IMPROVEMENT IN MECHANICAL MOVEMENT.

TO ALL WIIOM IT MAY CON CERN:

Bc it known that we, CHARLES D. SNELL- and JOHN W. PENNEY, of Mechanic Falls, in the county of Androscoggin, and Stateof Maine, have invented a new and improved Mechanical Movement; and We do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification. I I

This invention relates ta mechanical movement, and consists in a device for running shafting at any anglc'vithout the use of the bevel-gearing. i

1lhe accompanyngdraw'ng is a perspective view of our device.

Similar letters ofrefer-ence indicate corresponding parts.

A is the revolving shaft, the motion whereof is-to be imparted to another shaft B, making any angle with A. C is an upright,on which slides the long collar D, having the planes of its faces at-- right angles to the planes in which lic the axes ef the shafts respectively, so that if the shaftings are to be at right angles to one another the collar D Will-have a rectangular. section. A pitrnan, E F; is attached to the cranks a and b respectively, and connects them with another long collar, G, sliding in grooves in the faces of D.

A rotary motion being given to the shaft A,the pitman E carries the collar- G up and down the grooves in D, and imparts an oscillating motion to'the crank band shaft B, the Pitman F not being carried to the deadA point.' An oscillating motion may in like manner be converted into a rotary, (back.) To convey a rotary motion to the shaft B from the rotary shaft A, the rods Hand K are attached to the ends k and 7c of the cranks a and b, cccentrically to the 'axes of A ,and B, pivoted at their other extremities to those faces of the long'collarD which are presented to these axes of A and B. As the shaft A now revolves, besides the sliding motion of G in the grooves of D, a sliding motion is imparted by the rod or pitman H to D upon the upright C, which carries the shaft B, by means of the rod K, over thedead-points of E and F, imparting a rotary motion to B. A and B may be inclined to one another at any angle, and may be situated inpany planes, the position ofthe upright C being varied accordingly.

Weclaim as new, and desire to secure by Letters Patent- 1. The sliding collar D, in combination with thc'upright C, or its equivalent, and in combination with the pitmcn H and K, or their respective equivalents, in manner' and for the purposes substantially as described.

2. The-collar G, sliding in the slidingcllar D, and in combination with it and with the upright C, or its equivalent, vin manner and for the purposes substantially as described.

The sliding collar G, in combination with the pitmen E andF, or their respective equivalents, and in combination with the cranks a and b, in manner and for the purposes substantially :ts-described.

4. The'ptmen E, F, II, and K, and collars-D and G, in combination with the shafts A and B andcranks a and b. all substantially as above set forth and described.
