JOHN H; WILSON, OF SAN MATEO, CALIFORNIA.

CABLEWAY-GABRIER.

Specification of Letters latent.

Patented Uct. 2a, rare.

Application filed February 23, 1916. Serial No. 79,830.

To all whom it may concern:

Be it known that 1, J H H. VVILsON, a citizen of the United States, residing at San Mateo, in the county of San Mateo, State of California, have invented a new and useful Cableway-Carrier, of which the following is a specification in such full and clear terms as will enable those skilled; in the art to construct and use the same. i

This invention relates to a carrier for cable ways capable of operating a load and to, traverse the cable way by operating from a single hoisting cable, means being provided for releasing and for engaging the hoisting hook upon its arrival at either end of the cable Way.

It will be understood that while the term cable way has been used herein that it is also possible to provide a rigid elevated track for the support of this apparatus, the operation in that case being substantially the same as with a cable, except that for present purposes a special carriage is used when a rigid track is employed.

An embodiment of the invention is shown in the drawing in which the same reference numeral is applied to the same portion throughout, but I am aware that there may be many modifications thereof.

Figure 1 is a side elevation of the complete apparatus, the cable way being shown horizontally instead of inclined for convenience of illustration, Fig. 2 is a vertical sectional view of the carrier on the line 2-2, Fig. 1 looking in the direction of the arrows adjacent said line, Fig. 3 is :1 vertical sectional view of the carriage, the supporting hook being shown in edge elevation looking in the direction of the'arrows on the line 3443, Fig. 1. Fig. 4 is a side elevation of the complete apparatus as used in conjunction with a rigid track, said track also being shown level instead of inclined for convenience of illustration, and Fig. 5 is a view in elevation of the apparatus shown in Fig. 4 looking in the direction of the arrows on the line 5-5, Fig; 4.

It will be understood by those skilled in the art that this carrier is intended to be used in conjunction with an inclined cable way where the inclination is sufliciently great to cause the carrier supporting the bucket or fork to travel away from the winding drum.

The numerals 1 and 2 indicate suitable posts from which a cable? is suspended,

said cable affording a track for the carrier.

The carrier comprises two duplicate rectan gular frames consisting of a top piece 4, bot-, tom piece 5 and three connecting vertical bars 6, 7, and 8. The two frames are suitably bolted 'together and are held a given distance apart by means of the spacers 8.", 9 and 10 which surround the bolts connecting the two frames together. At the upper corners of the frames there are two pulleys 11 and 12 which ride on the cable 3 and thereby support the carrier. At one lower corner ofthe frame which in practice is the upper lower corner there is a pulley 13 for the hoisting cable 14.

The two bars 5 have two depending plates 16: and 16 connected therewith, which plates have a V notch in their lower edges and a deep slot to direct the course of the hoisting block into position in front of the hook bar 17 At the front the plates 16 and 16 have two downwardly extending bars 18 and 19 which carrya' small roller 20 for control: ling the direction of the cable 14. The cable 14 has one end secured to a pin 21 and it passes through a guide ring 22 under the pulley 23 of a block 24. This block has a guide ring 25 surrounding the two parts of the cable at the upper portion of the pulley and it has a hook 26 for connecting the block with the bail 27 of a suitable scoop 28 or other hoisting apparatus. At the upper end of the block 24 there is a bar 29 which is adapted to engage a bar 30 pivoted to the lower bars of the frame at 31. After en gaging the bar 30 the rod 29 comes in contact with the hook on the lower end of the bar 17 and will remain connected therewith since the bar 30 lifts another bar 32 which has a pin 33 extending between the two bars 6 and"? for the purpose of disengaging the hook 34 from the pin 35.

Suspended on the cable at the end away fronr the hoisting apparatus is a block 36, said block having suitable bolts 37 to connect it with the cable and it is provided with the bar 34 which is normally held down against the set screw 38 by means of a spring 39. The set screw 38 is carried by a bracket 40 and is used for the purpose of adjusting the position of the bar 34 so that it will always remain properly engaged with the pin 35 when the carriage strikes the block. The bar 17 has a rod 41 pivotally connected therewith and it extends between two pins 4% and 4 he length 9 hsi' 41 i e 1 adjusted that when the carrier strikes the bumper 36 the hook 17 will be released from the fall block and permit the descent of the bucket, but as soon as the bucket starts the descent of the hook 34 will hold the carriage from shifting its position. The bar 17 is held normally in the position shown in Fig. 1 by. means of a stiff spring 44 and at its upper end the hook has a bar 45 connected therewith which extends forwardly to a lever 46 pivoted to a forwardly extending bracket 47 connected with the bar 8. The lever 46 has a pin 49 and the bracket 47 has a pin 50. On the cable at the hoisting end is a block 51 which has a pivoted hook 52 carried thereby and which hook is held normadly in the position shown in Fig. 1 by means of a stiff spring 53. A hand cable 54 is used to release the hook 53 when necessary. The cable 14 passes over a pulley 55 on the post at the hoist.

