LEON S. LEON, OF CHICAGO, ILLINOIS.

EMBROIDERY-PIERCER.

Specification of Letters Patent.

Patented Mar. 29, 1910.

Application filed July 26, 1909. Serial No. 509,605.

To all whom it may concern:

Be it known that I, LEON S. LEON, a citi- Zen of the United States, residing at Chicago, Cook county, Illinois, have invented certain new and useful Improvements in Einbroidery-Piercers, of which the following, taken in connection with the drawing, is a description.

My invention has for its object the production of a piercer or stiletto designed to be used for perforating embroidery patterns in fabrics of various kinds.

Another object of my invention is to provide such an instrument with a shield or covering for the piercer that when it is not in use it may be folded or telescoped into a small space and the points protected.

A further object of my invention is to provide in the same instrument a piercer having two points, either of which may be easily adjusted for use with the same handle.

Other objects and advantages in my construction will be hereinafter more fully pointed out in the following description.

In the accompanying drawings I have illustrated what I now consider the preferred form of my construction, it being obvious that the size, proportion and material out of which the device is made may be varied without departing from the spirit of my invention, and in these drawings Figure 1 is a side elevation of my invention; Fig. 2

.is a vertical sectional view taken on line 2--2 of Fig. l, illustrating one end of the piercer in position for use; Fig. 3 is a view similar to Fig. 2 illustrating'the piercer in reversed position; Fig. l is an elevation of the piercer removed from the cylinder. Fig. 5 is a sectional view of a modification.

A represents a cylinder, preferably although not necessarily closed at one end thereof. An outwardly extending circumferential shoulder a surrounds the open end of the cylinder. An elongated slot a extends from the open end of the cylinder to approximately the middle of the cylinder as shown.

B is a piercer which is of slightly smaller' diameter than the inside of the cylinder. This piercer tapers to a point at each end thereof, the shank at one end b being round in cross section and adapted to make a round hole in the fabric, while the opposite end b is flat and adapted to make an elongated opening in the fabric.

o is a small interiorly screw threaded bore arranged in the body of the piercer B and 1n this bore is a set screw C by means of which the piercer is adjusted inside of the cylinder A. By inserting the piercer B into the bore of the cylinder A and tightening this screw the piercer is adjusted to the position wanted and securely held. By slightly loosening the set screw the piercer may be moved in the cylinder, but cannot be displaced on account of the shoulder a which will not allow the head of the screw to pass over it until it is further unscrewed for that purpose. When it is desired to use the opposite end of the piercer the user removes the piercer from the cylinder by loosening the set screw sufficiently to pass yover the shoulder a and out of the elongated slot a when 'the piercer ma be reversed and the opposite end exposec as shown in Fig. 3. By adjusting the screw along the slot a the point to be used may be extended as much or as little as desired below the slioulder a, said shoulder a acting as a gage in the use of the device. C is the fabric which the iercer is perforat1ng, Figs. l and 2 il nsti-ating the round point of the piercer adjusted to exygend through the fabric a portion of its bcngth, and Fig. 3 with the flat point of the piercer being used.

Vhen not in use the set screw C is loosened, the piercer is moved entirely inside of the cylinder or shield A and the screw tightened to hold it in position, when both points are protected and the instrument occupies much smaller space than those herctofore used.

Referring to Fig. 5 which is a modified form of construction, the cylinder D is open at both ends and is provided with an clongated openinfr l extending nearly to each end of the cylinder. rlhe piercer B and adjustinfr screw C is the same as that heretofore described. In this foiin the piercer does not need to be removed from the cylinder to reverse the point, but simply loosen the set screw C and move it toward one end or the other to expose the point it is desired to use. When not in use the screw is secured mediate of the length of the cylinder and both points of the piercer will be inside of the cylinder.

I claim l. In an embroidery piercer, the combination of a cylinder having an o en end and also provided with an elongate slot extendsaid 2. ln an einbro'i'lery piercer, the c'oi'nbina-V tion of a cylinder havingan elongated slot therein, a shoulder surrounding one end of cylinder, a. double-pointed piercer movable in said cylinder, and piercer-locking means carried by the piercer and movable radially of the cylinder for securing said piercer, said locking means also movable Within and Without the. plane' of said shoulder, said locking means and shoulder forining exit-preventing means for the piercer i When'said locking means is'located Within the planeof'tliev shoulder. 4

3. -ln an'embroidery piercer, the combination 'of a cylinder having an open end and also'provided with an elongated slot extending from said open end thereof, an vout-' Waidly-extending circumferential shoulder surrounding the open end of said cylinder, a double-pointed piercer, and locking means for adjustably securing` the piercer Within said cylinder, said locking` means coperatying, with said shoulder for preventing the removalv ofthe piercer from the cylinder.

l.. In an embroidery piercer, the combination of a cylinder havingl an elongated slot therein, a should-.er surroundingone end of the cylinder, a double-pointed piercer movable iii said cylinder, and a locking,` member movable in and out of alinement with the periphery of the shoulder for adjusting the opeiatiirg` point of said piercer, said locking member and shoulder forming a re-' moval-preveiiting means for the piercer when said member-is located Within the plane of the shoulder.

In testimony whereof I have signed this specification in the `presence of two subsciibing Witnesses.
