STILETTO.

Application led February 15, 1923.

This invention relates to embroidery in-A struments, awls or stilettos in general and particularly to a kind which is adjustable.

rlhe prime object of my invention is t provide a handy inexpensive and eiiciently working article, which may be readily fitted to the operators hand, and which is provided with a particularly designed finger rest so as to permit the ingers of the operm ator to press the device against the clot which is to be pierced. y L

Another object of my invention is to make the parts comprising the article smooth and handy Vand without objectionable obstructions.

Another object oi' my invention is to provide Within such device an adjustablemember adapted not only to limit the piercing stroke of the device but at the same time serving as a protection against injury to the operator when carrying the device and when the latter is not in use.

The foregoing and still further objects will be more fully apparent from the following description `and the drawings forming part of this speciication, and in which:

Figure 1 represents a piercing member.

Figure 2 is the outer sleeve member partially in section.

Figure 3 the inner sleeve member partially in section.

Figure 4 represents an assembly in longitudinal cross-sectional view showing the way it is applied.

Figure 5 is a modified form of a part of the adjustable inner sleeve member.

Figure 6 is a cross sectional view taken on line 6-6 oi Figure 4.

Referring to the drawings numeral 10 dedevice, which is substantially cylindrical in shape and tapering at one end as indicated at 11 to a sharp point indicated at 12. At the opposite end of the piercing member there is provided a head or knob 13 which is preferably knurled. Adjacent to the head there is provided a reduced threaded portion 14, which is adapted to engage an internally threaded outer sleeve 15 at the latters upper end. V

Sleeve 15 comprises a generally cylindrical member tapering somewhat at its lower portion 16. Adapated to also engage internally threaded outer sleeve 15 at its lower end there is shown in detail in Figure 3 the notes the piercing or pointed member of the f Serial No. 619,307.

inner sleeve 17 provided with a threaded head 18 and a substantially conical enlargement 19 serving as a linger rest when pressure is to be applied with the article against the material to be pierced.

In operation the inner sleeve 17 is set in desired relation. to outer sleeve 15 and the pointed member 10. By so doing the device may be set to pierce holes of any desired diameter. It is evident that the adjustment for a larger hole may be made by screwing the inner sleeve into the outer sleeve, thereby increasing the distance between point 12 and the face 19 ot' enlargement 19. By working sleeve 17 in an opposite direction the hole capable of being made by the piercing member kwill be smaller.

lVhen sleeve 17 is brought out further until threaded head 18 .becomes flush with the edge of thelower tapered end' 16 of 7J outer sleeve 15, pointed end 12 of piercing member 10 will be in alinement with the face 19 of the enlargement 19 of the outer sleeve. In this position the article may becarried in a pocket without injury to the bearer.

While I have shown in the drawing a particular form of my device comprising comparatively large elements, beA it .understood that the same objects andthe same advantages may be attained by making the article from very thin tubing as suggested in Figure 5, where the head 119 of Louter sleeve member 17 is shown to be made of a hollow form and is provided with an aperture 20 through which the pointed member 10 vmay be passed. f o

Similarly the pointed member 10 and sleeve member 15 may be drawn from tubing material.

It is obvious that only the pin portion of the pointed member is to be made suiiiciently strong to resist the wear and tear to which it is subjected while the remaining parts may be made of any suitable tubular material and provided with means for adjusting the parts relative to veach other, as desired.

While I have shown a specific form of my device, be it understood that changes or improvements may be made within the scope of my invention, for which I claim:

A new article of manufacture, comprising a central pointed member having a knob at one end and a. threaded port-ion adjacent to said knob, an outer sleeve member threaded internally and engaging at one of its ends to said outer sleeve and relativerto Said Cen. Y the threaded portion of said central memtral member. Y ber, an inner sleeve member having a thread- Signed at New York, in the County of 10 ed portion at one end and an enlargement New York7 and State of New York, this 13th 5 for a finger rest at the other end, the inner day of February, A. D. 1923.

sleeve member engaging said outer sleeve member and adapted to be adjusted relative CHARLES E. VINKLER.
