FINGER-GUARD FOR SEWING-MACHINES.

Specification of Letters Patent.

Patented Dec. 5, 1916.

Application filed May 11, 1916. Serial No. 96,858.

To all whom it may concern:

Be it known that I, MAYBELLE J. HARSANT, a citizen of the United States, residing at Selby, in the county of Contra Costa, State of California, have invented certain new and useful Improvements in Finger-Guards for Sewing-Machines; and I do hereby declare the following to. be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to finger guards or protectors, and is adapted particularly for use upon sewing machines.

The primary object of the invention is to provide a guard applicable to a sewing machine to prevent the fingers of the operator from becoming mashed or injured by the needle of the machine, which is simple and inexpensive of construction, which is applicable to machines of varioustypes and constructions, which will not in any way interfere with the operation of the machine, and which is capable of being readily moved out of the way when desired.

A further object of the invention is to provide a guard of this character which is of such formation as to permit of the machine operator seeing every operation of the machine needle and the cooperating parts thereof while the guard is in operative position.

W ith these objects in view, together with others which will appear as the description proceeds, the invention resides in the novel combination and arrangement of parts, all as will be described more fully hereinafter, illustrated in the drawings and particularly pointed out in the claims.

The invention will be best understood by reference to the accompanying drawings, wherein Figure 1, is a fragmentary view of a conventional form of sewing machine and illustrating a guard embodying my invention applied thereto, the view being taken from the operators position, Fig. 2, is a side elevation taken at right angles to that of Fig. 1, Fig. 3, is a view similar to Fig. 2 and illustrating the guard moved to inoperative position, and Fig. 4, is a longitudinal sectional view taken through the device as illustrated in Fig. 2.

Referring now more particularly to the drawings, 5 indicates a portion'of the machine frame or head, the same being equipped "with the usual reciprocating needle bar 6, and the end of which is provided with a needle.

The invention resides in the provision of a plate between the reciprocating needle bar of the machine and the operator, so that the fingers of the operator in guiding the cloth to the needle will be prevented from coming n contact therewith or being mashed or inured by the presser foot. This plate is secured to the machine head in such manner as, when not in operative position, to not interfere with the feeding of the cloth to the needle, and is capable of being swung or moved to inoperative position, or out of the way, to'enable the machine operator to have access to the needle, presser foot, or other correlated parts to repair the latter or to apply the various machine attachments to or adjacent the needle.

In the preferred embodiment of the invention, a. rectangular frame 8 is provided.

This frame may be made of light durable.

metal, such as nickel, aluminum or the like, and its longitudinal inner edges are grooved as at 9 for the reception of a dia'phanous pane such-as glass 10. The glass 10 is of a size to conveniently fit within the frame, in order that the operator of the machine may view from his position the various operations of the needle and its associate machinery. The upper lateral edge of the frame 8 is also grooved upon its inner face to'accommodate the edge of the pane 10. The grooves 9 in the side bars of the frame are open at their lowermost ends, and a swinging channeled gate 11 is pivoted as at 12 to the lowermost end of one of said bars to permit of the glass pane being inserted within the frame and to be swung to closed position after the pane has been properly adjusted to prevent the latter from becoming detached from the frame. Ears 13 project in spaced parallel relation beyond the uppermost end of the frame 8 and preferably at the lateral edges thereof, thesaid ears being provided with longitudinally disposed slots 14.

To secure the above described frame upon the machine, a block 15 is provided. This block may also be formed of suitable metal, and provides a pair of spaced arms 16, the latter adj acent'their ends being apertured to permit of the application of retaining screws or bolts 17 to the head. These screws project laterally through the arms and are adapted at their innermost *ends for engagement with the head portion of the machine most ends ofthe said screws being equipped with padding elements such as rubber 18 to prevent scratching or abrasions of the machine head. It will be observed that the inner face of one of the arms 16 is inclined as at 19, the construction permittin of the block being attached to machine heads of various shapes and sizes. block 15 are provided with outwardly ex- .tending pins or trunnions 20, the latter being adapted for engagement within the elongated slots 14 in. the ears 13 carried by the frame. Stops 21 project outwardly from the block ends at the rear thereof to limit the forward swinging movement of the frame when the latter is depending from the retaining block. A transversely disposed shoulder 22 is also arranged upon each of the ends of the block 15, this shoulder 1imit-. ing the movement of the frame 8 When the latter is swung to inoperative position, the said shoulders being so arranged as to abut the ear edges when the latter assume a position at right angles to the block.

In operation, the block 15 is, through the screw member 17, adjusted to a sewing machine head slightly in advance'of the needle bar 6; The frame swings upon the pintles 20 into downward position, or parallel with the needle bar 6, slightly in advance of the latter, and being spaced at its lowermostend slightly above the machine table. As cloth is'fed to the needle, the guard will prevent the fingers of the machine operator from passing with the cloth beneath the reciprocating needle. Stops 21 limit the rearward swinging movement of the frame 8. It will be'o-bserved also that the diaphanous pane 10 will permit of the operator viewing the opthe head 15, whereupon a slight forward The ends of the sight viewmovement delivered to the frame will cause the same to move a distance equal to the length of the slot 14, whereupon the cars 13 will be locked between the shoulders 22 and the upper extremities of the stops 21. From this construction it is apparent that an extremely simple and eflicient means is provided for attaining the objects set forth, and one which is tho-roughly durable and reliable. I

\Vhile I have herein shown and described a particular or preferred embodiment of the invention, I desire to have it understood that I need not confine myself to all the precise details of construction herein set forth by way of illustration, as modifications or variations may be made without departing from the spirit of the invention or exceeding the scope of the claims;

What is claimed is:

1. In combination with a machine of the class described, of a block, arms projecting upwardly from said block, screw members securin said arms to-a machine head, pintles projecting from the ends of said block, shoulders above said pintles, stops on said ends to the rear of said pintles, a frame, means projecting from one end of said frame and being provided with longitudinally disposed apertures for engagement with said pintles, and a diaphanous member in said .frame, substantially as described.

2. In a device of the class described, a block, arms projecting from said block, inwardly extending screw members on said arms, the end of said block being equipped with shoulders and stops, a frame, ears projecting from said frame and pivotally connected .to said block ends, the said frame being provided upon its inner edges with longitudinally disposed grooves, a pane in said grooves, and a gate closing the lower end of said frame,'substantially as described.

In testimony whereof, I affix my signature, in the presence of two witnesses.
