AUTOMATIC CARRIER FOR ELECTRIC WIRES.

Specification of Letters Patent.

Patented Sept. 1

Application filed August 4, 1904. Serial No. 219,526.

To all whom it may concern.-

Be it known that I, FRANK E. DETCHON, a citizen of the United States, residing at Delta, in the county of Delta and State of Colorado, have invented a new and useful Automatic Carrier for Electric Wires, of which the following is a specification. I

This invention relates to devices employed in the stringing of telephone, telegraph, and other wires or cables between buildings, poles,- and other supports where an aerial conductor is usually first stretched between the two points of support and forms a base or support for the carrying of the wires or cables.

The principal object of the invention is to providea small self-propelling carriage which may be mounted on the aerial conductor and may be used to carry wires from one support to another without danger of overturning.

A further object of the invention is to provide a device of this class in which the traction wheel or wheels will be held firmly to the supporting wire or cable, so as to avoid danger of slipping when the carrier is traveling upgrade. I

A still further object of the invention is to provide an improved casing for all of the working partsof the carrier, so that the mechanism of the latter will not be injured by contact with the branches of trees or other obstructions.

A still further object of the invention'is to provide a carrier of such construction as to prevent falling of the carrier from the overhead support incase of derailment.

With these and other objects in view, as will more fully hereinafter appear, the invention consists in the novel construction and arrangement of parts hereinafter fully ,described, illustrated in the accompanyingdrawings, and particularly pointed out in the appended claims, it being understood that vari ous changes in the form, proportions, size, and minor details of the structure may be made without departing from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawings, Figure 1 is a longitudinal sectional elevationof a wirecarrier constructed in accordance with the invention. Fig. 2 is a sectional plan view of the same on the line a a of Fig. 1. Fig. 3 is a transverse sectional elevation of the carrier on the line b b of Fig. 1. Fig. 4 is a detail perspective View of a portion of the I illustrating the flap-locking device.

Similar characters of reference are e ployed to indicate corresponding P3528 throughout the several figures of the draw-. ings.

The main portion of the supportingf of the carrier includes longitudinal bars and 3, the bars 1 and 2 at one side of the i rier being united by vertical bars 4, and bars 2 and 3, which form the lower portii the frame, being united by a series of t1 verse bars 5, 6, and 7.. In addition to the frame is in part formed of a casir which incloses all of the working parts prevents injury to the mechanism from tact with tree branches and other 0%,, tions; This casing is formed, preferal; ,1. sheet metal andis tapered at its froi-.enc and, if necessary, at its rear end. The central portion of one side of the casing is open for its entire length, forming a longitudinal slot 9 to permit the carrier to be readily inserted on the overhead support a. This slot is closed by a flap or door 10, the upper edge of which may be secured to the upper por-i tion of the casing in any suitablemanner, as

by the formation of interfitting tongues 11 on the adjacent edges of the flap or cover,;'

these tongues being provided with openings. for the passage of a wire or rod 12, which when forced, in place serves to firmly lock the fl 'a? in position and hold the parts of the'casim together and at the same time forms a con. plete casing around the overhead support, so that in case of derailment it will be impossi ble for the carrier to fall to the ground.

In the'upper bar 1 of the frame and-in the casing at a point opposite said bar areformed bearings for the support of transversely-dis; posed shafts 15,0n which are mounted'groovedi wheels 16, that are placed on the overhead; support a, and the grooves may be lined with: rubber, leather, or other suitable material in:

Y order to increase the tractive force and avoid j danger of slipping when the carrier is ascending grades. To the shaft of one of the wheels 16 is secured a pinion 17, which intermeshes with a gear 18, formed on or carried by a spring-barrel 19, that is carried by ashaft or arbor 20, also having hearings in the frame and casing. In thespring-barrel isa propelling-spring 21, which is wound by the operator before the-carrier is placed on the sup- BEST AVAlLABLE COP .the purpose of governing the speed rier the gear 18 is connected by a ears 22 to an arbor 23, carrying a .y 24, which will regulate the speed the carrier travels. bar 6 of the lower portion of the .i pivoted two arms 25, connected at .nter'mediate of their length by a cross- These bars are provided with bear- :nings for the reception of a small 27, on which is mounted a roller 28,

adapted to engage the under side of the overh 'ad support a at a point between the two grooved wheels 16, and said roller 28 is held up in contact with the support by means of a .sriring 30, one end of which is secured to the 7; and the opposite end of said spring passing over the bar 6 is placed under cross-bar 26, the stress of the spring beufficient to maintain the carrying-wheels igagement with the support a with suffia force to enable the carrier to ascend es without slipping. ie lower rear portion of the frame mem- 12 and 3 serves as supports for a reel 30, 'rhich a wire, cord, or cable may be wound ycarried bodily from one point to anthe, or the arrangement may be such that me Uhd of,the wire, cord, or cable is secured ,0 one support and is gradually unwound irom the reel as the carrier progresses. The reel is connected by gearing to a shaft 33, having at one end a crank 31 and provided with a spring 34, one end of which is connected to a pin 35, the spring serving to turn the reel in winding up the cableand being in part rewoundas the cable is paid up, so as to hold said cable or wire under tension. This spring inust of course be weaker than the propelling- 7 spring.

locked and the carrier is started, being propelled, by the unwinding of the spring, to the iistant building or pole, at which point a secbnd'operator will remove the end of the wire from the reel and secure it in place and then return the carrier after rewinding for a secand wire.

Having thus described the invention, what 1 is claimed is 1. A wheeled carrier arranged to travel on an overhead support, a casing wholly lnclosing the wheels and movable parts of'the carrier, said casing having a longitudinally-disposed slot for the admission of the support, and a hinged flap or door forming a part of the casing and serving to close said slot.

2. A wheeled carrier adapted to travel on an overhead support, a carrier-casing wholly inclosing all of the movable parts of said carrier, and tapering at its forward end in the direction of said support, the casing being provided with a longitudinal slot for the admission of the support, and a hinged closingflap forming a part of said casing and adapted to close the slot.

3. lnadeviceoftheclassspecilied,aframe,a plurality of supporting-wheels carried thereby and adapted to travel on an elevated support, means for imparting movement to one of said wheels thereby to propel the carrier, a spring-pressed operating-roller arranged to engage the support at a point between said wheels, and an inclosing casing within which all of the movable parts of the device are disposed.

4. The combination with'a spring-propelled wheeled carrier arranged to travel on an overhead support, and provided with a slotted cas ing for the admission of the supp0rt,.means for governing the speed of travel of the carrier, and a spring-wound wire-carrying reel supported by said carrier.

. 5.- The combination with a wheeled carrier arranged to travel on an overhead support and provided with a slotted casing, of a motorspring for propelling the carrier, a wire-carrying reel, and a winding-spring for the reel, said winding-spring being of less strength than the motor-spring.

6. The combination with a frame, of carrying-wheels journaled therein, a spring-wound reel also supported by the frame, a motorspring for propelling the frame, and acasing inclosing the whole'of the frame, wheels, and reel, said casing having a tapered forward end and being provided at one side with a slot for admitting an overhead support.

In testimony that I claim the foregoing as my own 1 have hereto affixed my signature in the presence of two witnesses.
