SEWING MACHINE ATTACHMENT.

Filed Juhe 26, 1940 INVENTORF' STEPHEN STA QUE T'T MEY Patented Aug. 26, 1941 Application June 26, 1940, Serial No. 342,450

3 Claims.

My invention relates to safety devicesfor sewing machines and has particular reference to devices or attachments for covering certain movable parts.

In certain sewing machines such as are used for manufacturing shirts and other wearing apparel, there are provided holes at the top of the head for lubricating certain moving parts. Oil must be frequently added into these holes with a result that, if there is a slight excess of the lubricant, tiny drops of it may be thrown out, falling on the work or on the operator's clothing. Oil

mayalso escape through a side slot in which moves a reciprocating hook or eye tensioning a thread fed to the needle. Moreover, the hook, being in front of the machine, causes accidents sometimes when an operator, watching his work closely, brings his face too near the machine.

Mv invention has for its object, therefore, to provide a simple device which can be readily attached to the head of .a sewing machine, the device being provided with a swinging cover for the oil holes, protecting them from dust and preventing escape of' the oil. The device supports a hinged cover for the reciprocating hook at the side, the latter being also provided with a receptacle for collecting all which may drop through the hook slot. I

My invention is more fully described in the accompanying specification and drawing in which:

Fig. 1 is a top view of the sewing machine head with my device in a closed position;

Fig. 2 is a fractional view of the device with one of the holes partly opened;

Fig. 3 is a side view of the device;

Fig. 4 is an end view of the same;

Fig. 5 is a view on a smaller scale showing the complete machine with my device; and

Fig, 6 is a plan view of the device with the on cover in an opened position.

My device consists of a plate I preferably made of metal and provided with a hole 2 opening into a slot 3 which can be fitted overa button 4 usually present on the head I of a sewing machine 6;

The slot 2 is somewhat narrower than the thickrims of the button, but the portions of the plate at the hole 2 can be resiliently spread apart, an

elongated slot 1 extending from the hole 2 to another hole 8, the plate around the second hole being in the shape of a narrow band 9. The-position ofthe plate I is further fixed by lugs It at the other side, extending downward along the side wall of the machine. The lugs have pivots I I supporting a channel-shaped or trough-like cover I2, normally extending downward over the side of the machine, enclosing a thread take-up hook I 3 and its slot II. The cover I 2 is partly closed at the bottom, forming a small recess or receptacle I5 for oil drops which may fall from the prising a flat plate,

hook. Suificient clearance is provided for a thread I6 passing from the hook to a needle II. An additional opening I8 is provided at the side for observing and adjusting the thread when necessary.

The cover may be raised on its pivots into a position shown in dotted lines in Fig. 4 for inspection of the hook and thread.

The plate I has holes I9, 20, 2|, 22 and 23,

registering with holes 24 and 25 (Fig. 2) and other corresponding holes in the head i. A lid 26, also made of a sheet material, preferably metal, is pivoted at 21 to the plate I and normally covers all the holes I9 to 23 as shown in Fig. 1.

-In certain types of such machines there are reciprocating'spindles extending upward throughthe hole 23. The lid 26 is provided with a small hole 28 for such a spindle. A small lid 29 is also provided, pivoted to the lid 26 at 30, for covering the small hole 28 when it is not needed. The lid 26 can be turned aside as shown in Fig. 6 when it is desired to add oil into the holes.

It is understood that my safety device for sewing machines may be further modified without departing from the spirit of the invention, as set forth in the appended claims,

I claim as my invention:

1. A safety device for a sewing machine having open 011 holes at the top of its head, comprising a flat plate placed on top of the head and having oil holes, the plate having a slotted hole at the sideand a narrow portion at the other side of the hdle forming a resilient clamp engaging the button-like projection on the head, lugs depending from the plate down the side of the head for stabilizing the plate, in its position and a lid for the oil holes pivotally supported on the plate.

2. A safety device for a sewing machine hava button-like projection on top of its head and an exposed thread take-up hook at the side, comprising a flat plate, means to support the plate on the projection, a channel-shaped cover hingedly connected to one edge of the plate and extending downward at the side of the head over the take up hook, the longitudinal edge of the cover partly abutting the side of the head, the lower edge of the cover being bent up, forming a well for collecting oil drops. Y

3. A safety device for a sewing machine having a button-like projection on top of its head and an exposed thread take-up hook at the side, commeans to resiliently support the plate on the projection, and a channel-shaped cover hingedly connected to one edge of the plate and extending downward at the side of the head over the take-up hook, theedges of the cover and the hook accessible.
