To all whom t may concern:

Be it known that I, ALBERT V. J. IRELAND, a citizen of the United States, residing at Corona, city of New York, in the county of Queens 'and StateL of New York, have invented a new anduseful Stiletto 'or Pointed Pin' with an AdjustableGage ,fittnched for Piercing Holes into Material to be Emgage for holes ofvdifferent size -as easy and convenient as possible,'and to puncture the material and spreading the mesh of same without destroying said material. I-"obt'ain v these objects by a stilettoor pointedk pinconstructed as fully illustrated in the accom- Figure 1 is a general vview of the stiletto or pointed pin, and its applicationupon the material to be embroidered, stretchedand held within the ordinary embroideryhoops or frames marked 11. Fig. 2 isla; view taken from right hand side Fig. 1, and is partly in section to show notches 'or stopping grooves of the gage to set Isame for desired sized hole andV to prevent shiftingk of the gage (marked 12) without aid'of any set screws or clamping device. F igzfS is a cross section through gage or friction sleeve 12.

Fig. 4 is an enlarged front view of vrthe stiletto or pointed pin, similar to Fig'.y 1, but with gage 12" shown moved'A forward, eX- posingvto view the notches marked 8, 7 and 6. Fig. 5 is valso lan enlarged side'view of Fig. 4, and partialjsection on linel5-5 of Fig. 4, to more clearly showr the engagement of small tongues 13 of gage 12,; with the notches in pin'15, and which engagement positively prevents shifting of the gage, 4or away fromA stopping sleeve 12 farther Y pointed end of pin 15, insuring the piercing of holes of the size set. Fig. 6 isa cross section on line 66 of Fig. 4, showing more clearly how pin 15 is encircled and gripped under desirable elastic or spring pressure of the sleeve or gage 12 formed from aliat band of springy material. Fig.

7 is a side view of thestiletto or pointed pin with gage or sleeve'12 partly in section and radially turned upon the pin 15, disengaged from the notches by turning upon the smooth straight surface of the pin and shown as shifted forward under' slight elastic friction of the sleeve 12, so as to cover and protect the pointed end- 16 of pin 15.y Fig. 8 is a section'through attened portion of pin on line S-Sof Fig. 4.

.Similar numerals refer to similar parts throughout the several views.

11s seen fromA drawing this stiletto or pointed pin consists of two simple parts only, a pointed pin 15, notched upon its cy` 'K lindrical surface andmadeof any hard suit-; f i

able material, as metal, Celluloid, bone orV wood, ic. and a frictionally sliding sleeve,

made fromelastic material -or sheet, as metal, celluloid,&c. shaped to encircle the piercing pin 15, withdeslrable elasticv or 'springy grip, to prevent its falling o, and

with suflicient spring frictionto p'ermit,(if;

desired) the Vpiercing of smaller size holes in less `resisting thinner material, even with! out theV turning Vof the sleeve or gage 12 with' its tongues 13 into .engagement of notches 'marke-d, 1 to'and including 8, indicating size of holes. @The setting and turning of the gage 12 by the iinger flange-17 into the proper.notch,corresponding to size of holes to be pierced, becomes necessary inV Vpiercing larger holes or for. morev resisting or thicker material 'to insure positively againstfany 'shifting and change `offlioles.

F orf the usual embroidery or needleworky this piercing lpin 15 isabout'1/4 diameter,

4 to 5 inches long with a'pointed end 16 i about lg long with notches about 1/8 apart andr numbered 142-3 to and including"y mark 8,- so that for gaging and setting the' size of hole .pierceable by the setting, is by thisstiletto or pointed pin indicated'by the. lowest number eXpose'dbythe kgage 12, `as forfexample andas/shown'in Fig. 4,'wher`ek the lowest number 'exposed or opened to viewv'is'fshown as 6, it would, under the said proportions, indicate that the setting at 6 shown in Fig. 4,. a hole of 6/32 could be pierced, while if gage would be set that only number 1 notch would appear outside of gage, then a hole ofl only 1/82 could be pierced, or at any setting just as i many 1/32 of one inch diameter holes as the lowl `est number exposed by the gage indicates.

The end opposite to the taperedV or pointed end of pin 15 'may be shaped or formed 'differently to suitV tastes, and is not aecting the principal features, therefore only two of many possible forms of end areshown ico as in Figs. l and 4, rounded and grooved,

I or ribbon of suitable outline and material,

formed to encircle the pin 15, with desired kelastic grip upon the piercing pin, and is provided in one piece, with one or more tongues 13 of semicircular 4or other suitable Y shape orforin, and being directed inwardly.

and at same distance apart, so that all tongues of the gage come in contactand proper engagement with the-resisting faces ofthe notches in the pin 15, so Vas to posi-` tively hold gage to pin against the highest I resistance of piercing heavy or tough matelbroidering materials. Y n

Asthisimproved stilettoor pointed pin rial. hole setting, the gage needs only to be shifted toward the pointed end16 of pin 15, as

the tongues 13 will riot be resisted inl the movement of gage toward the tapered end, because the `notch surfaces in this direction are slanting, tending to liftl the tongues,

lilrepawls over theslant or incline under the assistance of ythe springy, Y yielding and slightly opening gagef12. But to increase Vsize of'hole from smallerV settings the flange 17 is tobe pressedlin the'direction 18 with the effect that the tongues hindering movement of gage from pointed endof pin become, by indicated turn of 1/4;l revolution,

ydisengaged from notches and brought upon 35V.

the smoothsurface of the pin as clearly shown in Fig..v 7, in Whichposition of the gage movement from or to` pointed end of pin ismade equally easy, While further turning vof the gage intoV engagement with notchesrwill then prevent sliding of gage *under` any resistance ,against` piercing any size or number of holes. This gage 12 .may

. or may not be provided with a front ange i 421Qto enlarge the stopping `surface of the l5` gage, .to prevent damagejto delicate em-` Y hasfonly'two parts whichare held together Y under springdfriction and. by notches, and

Toreduce size of holesfrom larger does not require set screws or other little parts to be fastened and loosened, it is to `be considered as another improvement and backward shifting, and so constructed as tol permit forward shifting without necessity of turning or rotating, but permitting backwardvshifting for change of hole-punching diameter, only by partial turn ofthe sleeve to disengage from the stopping tongues and notches. f

2. A stiletto or pointed pin with notches or rack in combination with a sleeve or gage encircling said pin', arranged to permit lon-4 gitudinal sliding without necessity of turning.; saifdvsleev'e having one or more tongues to engage with notches to lock the gaging sleeve vat the size ofrhole ,desired to be plerced.

3. A stiletto or pointed pin with notches spring pressure grip permitting longitudinal shifting without turning and having tongues or pawls to engage with and against notches or the rack of the pointed pin.

- 4. A stiletto or pointed pin with notches or rack in combinationwith a ksleeve having astopv flange at the front and a side ange at its side and encircling the -pin with inward spring pressure permitting sliding and provided with tongues or vpaWls engaging with'the notches or rack of pointed pin.
