SPECIFICATION forming part of Letters Patent No. 786,643, dated April 4, 1905.

' Application filed April 15,1904. Serial No. 203,287-

To a whom it may concern:

Be it known that I, EDWIN A. HALLAM, a citizen of the United States, residing at Macon, in the county of Bibb and State of Georgia, have invented new and useful Improvements in Conveyers, of which the following is a specification.

This invention relates to conveyors particularly adapted for elevating and conveying logs.

Primarily the invention resides in the trolley-carriage operating upon a cableway, said carriage carrying what may be termed the drum for the receding rope, the drum for the pulling-rope, and the drum for the lifting-rope, said drums being operatively connected together,

The invention further aims to provide the carriage with a suitable brake for holding the carriage stationary, if desired, and to further provide means to permit of the receding drum operating in either direction when occasion requires,and said means is further adapted to lock the receding, lifting, and pulling rope drums together to prevent the movement thereof.

The invention further aims to provide a new and novel form of conveyer which when set up will dispense with the separate gripping device employed in conveyers for logging purposes, said gripping device generally being arranged adjacent to the trolley-carriage, to further dispense with the cable between the gripping device and the trolley, and to further dispense with the ordinary outhaul-rope and its drum generally employed in conveyers for logging purposes.

The invention further aims to construct a conveyer device especially adapted for logging purposes which shall be simple in its construction, strong, durable, efiicient in its use, and comparatively inexpensive to manufacture.

With the foregoing and other objects in view the invention consists of the novel combination and arrangement of parts hereinafter more specifically described, illustrated in the accompanying drawings, and particularly pointed out in the claims hereunto appended.

In describing the invention in detail reference is had to the accompanying drawings, forming a part of this specification, wherein like reference characters denote corresponding parts throughout the several views, and in which Figure 1 is an elevation showing the general operation of the device. Fig. 2 is a side elevation of the trolley-carriage broken away. Fig. 3 is a sectional plan of the trolley-carriage on line 3 3 of Fig. 4. Fig. 4 is an end view of the trolley-carriage. Fig. 5 is a sectional detail view of the trolley-carriage. Fig. 6 is a side elevation of the trolley-carriage broken away, and Fig. 7 a detail of one of the plates of the trolley-carriage.

The conveyor is shown as in use upon a cableway, although it will be evident with only slight or no modifications the conveyor might be used upon a rigid track instead of, as shown, a cable.

Referring to Fig. 1 of the drawings, a headsupport is indicated by the reference character 1 and a tail-support by the reference character 2. These supports are in the form of upright posts and have the cableway 3 suitably connected thereto, as at 4 5. Any form of connecting means between the cableway and supports 1 2 may be employed. In Fig. 1 of the drawings the reference character 6 denotes the trolley or conveyer carriage operating upon the cableway The carriage 6 will be hereinafter more specifically described. In Fig. 1 of the drawings the receding or outhaul rope is indicated by the reference character 7, the pulling or inhaul rope by the reference character 8, and the elevating or carrying rope is indicated by the reference character 9. The receding or outhaul rope 7 passes at its forward end over a pulley or sheave 10, suitably secured to the support 1, and at its outer end passes over the pulley or sheav l1, suitably connected to the support 2. The pulling or inhaul rope 8 passes over a pulley or sheave l2, suitably connected to the support 1. 13 denotes a winding-engine provided with the drum 1% for the outhaul-rope and the drum 15 for the inhaul rope or cable. The manner of connecting the ropes or cables 7, 8, and 9 to the trolley or conveyer carriage and the manner in which the ropes or cables 7, 8, and 9 operate will be hereinafter referred to.

Referring to Figs. 2 to 6 of the drawings,

YES 6 13- the trolley-carriage 6 consists of a pair of outer plates 16 17 and an intermediate plate 18, the said latter plate being arranged nearer the outer plate 17 and divides the carriage into two compartments 19 and 321i. Within the compartment 19 is arranged the drums for the ropes 7 8 9, and within the cmnpartment 20 is arranged a train of gearing for the various drums, as well as a ratchet mechanism. for the receding-rope drum. The in termediate plate 18 and side plate 16 are of greater height than the outer plate 17 and at their upper ends converge inwardly toward each other, as at 21, and then extend upwardly in a vcrtici l manner, as at 2,2. The upper end of the outer plate 17 is bent inwardly, so as to engage the portion 21 of the intermediate plate 18, and the said plates 16, 17, and 18 are bolted together through the medium of suitable hold fast devices in the form of elongated bolts, as at 23 2 the bolts extending through the upper portions of the plates 16, 17, and 18. Between the plates 16 and 18, near their upper ends, is arranged a brace-block, preferably of wood, as indicated by the reference character 25, and through said block extends the bolts 23 and 2 1. Between the plates 17 and 18, at their upper ends, is arranged a braceblcck 26, preferably of wood, and through said blocl: extends the bolts 2 it may be stated that any number of holdfast devices,

such as the bolts 23 and 2 1, can be employed.

