EDWARD EUGENE FITZGERALD, OF MILWAUKEE, IVISCONSIN, ASSIGNOR OF ONE-HALF TO THE EDWARD P. ALLIS COMPANY, OFA SAME PLACE.
LOG-CANTER.
SPECIFICATION forming part of Letters Patent No. 623,002, dated April 11, 1899.
Application filed May 24,1897.
To @ZZ whom il? may concern: i' Beil-,known that I, EDWARD EUGENE FITZ- GERALD, a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Log-Canters, of which the following is a specification.
My present invention relates to log-can ters, the operation and advantages of which will be hereinafter set forth, reference being had to the annexed drawings, wherein- Figures l, 2, and 3 are side elevations of the canter, shown in its proper relation to the log deck and' carriage, the parts being in different working positions in the various views; Fig. 4, a front elevation; Fig. 5, an enlarged sectional view showing certain details of construction; Fig. 6, a top plan view, and Fig. 7 an enlarged perspective view illustrative of certain details.
One object of my invention, among others, is to produce a canter by which the log is turned away from the 'knees in the act of turning.
A further advantage resides in the fact that by the construction employed the log as it balances over or turns over falls upon the canter-frame, which, being steam-actuated, forms, as it were, a steam-cushion for the log. By this arrangement the log does not fall upon the carriage or upon the log-deck, as is usual.
Another advantage is present in the fact that the same movement which operates the hook also turns the log, thereby saving time over those constructions wherein the log is first removed from the carriage and then turned.
Other advantages are also present and will appear in the following description.
Referring to Figs. l, 2, and 3, A denotes the carriage,and B the log deck or Way, supported upon suitable framing C. At and below the end of the log-deckv adjacent to the carriage is secured a frame D,in Whichis j ournaled a frame E in a manner to be presently explained.
Frame E has mounted within it a pistonrod F, formed with a piston G, and a cylinder H is mounted upon and works upon said Serial No. 637,927. (No model.)
ro'd, steam-inlets I and .I extending through the rod and communicating, respectively, with the upper and lower spaces above the piston. The trunnions of frame E,'working in frame D', are hollow, and the passages thus' formed connect the passages I and J with suitable steam-pipes, which are connected to the .trunnions by packed swiveled couplings.
Upon reference to Fig. 5 it will be noted that the upper and lower ends of frame E are provided with annular 'recesses K, which, in conjunction with the packing-nuts on the heads of the cylinder, form air-cushions for the cylinder at the end of its stroke as it moves up or down.
The frame E extends rearwardly, and at a point below its center there is pivoted to it at each side an arm L, which arms extend upward in a forward direction and are journaled upon the cylinder at M. To the ends of said arms is bolted or otherwise securely fastened a hook N, which extends out over the log on the carriage when the parts are-in the position indicated in Fig. 2. The rear ends of arms L are slotted, as shown, so that the point of the hook as the cylinder descends may be drawn in toward the front face of frame E. i
When operating upon logs of large diameter, it may sometimes be necessary to employ a hook of longer reach or throw, and to this end there is pivoted to the end hook N a supplemental hook N', as shown in Fig. l of the drawings. When not in use, this hook may be removed or thrown back out of the way.
The trunnions of frame E, as will be seen upon reference to Figs. 5 and 7, are formed with lugs or projections O. To each side Yof frame D are pivoted blocks P of the form shown in Figs. l, 2, 3,' and 7. These blocks are formed with a flat upper face and with a transverse opening Q, the upper side of which is cam-shaped, as shown. The lugs O of the trunnions work against these camsurfaces as the frame E is turned upon its bearings and the blocks are raised and lowered, forming a support 'for the lower face or side of the log whenv it is being withdrawn from the carriage by the hook to be turned. The blocks are so pivoted to the supporting- IOO frame D that they normally are below the log-deck and do not interfere with the passage of the logs from the deck to the carriage. (See Fig. 3.)
Beneath the log-deck and in line with the frame E are pivoted two cylinders, an oil-cylinder R and a steam-cylinder S, the cylinders being connected and pivoted in the same frame or base, as shown in Fig. 4. ton-rods of these cylinders are connected to the frame E at its rear by apin T, so that both piston-rods must move in unison.
At the base of the steam-cylinder there is provided a valve a. to control the inlet of steam to said piston, the steam passing directly from the valve into the lower part beneath the piston and through a pipe b from the valve to the upper part of the piston, according as the valve vis open to one or the otherof said inlets. The oil-cylinder is provided midway of its length with a valve c to permit the oil to pass from one end of the cylinder to the other, and thus allow the piston to' move or to stop the How of the oil, and thus stop the piston in its travel.
