IMPROVEMENT IN MECHANICAL MOVEMENTS.
Specification forming part of Letters Patent No. 178,212, dated May 30, 1876; applicatioufiled March 4, 1876.
device in its other extreme position.
Similar letters indicate correspondin g parts. This invention consists in the combination of two disks or indices, one of which has a motion independent of the other, and a shaft, which is provided with a tooth to impart a step-bystep motion to a gear-wheel which connects, by means of an eccentric wrist-pin and a pitman-rod, with the movable disk or index, either the shaft or the disks or indices being made to revolve, so that an irregular step-by-step motion is imparted to the movable disk or index, whereby various results can be accomplished.
In the example shown in the drawing, the letter A designates a cam-disk, which is provided with a low section, a, and with a high section, b, the radius of the low section being made to increase gradually until at the point 0 said radius becomes equal to the high section, while the high section joins the low section by a shoulder, 0. The disk A turns freely on the hub 01 of a plate, 1.3, and on said hub is securely fastened a stationary cam-disk, O, which corresponds in shape and size to the movable cam-disk A. The hub 01 of the plate B is bored out to receive the shaft D, which extends through the plate and the two camdisks, and revolves freely in the same. Said shaft is provided with a tooth, c, which engages with a ratchet-wheel, f, that turns freely on a stud, g, secured in the plate B, and to which is firmly attached a pinion, h, which gears in a cog-wheel, a, mounted on a stud, j, secured in the plate B. From the movable cam disk A projects a stud, it, through a segmental slot, 1, in the plate B, and said stud connects, by a rod or link, m, with an eccentric wrist-pin, n, fastened in the cog-wheel c.
In the position shown in Fig. 3 the movable cam-disk A covers the stationary cam-disk G, the shoulder o of the former being situated exactly over the shoulder 0 of the latter. As the shaft D revolves the movable disk A gradually recedes to the position shown in Fig. 1, while the point 0 of said movable cam-disk approaches the shoulder 0 of the stationary cam-disk, and when the motion of the shaft D proceeds the movable disk A advances again toward the position shown in Fig. 3.
It will be seen from this description that by my device the continuous rotary motion of the shaft D is converted into an oscillating or reciprocating rotary motion of the disk A but thismotion of the disk takes place step by step, and it is not uniform. Said disk reaches its extreme positions (shown in Figs. 1 and 3) when the eccentric wrist-pin n passes through a right line drawn through the studs j and is. As the motion of the cog-wheel iprogresses from either of these extreme positions, the motion imparted by the successive impulses .of the cog-wheel '6 gradually increases, until the eccentric wrist-pin comes to such a position that a line drawn through it'and the stud j is at right angles with the linej la, and then r the steps of the disk A decrease again, until it reaches again one of its extreme positions.
It is obvious that the same result is produced if the shaft D remains stationary and the disks are caused to revolve.
My mechanical movement may be used to produce a variable cam, or to produce an index, whereby the variations in the length of day and night are shown; or it may be used to indicate the variations in the motion of the moon,'or for any other purpose Where it is desirable to convert a continuous rotary motion into a graduated rotary step-by-step motion.
When two disks or two indices' are to be combined, which move in opposite directions, the connection is such as indicated in Fig. 4 of the drawing. In this case a'small crank, n", is secured to the eccentric wrist-pin n,'and the outer end of this crank connects, by arod, or, with a stud, 76, attached torthe second disk, while the stud 7c is secured to the first wheel that connects, by an eccentric wrist-pin and pitman-rod, with the movable disk or in-,
dex, either theshaft or the disks or indices being made to revolve, substantially as shown 7 and described.
In testimony that I claim the foregoing I have hereunto set my hand and seal this 28th day of February, 1876.
