WILLIAM DUNN, OF PHILADELPHIA, PA., ASSIGNOR OF TWO-THIRDS TO DANIEL B. RUFFNER AND GIDEON S. BOLTON, BOTH OF SAME PLACE.
MACHINE FOR MAKING NUT-FASTENERS.
SPECIFICATION forming part of Letters Patent No. 356,279, dated January 18, 1857 Application filed July 31, 1886. Serial No. 209,640. (No model.)
.To all whom it may concern.-
Beit known that I, WILLIAM DUNN, a citi zen of the U nited States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Machines for Making N ut-Fasteners, which improvement is fully set forth in the following specification and accompanying drawings, in which- Figure 1 represents a top or plan view of a machine for making nut-fasteners embodying my invention. Fig. 2 represents a side elevation thereof. Fig. 3 represents a horizontal section of a detached portion. Fig. 4 repre sents a horizontal section of a detached portion. Fig. 5 represents a partial side elevation and partial vertical section of a detached portion.
Similar letters of reference indicate corresponding parts in'the several figures.
My invention consists of a machine for making nut-fasteners which are of serpentine form with eyes at the ends thereof, said machine embodying means, first, for converting a blank or piece of metal into serpentine form, and, next, producing the eyes on the end of the same.
Referring to the drawings, A represents the frame of the machine, and B represents a bed which is supported on said frame. Rising from the bed and stationary thereon are two studs, 0, which extend vertically and are separated a suffici-ent distance to permit the passage between them-of a blank or bar or piece of iron, as most clearly shown in'Fig. 3.
In the bed are segmental slots D, and below the same is a lever, E, which is pivoted to the frame and carries two pins or studs, F, which project upwardly through the slotsD and are parallel with the studs 0, and are adj ustably connected with the lever in a Vertical direction, so that when their upper ends become worn or fractured they may be cut off and fresh parts presented in lieu thereof.
G represents rotary shafts or spindles, which are fitted in bosses or bearings H, the latter being bolted or otherwise secured to the bed A, said shafts being of crank form and carrying on their lower limbs fingers J, which are so disposed that when the shafts G arerotated said fingers are brought into contact with ends of the blank or piece of metal which is introduced between the studs 0. I
The fingers J are adj ustabl y connected with the limbs of the shafts G, so as to project from said limbs to greater or less extent, and the limbs of the shafts are adjustably connected together by means ofbolts or screws K, whereby the throw of the lower limb of the crank-shaft, and consequently the fingers .l, may be adj usted.
Connected with the shafts G are levers L, whereby said shafts may be operated, and to said levers are attached laterally-projecting toes M, which areadapted to abut against stop-pieces N, the latter being secured to supports P, which are bolted or otherwise fastened to the bed 13, said pieces N being on opposite sides of the studs 0 and serving to limit the motions of the levers L.
Qrepresents a gage,which is adjustably connected with the bedB or adjacent portion of the frame A, whereby the blank may be set true in position between the studs 0. I
The operation is as follows: The lever E is moved so as to occupy a posit-ion at a right angle to that shown in Fig. 1, and the blank is then placed on the bed between the studs 0, it being noticed that the studs F are on opposite sides of the blank between the center and ends thereof. (See Fig. 3.) The lever E is now returned to its first position, and as the studs F bear against the blank the central portion of the latter is beutin opposite directions around the studs 0, as shown' by the dotted lines, Fig. 3, thus producing the body of the nut-fastener. The lever E is now secured by a'eatch or fastening, B, so as to remain immovable d nring the subsequent operation, said catch being properly attached to the frame A. The levers L are now moved, and as the fingers J bear against the ends of the blank, the latter are bent around the studs F, thus forming the eyes on the ends of the nut-fastener. The levers L are returned to their first position and the nut-fastener removed from the studs 0 F, after which the lever E is released and again advanced to a right-angular position. Another blank is placed between the studs 0 and then subjected to the operations described in the previous case. The collars F, which connect the studs F with the lever B, are laterally adjustable by means of bolts F", whereby said studs may be set nearer to or farther from each other, and thus adjusted in relation to the studs 0.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is I 1. In a machine for making nut-fasteners, a bed-plate having two studs thereon, in combination with a pivoted lever carrying two studs which are adapted by the movement of said lever to partially rotate around the studs on the bed-plate, all substantially as and for the purpose set forth.
2. In a machine for making nut-fasteners, the stud F, secured to a lever,said lever-having means for securing the same in fixed position, the shaft G, having a suitable bearing secured to the frame of the machine and provided with fingers J, and lever L, all combined substantially as and for the purpose set forth.
3. The studs C 0, between which a blank may be fitted, the movable studs F F, which bend the blank around the said studs 0 0, levers Eand L, and the fingers J .I, which move around the second-named studs and thereby form "eyes on the ends of the blank, said parts being combined and operated as set forth.
4. The bed B, with slot-s D, and provided with studs 0 O, the pivoted lever E, carrying studs F F, projecting through said slots D, and the pivoted levers L, carrying fingers J, which rotate around the studs F, all combined and operated substantially as described.
5. The stud F, in combination with the crank-shaft G, having lever L, finger J, and
toes M, the stops N, and supports P, all substan'tially as described.
'6. The stud F, in combination with finger J, attached to the crank-shaft G, and lever L, whereby said fingers are partially rotated around said stud, all substantially as and for the purpose set forth.
7. Thestuds FF, adjnstably connected with their supporting-lever, the slotted bed B, with studs 0 0 attached thereto, all combined and operated substantially as described.
8. In a machine for making nut-fasteners, the bed-plate B, having slots D, and provided with studs 0 G, in combination with frame A, having the lever B, carrying studs F F, all substantially as described.
9. In a machine for making nut-fasteners, the frame A, the lever E, with studs F F, the crank G, with fingers J, and lever L, all combined substantially as and for the purpose set forth.
10. In a machine for making nut-fasteners, the frame A, with pivoted lever E, having studs F F, the slotted bed-plate B, with studs 0 C, the catch It, and adjustable gage Q, all combined substantially as described.
11. In a machine for making nut-fasteners, the bed-plate B, having bosses H, the crankshaft G, having fingers J and lever L, and the lever E, having studs FF, adj ustablc therein, all combined substantially as and for the purpose set forth.
