 16 and adapted to be put in and out of contact with it is the pulley 18 of any of the usual forms of bobbin winders 19. 7e provide a curved horn-like extension 20 on the plate 10 which extension has a flange 21 in extension of the flange 11. The horn-like extension is made in a separate piece from the main part 10 and is welded thereto.
This is the usual construction because when the part 10 is cut to meet the conditions presented by the machine on which it is to be mounted, the cutting is easier and the extension is subsequently fastened on. The cutting and its reasons are described hereinafter.
The upper part of the plate 10 is provided when it is desired to have an adjustable fastening means.
The plate 23 is usually tapered at its ends so that it fits snugly into the tapered socket 27 which is welded or otherwise suitably secured to the plate 10. The frictional contact of the fastening plate 23 and the socket 27 is further assured, when desired, by forming tapered ribs 28 on the plate 23.
In order to adapt the cover for different makes of machines it is necessary to allow for various heights of the main shaft and its pulley from the table and also the angle at which the belt 16 runs relative to the table.
To make the various adaptations possible, we
make the plate 10 at the extreme height as shown in Figure 3, extendingthe flange 11 to the bottom on one side and having its end opposite about the centre of the opening 22 on the other side. Then We cut off the plate 10 to form the desired height and angle for the particular machine.
The lines at a, b, 0, cl, etc., indicate how the plate can be made to conform to various angles and heights of machines assuming that the out part is to be mounted on the top of the table 17. The cuts which have been indicated at various angles are, of course, only suggestive, inasmuch as the angle of the belt and the height of the shaft of the machine from the table are the factors that locate the shape of the guard. The plates 10 are made in excess of the normal machine and then cut as desired. The socket 27 is then placed at the bottom of the plate 10 and the plate 23 secured in position. After the initial attachment, whenever the cover is to be installed or removed, it can be done without the tools as will be evident.
Various modifications can be made in both the form and dimensions of the device without departing from the scope of the invention.
We claim:
A cover for sewing machines comprising a use of plate and a horn-like extension, both having by the cover is readily mounted or'relnovecl marginal flanges a socket on the bottom of the plate, a vertically arranged plate to enter the socket to maintain the plate in position, 5 the plate having an elongated opening to permit the passage of the clutch of a sewing machine ancl to allow Vertical movement Wherefrom the plate.
In testimony whereof We affix our signatures.
FRANK DREYER. EDWARD J. LAMY.
