UNITED STATES PATENT OFFICE.

THOMAS SPENCER MILLER, OF SOUTH ORANGE, NEW JERSEY, AND JOSEPH H. DICKINSON, OF ATLANTA, GEORGIA.

Specification of Letters Patent.

Patented Feb. 11 1908.

Application filed October 18. 1902. Serial No. 127-788.

T 0 all whom it may concern:

Be it known that we, THOMAS SPENCER MILLER, a citizen of the United States, and a resident of South Orange, county of Essex, and State of New Jersey, and JosEPH H. DIOK- INSON, a citizen of the United States, and a resident of Atlanta, Fulton county, State of Georgia, have invented a new and useful Improvement in Hoisting and Conveying Apparatus,'of which the following is a specification.

Figure 1 is a side view of one form of our invention adapted for a cableway. Fig. 2 is' a detail of the load-carriage drum or sheave for the same. Fig. 3 is a side view of another form of our invention adapted for a cable- Way. Fig. 4 is a detail of the load-carriage drum or sheave for the same. Fig. 5 is a side view of another form of apparatus containing our invention. Fig. 6 is a detail of the loadcarriage drum or sheave of the same. Fig. 7 is a side view of a form of our invention adapted for a logging apparatus. Fig. 8 is a detail of the load carriage drum or sheave for the same.

In all of said figures, the head-support is at A, the tail-support at B.

O is the cable or trackway.

D is the load-carriage.

E is the friction operated hoisting-ropedrum of the engine. a is the hoisting rope operated thereby.

c is the fall-rope which, in one form, is in-' tegral with the hoisting rope e, and in other forms separate therefrom.

F is the friction slack-pulling-rope-drum of the engine.

f is the slack-pulling-rope which in one form is integral with the hoisting rope and in other forms is separate therefrom.

G is the friction traction-ropedrum of the engine.

g is the traction-rope operated thereby which is shown as substantially endless, hav ing both ends fast to the load carriage.

1, 2, 3 and 4 are guide sheaves on the head-support. 5 and 6 are guide-sheaves on the tail support. 7 and 8, the load-carriage wheels running on the cable or trackway. H, the load-carriage drum or sheave composed of a plurality of parts h, 72/ or h, 7L2, h.

In all the forms of construction shown, the hoisting rope e and the slack-pulling-rope f extend from the carriage to the head-support and thence to their respective drums at the engine. At the load carriage, they respectively engage, directly or indirectly, with the load-carriage-drum or sheave II in such a manner that when hauled in they tend to turn said drum or sheave H in opposite directions. The relative surface speed'of the engine drums E and F is substantially equal, in

case the outer ends of the ropes e and f are both fastened to said drum or sheave H; but if either or both of said ropes c or f form a wrapping engagement with said drum or sheave H, the engine will be so proportioned that the surface speed of the engine drum F will be slightly faster than that of the enginedrum E to insure against any slack occurring in said rope e by reason of any slipping of said wrapped connection.

In the construction shown in Fig. 1, the load-carriage sheave or drum H is in three parts, h, h and 72, The traction-rope g is substantially an endless rope fastened to the frame of the load-carriage D so as to be adapted to hold it in any position or move it in either direction. The fall rope c has its upper end fast to the middle drum part h upon which it is coiled. Thehoisting-rope e is fast at one end to the engine-drum E, and at the other end to one of the drum parts 7?. The slack-pulling-rope f is fast at one end to the drum-engine F and at the other end to an end drum part 7L2.

In the form shown in Figs. 3 and 4, the traction rope is the same as before, but the hoisting-rope e, and the fall rope c are integral with each other, or one continuous rope, which makes a sufiicient number of wraps around the drum portion h to avoid slipping thereon. The slack-pulling-rope f is ,as before, secured at one end to its enginedrum F and at the other end to the drum portion 72. The drum H consists of only two parts.

In the form shown in Figs. 5 and 6, the traction rope is, as before; but the hoistingrope e and slack-pulling-rope f are integral with each other constituting a single continuous rope fast at one end to the enginedrum E and at the other end to engine drum F and making a sufficient number of turns around drum part h to prevent slipping thereon. The fall-rope e is separate and made fast to the drum part h In this form, also, the drum H consists of only two parts.

The construction shown in Figs. 7 and 8 is substantially like that of Figs. 1 and 2, so

far as concerns the drum H, and its connec tion with the hoisting-rope e, slack-pullingrope f and fallrope e. The traction-rope however, is fast at one end to the enginedrum G and extends thence over the head sheave 2 between the guide-sheaves 9 and 10 on the carriage D, between the guide-sheaves 11 and 12 on the supplemental carriage D, around the tail-sheave 5, and is made fast to the supplemental carriage D. A substan tial continuation g of the traction-rope g connects the carriages D, D. The carriage D is provided with the wheels 13 and 14 running on the cable or trackway O. A guidesheave 15 is pendent from the frame of carrier D and over this sheave the fall-rope e is led from the drum H so as to facilitate the handling of logs by the tongs 16 at the lower end of the fall-rope e.

Although we have shown the several p arts of the drum H as co-axial and as rigidly se cured together, we do not limit ourselves to this form of connection or location. We Will employ the term, drum members, to include broadly all variations of connection and relative position of the three drum parts.

In operating the constructions shown in Figs. 1, 3 and 5, as the traction-rope g moves the carriage toward the tail support, the ropes c and f are paid out in unison; and as it is moved toward the head-support, the ropes e and f are hauled in in unison. The fall may be lowered by holding the tractionrope stationary and hauling in on the slackpulling-rope f, and paying out correspondingly the hoisting rope c. The load may be hoisted by holding the traction-rope stationary, hauling in on the hoisting-rope c and paying out on the slack-pulling-rope Substantially the same mode of operation exists in Fig. 7 excepting that the construction therein shown being for logging purposes, no

endless ropes are employed; the return run of the traction-rope from the load-carriage to the engine being omitted and the hauling in of the ropes e and f in unison being depended upon for moving the load-carriage toward the head Having thus fully described our invention,

we claim as new and desire to secure by Letters Patent:

1. In a conveying apparatus, in combination, a trackway, a traveling carriage thereon, an outhaul traction rope having its outer free end connected to the frame of the carriage, a plurality of traveling drum parts connected in axial alinement, two stationary drums, a rope connecting each of said stationary drums with one of said traveling drum parts to operate inversely, and a rope operated by one of said traveling drum parts for connection with an object to be hauled.

2. In a conveying apparatus, in combination, a trackway, a load carriage, an outhaul traction rope having its outer free end connected to the frame of the carriage, a drum containing a plurality of connected parts on said carriage, a fall rope from said drum, hoisting and slack pulling ropes extending respectively from the top and bottom of said drum toward the end of the trackway.

3. In combination a traveling carriage em- -bracing a triplex traveling drum, an outhaul traction rope having its outer free end connected to the frame of the carriage, a rope 1 for connecting the middle part thereof with the object to be moved, two stationary drums, and ropes connecting them with the outer parts respectively of said traveling drum. I

4,. In combination, a triplex traveling drum, three stationary drums, ropes connecting two of them respectively with the outer parts of said traveling drum, a rope connecting the third drum with the frame of said traveling drum, and a rope connecting the middle part of said traveling drum with the object to be moved.

In testimony whereof we have hereunto signed our names to this specification in the presence of two subscribing witnesses.
