STEAM-POWER CROSSCUT-SAW.
SPECIFICATION forming part of-Letters Patent No. 503,665, dated August 22, 1893.
Applicationrled August 13, 1892. Serial No. 4413.049.V (No model.)V
To @ZZ whom it may concern:
Be it known that I, JOHN B. KELLY, a citizen of the United States, residing at Pleasant Home, in the county of Multnomah and State of Oregon, have invented a new and useful Steam-Power Crosscut- Saw, of which the following is a specification.
My invention relates to improvements in cross-cut saws in which steam-power is ernployed for the operation thereof.
The objects and advantages of my invention will appear hereinafter in the description, and the novel features thereof Vwill be particularly pointed out in the claims.
In the drawings: Figure 1 is a perspective view of a saw embodying my improvements, arranged in operative position. Fig. 2 is a side view, showing the opposite side from that shown in the perspective. Fig. 3 is a detail Fig. 4 is a longitudinal sectional View of the cylinder. Fig. 5 is a detail view of the piston and attaching arm with the flexible strap shown in connection therewith. Fig. 6 is a detail view of one of the cams for operating the valve -stem. Fig. 7 is a similar view of the rock-shaft and crank. Fig. 8 is a detail view of the pin with removable head detachedA l The supporting-frame 1 comprises, essentially, the pivoted arm v2, to which is ful crumed the dog 3, the cylinder to which said arm is pivotally connected being indicated at 4. In the rear end of said cylinder, in a bearing 5, is mounted a rock-shaft 6, carrying a crank 7, upon the lateral arm of which is fulcrumed the rear end of the supporting arm. Said arm is trussed and is provided at the center of the truss 8 with a spindle 9, upon which is fulcrumed a cross-bar 10. The bifurcated inner end of the shank 11, of the dog 3, is pivotally connected to the ends of the said cross-bar, whereby said dog is capa ble of any desired angular adjustment to suit the shape and size of the timber to which the saw is applied. The supporting-arm is further provided, at an intermediate point in advance of the pivoted dog with a segmental guide 12, which operates in a clip 13, attached to the front end of the cylinder, whereby the front end of the latter is capable of elevation` and depression with relation to the supporting arm to allow of the necessary adjustment of the saw carried by the cylinder, as hereinafter explained. At the upper end of the segmental guide is mounted a transverse windlass shaft 14, carrying asuitableoperatngwheell and provided with a pulley 16 and a spool 17. A cable 18, which is attached permanently at its lower end to a pin 19 at the front end of the cylinder, is reeled upon the said spool. A pulley 2O is mounted upon the supporting arm below the pulley carried by the windlass and around the said pulleys passes an endless belt 22, which is attached at anintermediate point to a stationary pin 23, carried by the cylinder, whereby by the operation of the Windlass the elevation or depression of the front end of the cylinder may be regulated. The supporting arm is further provided at its front end with a series of perforations 24, adapted to receive a securing-spike 25, to be driven into the log which is to be sawed.
Attached to the free end of the crank-arm above described, which is fulcrumed to the rear end of the cylinder, is a guide-pin 26, operating in a guide-eye 27, carried by the cylinder and provided with a tension-spring 28, held in place by an adjusting-nut29, whereby the end of the crank-arm is normally held close to or in the plane of the upper side of the cylinder. Y,
30 represents the steam supply pipe communicating at its ends with the slide-valves 31, which in turn communicate with the ends of the cylinder. The valves are connected by the stem 32, providedwith keepers 33, pivoted angle-leverst being oppositely disposed upon the cylinder `and having their upper arms engaged in said keepers, and their lower arms, which project, respectively, toward the front and rear ends of the cylinder, arranged below the plane of the lower side of the latter.
35 represents the saw carried by the sliding saw-head 36, the latter being provided at its opposite ends with cams 38, to engage the lower ends of the angle-levers alternately. Said cams are in the shape of oppositely-inclined webs, carried by plates 39,'which are longitudinally slotted, as seen at 40, said slots being engaged by adjusting bolts 41, Whereby the cams may be adjusted toward or from ICC each other to lengthen or shorten the length 4. The combination with the cylinder and the steam-actuated saw-head mounted upon said cylinder, of the rock-shaft mounted in a bearing at one end of the cylinder and provided with a crank-arm, the supporting frame fulcrumed upon said crank-arm, and the segmental guide carried by the supporting-frame and engaging the front end of the cylinder, and carrying means to adjust the cylinder with relation to the supporting-frame, substantially as specified.
5. The combination with the cylinder and steam-actuated saw-head, of the supportingframe, the rock-shaft mounted in a bearing at the rear end of the cylinder and carrying a crank-arm, a guide-pin connected to said crank-arm and operating in a guide-eye on the cylinder and provided with a spring, the se?,- mental guide carried bysaid supporting-frame and operating in a guide upon the front end of the cylinder, and a Windlass carrying an endless belt which is connected with the cylinder, substantially as specified.
6. The combination with the cylinder and steam-actuated saw-head, of the rock-shaft mounted upon said cylinder and carrying a crank-arm, the free end of which is connected to the cylinder by a spring-actuated guide-pin,
the supporting-arm connected to the free end .and guide-roller attached to the front end of the cylinder to guide and receive the upward thrust of the saw, substantially as specified.
In testimony that I claim the foregoing as my own I have hereto aitxed my signature in the presence of two witnesses.
Y JOHN B. KELLY.
