MACHINE FOR MAKING SHOVEL-HANDLES.

Specification of Letters Patent.

Patented Sept. 18, 1906.

Application filed December 28, 1905. Serial No. 293,644.

To au whom zit may concern,.-

Be it known that I, JONATHAN FonsHnY, a citizen ofthe United States, residing at Philipsburg, in the county of Center and State of Pennsylvania, have invented a new and useful Machine for Making Shovel-Handles, of which the following is a specification.

This invention relates to machines for making shovel-handles.

The object of the invention is to provide a machine which will in a rapid and thoroughly practical manner form the D in the handle, iinish the grip, and dress the shoulders on appropriate curves.

lVith the above and other objects `in view, as will appear as the nature of the invention is better understood, the same consists in the novel construction and combination of parts of a machine for finishing shovel-handles hereinafter fully described and claimed.

ln the accompanying drawings, forming a part of this specification, and in which like characters of reference indicate corresponding parts, Figure 1 is a view in elevation of a machine constructed in accordance with the present invention. Fig. 2 is a view in'end elevation looking in the direction of the arrow X, Fig. 1. Fig. 3 is a similar view looking in the direction of the arrow Y, Fig. 1. Fig. 4 is a view in elevation of a handleblank. Fig. 5 is a similar view showing the same when the D-hole has been cut therein. Fig. 6 is a similar view showing the blank when the D-hole and handle-grip have been completed. Fig. 7 is a similar view showing a completed handle.

The machine of the present invention embodies means for cutting the D-hole in the handle of the shovel, means for finishing the grip thereof, and means for rounding and 'iinishing the shoulders of the handle, all these mechanisms being supported upon a common base 1 Mounted in suitable journal-bearings 2, supported by standards 3, rising from the base, is a shaft 4, one end of which carries a cutter 5 for forming the D-hole in the handle and the other end a critter' 6 for finishing the grip of the handle and dressing off the shoulders thereof. As shown in Fig. 1, the cutter 5 is approximately elliptical and is constructed of a sheet or plate of metal, while the cutter 6 is constructed of two plates of metal the cutting edges of which are concaved, thus to give the proper contour to the parts upon which they o erate. The cutters are held combined Wit the shaft by bolts 7, whereby to permit of their ready detachment for purpose of sharpening or the like. In addition to the bearings 2 there is a third bearing 8, provided adjacent to the cutter 5, that is supported by a standard 9, bolted to the upper face of the base. The shaft has combined with it an adjustable collar 10, by which the shaft is caused always to run evenly in its bearings and without any endwise movement. That portion of the base over the cutter 5 is provided with a pair of longitudinal guides or keepers 11, between which is mounted a plate 1 2, to which the standard 9 is bolted, and secured to the under side of the plate is a bar 13, having a downward-extending arm 14, through which projects a screw 15, that freely rotates within the arm and is held from longitudinal movement relatively thereto by a collarl, disposed on one side of the arm, a crank 17 being rigidly secured to the outer end of the screw on the other side of the arm. The screw engages a nut 1S depending from the under side of the plate 12 and projecting through a longitudinal slot 19 in the portion of the base supporting the plate 12, as clearly shown in Fig. 1, whereby upon the screw being turned the plate will be reciprocated upon the base.

`Secured to the plate 12 by bolts 20, that serve to secure the plate 12 and bar 13 together, is a rectangular frame 21, carrying two adjustable centers 22 and 23', the center 22 having combined with it an eye 24, Fig. 2, and the center 23 a crank 25, and by means of the eye and crank the two centers may be adjusted relatively to the frame, as will be clearly understood by reference to Fig. 2, and to lock the centers at their adjusted positions each is provided with a locking-nut 26. In order to brace the frame against any tendency to yield under the pressure to which it will be subjected in use, two bracearms 27 are provided, the forward terminals of which are secured by bolts 28 to the frame 21 and their rear terminals by bolts 29 to brackets 80, bolted to the plate 12. The shaft 4 carries a pulley 31, adapted to be driven by any suitable source of power. (Not necessary to be shown.)