The 4stein d oi the steam-valve a is connected through a rocker-arm e, link f, and rocker-arm g to the oil-Valve c, the valves being arranged to open and close in unison.
To the outer end of valve-stem d there is secured another rocker-arm i, which is connected by link i to rod j, said rod being in turn connected at its forward end to a rod 7c, pivotally connected to frame E. Rodj atits rear end is connected to an arm I, secured upon a` counterweighted cross-shaft m., secured beneath the framing C. Cross-shaft m at its opposite end is connected through arm IL and link o to a slotted arm p, pivoted upon a stand q. A hand-leverris mounted in said sta-nd and in such manner that it has `a universal movement, the lower end of the lever passing through the slot in arm p and into a slot formed in an arm s, also pivoted upon the stand q. Extending from said arm S is a rod t, which controlsthe valve u, admitting steam to the upper cylinder l-I through pipes c and w.
It will be noted upon reference to Fig. 6 that the arms p and s stand at approximately right angles to each other, so that by a right line movement of the lever either one of the arms may be moved without affecting the other, While if the leverv be turned in a circular path both arms may be moved simultaneously and the machine caused to go through one complete operation. In other words, by moving the lever in a plane through the slot of one arm it will serve to operate the other arm p or s, as the case may be, or by moving the lever coincident with the surface Qf a cone, thus crossing the planes through both slots of the arms p and s, both arms will be moved simultaneously.
Assuming the parts to'be in the position indicated in Fig. 3, in which relation steam is shut off both from the lower andvupper pistons, the valve c of the oil-cylinder is closed so that no oil can pass therethrough. A log The pis-v is then rolled down the logway onto the carriage and a cut or any desired number of cuts are made. After this the operator by movement of the hand-lever fr moves arm p and through the connections above set forth admits steam to cylinder S below the piston. The valve in the oil-cylinder is also opened to the same degree as the steam-valve, an d frame E is forced upward into the position indicated -in Fig. 2. lf the lever 1' be moved in a right line only, the lower cylinder alone will be affected and the frame will be raised quickly or slowly, according to the extent to which the valves are opened. When the frame reaches its vertical position, the steam will be automatically out off through the connections i, j, 7o, and with shaft m, but not until the parts have passed from the position indicated in Fig. 3 to that indicated in Fig. t3. While the frame is moving into the vertical, the operator by a further movement of the leverin a line, so as to act upon arln s, admits steam into cylinderH, causing the hook to descend and enter the log, when by a further movement of lever r in a circular path steam lwill be admitted in the upper end of cylinder S and the frame drawn down. In turning, lugs O, acting upon block P, will throw said blocks upwardly into the position denoted in Fig. l, thereby forminga support for the lower side of the log. As the log is turned away from the carriage and knees it rests bodily against the frame and upon the block vandthe descent of the frame and cylinder is elevating cylinder H and hook N into positionto again operate upon the log.
Through the-connections of the valves and the controlling-lever, as above set forth, the movements of the machine are in a sense i11- dependent of the movement of the lever after the machine has once been started-that is to say, the frame will move entirely up or down unless arrested and then automatically come to a stop, the valve being what is known as a floating valve.
If it be desired to move the frame quickly, all that is necessary is to give the lever a full throw, opening the steam-valves to their full extent and also opening the oil-check valve to a like degree, thereby permitting the steam to act with its full force and effect. Ordinarily, however, steam is admitted gradually, and the piston in the lower cylinder can move only as fast as the oil in the oil-cylinder can pass from one side to the other, and when the machine comes to a lstop the steam is pre- IOO IIO
vented from working expansively by the oi-lcheck.
As before stated, one complete revolution of the controlling-lever will cause the frame to ascend to the vertical, the hook to engage the log, the frame to swing back, carrying the log with it, the log to be turned and placed at face down upon. the carriage, and finally the hook to ascend ready to again engage the log.
Ey shifting the pivotal connection of link t along the link j the point at which the valves will close can be regulated as desired.
W'hen the log is iirst rolled upon Vthe carriage and the frame is in a horizontal position, the Vlog may, if necessary, be Vcrowded up against the knee by simply admitting steam above piston G, causing the hook to press the log forward, thereby answering the purposes of a log-loader.
