UNITED STATES PATENT OFFICE.
JOHN P. DIRNER, OF HONESDALE, PENNSYLVANIA.
Specication forming part of Letters Patent No. 119,829, dated October 10, 1871.
To all whom it may concern:
Be it known that I, J oEN P. DIRNEE, of Honesdale, in the county of Vayne and State of .Pennsylvania, have invented a new and useful Machine for Dressing Railway Ties; andI do hereby declare that the following is a full, clear, and eX- f act description thereof, reference being had to the accompanying drawing forming a part of this specification.
This invention consists in a machine of novel construction, composed mainly of a system of oblique and parallel reciprocating cutters and a feeding apparatus, whereby rough logs are dressed with two iiat faces, for use as railroad ties.
In the accompanying drawing, Figure 1 is a side view of the machine, showing its frame partly broken away to expose the working parts to view. Fig. 2 is a central transverse section of the same, and Fig. 3 is a plan of a partly-dressed tie and knives and rollers.
Similar letters of reference indicate corresponding parts in all three figures.
A is the frame of the machine, which is of rectangular form, and has supported in bearings in its upper portion the driving-shaft B, one end of Which is provided with a crank, a, and the other with a pinion, b, that gears with a spur-wheel, c, on a shaft, C. This shaft C has at the middle of its length a double crank, d, which is connected by a rod, D, with the reciprocating cutterhead E, to which the lower end of said rod is pivoted by apin, f. This cutter-head is of open, boxlike construction, of a width not less than the intended thickness of the tie to be produced, and it slides vertically in guides F F, provided on the inner side of the frame A. It has secured to the forward portion of its lower edge oblique cutters G G, which cut obliquely into and chip the sides of the log, and has secured to the rear portion of the same edge parallel cutters H H that cut and trim off the previously-chipped portions of the log, and so produce flat and parallel faces. Arranged between the knives are pressure-rollers I I, whose journals have their bearin gs in a frame, J, having an upright stem, J that slides vertically within one fixed guide, g, attached to the forward one of the guides F F, and within another Xed guide, h, on the upper portion of the frame, and has formed on its upper end a stop, 7c, that comes in contact with the latter guide and prevents the ame from moving too far. Secured to the guide g is one end of a spring, K, the other end of which is secured to a pin, i, on the stem of the frame J. L L are feed-rollers arranged under the pressure-rollers on shafts lVI and N, supported in bearings in the lower portion of the frame A said wheels being geared together by a wheel, O, on a shaft, P, which is also supported in the lower portion of the frame A. At the front of the machine, in line with the feed and pressure-rollers, is a guide, j, through which the rough logs to be trimmed or dressed are fed to the said rollers, and in rear of the rollers there is a platform, Q, on which there are arranged vertical rollers It It, between which the finished ties are passed from the machine. The shaft M, on which the feed-roller L is arranged, has a ratchet-wheel, V, on one of its ends, and on each side of said wheel there is a link or plate, n, both of which are pivoted at their other ends to a rod, S, and have pivoted to thema springpawl, l. On the adjacent portion of the frame A is a stop-pawl, m, that prevents the ratchet-wheel and its shaft from turning when freed from control of its pawl l. The rod S connects the feedrollers shafts with the shaft C, and its upper end is of yoke construction for the reception of a lifting cam, T, on the end of the said shaft O. To trim or dress logs for ties they are fed through the guide J on to the feed-rollers L L', and under the pressure-rollers I I, and as the machine is set in operation by imparting rotary motion to the main shaft B the forward obliquely-arranged knives G G chip the log, as shown in Fig. 3, and parallel rear ones H H cut and trim the chipped portions oif and produce two opposite smooth faces on the log. After each stroke of the knives the cam T lifts the rod S, and by means of its pawl Z operates the ratchet-wheel V, and thereby rotates the feed-wheels so as to carry the log forward before the next stroke of the knife, and the operation is continued till the log` is dressed throughout its whole length.
What I claim as my invention, and desire tol GEO. HOFFMAN. (125)
