- nrvnrme MACHINE Application filed September 19, 1329. Serial No. 393,634.

My invention relates to riveting machines, and especially to constructions or arrangements of the supporting means for the riveting head (or riveting mechanism proper), and cooperative arrangement of the anvil and anvil support, to provide a rearwardly or laterally extending space or recess to receive relatively long articles which must extend rearwardly or laterally while the rivets, eyelets, or other fasteners, are set in forward portions of the articles.

One example of such articles requiring a rearward extending space or recess in the riveting-head supporting means, is garment bags, in which the rivets are to be set in a margin of the open or mouth end of the bag while the bag itself is disposed generally horizontally, and projects rearward, or away from the operator and toward the rear of the machine. quite a long distance. The machine is also of course available for many other classes of articles requiring a large rearward or lateral clearance in the head supporting means. 7

In preferred forms, such clearance space is provided by a separate, generally U-shaped supporting member, secured between the main standard, or supporting column, and the riveting head, and extending in a desired rearward, angular, or lateral direction, in accordance with the form or dimensions of the articles to be riveted.

The invention furtherprovides a support or magazine for a stack of articles, (such for example as garment bags) which may be successively moved from the magazine tO I1V6ting position.

The characteristics and advantages of the invention are further sufficiently explained in connection with the following detail description of the accompanying drawings, which show one representative embodiment. After considering this example, skilled persons will understand that many variations may be made without departing from the principles disclosed, and I contemplate the employment of any structures that are properly within the scopeof the appended claims.

In the drawings:

Fig. l is a side elevation of a machine embodying the invention in one form.v

Fig. 2 is a front elevation.

Fig. 3 is a side elevation of a modified structure or arrangement.

Fig. 4: is a similar view of another modification.

Fig; .5. shows another modification.

Fig. 6 shows still another modified form.

In Figs. 1 and 2, 10 is a standard riveting head, or support for the rivet setting mechanism proper, 11. The head or support 10 comprises an upright portion 12 and a horizontal arm 13, at the end of which is the rivet setter 14: to cooperate with an anvil 15. Ordinarily, the head 10 is secured to a supporting standard or column such as 16 by bolting the base 17 of the vertical member 12 directly to the top of the column. This evidently provides very little lateral or rearward clearance, or space in a direction away from the operator, who is stationed in front of the machine (at the right in Fig. 1), and toward the machine; and it is therefore practically impossible to operate on relatively long articles which must extend in the stated directions while rivets are set in forward margins thereof, located between the setter 14 and anvil 15. To provide the rearward or other clearance necessary for work of the character indicated, in the specificform of the device shown in Figs. 1 and 2, I interpose between the head .10 and column 16 a generally U- shaped head-supporting member 18, comprising an upper arm 19, a lower arm 20 and a connecting portion, or U-bend 21 connecting the arms. The base of the upright member 12 of the head is connected to the front end of the upper arm 19 by bolts or screws 22, and an intermediate portion of the lower arm 20 is connected to the top of the column bybolts 0r screws 23; The space or bight 24 between arms 19 and 20 provides the necessary ample rearward clearance for articles of the character above mentioned. In the structure of Figs. 1 and 2, an integral portion 25 of arm 20 extends forward and upward, and the anvil 15 is secured non-adjustably or adjust ably in the forward end of this arm inproper position below the rivet setter 14, the position of which is determined by the standard.- ized dimensions of the head 10. Deep garment bags or other articles which must extend a long way rearward or away from the operator, are pushed into the space between the rivet setter and anvil and into the space or bight 24c, and may be moved laterally as rivets are set in their forward marginal portions. 7

While the U-piece 18 is here shown as extending rearward, it may extend angularly or laterally, in a generally horizontal direction, to accommodate wide work-pieces of various characteristics. V

In the preferred forms, as shown in Figs. 1 and 2, and other figures later referred to, the generally U-shaped supporting structure 18 is separate from the column 16 and the head 10 and may therefore be inserted be tween any column of suitable height and any ordinary or standard head such as 10; and when the anvil supporting member such as 25 is, as shown in Fig. 1, properly directed or arranged with reference to the dimensions of the head, the anvil is thereupon properly positionedin relation to the rivet setter 14.

The separate U-piece provides great facility in assembling complete machines, since it is only necessary to place and secure it between the column and the riveting head, in a desired position, to adapt the machine for any of a. variety of operations, or work pieces of varying shapes or dimensions.

If desired, the arms 20 and 19 and U- bend 21, or their equivalents, may be integral with the column and upright 12 of the head 10 and the anvil supporting member may be also integral, or separate piece and attached to the column in any convenient way.

Fig. 3 shows a modification in which the anvil supporting member or arm 25 extends forward and then upward at 26 and its end portion 27 is turned horizontally reversely or backward toward head 10, thus providing a space at 28 extending forward below the anvil 29 which is secured in the end of the horizontal member27. This allows for the convenient location of one portion of a workpiece, such for example as the margin of one side of the mouth of a garment bag, in the space 28, without bending or crumpling, while the margin of the upper portion of the mouth is placed between the rivet setter 14 and the anvil 29 for convenient setting of rivets in that margin.

This arrangement as well as others also provides a convenient support or magazine to receive, for example, a stack of garment bags or other articles located in the space be r tween support arms 19 and 20. The speed of operations is increased by placing such a stack of articles in the magazine and draw ing forward the uppermost articles successively for the riveting operation. When the articles are wide as well as long (or deep) their laterally extending portions may be supported by tables placed at either side of the machine as viewed in Fig. 2.

Fig. 4 shows another modification, in which the arms 19 and 20 of the intermediate supporting structure 18 are sloped rearwardly downward, thus better providing for the proper retention in the magazine of a stack of articles, which will naturally tend by gravity to remain in proper position in the magazine, resting against the U-bend 21, while the uppermost articles are successlvely moved forward for the riveting operation.

The anvil 15 is in this example carried by an diate supporting structure such as shown in Fig. 1 has an integral forward extension 35, and the anvil 15 is carried by a separate upright support 36 bolted at 37 to the forward end of the extension 35. The anvil support is curved forward and then rearward, providing a bight or space at 38 for purposes generally similar to those of the space 28 in Fig. 3.

In Fig. 6, the intermediate supporting structure 18 is of simple U-form and the anvil supporting means comprises a forwardly extending horizontal member 40 and an upright member 43. The horizontal member 40 is bolted to the column 16 at 42 and the stem 43 of the upright member is bolted to the forward end of arm 40 at 44:. The stem 1-3 of the upright member has at its upper end a U-fo'rmation 45, the bight 46 of which is directed rearward to provide a space for certain portions of articles while other portions thereof are riveted, as, for example, in Figs. 3 and 5. The anvil 15 is secured in the upper end of the U-formation.

From the examples given, it is evident that the general objects of the invention may be attainedby various specific structures and that the supporting structures, as above explained, may be in two or more parts, to provide ample rearward or lateral clearance or article receiving space, which is a principal feature of the invention.
