FREDERICK J. GREENE, OF RACINE, WISCONSIN.

AUTOMATIC RIVETING-MACHINE.

Application filed June 30,

T 0 all whom it may concern: 7

Be it known that I, FREDERICK J. GREENE, a citizen of the United States, and resident of Racine, in the county of Racine and State of Wisconsin, have invented new and useful Improvements in Automatic Riveting- Machines, of which the following is a description, reference being had to the accompanying drawings, which are apart of this specification.

This invention relates to improvements in automatic riveting machines more particularly adapted for riveting edge strips of angular form in cross section to panels or side members in forming trunks and -simi lar boxlike receptacles.

In the present manufacture of trunkscthe side or panel portions are nailed together along their adjacent edges or to an edge member by hand. This construction requires considerable time and is not as accurate nor as strong as machine work in which the parts are riveted together.

It is-one of the objects of the present invention to overcome the before mentioned objectionable features and to provide an automatic riveting machine with means for holding a panel whileangular edge strip-s are riveted thereto, and also for holding the panels while other panels are being riveted to the edge strips.

A further object of the invention is to provide an automatic riveting machine in which means are provided for automatically and intermittently moving the panel or partly assembled trunk or the like certain predetermined distances with relation to the riveting portion of the machine to receive rivets in lines and spaced distancesapart.

A further object of the invention is to pro vide an automatic riveting machine in which the panel or trunk part may be intermittently moved in lines backwardly or forwardly or at right angles thereto to permit :the riveting of all edge portions of the trunk.

'A further object of the invention is to provide an automatic riveting machine which is of simple construction, is strong and durable and is well adapted for the purpose described.

With the above and other objects in View the invention consists of the improved automatic riveting machine and its parts :and combinations as set forth inthe claims and all equivalents thereof.

the same reference characters indicate the same parts in all of the views Figure 1 is a perspective viewgof a riveting machine embodying the improvements; Fig. 2 is a front detail view ona larger scale of the mechanism for feeding the trunk parts laterally across the front portion of to the feeding mechanism; a F 1g. 5 1s a vertical sectional view thereof;

Fig. 6 is a perspective view ofthe brackets and ,the slidable member for holding the.

trunk panels while riveting the angular edge strip thereto; and

Fig. 7 is a sectional detailview of an edge portion of a trunk.

Referringto the drawings the'numeral 8 indicates -a riveting machine which comprises a base portion 9, an upstanding column 10, an outwardly and .upwardly extending arm 11, an outwardlyzand downwardly extending coacting hammer-arm 12, a riveting hammer 13 and a rivet supply mechanism 14. The movable parts are actuated by the driving mechanism'15 mounted on and extending transversely of the upper portion of the machine. The portion of the machine thus far described is of ordinary slidable arm is formed with a horizontally extending T-shaped groove in cross section 19 for adjustably receivin the heads of adjusting bolts 20 of the guide arm 18 to permit adiustment of said guide arm on the bar. Mounted on the lower side portions of the guide armis a transversely extending slidablemenrber 21 carrying a longitudinally extending rod 22 and forwardly from this rod project supporting arms 23. The supporting arms are of angular form in cross section and are adapted to support the lower edge portions of the trunk, being riveted together.

A clutch wheel 24 connected to the driving mechanism 15 carries a loosely mounted disk 25 provided with an outwardly projecting tubular wrist pin 26. The wrist pin is provided with a spring pressed bolt 27 which is adapted to enter one or the other of the two bolt openings 28 formed diametrically opposite each other in the clutch wheel 24 to permit the changing of the time of movement of the rivet hammer with relation to the direction of travel of the supports 23 as it is obvious that when the bolt is positioned in the loweropening 28 the hammer 1.2 will move downwardlywhen the feed of the trunk is in the opposite direction. A connecting rod 29 having its upper end portion pivotally connected to the wrist pin 26 is provided with a manually operable lever 30 which is fulcrumed on the rod and is connected at one end to the spring pressed bolt 27 to permit the easy withdrawal of the bolt from the bolt openings in changing from one opening to the other to adjust relative movements of the parts. The lower end portion of the connecting rod is adjustablyconnected to an arm 31 mounted on the rear end of a rock shaft 32, and the rock shaft is journaled on the side portion of the upstanding column 10. A vertically extending arm 33 mounted on the front end portion of the rock shaft 32 is connected to one end of a connecting rod 34. The opposite end of the connecting rod is pivoted to a slidable block 35 which carrlesa spring pressed dog 36 having its lower end of angular formation to freely snap over the teeth of the rack bar 37 during the retrieving stroke to the left of the slidable block. During the working stroke to the right the dog will positively engage the teeth and move the said rack bar a'predetermined distance. The dog 36 extends upwardly through the block and carries fast thereon a collar 37 which is provided with, a downwardly extending pin 37 This pin is adapted to removably enter either one of two openings 39 formed in the slidable block to permit turning the dog 36 to reverse the direction of the working stroke thereof. The spring of the dog will hold the parts in adjusted position and by lifting and turning the dog a one quarter turn the pin 37' will rest on the upper surface of the slidable block and hold the dog out of engagement with the rack bar. The upper end portion of the spring pressed dog is provided with a knob or handle 36 for convenience in lifting or turning the dog.

