To all Loli/0m it may concern Be it known that I, JAMES W. Cocinas, a citizen oi the United States, and resident ot' Philadelphia, county of Philadelphia, and

State of Pennsylvania. have invented an Improvement in Rivet-Setting-Machines, of which the following description, in connection with the accompanying drawings, is a specilication, like letters on the` drawings representing like parts. v

The invention to be hereinafter described relates to rivet setting machines, and more particularly to that type of such machines tor riveting hand bags, suit cases, and the like.

In machines of this general character, the work to be riveted is sustained by a rigid work support or post, while the rivet setting force is applied by a plunger toward the work support' or post to cause the rivet to V first pass through the work and then be set.

The character of the rivet setting force is such that the work' support or post must be rigidly held to withstand the constantlyrecurring` blows to which it is subjected, and to this end ithas heretofore been proposed to connect the' work support or post directly with the machine frame by bolts or other securing"means, or by casting a. portion ot the work support directly with the machine frame or standard. The shorter the work support or post, the more effectually will it withstand the rivet setting blows with a constant increase in the life of the machine. Certain kinds oi' work, however, require a longl work supporting post or spindle, and this is particularly so in riveting the loottoms; corners, etc., of deep hand-baga'and the like. Other-'kinds oit work do not necessitate the use of such along work support- ,ing post or spindle, as in riveting ordinary suitcases, or shallow handbags,andwhere this work is to be` done advantage has heretotorelbeen taken' ofthe vfact that a work supporting postor spindle of' less length inight be employed, anda second machine having such shorter or medium length post or spindle has been provided. In some other classes of work, such as securing the hinges, locks, etc., to hand bags and suit cases, only a very short work supporting post or spindle is necessary, and since the life of the machine isto an extent dependent upon the length of the work-supporting post Specification-ot' Letters Patent.

or'spindle and its consequent' rigidity and ability to standup under the riveting blows, a third machine has generally been provided with a short post or spindle.- In the factory equipment for setting rivets, thereiore, three machines have usually been provided, each with a work-supporting post or spindle of appropriate length for the special work to be done by that machine.

Une oi the purposes of the present invention is to provide a machine of the general `character mentioned. with a plurality 01":

work-supporting posts or spindles of appropriate length required for the work of setting rivets ,in hand-bags, trunks, suit aises, and the like, and so combine such plurality of posts or spindles in a single machine that any one of them may be'placed in operative position relative t0 the rivetsetting mechanism.

Another important feature of the present invention consists in associating the various spindles or posts on a sleeve, the character and length `of which are such that each spindle or post may be as rigidly supported for the actionjof the rivet setting mechanism as it' secured or bolted to the machine frame itself.

Still another feature of the invention consists-iii securing each of the several posts or spindles ot varying length as required by the work to a single sleeve having extended bearings on the machine column and capable of rotary movement thereon to bring any one of the posts or spindles into operative position according to the character of work tobe done.

Other features ofthe invention will liereina'fter be described in connection with the accompanying drawings, showing a good practical embodiment of the invention in its entirety.

In the drawings: Figure 1 is a side-elevation of a. rivet settinginachine, some of the parts being broken away,- ernbodying the present invention; Fig; 2 is a front elevation of the machine shown-in Fig. 1; Fig. 3 is a section on line 3-3, Fig'. 1; and Fig. i is a sectional detail showing aportion of the rivet setting mechanism.

