EBENEZER WOODBUBY GERRISH, OF JACKSONVILLE, FLORIDA.
LOG HAULING AND LOADING MACHINE.
Specification of Letters Patent.
Patented Sept. 1, 1908.
Application filed February 24:, 1905. Serial No. 247,205.
To all whom it may concern:
Be it known that I, EBENEZER WOODBURY GERRISH, a citizen of the United States, and a resident of Jacksonville, Duval county, and State of Florida, have invented a new and useful Improvement in Log Hauling and Loading Machines, of which the following is a specification.
In practice, I have applied my invention to a log hauling and loading machine of the general character described in Patent No. 726325 dated April 28, 1903, to Thomas Spencer Miller and Joseph H. Dickinson.
In the accompanying drawings, Figure 1 is a side view of a machine embodying my invention. Fig. 2 is a plan view of the same minus the upper structure. Figs. 3 and 4 are details. Fig. 5 is a detail view showing the drum for operating the suspender.
A is a platform or frameof any suitable construction which will give sufIicient space and strength to hold the machine and to be carried when in use by supports at each side of the track sufficiently separated to permit the passage of cars between them. Upon this platform is mounted the hoisting or hauling engine necessary to work the required lines and a boiler or boilers to furnish steam for them, as well as the mast and boom. Longitudinal sills a are placed beneath each side of the platform and to each of these are secured blocks a at each end of the platform. B are beams resting on the ends of the ties outside of the rails C.
b are blocks interposed between each of the beams B and the two blocks a above it.
D are hydraulic jacks each interposed between a sill a and a block E resting on a beam B. The construction of each of these jacks is shown in Fig. 4. The upper part consists of a cylinder d and the lower partof a plunger (1. The cylinder is supplied with water from the water barrel F by the pump G through the piping shown. Connected with this system of piping is a relief valve H set to relieve all pressure beyond a certain point.
I is a safety vent in the cylinder to permit the escape of the water when the plunger has been forced downward beyond a given point.
J is a suspender for the lower plunger portion d of the jack, which suspender is coiled upon a drum operated by the handle j and held in any desired position by the ratchet j and pawl j. The supply piping to each jack is provided with a threc-way-valve K and a cut-off-valve L.
The machine operates as follows: The platform A is brought to any desired position when loaded upon an ordinary car. The beams B, blocks E and jacks D are then laced in position and the platform is raised off of the car by the operation of the acks. This enables the blocks l) to be placed under the blocks a. Then the jacks are operated to permit the lowering of the blocks a onto the blocks 1). After this lowering, however, the platform A. is still high enough to permit the passage of cars beneath.
In. the operation of the jacks for raising, the three-way-valve K'is set so as to cut oil the discharge of water and permit its passage through the piping, and the valve L is opened. I/Vhen the hydraulic jacks are operated for lowering, the three-wayvalve K is turned so as to discharge the water from the piping through the escape 7c and the cutoff-valve L is closed.
When the machine is loaded upon a car for transportation, the cylinder or upper portion (Z of the jack will he held to the sill a by being bolted permanently thereto as by the belts d. The plunger portion of the jack will be held in position by the suspender J, VlllCll sus)ender, of course, is released while the jaclr is being hydraulically operated.
Having thus described my invention, what I claim as new is,
In a log hauling machine, in combination, the engine-supporting-platform, legs therefor adapted to straddle the railway track, hydraulic jacks cooperating with said legs and a pump mounted upon said platform whereby said jacks are operated, and a sus' ponder wliereby the lower member of each of said jacks is suspended when not in operation.
In testimony whereof, I have hereunto signed my name in the presence of two subscribing witnesses.
