' NEEDLE AND OIL GUARD FOR fiTWINGQvIAGHENES.

Specification a Letters Patent.

Patented Oct. 18, 1921.

Application filed February 4, 1926. Serial No. 356,134.

To all whom it may concern:

Be it known that I, ammi J. Bnn'rrrn, a citizen of the United States, residing at Gohoes, in the county of Albany and State of New York, have invented certain new and useful Improvements in Needle and @il Guards for Sewing-Machines, of which. the following is a specification. V

Reference may be had to the accompanyingdrawings, and the reference characters marked thereon, which form a part of this specification. Similar characters refer to similar parts in the several figures therein.

The principaipbjects of the invention are to prevent the soiling of the work by oil from the resser-footbar or the slidewaybearing for said bar; and to prevent the fingers of the operator from injury by the needle of the machine.

Other objects will appear in connection with the following description.

Figure 1 of the drawings is a view in front elevation of a broken-away portion of a sewing-machine showing my attachment mounted upon the pressehfoot-bar which is in raised position, and with the needle-guard in front of the needle.

Fig. 2 is a view of the same in side elevation as seen from the left-hand side of Fig. 1.

Fig. 3 is a horizontal cross-section of the same taken on the broken line 8-3 in Fig. 1.

Fig. e is a View in perspective of the attachment detached from the machine.

Fig. 5 is a view in perspective of the oil absorbing felt washer detached.

Referring to the drawings wherein the in vention is shown in preferred form, 1 is a part of the head of a sewing-machine having the usual vertically reciprocatory presserfoot bar, 52, carrying a presser-foot, 8, -cooperative with the bed-plate, 4, adjacent to the feed-bar, 5.

The presser-foot-bar in the operation of the machine occupies the position indicated by dotted lines in Fig. 2, in which position it holds the work upon the bed-plate, 4:, adj acent to the feed-bar.

The presser-foot bar is capable of being raised in the usual manner to the position shown by solid lines in Fig. 2, to facilitate the insertion of the work, the bar having a vertical slideway-bearing in the headyl,

in the usual manner.

To facilitate the movement of the bar in its bearing, the bearing is frequently lubricated, and the lubricant frequently runs down along the bar and soils the work which is passing through the machine;

One feature of my attachment comprises a cup, 6, encircling the nresser foot bar, and detachably secured thereon by means of a Screw, 7.

Within the cup, 6, I place oil-absorbing material, 8, which for certain purposes of the invention may be any substance which will readily take-up or absorb the oil which runs down along the presser-foot-bar from its bearing in the head, 1.

The absorbent-material, 8, is preferably in the form of a divided fel -washer, as shown in Fig. 5, whereby the washer can be opened to permit it to be applied to or removed from the presser-foot-bar without removing the cup, 6, from the bar.

The washer, 8, will thus take up or absorb any oil whichotherwise would tend to run down to the lower end of the presser-foot bar with danger of soiling the work.

When the washer, 8, has become saturated with oil it can readily be removed and a clean washer inserted in the cup, 6.

The machine also has the usual needle-bar, 9, and needle, 10, the needle-bar being vertically reciprocatory in the head, 1, in the usual manner.

To prevent the fingers of the operator from being injured by the needle, I provide a needle-guard shown formed of a single piece of wire having an upwardly extending needle-guarding loop, 11, adapted to occupy a position just in front of the needle and having a needle-guardingmember, 12, extending rearwardly from the outer leg of said loop, and a lateral extension, 13, terminating in a vertical spindle, 14, which occupies a bearing'aperture, 15, extending vertically through an arm, 16, offset from the air,

The spindle, ii, is secured in the bearingaperture, 15, by means of a screw, 17.

The spindle, 14, is rotatively mounted in the bearing-aperture, 15, permitting the needle-guard to be swung from the position shown by solid lines to that indicated by dotted lines in Fig. 3, when it is desired to have access to the needle for threading the same or for inserting or removing the needle.

When the needle-guard is swung to the position shown by solid lines it is just in front of the needle and prevents the fingers of the operator in feeding the work to the needle from engaging the needle or passing beneath the needle.

The rearwardly extending member, 12, prevents the fingers of the operator from guide for the movement of the needle-guard into operative position.

What I claim as new and desire to secure by Letters Patent is a The combination with the presser-foot-bar, needle-bar and needle of a sewing-machine; of a bracket mounted upon the resser-footbar and provided with a bearing-aperture extending vertically therethrough; and a needle-guard formed of a single piece of wire bent to form an upwardly extending needle-guarding loop having a needle-guarding member extending rearwardly from the outer leg of said loop, and a lateral extension from the other leg of said loop terminating in a vertical spindle rotatively mounted in the bearing-aperture in said bracket; and a screw for securing said spindle in said bearing-aperture. v In testimony whereof I have hereunto set my hand this 22nd day of August, 1919.

WALTER J. BEATTIE.
