CARL EDWIN WALLGREEN, OF ADAMS, NORTH DAKOTA.

AUTOMATIC WIRE-REEL.

Specification of Letters Patent,

Patented Feb. 25, 1908.

T 0 all whom it may concern:

Be it known that I, CARL EDWIN WALL- GREEN, a citizen of the United States, residing at Adams, in the county of Walsh and State of North Dakota, have invented cer tain new and useful Improvements in Automatic Wire-Reels; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to new and useful improvements in automatic wire reels, and my object is to provide means for transportmg a reel and wmdmg wire thereon, or paying the same therefrom.

'A further object is to provide means for rotating the reel in either direction.

A further object is to provide means for positively driving the reel.

A further object is to provide means for yieldingly mounting the reel upon the carrying frame, and a still further object is to provide means for releasing the reel, so that the same may be removed from its supporting frame.

Other objects and advantages will be hereinafter referred to and more particularly pointed out in the claims.

In the accompanying drawings, which are made a part of this application, Figure 1 is a side elevation of my improved reel and carrying frame therefor. Fig. 2 is a top plan view thereof. Fig. 3 is a rear elevation of the same. Fig. 4 is a detail view partly in section of the reel, showing means of detaching the same from its supporting frame. Fig. 5 is a side elevation of the reversing gear for the reel, showing parts thereof in section, Fig. 6 is a detail view partly in section showing a portion of the supporting mechanism for the reel. Fig. 7 is a detail sectional view, as seen on line 7-7, Fig .3, and Fig. 8 is a detailed sectional view as seen on line 88 Fig. 6.

Referring to the drawings, in which similar reference numerals designate corresponding parts throughout theseveral views, 1 indicates a frame which is preferably U- shaped, and has secured to the lower ends thereof oppositely disposed tubular sockets 2, which are fixed to the frame, and receive supporting axles 3, upon which are mounted suitable carrying wheels 4.

Rotatably mounted on the axles 3 and between the sockets 2 and carrying wheels 4 are bevel gears 5, the hubs 6 of which are provided with teeth 7, which are adapted to engage similar teeth 8 on the hubs of the Wheels to form a clutch, whereby the bevel gears will be driven in one direction when the teeth on the wheels are in engagement with the teeth on. the bevel gears, and in order to normally hold the teeth on the wheels in engagement with the teeth on the bevel gears, I dispose around the extended ends of the axles 3 springs 9, one end of which engages the outer end of the wheel hub, while the opposite end thereof engages a propelling frame 10 fixed to the ends of the axles, thereby exerting inward pressure on the wheels at all times.

The lower ends of the frame 1 are directed inwardly to form horizontally disposed ledges 11, on which are mounted guides 12, said guides having longitudinally extended ways 13 therein, in which are mounted heads 14 the upper and lower edges of which are tapered from the center of the head to each edge thereof, and the bearing faces of the ways 13 are correspondingly constructed, so that when the heads are seated in the ways, said heads will be held against lateral movement.

Each of the heads is provided with an opening 15, in which are adapted to take pivot pins 16 carried by a reel 17. The reel 17 is constructed from the usual, or any preferred form of disks 18, which are secured together by means of a tubular axle 19, the pivot pins 16 being seated in the tubular axle and adapted to protrude a sufficient distance through the disks 18 .to enter the openings 15 in the heads 14, and as the reel proper snugly fits between the guides 12 the pivot pins 16 are longitudinally movable in the axle, so that they can be drawn into the axle and the outer ends thereof removed from engagement with the heads 14, so that the reel can be quickly inserted or removed from position.

