SPECIFICATION forming part of Letters Patent No. 286,225,
dated October 9, 188.
A pplicaiion filed March 15, lSr-i. tNo model.)
1'?) (L whom, it may concern..-
Be it known that I, Funnels l-l. l'tronums, a citizen of the United States, rcsidin at (leveland, in the county of Ouyahoga and State of Ohio, have invented certain new and useful Improvements in Mechanism for Converting Motion, of which the following is a specification.
My invention relates to that class of devices in which continuous rotary motion is converted into intermittent rotary motion and into longitudinal reciprocating motion, both of the said resultant motions being communicated to the same element of the device. The mechanism by which I accomplish this result is shown in the drawings by three general views, drawn in projection, the better to illustrate the nature and present construction of the parts, in which Figure 1 is a front elevation of the entire mechanism. Fig. 2 is a side elevation with a portion of the frame removed, and Fig. 3 is a plan view with the upper part of the frame removed. Fig. i is an enlarged view of a portion of Fig.
Similarletters refer to similiar parts throughout the several views.
The frame by which the operative parts are supported is composed, in the present instance, of the base 13, two uprights, A A, and top T. Upon one side of the uprights A A are bearings c, which support the driving-shaft D.
, Upon their opposite sides are bearings e, whichsupport rocker-shaft It, and in the base B and top T are suitable holes to form bearings for the intcrmittently-rotated shaft S.
The driving-shaft D is designed to receive continuous rotary motion from a band upon pulley D, and carries a lifting-cam, L, and the rotating cam composed of the two parts Gand 0/. This rotating cam has, between the two sections thereof, a channel, a 1;, extending around it through somewhat more than three hundred and sixty degrees, within which suitably-formed arms a on shaft S are adapted to move. This channel a ois so formed and proportioned, and the arms a so disposed about and upon shaft S, that when, by turning the cam C over toward the front, the arm a (see Fig. 3) arrives at o the arm a" will have just entered at a, and upon continuing the rotation of cam C the arm a" will, at the next turn, pass out at '17 and arm a enter at'u, similiarly as before, and so on indefinitely.
It will be obvious, upon considering the an rangement and operation of the parts hcrcin before described, that the velocity of the rotation of shaft S relative to that of shaft D, and also the length of the interval of rotation of shalt S, and of the interval, if any, of rest of said shaft S, depend upon the conformation of the channel a r, which therefore should be constructed agreeably to the number and length of arms a and the desired relative proportions of the said intervals of rotation and rest of shaft S. In the present instance, as best seen in Figs. 3 and 2, the interval of rotation of shaft S is approximately one-fourth and the interval of rest the remaining three-fourths of a revolution of driving-shaft D.
In orderto avoid the friction and consequent wear to which the end of arms a would otherwise be subjected, and also to secure the most exact regulation of the rotation of shaft S, the said arms are each provided with two rollers, H1, (see Fig. 4,) of which 71. rolls against the side of channel a '0, formed on part 0, and the other of which, '1 rolls against the opposite side of the said channel. formed on part 0 of the rotating cam. By turning either of the parts 0 C in the proper direction upon shaft D, or by sliding them longitudinally thereon, or both, either the circular or spiral portions of the channel a 1) may be so adjusted as to take up any play resulting from wear or otherwise, and thereby cause the rollers ilP to revolve therein as closely as may be required.
The cam L imparts longitudinal rcciprocat ing motion to shaft S, in the present instance vertically, by means of lever (l, rocker-shaft R, and arms j, provided with pins working in groove b, Fig. 2, of shaft S. The operation of these parts to producethe said motion will be apparent without further particular descri pti on.
. In the present instance I have shown and described the rollers. 2' h located with their axes in a line and between the faces of parts 0 G,
forming the channel av,- but by a slight change of construction the position of the canrfaces can be reversed and the cam take the form of 10) a rib between the two rollers. This latter form of construction, while it is operative, I consider less desirable than the form shown, but I two rollers operating against separate faces 20 as included, nevertheless, in my claims. In the present instance, also, I have shown the channel a 42 extending entirely around the cam C; but it is obvious that two, three, or more such channels may be formed successively in one cam to operate in the manner described.
I claim as my invention- 1.. In combination, the shaft S, having a regular series of arms, a, and the cam 0, constructed to receive and part from said arms a successively, substantially as described.
2. A series of arms, a, adapted to be rotated-about a common axis, in combination with the canrO, formed in two parts, adjustably secured,'substantially as and for the purpose described.
3. A series of arms, (1, arranged equidistant in a plane around shaft S, each provided with of said cam O.
4. A series of arms, a, adapted to be rotated about a common axis, and each provided. with two rollers having axes at or nearly in a line, in combination with the cam 0, having the channel a c, all arranged to operate in the manner. substantially as described.
5. The shaft S, provided with a series of arms, a, and cam 0, having channel a o, in combination with cam L and mechanism for imparting motion therefrom to shaft S longitudinally, all arranged to operate substantially as set forth.
