Application filed; December 16,)1918, $erial No. 267,034. Renewed March 10, 192 1.

To all whom it may concern: Be it known that I, WILLIAM ERASTUS WILLIAMS, a citizen of the United States, and a resident of Wilmette, county of Cook, and State of Illinois, have invented anew and useful Improvement inSplint Carriers for Match Machines, of which the following is a specification.

The object of my invention is to lighten the weight and lessen the cost of the splint carrier used in modern match making machines and the invention is set forth inthe claims. Reference will be had to the accompanying drawing in which:

Fig. 1 is a plan, Fig. 2 a side and Fig. 3 an end view of a section of a splint carrier.

Fig. 4 is a sectional view, on an enlarged scale, showing the plate of the splint carrier being acted upon by dies and this constitutes the first operation in perforating the plate for carrying the splints.

Fig. 5 shows the dies and second operation.

Fig. 6 shows the third operation and Fig. 7 the last operation.

Fig. 8 shows on an enlarged scale some match sticks or splints stuck into the carrier.

plate in the Fig. 9 shows the punches that discharge the'matches from the carrier and this also is on an enlarged scale.

The match carriers that are generally used in the best machines are composed of perforated metal belts made up of links or sections of plates hinged together forming continuous endless carriers and the ends of the splints are forced into the perforations of the plates and are thus held for dipping and drying. p

The sections of the metal belt have been made of iron and steel and are usually from three sixteenths to one quarter'of an inch thick while the holes or perforationsinto which the splints are stuck are about one tenth of an inch in diameter.

It is impracticable to punch the perforations in metal that isthick enough to make a hole deep enough to properly hold the match sticks or splints. By my method of working in the holes in the metal I succeed in getting a hole the right depth to make a secure seat for the splint when using a plate one sixteenth of an inch or less thick. The, holes have necessarily been drilled in the old style plates while I may punch my holes and thus saveenormously on the cost of making the carrier. V l I As my. carrier weighs less than onethlrd of the old style carriersfithere is a saving in or carrier section for the splints. This plate is made of thin metal andhas a flange 2 turned all aroundon its margin.

3 indicates rack teeth link bars secured to the ends of the plates by any suitable means such as rivets spotwelds or brazing or welding, not indicated in the drawing. The flange 2 of theplate 1 isimbeddedin slots in the links 3 in order to retain the general all around stiflness of the plate 1. By means of the links 3 the plates are connected into an endless carrier as desired. With same machine theplates are made larger and used more or less independently.

In Figure 1, & indicates the top die, 5 the lower die and 6 the punches that acton the plate and turn the flange 2 and emboss the cup shaped indentures 7 i in the plate 1. These dies and punches cover an entire section in one operation. Were I to punch one hole or indenture at a time or. one line of them at a time the operation of the next hole Iorline of holes would distort the previously formed ones and make impossible the accurate registry required for the punches in dischargingthe matches.

By pressing the cup shaped indentures 7 as indicated I draw down the metal from the flat surface of plates providing for sufflcient stock forholes of the right depth to hold splints.

In the second operation Figure 5 with as indicated by 19. However if the holes are made sufficiently accurate to each other and suitable dies 8 and 92nd punches 10 I narthe dischargin punches are likewise accurate this last fianging operation of Fig. 7 may be omitted.

20 indicates the splints held in the carrier and iii-Figure 9, 21 indicates a series of punches adapted to enter the perforations and discharge the splints. The flanges or countersinks 19 guide slightly the entry of the punches 21 as they approach to discharge the matches in the normal operation of the match machine. I

Were I to undertake to draw down a hole of'the depth required without first embossing'a large cup as indicated by 7' the metal would tear out and give a hole but little if any deeper than the thickness of the plate.

After the deep large cups have been embossed and closed in I may pierce the holes by drilling instead of punching them and thus substitute drilling for the operation shown by Fig. 6.

What I claim is z- 1 1. A match carrier plate of sheet metal having at its lateral margins integral stiffening flanges and having its body provided with numerous splint receiving perforations each surrounded by an integral annular flange.

'2. A match carrier plate of 'thin sheet metal having at its lateral margins integral stiffening flanges, having its body provided with splint receiving perforations each surrounded with an integral annular flange on one face of the plate, and having each of its ends rigidly heldv by transverse laterally projecting link bars.