The apparatus thus far described is adapted for cutting the D-hole in the handle, and to secure this result the following procedure is observed: The handle-blank H (shown in Fig. 4) is secured between the centers 22 and 23, as shown by dotted lines in Fig. 2, and the adjusting-screw 15 is then operated to bring the handle into proper position relatively to the cutter 5, and'upon the handle being moved through the arc of a circle onehalf of the D-hole is cut. The handle -is then removed, its position reversed, and the other half of the D-hole is finished, presenting the article shown in Fig. 5, whereupon the handle is removed. The neXt step in the procedure consists in finishing the grip G to give it the rounded contour. This is secured by the mechanism exhibited more particularly in Fig. 3, which consists of a carrier 32 and a support 33, which latter is rigidly supported by a bolt or pivot 34, carried by an arm 35, projecting from the frame of the apparatus, and by an angularly-disposed brace-arm 36, the lower end of which is provided with a foot 37 that is bolted to the upper edge of the support 33, as clearly shown in Fig. 3, the upper end of the brace-arm being secured to a casting 38, rigid with the upper end of a standard 39, the lower end of which latter is secured by a bolt 40 to the frame. The carrier 32 is adapted to rotate upon the bolt 34 as a pivot, as shown in Fig. 3, and is turned through the arc of a circle by a screw 4l, the upper end of which passes -through a threaded openingv in the head 38 and carries at its upper end a crank 42, and the lower end of which is connected by a pivot 43 with a clamping member 44, combined with the carrier 32 adjacent to its forward end, the rear end of the carrier being provided with a clamping member 45. Each of the clamping members has combined with it a clamping-screw 46, each screw being provided with an eye 47, by which to facilitate its turning. The carrier 32 is provided with a flange 48, upon which the handle rests, as clearly shown in Fig. 3. As clearly shown in Fig. 2, the carrier is disposed in the path of movement of the cutter 6. A

The portion of the apparatus just described is that employed when the grip G is to be finished, as shown in Fig. 7. To effect this result, the handle is secured within the clamping members by the clamping-screws 46, and upon rotary motion being imparted to the screw 4l the carrier 32 is caused to move through the-arc of a circle, thereby bringing the outer portion of the handle into engagement with the cutters and causing it to be cut away on a curve, as shown in Fig. 6. Vhen this procedure is accomplished, the handle is removed and subjected to the action of the mechanism for rounding the shoulders S to present a finished product. (Shown in Fig. 7

This finishing mechanism comprises a carrier 49, which is pivotally connected by a bolt 50 with an extension 5l of the frame, the lower edge of the carrier being provided with a flange 52, upon which the grip portion of the handle will rest. Secured to the carrier 49 by a bolt 53 is one arm 54 of a clamping member, the other arm 55 of which is eX- tended in front of the carrier and carries a clamping-screw 56. Rigidly secured to the arm 54 is a standard 57, having a threaded orifice that is engaged by a screw 58, one end of which is provided with a crank 59, and the other end of which projects through an arm 60, secured to the extension 51 by a bolt 61, the screw being held against disconnection from the arm by a nut or washer 62. The carrier 49 is disposed in alinement with the carrier 32, and therefore in operative position relatively to the cutters 6.

The operation of the finishing mechanism of the device is as follows: The handle is secured in position upon the carrier 49 by the clamping-screw 56, .and upon the screw 58 being turned the carrier will be moved through the arc of a circle of which the bolt 50 is the center, thereby finishing the shoulder on one side of the handle. To complete the operation, the handle is removed and its position reversed, and the other shoulder is finished in the same manner.

It will be seen from the foregoing description that although the improvements herein defined are simple in character that they will be thoroughly eflicient for the purpose designed and will in a rapid and practical manner produce finished shovel-handles in condition to be placed upon the market.
