CABLE-FEED WORKS.
SPECIFICATION forming part of Letters Patent No. 457,415, dated August 11, 1891. Application led February 20, 1891. Serial No. 382,252. (No model.)
' of this specification.
The main objects of my invention are to secure a greater iiexibility for a given. tensile strength of cable, and thereby to admit of the use of a smaller drum and an engine of less power for the performance of the required work and to distribute the load or pull equally upon the bearings of the drum.
It consists, essentially', of a driving-drum, a sheave located at or near one end of the travel of the carriage, and a double cable attached at the ends to said carriage, both strands of the cable passing around said drum in the same direction, thence over said sheave to the carriage, and of certain other peculiarities of construction and arrangement hereinafter specified.
In the accompanying drawings like letters designate the same parts in the several ligures. fr
Figure l represents a side elevation of the apparatus applied to a saw-mill carriage. Fig. 2 is a plan'view of the feed-works, and Fig. 3 a detail showing a modification of the device for attaching the cable to the ends of the carriage.
A represents a saw-millY or other reciproeating carriage, for the operation of which my improved feed-Works is specially designed.
B represents the drum, which in the present instance is located at or near one end of the travel of the carriage and takes the place of the eXtra sheave which is required when the driving-drum is located at an intermediate point in the travel of the carriage. It is formed on the periphery with right and. left grooves, each occupying approximately onehalf of the cylindrical face of the drum, as shown in Fig. 2. The drum Bis supported in the usual manner in bearings b b, preferably located at equal distances from either side thereof, so as to sustain equally the load or pull through the cable upon the drum.
C represents a sheave or pulley located at or near the other end of the travel of the carriage, and formed at its periphery with two grooves, as shown in Fig. 2.
D represents the cable, which is doubled,
one section being wound-around one groove A in the drum B and the other section being wound 1n the same direction around the other groove, the two sections passing from the un- .der side of the drum around the sheave C, and thence to the carriage, to which they are attached.
To distribute the pull or load equally on 4both sections or strands of the cable D, I prefer to attach it to the carriage by means of is'mall sheaves d d, which may be secured, as shown, to cross-pieces a a, at or near the mid.-
dle of the carriage, or to the cross-pieces at the ends of' the carriage-frame. These sheaves d CZ' are preferably provided with threaded bolts or rods d ,by which they are adj ustably secured in the cross-pieces of the carriageframe, so as to afford means for taking up slack in the cable. By means of the nuts cl2 on the inner ends of the rods d" the sheaves d d are drawn toward each other in the direction of the travel of the carriage, and the cable is thereby tightened. In place of the sheaves d d levers e, fulcrumed at the center to screw-threaded rods e', adj ustably attached to the cross-pieces of the carriage-frame in the manner specified, may be employed, as
shown in Fig. 3, the cable in this case being severed and secured to the ends of the levers e e equidistant from their fulcrums.
The cable, as shown in Figs. l and 2, may be continuous and unbroken, or it may be severed and the ends attached at the proper IOO being obviously greater than a larger one on the cable.
By employing a two-strand or double cable I am enabled to distribute the pull or load equally upon the bearings of the drum at all times in the manner previously described. This is a marked advantage in the operation of the apparatus, inasmuch as unequal Wear of the bearings of the drum is avoided and the true and easy Working of the drum is insured.
Various modifications in the details fof the apparatus maybe made within the spirit of my invention.
I claiml. In cable-feed works, the combination, with a reciprocating carriage, of a drivingdrum formed with righ-t and left grooves in its periphery, a double cable having a selfadjusting 'connection atthe ends with the carriage, by which the load is equally distributed through both strands of the cable, one strand of said cable passing around one groove and the other around the other groove of said drum, and 'a sheave 'over which both strands of the cable pass, located at or near one end of the travel of the carriage, substantially as and for the purposes set forth.
2. In a cable-feed works, the combination of a reciprocating carriage provided With sheaves, a driving-drum provided with right and left grooves on its periphery, a sheave located at or near one end of vthe travel of thev carriage, and a double cable passing around the sheaves on said carriage, both strand-s passing thence around `said sheave, thencek around the driving-drum, one strand in one groove and the other in the othjer groove of said drum, substantially as and for the purposes set forth.
3. In cable-feed Works, the combination of a reciprocating carriage provided with sheaves adj ustably secured thereto, a guiding-sheave located at or near one end of the travel ofthe carriage,a driving-drum formed in its periphery with right and left grooves, and a double cable passing around the sheaves on said carriage, thence around the Vguiding-sheave, and thence around said drum, substantially as and for the purposes set forth.
-4i. In cable-feed works, the combination of a reciprocating carriage, a sheave located at or near one end of the travel of said lcarriage, a driving-drum,'an'd a double 4cable 'attached to said carriage at the ends, both strands passing 'over said 'sheave and around said `drum .in the same direction, substantially as and for the purposes set forth.
5. Ina cable-feed Works, the combination, With a reciprocating carriage, of a drivingdrum, a sheave located at or near one limit of the travel of the carriage, and a `double cable having an equalizing connection with the carriage, by which the pull is equally distributed through both sections of the cable, which pass over said sheave and thence around the drum,substantially as and for the purposes set forth.
In testimony that I vclaim the foregoing as my own I affix lnysignature in presence of two Witnesses. l
