RECEIVER FOR RIVET-SETTING MACHINES.

SPECIFICATION forming part of Letters Patent No. 434,214, dated August 12, 1890.

Application filed February 27, 1889. Serial No. 301,306. (No model.)

To all whom it may concern.-

Be it known that I, JUDSON L. THOMSON, of Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Receivers for Rivet- Setting Machines, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

[0 My invention relates to an improvement in a receiver or pocket for rivet-inserting machines of the particular class set forth in the pending applications of Jacob J. Unbehend, Serial Nos. 295,027 and 301,307, and has for its object the production of a simple and effective device through which the plunger is operated, and to which a rivet is conducted bya suitable conveyer and then held thereby in the desired position, shank downward, in

the path of the plunger or other inserting mechanism and to this end it consists, essentially, in a receiver or pocket through which the plunger is operated, yielding jaws or rivet-holders adjacent to the discharge of 2 5 the conveyer for yieldingly holding the rivet and adapted to be disengaged therefrom when the inserting mechanism forces the rivet downward through the receiver into the desired position.

It furthermore consists in' the detail con- 3 5 to the accompanying drawings, forming a part of this specification, in which like letters indicate corresponding parts in all the views.

Figure 1 isan elevation of myimproved rivet-receiver or pocket in operative position upon a supporting-bracket, the die beneath the receiver and a detached portion of the conveyer being also illustrated. Fig. 2 is an end View of the detached pocket, illustrating the construction thereof. Fig. 3 is a like end view of the detached pocket, illustrating a modified form of the yielding shoulders for yieldingly grasping the rivet. Fig. 4 is a horizontal section taken on line 00 00, Fig. 2, illustrating the construction of the yielding 5o shoulders shown therein. Fig. 5 is a like horizontal section taken on line n y, Fig. 3,

illustrating the modified construction of the shoulders shown in said figure. Fig. 6 is a vertical section taken on line 2 .2, 'Fig. 2, the plunger being shown as having disengaged the yielding jaws from the rivet and having forced the rivet to the discharge of the pocket. Fig. 7 is a like vertical section, the rivet being shown as discharged from the pocket.

A represents the frame of my improved receiver or pocket, through which is actuated a plungerB or other suitable inserting mechanism for forcing the rivet through the said receiver or pocket into anydesirable article and interposed between the discharge a of the receiver and any suitable die or stop 1) beneath the discharge. The receiver or pocket A is supported in any desirable position upon a suitable bracket E, and has a to-and-frov movement upon said bracket in the same line as that of the rivet when being inserted.

When inserting rivets into any article, it is desirable that the same shall be fed directly to the said article in the desired position, shank downward. If considerable space intervenes between the discharge of the receiver and the article to be riveted, there is a liability of the rivet being turned over out of its true straight position when being forced through said intervening space. I seen,however, that the to-and-fro movement of the receiver or feeding-pocket allows articles of various thickness to be interposed be: tween the discharge a of the receiver and the stop or die D, since if the article is thin the receiver is actuated to contact with the same, or if it is thick the movement of the receiver is stopped by contact of the rivet with the article to be riveted. To allow this movement of the receiver A, I provide thereon the extension A, mounted upon the rod F, secured in lugs E of the receiver supporting bracket E. The conveyer G is mounted in any desirable manner, and preferably in a bearing-face E of the bracket E, and is provided with its discharge G, mounted in a cutout A of the receiver. The receiver is also provided with the cut-out a registering with the feeding-slot of the conveyer G and allowing the passage of the rivet-shanks into the ,1 :0- receiver.

In line with and directly beneath the dis- It will be 80 I charge of the conveyer G, I provide the shoulders H on either side of the cut-out a, which shoulders are pivoted at h on the interior of the receiver, and are provided with the angular projection H, extending upwardly therefrom. The lower ends of the springs I bear against the projections II of the shoulders H and constantly force the said shoulders against a stop h of the receiver, retaining the shoulders in their normal horizontal position in position to engage the head of the rivet when discharged from the eonveyer G. The upper end of the springs I are secured by the screw or clamp 11 to the interior wall of a cavity formed in the rivet-receiver frame.