Journaled in the top of the carriage 6 between the portions 22 of the plates 16 and 18 and at each end of the carriage 6 is a trolley-- wheel 27, traveling upon the cable 3. The carriage 6 when mounted in position is sus pended upon the cable 3, as shown in Fig. *1. A suitable frictional braking means is employed for retaining the trolley in any position desired, and said braking means consists of a pair of rollers 28, secured between the portions of the plates 16 18 and above the cable 3. A brake-block 29 interposed between the rollers 28 and arranged above the cable 3. A cam 30 is arranged below the rollers :28, block 2%), and cable 3. The cam 30 is pivoted in the keeper 31, secured to the brace-block 9.5, the latter being recessed for such purpose, as at is operated by moving the cam 30 in such a manner so as to cause the clamping of the cable 3 between the rollers 28, block 29, and cam 30. The cam 30 is of such weight that it will return to its non-braking position by gravity, and said cam 30 is operated through the medium of an outwardly-extending protuberancc 33, projecting through a curved slot B l in the plate 16 and connected to an operatii'ig-rope 35, which travels between a pair of guide and friction rollers 36, secured to the outer face of the plate 16. Suitable means can be employed for protecting the rollers The reference character 37 denotes the drum The braking means.

for the receding rope 7, one end of said rope 7 being fixedly secured to said drum 37, and said rope 7 is adapted to wind upon and unwind 011' said drum 37. The drum 37 is lixed upon a shaft 38, which is journaled atits ends in the plates 16 and 17. The length of the drum 37 is such that it extends within the intermediate plate 18, a suitable opening 39 being provided for such purpose. That end of the drum which extends in the opening 39 has secured to it a gear-wheel 10, which in turn has secured thereto a ratchet-wheel 11. The ratchet-wheels]. is adapted to be engaged by a pawl i2, so as to prevent the drum 11 turning in both directions as long as said pawl 1-2 engages with the ratchet 41. The pawl is pivotally secured to the inner face of the plate 17, as at 13, and has its outer end somewhat elongated, as at 4A. Said end 1 1 of the pawl a2 is adapted to be engaged by an eccentric 15, so as to disengage said pawl from the ratchet 11. The eccentric 1-5 is operated so as to move the pawl from its engagement with the ratchet 41 through the medium of the rope s6, and said eccentric 4:5 is operated so as to permit of the return of the pawl to engage with the ratchet a1 through the medium of a rope 47 passing over the pulley .8. The eccentric 4-5 is pivoted, as at 4:9, to the inner face of the plate 17 and has connected H101:- with a handle 50, to which are attached the ropes a6 and 4:7. may be stated that the pulley 18 is secured to the inner face of the plate 17. The pawl 42 is normally retained in engagement with the ratchet 11 through the action of a flat spring 51, secured to the inner face of the plate17, as at 52.

The reference character 53 denotes the d rum for the pulling or inhaul rope 8, said rope 8 having its end fixedly secured to the drum 53, and said rope 8 is adapted to wind and unwind upon and oil said drum The drum 53 is of such length as to have one end extend in the plate 18, and for this purpose an opening 5% is provided. That end of the drum which projects into the opening 54; has secured thereto a gear-wheel 55, and said gear-wheel 55 meshes with a pinion 56, which in turn meshes with the gear 10, carried by the d r m 37. The pinion 56 is mounted in the comps tinent 20 and is journaled in the sliding bearing 57. (See Fig. 5.) The plate 18 is cut away, as at 58, to provide for one side of the hearing 57, and the plate 17 has secured to its inner face a guideway 59 for the other side of the bearing 57. A yoke 60 is secured to the bearing 57 and carries an adjusting-screw 61, operating through the guide '2. By such a construction it is evident that the pinion 56 can be moved away from the gears 10 and 5, so that when it is desired the drums 37 and can be operated independently of each other.

The reference character 63, Fig. 3, denotes the drum for the lifting or carrying rope 9, said rope 9 having its end fixedly secured to ries on its free end the tongs 69.

1 is shifted so the drum 63, and said rope 9 is adapted to wind for the drums 53 and 63 are journaled in the plates 16 and 17.

The receding or outhaul rope 7 winds upon and off the drum 37 from the top and on its passage back to the drum 14 does not pass through the trolley or conveyer carriage 6, but at the side thereof, and for such purpose the guide-pulleys 68 are provided, the rope passingbetween the said pulleys. The pulling or inhaul rope 8 winds on and off the drum 53 at the top thereof, and the lifting or carrying rope winds on and off the drum 63 at the side thereof, and when the conveyer is employed for logging purposes the rope 9 car- (See Fig. l.)

as f llows:

The operation of the device is Assuming that the carriage has been pulled out to the position shown in Fig. 1 through the operation of the drum 14, the pawl 42 as to be free of the ratchet 41. The drum 14 is further operated so as to unwind the rope of the drum 37, such action rotating the drum 37, which in turn will cause the operation of the drum 53, winding the pulling-rope thereon from the drum 15. The operation of the drum 53 will in turn operate :the drum 63, throwing out the lifting or carrying rope to which is attached the tongs 69. iBefore the pawl 42 is moved out of engagelment with the ratchet 41 the brake is thrown ;on, so as to retain the carriage stationary. After the tongs 69 have been connected to the {object desired to be conveyed the brake is released and the pawl thrown into engagement iwith the ratchet. The drum 15 is operated, pvhich causes the rotation of the drum 53, and ,the object is lifted, owing to the operation of the drum 63 through the medium of the drum The continued operation of the drum 15 {will cause the carriage to be moved to the poisition desired upon the trolley-wire 3. When lthe carriage arrives at the position desired, the brake is again placed into operation, the lpawl released, the slack is taken up in the rope 17, the rope. 8 slacked, and the object transported will be lowered by gravity.

Although the device is shown provided with the pinion 56, yet it is evident that said pinion can be dispensed with and the drums directly geared with each other. When the pinion 56 is dispensed with, a reversal of the ropes on the lower drums will be necessary.

, I t is thought that the many advantages of a conveyer constructed in accordance with the foregoing description can be readily understood, and it will furthermore be evident that changes, variations, and modifications can be resorted to without departing from the spirit of my invention or sacrificing any of its advantages, and I therefore do not wish to restrict myself to the details of construction hereinbefore described and set forth in the annexed drawings, but reserve the right to make such changes, variations, and modifications as come properly within the scope of the protection prayed.