The pivot pins 16 are normally held in their outward position by means of springs 20, said springs being spiral and surrounding the pivot pins, one end of the springs being seated against a portion of the axle 19, while the opposite ends thereof are fixed to the pivot pins, in which position the springs will direct outward pressure at all times on the pivot pins. A cable 21 is extended longitudinally through the axle 19 and is secured to the pivot pins 16 in any preferred manner, as by directing the ends of the cable through openings in the inner ends of the pins and twisting the free. ends of the cable around the remaining portion of the cable to form loops, and in order to readily move the pivot pins longitudinally into the axle 19, an auxiliary cable 21 is secured at one end to the cable 21 and substantially at its longitudinal center, the auxiliary cable 21 extending to one end of the axle 19 and through a bore 22 formed at the intersection of the axle with one of the disks 18, and then upwardly to the outer edge of the disks, so that the auxiliary cable may be readily grasped and a pull given thereon, and in order to cause both of the pivot pins 16 to move inwardly simultane ously, the auxiliary cable is passed over a pin 23 extending laterally through the axle andbetween the connection point of the cable 21 and auxiliary cable 21 and that end of the axle to which the auxiliary cable extends, by which construction the two ends of the cable 21 will be moved towards each other when a pull is given to the auxiliary cable 21 In order to obviate any sudden jerks or jars upon the reel when the wire is being wound thereon, or paid therefrom, I mount auxiliary heads 2 1 in the ways 13, and adjustably secure the same therein, by directing a threaded bar 25 through a threaded opening in the end walls of the guides 12, and between the heads 14 and auxiliary heads 24, I mount a tension spring 26, and by moving the bars inwardly or outwardly, the tension of the spring will be accordingly increased or decreased.

The reel 17 is driven from the bevel gears 5 through the medium of driving shafts 27, said shafts extending through the tubular sockets 2 and the inner ends of the axles 3, and are held against longitudinal movement by placing collars 28 thereon andat each side of the tubular sockets 2.

Longitudinally movably mounted. on the driving shafts 27 are oblong frames 29, on each of which are rotatably mounted

beveled pinions

30 and 31" at each end of the frame, said 'inions being adapted to mesh with the beve gears '5, and thereby rotate the driving shafts 27, said pinions being secured to the driving shafts by the usual form of feather 32, thereby causing the driving shaft 27 to rotate with the pinions and at the same time allow the pinions and frame supporting the same to move longitudinally on the driving Shafts.

Secured to one end of the driving shafts 27 are friction pulleys 33, which are adapted to engage the outer faces of the disks 18 and rotate the reel when power is applied to the bevel gears 5. I

The object in providing the bevel gears at opposite ends of the driving shafts 27 is to enable the operator to reverse the rotation of the reel when desired and it will be seen that when the beveled pinions 30 are in mesh with levers 34, and it will be seenthat when the levers 34 are swung from side to side, the frames 29 will be correspondingly moved longitudinally and the pinions moved into or out of engagement with the bevel gears 5. The levers 34 are provided. with the usual or any preferred form of spring operated latches 37, which enter depressions 38 in the outer peri heries of the tubular sockets 2 and holdthe evers in their adjusted position. When wire is being wound on the reel 17., the pinions 31 are moved into engagement with the gears 5, so that when the device is moved forward towards the strand of wire, .the reel will readily wind the wire thereon, and when it is desired to unwind the wire from the reel, or pay out the same, the levers 34 are shifted to move the pinions 30-into engagement with the bevel gears 5, which will result in rotatin the reel in the opposite direction. It wil thus be seen that I have provided a very convenient means for transporting the reels of wire from place-to place and stretching the same along the line of fences, or for winding the wire on the reel after the wire has been removed from position on the fence. post. It will also be seen that I have provided'positive means for rotating the reel to causethe wire to wind thereon.

What I claim is:

1. In a device of the'class described, the combination with a frame, having supporting wheels therefor; of a reel, guides on said frame, heads in said guides, having openings, pivot pins carried by said reeladapted to enter said openings and pivotally mount the reel on the frame, means to normally hold said pivot pins in said openings, and means carried by the reel to move said pivot pins longitudinally, whereby thereel may beremoved from the frame.
