UNTTED STATES `PATENT OLIVER SIEGLER, OTTO SIEGLER, AND FERDINAND SIEG-LER, OF BELLEVILLE, ILLINOIS.

ADJUSTABLE RIVETING-STAKE.

To all whom 'it may concern:

Be it known that we, OLIVER SIEGLER, OTTO SIEGLER, and FERDINAND STEGLER, citizens of the United States, and residents of Belleville, Illinois, have invented certain new and useful Improvements in Adjustable Riveting-Stakes, of which the following is a specification.

This invention relates to improvements in an adjustable riveting stake and consists in the novel arrangement, construction and combination of parts as will be fully hereinafter described and claimed.

The object of our invention is to construct a machine with a plurality of riveting dollies adjustably mounted on a support for retaining rivets in alinement and so adjusted as to correspond with the rivet openings in the material to be riveted, each dolly being provided with a rivet holder whereby the rivet is held in position while the article to be riveted is placed in position.

A further object of our invention is to provide a mechanism in which the rivets are inserted and by the manipulation of a handle the rivets are placed in position and in alinement so that the article to be riveted may be placed on the machine, the holes in the article corresponding with the position of the rivets so that the operator may readily and easily rivet the article without the necessity of using a helper for supporting one end of the rivet while the hammer is being brought in contact with the rivet.

provided with a projecting plate 12, its eenter being provided with an aperture through which a king bolt 13 is inserted. On the plate 12 is mounted a table 14, its center being provided with an aperture and recess to accommodate the insertion of the head of the king bolt, this construction permitting the table and the mechanism carried thereby to be turned to accommodate the position of the workman.

On the table 14 is securely fastened a dolly-bar 15, its under surface on each side of the table provided with a T shaped groove 1G which is for the purpose of accommodating the insertion of a bolt 17. By the bolt 17, the guide frame 1S is held in position, one of said frames being located on each side of the table and by the manipulation of the bolts, the supporting frames can be adjusted to accommodate the width of the article to be riveted. The dolly bar 15 is rigidly retained in position upon the table 14 by bolting the same thereon or the same may be formed integral with said table if found desirable. The upper surface of the dolly bar is provided with a curvilinear groove 19. In this groove rests the periph` ery of each dolly 20, the connection at this point being such as to permit the same to contact yet allow the dolly to be moved when desired to accommodate the use of the different styles of rivets. As we use rivets with different styled heads such as cone, flat or round depending on the material or article to be riveted and when such styled rivets are to be used, the dollies must be adjusted to bring the proper recesses in position to accommodate such rivet.

On each end of the dolly bar 15 is attached a support 21 in which is mounted a shaft 22, said shaft extending the entire length of the machine and passing through apertures formed in the center of each dolly, thus retaining said dollies in alinement and on said shaft said dollies may be adjusted laterally to accommodate the spacing of the rivets. On said shaft 22 are mounted rivet holders 23, which consist of a yoke, the arms 2st of said yoke located on each side of the dolly, the free ends of said arms provided with recesses 25 in which is firmly secured a bar 26, this bar extending the entire length of the machine, connecting each rivet holder and by this bar the entire series of rivet holders can be simultaneously operated.

In the rivet holder is pivotally mounted a rivet prong 27 which is made preferably of spring material, its curved end provided with a slot 28 through which vthe shank of the rivet projects; the teeth 29 contacting with the inner surface of the rivet head thereby holding said rivet in position. VThe rivet 'prong' is attached lto a plate 30 which is provide with a pair of perforated ears 31 and through said ears and through holes 32 formed in the rivet holder is placed a pin 33 by which the rivet prong is pivotally retained in position, the 'teeth 29 of said rivet prongs being held incontact with the peripheries of the dollies by an expansive spring 34. On one end "of the shaft v-22 is mounted `a handle'35 on which is carried a sliding `tooth 36 designed to come in contact with the recess 37 vformed in the projection 38 of the support 21. The sliding 'tooth 36 is operated by the spring actuated handle'39 and byfmeans of the tooth 36 the entire series of rivet holders can be retained in an elevated position, as shown in Fig. 4, when the handle is operated and the tooth con` tacting with the lowest 'recess in the projection 38. On the front surface of the dollybar 'is-placed a plurality of adjusting blocks 40 corresponding in Ynumber with the dollies, the said blocks provided with recesses 41 into "which the dolly projects. The prongs 42 which project by the forming of the recess,'conta"ct with the sides of the dolly, retaining the same in posit-ion and by said prongs the dolly together with the rivet holder can be'adjusted on the shaft 22.

