DEVICE FOR SETTING LAClNG-STUDS.

SPECIFICATION forming part of Letters Patent No. 329,264, dated October 27, 1885.

Application filed Ann 29, 1885.-

To all whom it maylconcern:

Be it known that I, MELLEN BRAY, of N ewton, in the county of Middlesex and State of Massachusetts, haveinvented certain new and useful Improvements in Devices for Setting Lacing-Studs, of which the following, taken in connection with the accompanying drawings, is a specification.

My invention relates to devices for setting lacing-studs, and is designed more especially for setting glove-lace studs provided with a concavo-eonvex washer, such as is described in another application of mine filed in the Patent Office at \Vashi'ngton, District of Columbia, February 14, 1885, and numbered 155, 870; and it consists in certain novel constructions, arrangements, and combinations of parts, which will be best understood by reference to the description of the drawings, and to the claimsv to be hereinafter given.

Figure 1 of the drawings is a side elevation of the stud-setting machine embodying my invent-ion. Fig. 2 is acentral vertical section of a portion of the machine through the axis of the setting-tools in position for commencing the setting, with the stud to be set and its washer in position to be acted upon by the descending setting-plunger. Fig. 3 is a similar section of the lower setting-tool with the work thereon and. the stud completely set. Fig. 4 is a plan of the lower setting-tool with the work removed, and Fig. 5 is a front elevation of the same.

scale.

In the drawings, A is the base of the machine, from which rises the goose-neck A, carrying in its end the setting-plunger B, arranged to be moved upward by a spring, (not shown,) and to be depressed by the lever O, to which motion is imparted by the rod D and a. treadle-lever, (not shown,) to which the lower end of said rod is connected, all of which is old and of well-known construction, my present invention being confined to the setting-tools and the means employed to facilitate the insertion of the stud into the pocket for receiving it. In the base of the machine, and in axial line with the setting-plunger B, is set the anvil-socket a, inwhich is fitted the steel anvil b, having its upper end cupped out to fit the convex outer surface of the stud-head, and arsenal No. 163,808. (No model.)

ranged to be slightly adjusted in its socket by means of the screw 0, as shown in Figs 2 and 3. The anvil-socket a has formed upon its upper ,end the collar a, to which is fitted the cylindrical sleeve (1, provided at its upper end with the outwardly-projecting collar d, and at its lower end with the inwardly-projecting annular lip d which fits to the body of the anvilsooket below the collar (6, as shown in Figs. 2 and 8. The upper end of the sleeved has formed therein a shallow dovetailed groove, in which is fitted a thin steel plate, 6, in the upper face of which is formed the annular curved bottomed recess 6, having an inner diameter about equal to the diameter of the base-collar of the stud f to be set, said plate having a portion of its front edge cut away to theinner periphery of said recess, as shown at e"in Fig. 4, in order that the stud to ,be set may he slipped upon said plate fill its base-collar rests upon its upper surface, with its center or axis concentric with said annular recess 6, while the outer head of the stud is beneath the plate e and resting in the concave end of the anvil b, as shown in Figs. 2 and 8. The plate 6 is made of a thickness just equal to the desired distance between the outer head and the base-collar of the stud, and the sleeve (1 is forced downward, so as to clamp the outer head of the stud f between the cupped end of the anvil b and the under side of the plate 6 by the tension of the coiled spring 9, surrounding the body of the anvil-socket a between its collar a and the annular lip d of the sleeve d, as shown in Figs. 2 and 3.

In order to place the stud f upon the plate 6 in the proper position to be set, the sleeve d and plate e must be lifted against the tension of the spring g, which may be done by pressing upon the rear end of the lever E, pivoted at h to the goose-neck A, and having its front. end forked, so as to engage with the collar 01 upon two opposite sides of said sleeve. The upper end of the sleeve d has a recess, d, formed in its front side to facilitate the insertion of the stud to its proper position upon the plate 6 and its removal after being set. By this construction and arrangement of the anvil and its accessories for holding the stud in position thereon a solid bearing for the stud is obtained to receive the blow of the clinching-tool, the outer surface of the head resting in the cupped upper end of the anvil b, and the plate filling the space between said head and the base-collar, so that when the 5 blow ot'theclinching-ttml isgivcn tothe shank '0! therivet toclinch it the blow istmnsinitted through 'Lhcstnd -'to the anvil 6, no straiii'being applied to the plate 0, except a crushing strain.