The machine frame may be 0f any usual or desired forni appropriate for the hereinafter-described purposes, and as shown, comprises a base portion 1 from which rises the machine standard 2 surmounted by the goose-neck 3 for supporting the rivet setting mechanism. The front portion of the goose- 'curing means, the block 5 may be readily removed from the machine frame and with it the rivet setting mechanism. This is often desirable for purposes, of repair, or change in the operative conditionaof parts or for the-substitution of different fr-ms of rivet setting head.

from the chute 7 which communicates with a suitable rotating member 8 to which the rivets may be supplied through the delivering trough 9. The shaft 10 carries within thehopper S, suitable rotating means for agitating the rivets, but as these form no essential part of the present invention, de-

scription thereof is unnecessary. Secured to the shaft 10 is a ratchet wheel 11 adapted to be actuated for rotating the agitating means within the hopper by the pawl 12 mountedv on the arm 13 which isitself pivotally secured by a detachable pin 14 to the mainoperating arm 15 of the rivet setting mechanism. The arm 13 is preferably slotted,` as

at 16, to embrace the shaft 10 and be guided thereby. Mounted for reciprocating movement in the block 5 is the rivet setting plunger 17 which is connected at 18 to the stirrup or link 19 secured to the end ofthe operating arm 15, substantially as indicated in Figs. l and 4. The operating arml is pivotally mounted on brackets rising from the goose-neck 3, as at 20, the construction being such that upon movement of the operating arm 15 through the means hereinafter to be described, the rivet setting plunger 17 may he reciprocated in the block and the agitating means in the hopper 8 may be suitably rotated.

As the rivets are fed downward in the chute 7, they are to be presented singly to the rivet holder which, in the present form of the invention, comprises the head 21, l Fig. 2, carried by the arm 22 mounted for reciprocating movement in the block 5 and normally held in raised position by a spring 23. The arm 22 has connected therewith an adjusting screw 24: whereby to limit the delivered to the holder 21 one at a time, the

chute 7 is provided with a cut-ofi' or slide 25, Fig. 4, which is mounted for movement 'slide in position to transversely ofthe chute and is provided i with an opening, as' usual for the passa of a rivet `therethrough from a position a ve to a position below the said cut-oil or slide. Thefcut-of or slide 25 is normally under the influence-of the s rin 26 which` acts upon the slide or cut-o to old it in the position indicated in. Fig. 4, whereb it prevents movement of rivets downwar in the chute. Pivotedto the block 5 at 27 is a slide actuator 28, the upper end 29 of which is in the path of a arm 15. e actuator 28 is provided with a in 30A mounted on the actuating' leaf spring 31, the end of which normally l rests against the end of the slide or cut-off 25 opposite the spring 26, the construction being such that upon operative movement 'The block 5 has extending upward therebeing imparted to the arm 15 as hereinbefore explained, the yactuator 28 will be moved upon its pivot 27 and the leaf spring 31 thereof wlllcause a yielding movement of the slide 25 to bring the opening of the rmit a rivet in the chute to pass to the ower partthereof, as usual.

From the construction thus far described,

it will be noted that by the simple removal of the two screws 6 or other holding means, the block 5 together with its contained or supported rivet setting mechanism may be entirely removed from .th'e machine after lhaving also removed the removable pin 14 which holds the ratchet operating arm to the actuating arm 15. It will also be noted that the slide is moved in opposite directions by springs 26 and 31, the'spring 31 being stiffer or more energetic than the spring 26 so that as the slide 25 moves to permit a rivet to pass down the chute to the holder, its actuation is of a yielding Anature and likewise on its return so that in case of any obstruction, the slide or pther parts may not be injured or broken.

As hereinbefore pointed out, different kinds of ivork require different kinds of work supporting posts or spindles, and it is a recognized fact in the art that the spindles must be retained with suiiicient rigidity to Ywithstand the repeated blows delivered thereto by the rivet setting mechanism. This rigidity is mostfillly `secured by a short work sup rting post or. spindle on account of the siidrter leverage, and the art has` recognized this fact by the employ-- ment of such short posts or spind es where the character of the work to he one permitted. The rigidity of the work-supporting spindle is also dependent upon its rigid connection with the supporting part which,

in the ordinary riveting machine, lspart of the machine frame.

In order that the rivet setting may be carried into clfect upoir the bottom portion of deep hand bags, trunks, and the like, a

long supporting post or spindle is required;
