MACHINE FOR CUTTING RAlLWAY-TlES.
SPECIFICATION forming part of Letters 2 atent No. 641,202, dated January 9, 1900.
Application filed October 21, 1 899. Serial No. 734,385 0 model.)
To ail whom it may concern;
Beit known that L'CHARLES W. GA n ANn,a citizen of the United States, residing at Bluefield,in the county of Mercerand State of West Virginia, haveinvented certain new and userotary beveled cutting-blades set at suitable angles, means being provided to automatically engage the dog with the logs as they are passed through the feeding-trough to the cut-,
ters, and in the provision of additional means for holding the log in the trough while its sides are being hewed or ent to form the sides of. th e finished tie.
More specifically the invention resides in the provision ofshafts having cutting-blades disposed at an angle on the beveled surfaces of the rotary cutter-heads disposed in reverse positions to each other and an endless chain carrying dogs, the spurs of which are caused to be forced into the end of a login the feeding-trough by means of a pivoted pressureihammer, the free end of which rests against a leg while being cut-,and after the log passes by thecuttenheads said pressure-bar adapted to swing down under the influence of a spring or by gravity and coming in contact with the followin log to impart a longitudinal move ment to the latter suilioient to cause the spurs of the dog t:- engage in the log, the pressurebar after having kicked against the end of the log adapted to ride over the latter as the log advances. toward the rotary -cutter-heads.
To these ends and to such others as theinvention may pertain the same consists, further, inthe novel construction. combination, and arrangement-of panda-as will be more i ully described and claimed.
'My invention is'clearlyillustrated the accompanying drawings, whiclnwith the let ters of reference marked thereon, form part of this specificatiomand in which drawings similar letters of reference indicate like part-s 1 throughout the several views, in whichtie-cutting machine. Fig. 2 is a top plan view. Fig. 3 is a horizontal sectional view through the machine, and Fig. 4 is a detail view.
Reference now being had to the details of the drawings by letter, A'designates .a suitable framework, on which is mounted operat-ing-shafts B, to-which are keyed the two I Figure l is a side elevation of my improved bevel-faced cutter-heads C. These cutter: V
heads have slots 0 through their beveled sur faces, which slots are disposed at an angle less than a right angle to the outer fiat ends. of the cutter-heads, and in each of these slots a knife D is designed to be held in any suitable manner as in ordinary bench-planes. Located in the frame is the feeding-trough E,
' which runs longitudinally of the frame and between the cutter-heads. Mounted on the shaftsh, near the ends; of the frame, are,
sprocket wheels G, over which an. endless chain H travels. This chain has one or more dogs K formed out of links of the chain, or said dogs may form distinct plates, which are pivoted to the endless chain, and each dog has an upward projection K", the vertical edge of which has a series of teethL, designed to engage with-the end of a log and feed it forward to the cutterdiead; Mounted adjacent to the rotarycutter-heads, slightly in advance of the same, are the standards M, to the n pper ends of which isjournaled fa stub-shaft N, 'havin'g'keyed thereto the pressure-berth;-
Said pressure-bar has a laterally-extending arm R, to the outer end of which is connected a rod or chain S, the lower end of which is connected to a spring-bard, one end of which is securedto the frame of the machinc,e stii".
The operation of my device will be readily understood when considered in connection with the drawings and the foregoing description and is as follows, viz: The logs are first placed upon the endless chain and are fed forward by means oftthc dogs catching in, the
rear end of eachlog, and when thefornlard end of a log strikes the pressure ba-r Q the free end of said pressure-bar is thrown up and the said bar rides on the. upper surface of the log, serving to hold the same securely in place 'inthefeeding-trough as said log is fed forward by the endless chain carryiii gthe dog. After one log has passed between the rotary beveled cutters and is held securely in place in the feedingtrough during the-cutthat as the pressure-bar having held one log while it is being out will fly down and kick against the fo1lowing log, which will 'cause a slight longitudinal movement to be imparted to the same sufficient itodrive the teeth L of the dog into the end of. the log to securely hold the same as the log is being fed-forward.
As the log which has been kicked by the pressure-bar to engage the spurs advances toward the cutter-knives the pressure-bar will be pushed-out of the path of the advancing log and serve to press on the upper surface of the log and seeu'relyhol'dit while therotarycutters are beveling the opposite faces of the. tie. It will be noted that the knives are set at such angles that a draw cutis afforded on the surface being hewed, as the heads carryingthe knives are caused torotate as the log is being fed forward. Havingthus described inyinvention, what I claim to be new, and. desire'to secure by Lettens Paten t, is-
11. In combination in a machine for cutting railway-ties, the frame, the beveled cutters, the shafts carrying the same, the cuttingknives seated in apertures in the beveled faces of saidycutters, the feeding-trough, the end less chain and dogs carried thereby, the piving arm, a spring secured to said arm, said bar being disposed-fin the path of the advancing log, adapted to'hold the latter in posit-ionwhile being' eut and to kick against the end of the following log to engage the rear *the end of afollowing log whereby the latter is driven against the teeth of the dog engaging the end of saidfollowing log, as and for the purpose set forth. 1
In testimony whereof 'I allinniy signature inpresence of two witnesses.
