COMBINED PRESSER FOOT AND NEEDLE GUARD.

Application filed September 21, 1920, Serial No. 411,726. Renewed February 23, 1928.

To all whom it may concern:

Be it known that I, HERMAN Trn, a citizen of the United States, and a resident of Valley Stream, county of Nassau, and State of New York, have invented certain new and useful Improvements in Combined Presser Feet and Needle Guards, of which the following is a specification.

This invention relates to improvements in combined presser foot and needle guard.

One of the objects of this invention is to produce a presser-foot device for sewing machines, and particularly for sewing machines adapted to operate on jute bags and the like, which will not only perform its usual pressure-applying function, but will also serve as a guard for the point of the needle, and furthermore will enable the retention of a greater supply of lubricating material for the needle than has heretofore been possible.

More particularly, my invention comprises the use, in combination with a presserfoot base-plate having a needle hole therein of a finger-protective housing erected upon the said base-plate above and surrounding said needle hole in such manner as to permit the point of the needle to travel in its reciprocating movement above the base plate in order to make the stitch through the material and still remain within the housing so that the operators fingers will be prevented from moving beneath the needle point. A guard is thus provided for the needle at the point of operation which will prevent injury to the operator without hinderin g the work. Preferably the said fingerprotective housing extends to opposite sides of the needle hole and connects at its forward edge with the usual upwardly inclined front portion of said presser foot, the top of said housing preferably lying in sub stantially the same horizontal plane as the top edge of the upwardly inclined portion of the presser-foot, whereby ,the point of the needle during reciprocation will be permitted to rise above the base plate of the presser foot to form the sti'tch but will never rise above the protective housing onthe baseplate of the presser-foot, which housing is provided in a depression between the front end of the said base plate and the operating hub spindle, will be out of the way and will in no way hinder the operation of the machine, while at the same time the point of the needle will, as aforesaid, at all times during operation be guarded; the operators fingers will be protected against injury by the point of the needle.

W i'th these and other objects in view the invention comprises the combination of members and arrangement of parts so combined as to co-act and cooperate with each other in the performance of the functions and the accomplishment of the results here- 1n contemplated, and comprises in one of its adaptations the species or preferred form illustrated in the accompanying drawings, in which Fig. 1 is a side elevation of a presser foot and needle guard embodying my invention;

Fig. 2 is a plan view of the presser foot and guard shown in Fig. 1;

Flg. 3 is a section on the line 33 of Fig. 2;

gig. 4 is a section on the line 44 of Fig. 2; an

Fig. 5 is a section on the line 5-5 of Fig. 2.

Referring now to these drawings. 1 indicates the base-plate of my combined presserfoot and needle-guard which, as shown, is provided at its front end with the usual upwardly inclined entrance portion 1 and has a needle hole 1 of suitable form or configuration and suitably placed contiguous to said upwardly-inclined entrance-portion 1. brected upon the base plate 1 above and surrounding the needle hole 1 is a protective housing 2 which, as shown, comprises side walls 2 -2 and a roof 2 which preferably extends substantially in the same horizontal plane as the end or nose 1 of the entrance portion 1" of the said base plate of the presser foot, and the roof of said housing is provided above the needle hole 1 with a needle hole 2, the axis of which needle hole is preferably in registry with the point of the needle 10. The roof 2 of the said housing is of Suficient height from the base plate to enable the stitch to be made through the material without having the needle point, in its travel, rise above the roof 2 and is preferably sufficiently low to extend below the eye 10 of the needle when the same is at its highest point in its upward travel so as to enable the needle to be threaded readily while still protecting its point. Said roof so preferably extends below the needle eye from the nose 1 as aforesaid rearwardly to a point contiguous to the presser-foot hub 4 which, as

nection with the base plate. The said hub a is provided with set screws 6 and 7 to permit rigid connection to a vertical spindle 8 which is provided with suitable pressure and operating devices, not shown.

From the foregoing it will be seen that I have rovided a combined presser-foot and guar for the point of a needle and furthermore that my improved combined presserfoot and guard, while permitting theneedle to be effectively threaded and operated to form the stitch, will also effectually guard the point of the needle during'its movement above the base-plate to make the stitch and will thus prevent the entrance of the operators finger between the needle point and the said base plate of the presser foot and consequently prevent injury to the operators fingers. Furthermore the housing is formed in a depression between the nose of the base plate and the hub, it is out of the way and will in no way interfere with the threading or operation of the needle but on the contrary will permit ready threading, reciprocating and the formation of a stitch by a movement above the base late of the said presser foot within the houslng but at the same time will, as aforesaid, prevent the entrance of the o erators fingers into the space between t e presser foot and the point of the needle which is necessary for the formation of a stitch through the material as aforesaid.

Having described my invention I claim 1. A combined presser-foot and guard for the point of a needle embodying a presserfoot base-plate having a needle-hole; means for connecting the presser-foot base-plate to the operating-mechanism therefor and an enclosing housing erected on said base-plate above and surrounding said needle hole comprising spaced side walls and a horizontallydisposed finger-protecting roof between such side walls provided with a needle-hole havin its axis substantially coinciding with the axis of the needle.

2. A combined presser-foot and guard for the point of a needle embodying apresserfoot base-plate provided with an upwardlyinclined entrance-portion and having a needle-hole; means for connecting the presserfoot'base-plate to the operating-mechanism therefor and an enclosing housing erected on said base plate above and surrounding said needle hole comprising spaced side walls and a horizontall disposed fingerprotecting roof disposed in substantially the same plane as the nose of the inclined entrance-portion of said base-plate, said roof being provided with a needle hole having its axis substantially coinciding with the axis of the needle.

3. A combined presser-foot and guard for the point of a needle embodying a presserfoot base-plate provided with an upwardlyinclined entrance-portion and having a needle-hole; means for connecting the presserfoot base-plate to the operating-mechanism therefor and an enclosing housing erected on said base plate above and surrounding said needle h'ole comprising spaced side walls and a finger-protecting roof disposed in a substantlally horizontal lane below the eye of the needle when at tile highest point of its upward travel but above the point thereof, said roof being provided with a needle hole having its axis substantially coinciding with the axis of the needle.

In witness whereof, I have signed my name to the foregoing specification in the presence of two subscribing witnesses.

HERMAN TYD.
