To ail whom it may concern:

Be it known that I, ROBERT S. HILTMANN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and 5 usel'ul Needle-Guard for Sewing-Machines, of which the following is a specification.

My invention relates to certain new and usel'ul improvements in needle guards for sewing machines, which is fully described and explained in' the speeifi- 1.0 cations and shown in the accompanying drawings, in

which Figure 1 is a perspective view of a portion of a sewing machine with my improved needle guard in place; Fig. 2 is a side elevation of the parts with a portion of the needle guard in place; Fig. 3 is a view of the needle guard alone, the needle guard being shown in its closed I position; Fig. 4 is a similar view of the needle guard I in its opened position; and Fig. 5 is a front elevation of the needle guard in its opened position, looking in the Referring to the drawings, A is a. portion of the frame of a sewing machine, from the lower end of which pro:

jects a vertically reciprocable needle bar, B, at the front, and a vertically reciprocable pressor foot bar, 0,

The needle bar, B, carries a needle, I), hold in place by means of a set screw, 5 and the presser l'oot bar, 0, carries a presser foot, 1:, held in place by a set screw, a, said prossor foot comprising a vertical portion connected to (he presscr l'oot bar, a horizontal 2O direction of the arrow, 5, in Fig. 4.

portion lying beneath the needle bar and perforated 3 5 all oi' old and woli known construction and their-par ticular form andnrrangement is capable of the greatest modification.

The parts as herein illustrated are substhntially identical with corresponding parts oi the fiVlmelei" &

40 Wilson sewing machine now upon the market, and

they are illustrated in this form because I happen to have applied my noodle guard .more particularly to this machine. f

My improved needle guard consists of [our portions connected together, a renrportion, D, adapted to be connected to the m'essor foot bar, two side portions, fl) and F on the right and left hand sides respectively, and suitably supported by said rear portion, D, and a locking device, G. The rear portion, .l), which is ol sheet metal, is provided with a noich, 1!, which can be slipped over the presser loot set screw, 0 so that the structure can be held in place by loosening said set screw, placing the rear portion in the position shown in Fig. 2 of the drawings, and tightening up the set portion, D, and the same has an upwardly projecting v integrally formed tongue, 0, in position to lie adjacent to the reciprocable needle bar, B. The side portion has also a lip,.e, turned at right angles to the plane of the side portion and adapted, when the side portion is swung forward, to lie in front of the forward point or tip of the presser foot, and when so positioned to slant diagonally forward and upward. as shown in Fig. 2, so as to direct the cloth to be operated upon into proper position, and notto interfere in any way with its passage beneath the presser foot.

The left hand side portion, F, is in general similar to the right hand portion, E, except that the upwardly projecting tongue, e, is omitted, and in its place an upwardly projecting, outwardly turned semi-cylindrical b82l(l,f, is supplied. This head is of such form and dimensions that when the left hand side portion, F, is swung up adjacent to the needle bar, as shown in Fig. l, the needle set screw, 1), willlie Within the bead as illustrated. The left hand side portion, F, is provided, like the other side portion, E, with a lip, f, adapted to overlap the lip, 1*, as illustrated, so that the two lips together completely inclose the tip of the pressor foot and the adjacent parts.

It will also be seen that the outlines of the two side portions are such that wh in the parts are in thc position shown in Fig. 1, it w ll be practically impossiblc for the user oi the sewing machine to gel a linger into position to be injured by the needle.

The locking device, G, is made in the form of a U- shapecl bail of wire, pivoted at its center To the rear portion, D, of the needle guard. \Vhcn the parts are swung up to the position illustrated in Fig. 1, this locking device can be rotated upon its pivot and its arms will swing down outsidc or the two side portions of the needle guard as shown in said ligure, thereby locking them firmly in position, to lor m a complete iuclosing structure for the moving parts olihe machine. it will be seen that by this construction I scour-e a needle guard which makes the accidental injury or the user by the needle. a practical impossibility. Furthermore, the two side portions of the needle guard can'be'swnng threaded or to permit one needle to be suhstilutcd [or is in no way interfered with.

Nhen the needle guard is in its opened position, as shown in Fig. 4, the tips of the side portions projcct forward and necessarily presen trather sliarp points to 'sition the needle guard will very seriously interfere with the operation of the machine. Thisleature of operation practically forces the user of the machine, when theneedle guard is in place, to keep the same in its The right hand side portion, E, is pivoted to the rear apart with the greatest ease, to permit the needle to be.

another, so that the practical operation oi the machine the cloth to be operated upon, so that when in this poclosed position at all times when the machine is in use,

'and I consider this feature '1 extreme importance.

It will be observed that the side poillions of the device are provided with perform-ions of considerable size. The purpose of these perforations isto permit as much light as possible to be admitted to the interior of th guard, so that the operator can see the Work which is living done as well as if the guard were not in position.

It will also be observed that I extend the side por-' tions of the guard upward in the tongue, e, and the bend, f, on the two sides of the moving needle bar.

This construction is such that it is impossible for the user to get the fingers between the lower end of the needle bar or lhe needle bar set screw and the upper end :11 the guard, so as to be injured, as they can be in certain of the guards heretofore known. 7

i realize that considerable variation is possible inthe details of the construction without departing from the spirit of my invention; therefore I do not. intend to limit myself to ihe specific forln herein shown and described.

I regard as new and desire to secure by Letters Pat" enlz:

1. hi :i ('l-(lll gourd. portions which lie to the front of and to tlusides. of the needle, and portions which extend upwurils al ng; the line of the needle bar, above the set screw lllll' 'lll mu] lie outside the some.