When a rivet is fed down the conveyer G, the shank thereof enters the cut-out a, and the head thereof is engaged with the shoulders II, retaining the rivet-shank downward in the receiver in position to be discharged therefrom. Immediately upon the feeding of the rivet into the desired position in the receiver the plunger D is actuated downward to insert the same, whereupon the rivet-head forces the shoulders II downward, and the projections II rock the springs I inward. To allow of the ready disengagement of the shoulders II from the rivet-head, I preferably form the top thereof with the bevel 7L2. Directly beneath the shoulders II is the guideway a of" sufficient size to allow the head of the rivet to be easily forced therethrough by the plunger after it is disengaged from the yielding shoulders, and at the discharge of the rivet-receiver I provide the jaws or shoulders which catch the the rivets head and again arrest its progress. Upon the abutment of the rivet-head with the jaws or shoulders a of the receiver-discharge the receiver is forced downward upon the rod F, approximating the rivet to the article to be riveted, and the jaws a are so formed as to closely press the rivet-shank during this movement of the receiver.

Extending upwardly from the dischargeopening a of the receiver is the slot or slit a, dividing the receiver into two halves adapted to be sprung apart when the rivet is forced through said discharge. The rivet-shank is preferably of suflicient size to slightly spring apart the spring-halves a of the receiver, in order that the rivet may be firmly grasped by said jaws during the movement of the receiver, and the shoulders a are preferably beveled, so that after the approximation of the rivet to the article to be riveted the rivet may be readily discharged from the receiver, springing apart the jaws u When the rivet has been inserted and the plunger withdrawn, the receiver, which is made of spring metal, readily springs back to its normal posit-ion, and the springs H retract the jaws II to their normal position. After the discharge of the rivet from the jaws a the receiver is retracted to its normal position by means of a spring I, or other means secured thereto.

In Figs. 1, 2, and 4 the yielding jaws II proj ect on one side to the outside of the receiver, and the same is cut away at a to allow of the swing thereof; bntin Figs. 3 and 5 the jaws swing within a recess a? in the upper part of the guideway (1.

The operation of my pocket is as follows: A rivet is fed by the conveyer G to the receiver A, and its head is engaged by the shoulders II. The plunger is then brought down upon the head of the rivet, forcing apart the shoulders and forcing the rivet down the guideway a The rivet is forced downward to the desired position-and the spring-halves thereof are forced apart, allowing the discharge ofthe rivet, whereupon the parts are retracted to their normal position.

It will be understood that when articles of the same thickness are to be provided with rivets it is usually unnecessary to allow of a movement to the receiver, and in such cases the shoulders of may be dispensed with and the rivet forced directly through the guideway without springing apart the receiver; also, other changes may be made in the detail construction and arrangement of the receiver without departing from the spirit of my invention, which is the production of shoulders for engaging the rivet-head pro vided on the interior of the receiver and yielding downward to allow the passage of the same.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination of a rivet receiver frame, a guideway in said frame for the rivets, a chamber above said guideway, holders H, pivoted within said frame and having their adjacent extremities adapted to engage the rivet, and springs I, secured at one extremity within said receiver-frame and bearing at their opposite extremity upon the other extremity of said holder, substantially as and for the purpose specified.

2. The combination of a rivetreceiver frame having separable sections at its lower part, jaws a, provided upon the separable sections, a guideway for the rivets above said jaws, a chamber above said guideway, holders H, mounted in said chamber and pivoted to the receiver-frame, and having their adj aeent extremities adapted to engage the rivet, and

springs I, secured at one extremity within said receiver-frame and bearing at their opposite extremity against said holders, substantially as set forth.

In testimony whereof I have hereunto signed my name, in the presence of two attesting witnesses, at Syracuse, in the county of Onondaga, in the State of New York, this 25th day of February, 1889.
