FRIEDRIOK W. EVERS, OF ST. LOUIS, MISSOURI.
MACHINE FOR MAKING TENT-PINS.
SPECIFICATION forming part of Letters Patent No. 247,626, dated September 27, 1881.
Application filed July 19, 1881. (No model.)
To all whom it may concern Be it known that I, FRIEDRIGK W. EvERs, of St. Louis, in the State of Missouri, have invented a new and Improved Machine for Making Tent-Pins, of which the followingisa specification.
My invention relates to machines for finishing tent-pins-that is to say, pointing them, cutting the notch, and shaping the head.
In the accompanying drawings, Figure l is a plan view of the machine. Fig. 2 is a vertical longitudinal section, 'and Fig. 3 is a vertical transverse section, of the same. Fig. 4 is a plan view of the machine, with a modified construction of feed-bed.' Fig. 5 is a vertical longitudinal section of the modified machine, and Fig. 6 is a face view of one cutter-head.
Similar letters of reference indicate corresponding parts.
C is the frame of the machine, upon which, in suitable boxes, is itted a'mandrel, a, that is to be driven by suitable power. Upon one end of the mandrel are cutter-heads A B, placed side by side.
The head A, as shown in Fig. 6, consists of a hub carrying two arms having beveled ends, to which cutters b are fixed.
The cutter head B has four arms, two of which carry cutters c, and the other two arms carry cutters d. Between the cutter-heads is a presser bar or plate, e, attached adjustably by screw-and-slot connections e to projections from frame C.
E is the feed-hed, fitted to slide in waysf at one side of the frame O. The upper surface ofthe bed on which the pins are to rest, as represented at l, is inclined crosswise, the side beneath the cutters being` the lower, so that the pins shall be held at the proper inclination to the cutters to form the notch. On one end of bed E is hung a hand-lever, g, in position for being held down upon the pins, so as to clamp them while the bed is being moved forward.
At the side of frame' O opposite the feedbed the mandrel a projects, and carries a hollow cutter-head, D, above afixed bed, h.
The head Dis of conical form internally, and carries a knife or knives, i, fitted in a slot and projecting within the head.
The bed h is fitted with an adjustable slotted rest, 7c, for sustaining the pins when presented to the cutter-head for being pointed.
In operation, the pins or stakes being first got out of propersizeand length and in wedge form, the smallerends are pointed by insertion through the slotin rest 7c into the head D. They are then placed side by side on the bed E, and the bed being then moved forward the head portion of the pins pass beneath the heads A B. The beveled cutters on head A give the required bevel form to the heads of the pins. The cutters d on head B cut out the notch at an inclination, while the cutters c, acting vertically, cut the bottom ofthe notch and complete it. The pins are keptfrom risingby the presser e during the cutting operation.
In place of the sliding bed the endless feeding-apron F (shown in Figs. 5 and 6) may be used. This apron is composed of cross-slats carried by a flexible belt that runsv on rollers m. The slats are placed a short distance apart to receive the pins between them, and the shaft of one roller 'm is driven by gearing from the mandrel a.
Having thus fully described my invention, I claim as new and desire to secure by Letters Patent-` 4 In a machinefor making tentpins,the heads A B arranged on the same end of a mandrel, with a presser-bar, e, between them, the head A having cutters b on the beveled ends of its two arms, and thehead B having two pairs ot' cutters, c d, on its four arms, in combination with a slidin gfeed-bed,for the purpose specified.
