v SKEWER-POINTING MACHINE.

Specification of Letters Patent. 1

Patented Mar. 14, 1916.

Application filed January 15, 1915. SerialNo. 2,414.

To all whom it may concern Be it known that I,ALMON I. SPINNEY, a citizen of the United States, residing at Allens Mills, in the county of Franklin and State of Maine, have invented certain new and useful Improvements in skewer-Pointa machine of this character embodying a r0- tary cutter and a novel type of feeder of annular formation for feeding the pins or cutter.

Another object 1s the provision of a machine of this character embodying novel and eflicient means for imparting rotational movement to the pins during their movement past the rotary cutter to insure accurate pointing of the pins. y With these and other objects in view, the inventionconsists in the novel construction, arrangement and formation of parts as will be hereinafter specifically described, claimed and illustrated in the accompanying drawings, in which:

Figure 1 represents a front elevation,I partly in section, of the machine. Fig. "2 represents an end elevation thereof. Fig. 3 represents a transverse vertical sectional view on the line 33 of Fig. 1. Fig. 4 represents a top plan viewof the machine, partly in section, and Fig. 5- represents an enlarged fragmental detail view of the cutter and feeder mechanism. 1 Referring to the drawings in detail,wherein similar reference numerals designate corresponding parts throughout the several views, the numeral 5 indicates generally a suitable frame structure including a plurality of corner posts 6 and longitudinal and transverse side and ends rails 7 and 8 re- A. suitable drive shaft 9 is rotatably supported in the lower portion of the frame 5 and carries a friction Wheel 10 adapted to mesh with the wheel 11 keyed on a shaft 12 rotatably mounted at one end in i a relatively stationary bearing and supported at its opposite end in a lever 13 having a handle 14 at its upper end and pivotally secured at 15 in the lower portion of the frame structure, whereby when the lever is operated the relatively large friction wheel 11 is move into and out of mesh with the smaller wheel 10. v

A pair of spaced rollers 16 are mounted upon shafts 17 rotatably sup )orted centrally within the frame 5 x A fee ring -18 of annular formation is supported upon the pair of rollers 16 and is formed with a plurality of transverse peripheral recesses or grooves I 19 adapted to receive the ins disposed Within the hopper 20. The bottom wall 21 of the hopper is inclined so as to feed'the pins downwardly to the feed ring 18 by gravity and is also recessed to receive the ring.

' A shaft 22 is rotatably mounted in suitable bearings secured in the upper portion of the frame structure 5 and carries a pulley 23 over which is trained a belt 24 passin over a pulley 25 on the feed ring drive sha t 26 rotatably supported in the frame structure 5 intermediate the shafts 12 and 22. The shaft 26 is extended to a point adjacent the center ofthe frame structure and carries a wheel or pulley 27 frictionally engaging the inner concave surface of the feed ring 18 for imparting rotary motion to the latter during the operation of the machine.

The shaft 22 is driven fromthe shaft 12 by a belt 28 trained over pulleys secured upon these shafts. The inner end of the shaft 22 passes through the ring 18 and a pair of spaced rollers or disks 29 are secured thereon and arranged upon opposite sides of the ring 18 and are adapted to engage the pins in the grooves 19, as clearl illustrated in Fig. 5. A second pair of re] ers or disks 30 are arranged above the disks or rollers 29 and are keyed upon a shaft 31 rotatably mounted within the free ends of a substantially U-shaped rocker frame 32 pivotally supported upon a shaft 33, mounted in the upper ends of a pair of supports 34:,

'over a pulley carried by the lower shaft 12.

The upper pair of disks or rollers 30 are driven from the shaft 33 by a train of gears 37.

A cutter shaft 38 is rotatably mounted in the upper portion of the frame structure 5 and is disposed longitudinally of the latter and carries a cutter head 39 in which is ara form points thereon.

ranged a plurality of cutter blades adapted to engage the ends of the skewers 40 pos1- tioned in the grooves 19 in the ring 18 to mally retained in close relation to the lower pair of disks 29 by the tension of a spring 42 disposed between a bracket 43 carried by the frame structure 5 and the web portion of the rocker frame 32 and coiled about a bolt 44 slidably mounted in the bracket 43 and web portion of the rocker frame 32.

' The upward movement of the adjacent end of the frame 32 is limited by an adjustable nut threaded upon the bolt 44 and the tension of the spring 42 against the web portion of said frame may be varied by ad usting a nut 46 also threaded upon the bolt 44'.

What is claimed is 1. Apointing machine comprising a frame structure, a hopper supported in said frame structure, a feed ring rotatably supported in said frame structure adjacent said hopper and having a plurality of peripheral transverse grooves, a rotary cutter arranged adjacent said feed ring, a shaft rotatably mounted in said frame structure and eX- tending through said feed ring, a air of disks non-rotatably secured on sai shaft a second shaft rotatably mounted in said frame structure, a U-shaped member pivotally supported on said second mentioned shaft, a pair of disks rotatably mounted in said U-shaped member and disposed above said feed ring, and driving connections between the second mentioned shaft and the second mentioned pair of disks.

2. A pointing machine comprising a frame structure, a feed ring rotatably supported in I said frame structure and having a plurality of peripheral transverse skewer receiving grooves, a rotary cutter arranged adjacent 7 said feed ring,

. a pivoted member supported in said frame structure,

. disks rotatably The cutter shaft 38- structure, a

mounted in the inner extremity of said piv- 1 oted member, and means cooperating with said disks to guide skewers past said rotary cutter.

3. A pointing machine comprising a frame feed ring rotatably supported in said frame structure and having a plurality of peripheral transverse skewer receiving grooves, a rotary cutter arranged adjacent said feed ring, a U-shaped member pivotally supported in said frame structure, a pair of disks rotatably mounted in the inner extremity of said U-shaped member, and a pair of disks rotatably mounted in said frame structure below thefirst mentioned disks.

4. A pointing machine comprising a frame structure, a feed ring rotatably supported in said frame structure and having a plurality of peripheral transverse skewer receiving grooves, a rotary cutter arranged adjacent said feed ring, a U-shaped member pivoted centrally in said frame structure, a pair of disks rotatably mounted in the inner extremities of the parallel portions of said U- ,shaped member, and a pair of disks rotadisks and arranged upon a relatively static-nary axis.

In testimony whereof I hereby afiix my signature in presence of two wltnesses.
