iliTE Tiaras FFIGF? PATENT CHARLES H. LA DUE, OF NEW YORK, N. Y., A SSIGNOR TO THE LA DUE MECHANICAL MOVEMENTOOMPANY, OF NEYV YORIQ' MECHANICAL MOVEMENT.
SPECIFICATION forming partof Letters Patent. No. 307,859, dated November 11, 188
Application filedApril 26, 1884. (No model.)
To all whom it may concern.-
Be it known that 1, CHARLES H. LA DUE,-
of the city, county, and State of New York, have invented a new and Improved Mechanical Movement, of which the following is a full, clear, and exact description.
The object of this invention is to convert reciprocating motion into rotary motion without theuse of a crank; and the invention-con sists, principally, in forming in any suitable device attached to the shaft an eccentric groove or slot, in which a stud or its equivalent secured to the connecting or piston rod works, so that the thrust of the piston will act against the curved surface of the groove, and thus cause the wheel to revolve. The device is likewise applicable to mechanism in which the power is derived from a revolving crank, whereby, through the instrumentality of my invention, a properly-supported bar may be given a rectilinear reciprocating motion adapted to operate 7 a punch, a pump-rod, or similar device.
The invention also consists in supporting and guiding the free end of the piston-rod or the connecting-rod on the shaft rotated by it. This may be done by extending the shaft past the wheel, and in forming the piston-rod or connecting-rod with a slot or other suitable guiding and supporting surface with which the shaft engages, so that the-shaft acts as a guide to the movement of the piston-rod or the connecting-rod, as the case may be; or the support for the rod may be at any other part of the shaft.
Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.
Figure 1 is a side elevation of a steam-locomotive, showing my invention applied thereto. Fig. 2 is a detailed plan view in section on the the line a: m, Fig. 1; and Fig. 3 is a detailed sectional plan view showing a modification.
A A represent two of the drive-wheels of the locomotive; B B, the axles, which reach past the drive-wheels A when it is desired to use them as guides or ways for the piston-rod; and 0 represents one of the piston-rods, which is reciprocated by steam entering the steam-cylinder D, in the ordinary way. The drive-wheels A have formed in them eccentric to the axles B thegrooves or slots a, which describe a circle the diameter of which is equal to the length of the piston-stroke, and in these grooves or slot-s work the rollers b, journaled upon the studs 0, secured to the connecting-rod O. The connectingrod O is preferably formed with the slots (1, through which the protruding ends of the axles B pass, as shown clearly in Fig. 2,
so that the axles serve as guides to the reciprocating movement of the connecting-rod'O, and to avoid the dead-centers the drive-wheels upon the opposite side of the locomotive from that shown in the drawings will be arranged upon the axles with the eccentric grooves therein one-quarter of a turn ahead or one-quarter in rear of the'grooves in the wheel A A. The free end of the piston-rods may be supported and guided by the ordinary ways, or in any other desired manner; but I prefer to slot the pistonrod and allow lateral projection of the axles B for this purpose, as stated; and instead of the piston-rod being slotted, it may be supported in any other suitable manner on the shaft--as, for instance, by a guide or way block mounted on a sleeve, which embraces theshaft, but does not turn with it, and such sleeve or other equivalent device'may engage with the shaft at some other point than on a projecting end thereof. By the arrangement described it will be seen that the connectingrods 0 are but extensions of the piston-rods O, and that they reciprocate in a direct line, and that the studs 0, working in the eccentric grooves a, cause the wheels to revolve without the employment of cranks. The eccentric grooves or slots a may be a plain groove or slot with straight sides; but I prefer to form it with inclined sides, as shown in Figs. -2 and 3, in which case the rollers 12 will be made coneshaped to fit the grooves, and these coneshaped rollers will be made adjustable in the connecting-rod O, to take up any wear of the groove or roller; and I design in some cases to form the eccentric a by means of separate castings f f, secured concentric to each other to the face of the wheels by means of bolts or rivets, as shown clearly in Fig. 3, or in any other desired manner, so that my invention may be applied to wheels already in use.
A pin rigidly attached to the end of the piston-rod with conical end may be employed instead of the conical roller; but I prefer the roller for the sake of reducing friction.-
Although I have shown my invention applied to a steam-locomotive, it will be understood that it may be applied to shafts and wheels generally where a reciprocating is to be converted into a rotary motion;- and I wish it also to be understood that my invention is applicable to such structures as punches, pumprods, and the like, in which substantially the same mechanical principles are involved, but with the difierence that in such structures the power will emanate from the shaft, it being caused to rotate by any suitable means, and that then the punch rod or plunger or the pump-rod, as the case may be, being suitably supported and guided in anysuitable manner-- as, for instance, by ways-will move in rectilinear lines and with a reciprocating motion.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. The groove a, having inclined edges, ,in combination with the connecting-rod having the adjustable cone-shaped roller 1), substantially as and-for the purposes set forth.
2. The eccentric groove a, formed by the separate castings f, secured to the wheel, substantially as and for the purposes set forth.
3. The axle B, reaching past the wheels A, in combination with the connecting-rod 0, provided with slots d and studs 0, which latter work in the eccentric grooves a, formed in the wheels A, substantially-as and for the purposes set forth. 7 4. A rotatable shaft extending beyond the journals which support it, in combination with a reciprocating rod or bar supported and guided by the projecting end of the rotatable shaft, substantially as and for the purpose set forth.
5. The combination of a reciprocating bar or rod, a revolvable shaft, and means where- 5 by the reciprocating bar or rod is supported and guided by the shaft, substantially as and for the purposes set forth.