The rack bar 37 is adjustably mounted on the slidable bar by a bolt and slotted connection 38 and an adjusting screw 39 to adjust the position of the trunk with relation to the riveting portion of the machine.

In riveting the angled edge parts 40 to the trunk panels or sides 41 before said panels are joined together, supporting brackets 42 are adjustably bolted to the slidable bar 17 in spaced relation as shown in Fig. 6 for holding said panels and the angled edge parts in proper position with relation to the riveting portion of the ma chine.

The transversely extending slidable member 21 is also provided with a rack bar 43 for intermittently moving the supporting arms 23 toward or away from the upstanding column 10. The rack bar and the supporting arms 23 are moved-by a spring pressed dog 43 which is carried by aslidable block 44 mounted on one side portion of the guide arm 18. The dog is similarto the dog 36 and is provided with a fixed collar 45 having a depending pin 46 which is adapted to enter either one of two openings 47 to adjust the direction of movement of the rack bar. The dog is also provided with a knob or handle 48 for adjusting the dog in the same manner before described with relation to the dog 36.

The block 44 is slidably mounted on the side portion of the arm 18 and has a link connection 48 with an upstanding arm49 slidably mounted on a transversely extending rock shaft 50 of rectangular shape in cross section. Said arm 49 is formed with a rectangular opening 49 to fit the rock shaft 50 so that it will be rocked thereby and is maintained in its position with relation to the arm 18 by bearings 51 which surround the shaft on opposite sides of the arm 49,

thus causing said arm 49 to move transversely with the arm 18. The rock shaft 50 is journaled and supported from the opposite end portions of the transversely extending guide member 16. One end of the rock shaft 50 is provided with an arm 52 fast thereon which has a vertically extending link connection 53 with one end of a bell crank lever 54 fulcrumed on the upper portion of the transversely extending guide member 16. A horizontally extending link 55 connects the other end of the bell crank lever 54 to the vertically extending arm 33 before described thus reciprocating the dog 43 from the same rock shaft 32 that reciprocates the other dog 36.

A foot pedal 56 controls the operation of the machine in the ordinary manner.

In use one of the trunk panels or sides is placed on the supporting arms 42 and the rivet willbe driven through the edge poition. of the panel and set on its tubular. end portion spread; As soon as this operation is completed the movable hammer arm will be raised and while traveling upwardly the supports with the panel and attached strip will be-moved inwardly toward the column.

36 moved into engagement with its rack..

This adjustment will cause the panel to be moved intermittently in steps across the frontof the column and the rear edge strip to be riveted to the panel. When this edge is completed the dogs are changed as before with the exception that the dog 36 is positioned to feed in theopposite direction and the bolt 27 is changed to the other opening 28 to change the relative movement of feed with respect to the travel of the supports. When thus adjusted the panelwillibe intermittently moved away from the columnlO while receiving rivets. When the edge pieces have been attached to, the panel the other panel pieces may then beeasily connected to the edge pieces in the same manner described by placing them on the brackets and supporting the panel to which the edge piece has been attached at right angles thereto. When the trunk is partly assembled the brackets 42 may be removed and the partsbe supported on the arms 23 as shown in F ig. 1. In either case the riveting operation will be the same.

From the foregoing descriptionit will be seen that the automatic riveting machine is of very simple construction and is well adapted for the purpose described.