The'adjusting-blocks 40 are'held in locked positionlafter adjusting by means of the-bolt 43; the head retained inea T shaped groove 44 formed in the dolly-bar; the threaded end of said bolt having a nut 45 which is manipulated by the operator when desiring to adjust and work the adjusting blocks in position. The adjusting block is also provided withfa dolly locking pin 46, said pin being spring actuated and provided with a head 47 the inner surface ofthe head provided with a lug 48 which is designed to come in contact with the projection 49 formed on the face of the adjusting block, holdingthe pin out of contact with the dolly when it is desired to rotate the'dolly when setting the same to accommodate the required style of rivet.

The peripheries of the several dollies are provided with recesses, two of said recesses shaped to accommodate the insertion of the end of the pin 46; a recess 50 formed to accommodate a cone-head rivet, the surface being inclined so as to permit the cone-head rivets to be conveyed into the recess 51 in which the rivets are held in perpendicular position in alinement so that the article to beriveted can be readily placed in`position over the rivet shan'ks.

The-recess 52`is arranged-to accommodate a flat-head rivet, its surface tapering to a flat-tened surface, 53 formed on the dolly on which is set the head of said rivet and also held vin position when the dolly has been Vproperly adjusted so that the flat surface 53 is brought at the top of the machine. p

The guide frames 18 have a pair of lhorizontal projecting prongs 54, said prongs through which 'projects a pin 58 and on said pin 'between the Vvears is a coil spring 59 which is so arranged as to keep `the upper end of said pin in raised position, yet the spring beingo'fsuch tension as'to Ipermit the pin 'to lower when the article to be riveted vcomes in contact therewith. The purpose of said pin is to permit the edge of the article to be riveted to contact with the side thereof which when vregulated will act as a `guide for the article to be riveted, permitting -the holes in the material to correspond with the line of rivets supported on the-machine, and the reason kof the pins lowering when 'contacted by the article is that lin the event the article is of -suoh length that `theoutermost guide is necessary, the inner one will not interfere as the weight of the 'article will depress the pins. The bars 55 'are held in horizontal position by the spring `actuated pin (30 fitting into the bore 61 formed in the ba'r, and'said pin 60 is manipulated by means ofthe knob 62. This pin is held in position in the boss`63 located on one of the prongs ofthe bifurcation, and whenonly one set of bars are vused the other pair are permitted to hang in vertical position out of the way of the operator.

The guide blocks 56 are `'held in their Shorizontally adjusted positions upon the bars 55 Y* bymeans of `rthe thumb-screw 64 carried by the block. See F ig. 3.

The operation of'our `invention is as follows: The machine as shown in the drawings, is set `for handling cone-head rivets. The rivets are placed in the grooves 50 between lthe teeth 29 of the rivet prong and when the entire series of rivet holders are provided vwith rivets, the operator manipulates the handle'35 raisingthe rivet holders in a position `as'shown-by solidlinesin fFig. 4and by dotted lines in Fig-5. The rivets areconveyed forward until the heads lodge within the 'recesses 51. The article to be riveted is then placed on the guide frame, the edge contacting'with one ofthe guides as `set for the purpose. rllhe punches or openings inthe material to beriveted being in'alinement with the row of'rivets, the article is then vplacedover'the rivet Shanks permitting thefshanks to project through the openings ;the operator-then *manipulates the handle 35 bringing the same in horizontal plane as shown in Fig. 5, lowering the rivet holders, releasing the prongs from the rivet, the rivets being held in place upon the dolly by the weight of the article and the rivets are then flattened by the use of a hammer and when completed the article is removed from the guide frames. When it is desired to use at-head rivets, the operator manipulates the head 47 withdrawing the pin 46, then revolves the dolly to its proper position bringing the flat surface 53 on the top. The pin 46 is then released and its end permitted to lodge within the recess formed in the dolly locking same. When it is desired t-o adjust the dolly horizontally on the shaft 22, the thumb-nut 45 is manipulated and the entire mechanism is shifted on the shaft so as to regulate the spacing of the rivets and when adjusted the screw is tightened to retain the mechanism in rigid position.

This construct-ion of mechanism has been especially designed for riveting stove and range bodies, and by its use the rivet heads are kept in perfect condition and unbattered. It disposes with the use of a helper to hold the rivet-head while the shank is being flattened. By the movement or rotation of the individual dollies, we can assort the rivets in the riveting alinement, bringing a mixture of flat or cone head rivets.