to Heretofore, as far as I know, in setting studs having solid heads the whole strain of clinch:

ing the shank of the stud-and that a tensile strain-has been received by the plate which entered between the outer head and the basecollar, which has been found to be objectionable, particularly when setting studs designed to be used with a lacingcord of small size, as

i for glove-laeings, for the reason that the plate could not be made sullicient-ly strong to resist the strainfor any considerable time, which objection is entirely overcome by my inventiou. Another advantage of this arrangement is that if from any cause the space between the outer head and base-collar of the stud is too great, the act of setting the stud reduces said space to the required standard dimension, and uniform with all the studs set upon the same plate.

. It is obvious that a thicker or thinner plate may be substituted for the plate 0 shown in the drawings. according to the size and style of stud to beset, with which change and a proper adjustment of theauvil b by the screw I I 0 my improvement, so far as described, is adapted to set the ordinary tubular-shanked lacing-stud; but in order to facilitate the setting of my improved glove-lace hook or stud with its coneavoconvex washer. which forms the subject-matter of anotherapplication, tiled 40 February 14, ISSI, Serial No. 155,870, 1 attar-h to the-clinchingtooli the sleeve j, ar ranged to surround and project below the lower end of the clinching-tool i, and to be moved upward thereon against the tension of the spring 7:, said sleeve being guided in its vertical movennaits'aml prevented from thin ing upon its axis by the pins 1 l, projecting radially from the enlarged part of the clinchingtool ithronglrslots m m, cut through the o walls of the sleeve j, all as shown in Fig. 2.

hen the stud has been placed in position-' upon the plate 0 with its shank upward. and the material in which the stud is to be set and the concavo convex washer n are placed upon the shank as shown in Fig. 2, ifthe settingplunger be moved downward, the sleeve j first comes in contact with the washer u and forces it downward into close contact with the material and the material' into close contact with the base-collar, and by virtue of the concave form of the side of the washer n,which is next to the material, the material is bent down around said base-collar and into the annular recess 0', as shown in Fig. 2, and then the clinching-tool i descends and clinches the shank over upon said washer, while the sleeve j remains stationary.

When it is desired to set studs without the eoncavomnvex washer, the annular recess 1' may be dispensed with, the plate r having its upper side made a plain tlat surface like its under side. u

What I claim as new. and desire to secure by Letters Patent of the t'nited States, is-

1. Asameans forholdingalacing-studwhile being set and receiving the blow ofthe settingtool, a stationary anvil having its upper end shaped to fit the outer surface of the head of the lacing-stud, in combination with a plate arranged above said anvil and adapted to till the space between the outer head and the basecollar of the stud to be set. and a spring arranged to act upon and pros said plate toward said anvil to clamp the head of the stud between it and said anvil, so that the shock of the blow of the clinching-plunger shall be transmitted to the stationary anvil instead of being received and sustained by said plate, substantially s described.

2. The combination of a stationary anvil havingits upper surface shaped to fit the outer siirfircc ofthe outer hcadof the stud to be set, a slecve-surrouinling said anvil, a removable 'plate secured-to and extending across the top of said sleeve and arranged to till the space between said outer head and the base-collar of said stud, and a springarmnged to press said sleeve and plate downward so as to clamp the head of the stud between said plate and anvil, substantially as described.

3. The combination of the stationary anvil a b, the sleeve d, arranged to surround the anvil, and provided with the recess (1, the plate 4-,sccured to the upper end of the sleeve (Land provided with the recess!" and the notch v, and the spring all armnged and adapted to operate substantially as and for the purposes descrilwd.

4; The combination of the anvil a b, the sleeve d, provided with the collar (l'.the plate (secured to said sleeve, the spring and the lever 1'], all arranged and adapted to operate substantially as described.

5. The combination of the anvil a I). the sleeve 1!, the plate 0, the spring g, the clinching-tool i, the sleeve j, and the spring A, and mechanisnnas described,for imparting to said clinching-tool a reciprocating motion, substunt iall y as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