In operation the carriage will ride down hill to the block 36 and when the rod 41 strikes said block the hook 17 will release the pin 29 and allow the bucket to descend to be loaded. At the same time the hook 34 will engage the pin 35 and will hold the carriage in position for the bucket to be loaded, while as soon as the bucket is loaded and is hoisted the pin 29 will contact with the bar 30 and thereby disengage the hook 34 from the pin 35 thereby allowing the carriage to begin to travel toward the hoist, but at the same time the hook 17 has been engaged with the pin 29 and the bucket will remain suspended being pulled along by the cable 14. If it is not desired to bring the bucket up to the mast 1 it may be dumped at any convenient position by the use of suitable apparatus, a self-dumping bucket such as is shown in my co-pending application Ser. No. 78,100 filed Feb. 14, 1916, being'used for this purpose, but if it is desired to lower the bucket before dumping the carriage is drawn up until the pin 49 engages the stop block 51, whereupon the hook 17 will release the bucket and at the same time the carriage will move back far enough to permit the hook 52 to engage the pin thereby holding the carriage at the upper end of the cable way while the bucket is being loaded for dumping. WVhen the bucket has been dumped it will be again hoisted and the spring 44 is made sufficiently heavy to prevent the pin 49 from causing the hook to be disengaged when the bucket is hoisted so that as soon as it is again connected with the carriage the hook 52 may be released by pulling the hand cable 54, whereupon the carriage will be ready to move down on the cable way for another trip.

I In order to make the apparatus adaptable for use. with rigid rails the carriage shown in Figs. 4 and 5 is used. In these figures the numeral 60 represents a rigid rail pivotally supported by suitable legs (51, only the upper portions of which are shown in Fig. 4, at one end and by similar legs or a cable 62 at the other end. This rail has angle iron tracks 63 and 04 on its upper corners and it is capable of turning with respect to the cross bar 61 on the pin 61. The track supports a carriage formed with two inverted U shaped members (35, 66. These two inverted U shaped members are connected by means of four bars 67, (38, 69 and 70 which bars hold them in the position shown in Fig. 4. At the upper end of the U shaped members there are four wheels 71, 72, 73 and 74 which ride on the angle bars on the upper edge of the rail. The U shaped members are bolted together by means of bolts 75, 76-=and they have two depending rings 77, 78 which rings are connected with the hoisting carriage shown in the preceding figures by removing the wheels 11 and 12 and passing the bolts through the rings instead of the wheels. The block 36 is then suspended from the track by means of two eyebolts 80, 81, a rod 81 taking the place of the cable and the block 51 is suspended from the opposite end of the track by means of two eyebolts 82, 83, a rod 82 taking the place of. the cable at that end of the track.

The operation of the apparatus is substantially identical with the operation of the preceding apparatus when used in connection with the cable way, except that the rails upon which the auxiliary carriage is mounted are rigid and the tripping blocks are suspended lower than with the other form of cable way.

Having thus described my invention what I claim as new and desire to secure by Letters Patent of the United States, is as follows, express reservation being made of permissible modifications: 1. A traveling carrier hoist comprising a frame, wheels at the upper portion thereof for the support of the frame, a hook carried by the frame, a fall block adapted to be supported by said book, a cable extending to the frame and around the fall block, spring operated bumpers to release the book from the fall block whenever the carrier moves to either end of its way, means to hold the carriage at one end of the way, and means operated by the fall block to release the carriage while supporting the fall block whereby the carriage may be returned to the opposite end of the way.

2. A traveling carrier hoist comprising a rectangular frame, wheels at the upper portion of the frame for the support of the for connecting the fall block to the frame, means to hold the carriage at one end of its path of travel, means to release said carriage when the fall block is to be engaged with the carriage, and a spring operated bumper to release the fall block from the carriage when it arrives at the opposite end of its path of travel.

3. In a traveling carrier hoist, a rectangular frame, wheels at the upper portion of the frame for the support of the carrier, a pivoted hook, a fall block adapted to be supported by said hook, depending plates to guide the fall block into said hook, means to hold said carrier at one end of its way, means operated by the fall block to release the carriage to permit it to travel at the opposite end of its way, and spring operated bumpers to cooperate with means at both ends of the way to release the fall block from the carriage and to hold it in a given position until the load has been dumped.

In testimony whereof I have hereunto set my hand this 14th day of February A. D. 1916.

JOHN H. WILSON.
