I MACHINE FOR SETTING LACING-HOOKS.

SPECIFICATION forming part of Letters Patent No. 526,295, dated September 18, I894.

' Application filed March 21,1894. Serial No. 504,486. (No model.)

To all whom it may concern} I Be it known that I, ISAAC E. CHANDLER, of

Providence, in the countyof Providence and State of Rhode Island, have invented certain new .and useful Improvements in Machines for Setting Lacing-Hooks; and I hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification.

This invention relates to machines for attaching lacing studs to boots and shoes or other articles, and it has for its object to provide a simple, durable, and effective means for feeding such studs to position for attachment, rigidly supporting and holding the studs while they are being attached, and positively moving each stud with the article to which it has been attached, forward from the point of attachment, before the next stud reaches said point, so that the studs will be properly spaced and each stud prevented from being injuredby the setting devices.

To this end, the invention consists in the improvements which I will now proceed to describe and claim.

Of the accompanying drawings, forming a part of this specification,-Fignre 1 represents a side elevation of a machine embodying my invention, the stud reservoir being omitted. Fig. 2 represents an end view of the same. Fig. 3 represents a bottom plan View of the roadway, the yielding detent that secures the engagement of the studs with the spacing wheel, and the yielding plate or presser which forces the necks of the studs against the anvil portion of the roadway, the spacing-wheel being omitted, and a part of the supporting frame shown in section. Fig. 4 represents a perspective view of the stud spacing-wheel detached. 1

The same figures of reference indicate the same parts in all the views.

In the drawings-5 represents the supporting frame, which may be of any'suitable form, and as here shown has a recess 6 toreceive a portion of the work or article to which the lacing studs are to be attached, and a head 7 above said recess. The lacing studs to be set move down a roadway 27 from a reservoir (not shown) said reservoir being preferably anvil portion of provided with automatic means for delivering the studs tothe roadway in such position thatthe hook portions of the studs will bestride one edge of the roadway, the heads of the studs being at one side, andthe shanks .(here shown as eyelet-shaped) at the oppositeside of the roadway. The roadway is a -metal plate attached to a suitable support, as

by arms 26 26 affixed to the head 7, and exthe studs will slide downwardly on the roadway by gravitation to the spacing-wheel hereinafter described, suitable meansbeingemployed to prevent thehooks from leaving the roadway during their downward movement. In the present case, the roadway is located in such proximity to the vertical face of the head 7 that said face constitutes a guard to keep the studs in place on the roadway during their downward movement, there being anarrow space between said face and the inner edge of the roadway of sufficient width to accommodate the necks which connect the heads with the shanks of the studs, as shown in Fig. 1. i

The supporting frame is provided with a tends downwardly from the reservoir, so that horizontal bearing in which isjournaled a shaft 10, to one end of which is affixed the stud-feeding and spacing-wheel 21. Said wheel has pockets in its periphery, as shown in Fig. at formed to engage the heads of the studs which pass down the roadway, the wheel being rotated step by step as hereinafter described, and located so that each partial rotation will bring one of the pockets into engagement with the head of one of the lacing studs on the roadway, and cause a positive movement of said stud onto or toward the the roadway hereinafter described. y I

I The head 7 is provided with ayielding detent 15, adapted to arrest the column of studs on the vertical portion of the roadway and hold the lowest stud of the column in such. position that it will be engaged by the next advancing pocket, said detent being here shown as a bolt or stud having a convex outer end and fitted to slide in a socket in the head 7, a spring 14 being employed to project said detent into the path in which the necks of the hooks move from the roadway.

The rear end 23 of each pocket is preferably substantially at a right angle with the bottom of the pocket, so as to form a square shoulder adapted to positively engage and force forward a lacing stud, while the forward end 24 of each pocket is preferably beveled, as shown in Figs. 2 and 4. A part of the roadway is curved to conform to a portion of the periphery of the spacing-wheel, as shown in Fig. 1, and the curved portion terminates in a substantially horizontal extension of the roadway located below the spacing- -wheel. Said horizontal portion I term the anvil, because it co-operates with thesettingdie hereinafter described, in setting or clinching the shanks of the studs against the under side of the work. The studs are moved onto the said anvil by the spacing-wheel, and their necks are at the same time pressed against the inner edge of the anvil, to insure the correct position of the shanks upon the anvil, by means of a presser 13, which is a plate fitted to slide in a dovetail guide in the head 7 and pressed outwardly by a spring 13', said plate being arranged to bear against the necks of the studs that are moved by the spacingwheel onto the anvil.

