BUTTON-ATTACHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 517,485, dated April 3, 1894. Application led March 3, 1893. Serial No. 464,490. (No model.)

To a/ZZ whom it may concern.-

Be it known that I, FREDERICK A. RYNo, of St. Paul, Ramsey county, Minnesota, have invented certain Improvements in Button-Attaching Machines, of which the following is a specification.

My invention relates to improvements in machines designed for riveting buttons upon garments, its object being to provide a simple and inexpensive mechanism which will perform all the operations by simply working the treadle. l A

To this end my invention consists in the improved features of construction hereinafter described and claimed, reference being had to the accompanying drawings, in which- Figure 1 is a sectional side elevation of my improved machine. Fig. 2 is a front eleva- Fig. 3 is a detail front elevation of the perforator and its carrying block. Fig. 4 is a detail side elevation of the same. Fig. 5 is a detail of the treadle and its connecting rods. Fig. 6 is an inverted plan View of the oscillating button carrying plate. Fig. 7 is a sectional detail of the plunger cylinder, and Fig. 8 is a detail of the lower end of the conduit bed and the pivoted plate connected with the same.

In the drawings A represents the table or base of the machine supported upon suitable standards 2.

At or near the front of the machine is arranged the hollow cylinder or guide 3 preferably screw threaded into the table A so as to be held rmly in vertical position. In this cylinder works the plunger 4 which is pivoted to the connecting rod 5 leading to the treadle of the machine. The bed 7 having suitable rigid support upon the machine is fitted with'the button receptacles 8 and 9 and the rivet receptacle 10. Leading from the receptacles 8 and 9 are the conduits 11 and 12 which converge -and unite in the main conduit 13. Just above the point of junction a rocking gate 14, operated by suitable connections with the running parts of the machine, serves to pass the buttons 17 singly down one of the branch conduits 11 and 12 to the main conduit 13, a switch stop 15 being pivoted between the branch conduits 11 and y12 and adapted to be swung over and stop the buttons in either conduit as desired, thus permittin g the buttons to pass but from one receptacle at a time to the machine. Similarly the receptacle 10 is connected by means of a 55 conduit 16 with a slotted opening 18 in the side of the cylinder 3 and the delivery of the rivets 19 singly along the conduit is secured by means of the pivoted gate 2O connected in any suitable manner with the operating 6o mechanism, so as to permit one rivet to pass with each operation of the machine. The plate 21 is pivotally supported upon the standard 6, and has jointed connection with the bed 7, and is provided with a button conduit 22 connecting with the main conduit 13. The plate 21 is curved downward and backward,. as shown.

Pivoted upon the standard 23 is the head B, which is turned by means of the operating 7o lever 24 connected thereto by means of the link 25, the lever being operated by means of the connecting rod 26, leading to the treadle of the machine. The head B carries a hammer 27 threaded into the head so as to be ac- 75 curately adj usted. This hammer is a permanent magnet and is formed with a central b oss 28 at the end to flt to the hollow in the center of the button. The hammer stands immediately back of the lower end of the 8o plate 21, so that as the button drops down in vfront of the hammer it is drawn against the hammer and held by the magnetic attraction.

A stop 29 secured to the plate 21 adjacent to the conduit 22, and projecting over the same, serves as a stop against which the button strikes as it falls down the conduit. This stop stands normally below the center of the hammer so that the button is stopped directly in front of it. The plate 2l at the bottom of 9o the conduit is cut away at this point, and the bent fingers 30 and 31 are pivotally secured to the under surface of the plate, and project downward with their ends slightly separated from each other over the opening through the These ngers are held normally closed together -by means of a spring 32 engaging their upper ends, in such position that there is not sufficient space between their tips for a button to pass through. The tips of the roo fingers are provided with stops 33 and 34 with which the beveled spurs 36 and 37 upon the adjustable plate 35 carried by the hammer head engages, with the first forward movement of the head. The lingers are thus thrust apart sufficiently to allow a button to be drawn through between them by the magnetic attraction of thehammer. The projection 3S on the rear portion of the head to which the link 25 is attached, is also connected by means of the bent rods or wires 39 to the plate 21.

Mounted upon the pivot 40 of the head B and adjacent to the head, is a bleek or hub 41 to which is pivoted the plunger' rod 42. This red passes down through the base plate A and is provided with a spiral spring 43 engaging a stop on the lower end of the rod and the under side of the base plate. The spring thus tends to keep the rod thrust downward and the block turned backward, the limit of its movement in that direction being determined by the stop 44 fixed in the plate and engaging a projection 45 upon the under side of the block. livoted to this block and hinged to turn laterally thereon,is the bleek or head 46 carrying the bent needle or perforator 47. The head 4G is held from turning toward the head B by means of the spring 48, and is stopped from turning outward by the post 49, with which engages the anti-friction roll 50 carried by the head 46. This post is beveled on its rear and front sides as shown, se that as the head turns on the pivot the anti-friction roll rides up on the rear beveled surface 51 and thrusts the perforator over toward the cylindrical guide 3, the parts being so adjusted that its point will enter the center of the opening in the cylinder'.

Pivoted to the front of the head B is the linger 52 having alateral proj eetion 53, adapted to engage a stop 54 on the head 46, as actuated by the spring 55, which tends to thrust the linger laterally. As the head B turns forward, the head 46 is rocked until the perforator enters the cylinder 3. Thereupon the end 56 of the finger 52 strikes upon the anti friction roll 57 which is supported on a pivot post 58 in the base, by which it is thrust away from the head, thus releasing it and allowing the spring 43 upon the plunger 42 to reverse the movement of the head 46 and withdraw the perforator from the cylinder, and out of the path of the hammer in time for the latter to descend.

The operation of the machine is as follows: The garment being placed across the top of the cylinder 3 in position to receive the button, the treadle 59 is worked so as to operate the switches adjacent to the conduits, as above described, and allow a button to descend in front of the hammer, and a rivet to enter the cylinder 3. When the treadle is again operated, the initial movement turns the head B, throwing the hammer forward, the rods 39 connecting the head with the plate 21, at the same time carrying the lower end of the plate 21 outward. The plate 35 carried bythe head B engages the stops upon the fingers 30 and 31 spreading them, and allowing the button to be drawn inward against the face of the hammer. At the same time the finger 52 engages the block 41 turning it forward with the head B. The anti friction roll carried by the head 26 rides up the inclined surface 51 of the post 49 throwing the perforator over toward the center of tne cylinder, the roll descending along the oppositelyinclined face 60, which thus serves as a guide to direct the perforator to the opening in the cylinder, perforatin g the garment laid thereon. With the continued movement of the parts the iingcr 52 strikes the anti friction roll 57 throwing it out of engagement with the block 41, which is instantly thrown backward carrying the perforator out of the path of the hammer. The hammer continues to descend and the plunger 4 is simultaneously thrust upward in the cylinder 3, carrying the rivet to the under side of the garment and through the opening therein, while the hammer brings the button down upon the top of the garment, the rivet entering the opening in the hub of the button, where it is riveted by impact against the boss on the face of the hammer.

I claimn l. In a button attaching machine, the combination of the plunger, the conduit leading thereto, the hammer working toward and from said plunger, the conduit leading to the face of the hammer when raised, means for receiving a button from said conduit and holding it upon the face of the hammer, the spring restrained perforator working in line with said plunger, and means carried by said hammer for actuating it in advance of the hammer, substantially as described.
