T all whom z't mag; conoern:

Be it known that I, HENRY H. GARRETT, 0f the 0ity and county 0f Albany, State 0f New York, have invented 0ertain new Improvements in Pins and Eyes f0r Molders Flasks and I hereby deelare that the following is a deseription thereof, reference being had t0 the accompanying drawings forming a parb 0f this specification, in Whi0h- Figure 1 represents a seetion 0f two parts ofa flask, With the steadying-pin and eye, embodying the improvements in tl1is inventi0n, and attaehed thereto. sectional view 0f the steadying-pin and its key, secured in place in the wo0d 0f the flask. Fig. 3 is acros s-seetional view 0f the eye a'nd ifs key, secured in plane in be side of the flask. Fig. 4 is a eross-sect-ional view haken als lines N0. 1 inliigs. 2 and 3.

My invention relates 130 steadying-pins and eyes for molders flasks,and consiscs in the combination, with a plate-braeket earrying tl1e piu 01 eye, 0f an attaehing-pin, having a spm on its wood side a1; sonne point back of t-he seid. plate-bracket, and a key, in such a manner that, when the attaching-pin is inserted in a hole made in the side 0f the flask and the key is driven in the .same hole 011 the opposite side from the spur, the said Spur may be clriven 0r sank int0 the w0od. in a direction"fltg;ight angles witl1 the holding-pin the obje0t 0f this invention being 130 secure the plate-bmeket and. its pin 0r eye firmly t0 the sides of the fiask, and prevent its shifting 01 displaeement, by a key that n1ay be readily removed, that, in the event 0f a, pin 01' eye being broken the molder may, hy the use 0f a new duplieate pie0e, after removing the old piece by a withdrawal 0f 1she key, replaee the broken pieee, (und thereby obviate all neeessity f0r its removal the carpenters shop f0r the necessary repair, as DOW required.

T0 enable ot-hers skilled in the art make and use my invention, I Will proceed 130 describe it in reference '00 the drawings am]. the letters 0f reference marked thereon, the sa1ne letters indicating 1ike parts.

In the drawings, A represents the stemdyingv pin, cast solid. with the plate-bracket B, and

soarting from the face 0f the same in the manner shown in Figs. 1 and 2. 0 represencs the eye, also 0ast t0 the similar plate-loracket B, an'd standing ab right angles from the same, es in FigS. 1 and 3. Made With the platebraeket B, employed With both the piu A and eye B, is the' lip a, made soli'd with said. braeket, and 0n the side opposite from the said pin 01 eye employed. Gast; s0lid with ehe plate-braeket B, and ab the end opposite from the lip a, is the abtaching-pin D, Figs. 2, 3, and. 4, made with a plain beaming-surface, x, am]. a little shorter in length 0112m tl1e thiekness 0f the W00d. of the flask int0 whieh it; is so be introdueed. The terminating end 0f the said attaehingpin is made with ehe spur 0 011 its side toward the lip a, or pin, er eye, the said attaehing-pin is 110 secure. E is the key, made substantially as sh0wn in Figs. 2, 3, and 4, with plain bearing surface xand With a partiallyinelined surfa0e, z, as shown in the said figures. The said key is made with tl1e head F having a lip, e, exte nding laterally a little 01111 from the body 0f Ehe key. The head 0f the said key is preferablymade With a, form that will 00rresp0nd With the plaebr&eket B, for the appearance 0f a finished termin'ation 0f the same, as shoWn in Fig. 1. T0 seeure the pih 0r eye in place With the sides 0f the fl ask, a hole, G, is bored into the wood of the flask ab a proper point', with a diameter about equal 110 that of the key E and pin D. The attaehing-pin is then inserted With its Spur toward. oho meeting-surfaee 0f the fiask, when tl1e key is also inserted am]. driveu in, when the inclined. surfaee z Will forc'e the surface w 0f the key down on tl1e surface x 0f the attaching-pin, and cause the spur 130 sink int0 the w00d, as

shown in Figs. 2 zmd 3, and the wh0le will be firmly seeured.

When it is desired to replaee a br0ken pin 01 eye tl1e key is be withdrawn, which may be effeetecl by inserting any suitableinstrument beneat-h the head F and prying 011 the sanr1e, when the platze, with its attaching-spur, may be readily removed, when the old broken pin 01 eye may be replaced loy a new dupli- 0ate pieee.

If delsired, an inclined .rib, exten'ding ft0m the reair side of the plate-brackeb 120 therear end of the attaching-pin, ma-y be employed in lieu of the Spur, as shoWn by do'tated lines in Figs. 2 and 3, in which case a porbion of 'che wood am the lower side of the hole Ggna.y be

rem0ved by a chisel 01' gouge 130 corr6si otxd with the said inclined. rib, which rib would. operate' substantially the sa.meas the spur for holding the device in place am). secure, when the key is driven in place.

By the improvements in this invention the steadying-pin 01 its eye may be seeurelyheld attaehed. 110 the w0od of the flask without the aid-of screws, bolts, 0r rivets, as heretofore re-