18 represents the setting-die, which co-opcrates with the anvil above mentioned, in clinching or setting the shanks of the lacing hooks. Said die is fitted to move vertically in a socket in the projecting portion 8 of the supporting frame, and islocated below the anvil. Means are employed for vertically reciprocatin g the setting-die, said means as here shown being'a lever 16 pivoted at 16 to the supporting frame and provided at one end with an arm 17 which enters a slot 9 in the projection 8 and supports the setting-die 18. Said lever is oscillated by any suitable mechanism, and is provided with a pawl 19 which engages a ratchet 2O aflixed to the spacingwheel shaft 10, the arrangement being such that when the lever is moved in one direction it raises the setting-die without rotating the spacing-wheel; and when moved in the opposite direction, it depresses the setting-die and at the same time imparts a partial rotation to the spacing-wheel.

The operation-is as followsz-At each partial rotation of the spacing-wheel, a pocket therein engages the lowest stud of the column supported by the detent 15, and separates said stud from the column and moves it along the curved portion of the roadway. The extent of each movement of the spacing-wheel may be such as to bring the engaged stud at once to position over the setting-die; but as here shown, two movements of the wheel are required. When the wheel stops, the settingdie rises and upsets the shank of the stud held over it by the wheel upon the anvil, thus attaching the stud to the work, the latter having been previously inserted between the setting-die and the anvil. The setting-die then descends, and the spacing-wheel is given another partial rotation, which causes it to an extension of the roadway is necessarily somewhat slender, is supported by the spacing-wheel against the upward pressure exerted by the setting-die, and is thus prevented from yielding to said pressure. I prefer to attach a disk or collar 25 to the shaft of the spacing-wheel at the outer side of the latter,

the periphery of said collar being flush with that of the spacing-wheel between the pockets, the collar affording additional bearing and support for the anvil. I also prefer to provide the head 7 with a rigid projection or hearing 11 located over the spacing-wheel, with its under side in close proximity to the periphery of said wheel, said projection being adapted to support the spacing-wheel against upward pressure from the setting-die.

\ It will be seen that by forming the roadway to serve both as a roadway and an an- 1 vil, and arranging the spacingwheel so that it not only properly locates the studs upon the anvil but also removes them therefrom and supports the anvil against the pressure of the setting-die, I materially simplify the construction of the machine.

I claim- 1. The combination of a chute or roadway having its lower portion formed to serve as an anvil; a stud-spacing wheel located at one side of the anvil and provided with pockets to engage the heads of the studs of the road way; means for rotating said wheel step by step, whereby it is caused to first advance a stud to the anvil, then hold it rigidly upon said anvil in position to be set, and finally remove it from said position; and a reciprocating setting-die or plunger which co-operates with the anvil in setting the shank of a lacing stud thereon, the anvil being supported by the spacing-wheel against the pressure of the setting-die.

2. The combination of a chute or roadway having its lower portion formed to serve asrigid bearing on the frame of the machine arranged to support the spacing-wheel and anvil against the pressure of the setting-die.

3. The combination of a chute or roadway having its lower portion formed to serve as an anvil, a stud-spacing wheel located at one side of said anvil and provided with pockets to engage the heads of studs on the roadway, means for'rotating said wheel step by step, a yielding detent arranged to arrest the studs on the roadway and cause their engagement with the pocketsof the spacingwheel, and a reciprocating setting-die or plunger which co-operates with the anvil in setting the shank of a lacing stud thereon.

4. The combination of a chute or roadway hand. having its lower portion formed to serve as an anvil; a stud-spacing wheel located at one side of said anvil and provided with pockets to engage the heads of studs on the road- ISAAC E. CHANDLER.
