The use of the rolls between the actuating member I 6 and the bar l forms an eflicient power transmitting mechanism in which little energy is lost through friction and in which there is no lost motion between the members. It

will be evident that the rolls 24 may be substituted by balls if desired. Such use of balls in place of the rolls is shown in the modification 2,894,676 1 ,iTi

the tube being inclined in the block as indicated inFig. 3. The motion of the balls is effected by an actuating member 55 carrying pins 58 engage- .able with the outermost balls of the series, the pins being adjustably secured to the member 56 by set screws 60. e

A bar' or driven member 62 is carried for movement along the upper surface of the block 54 at right angles to the path of movement of the actu- 7 ating member 56. For thus guiding the bar 62 a guide 64 is secured by screws 66 to the top of the block 54'. The bar 62 carries a depending pin 68 which passes downwardly through a slot formed in the block and communicating with a slot 10 (Fig. 4) in'the tube 52. The lower end of the pin 68 is received between a pair of the balls 50 so that uponmovement of the balls by the ac- ;tuatingmember 56 motion is transmitted through the pin 68 to the bar '62 which is thus moved in a direction at right angles to the direction of the actuating member 56 and in a different plane.

1 I From the above it will be seen that a very simple, easily assembled antifriction mechanical movement is provided in which motion is transmitted from one member to another member for movement along a path at an angle to the path of movement of the first member.

" Having thus described the invention, what I claim as new and desire to secure by Letters Patent of the United States is: I

1. In combination, a member arranged to be moved along one path, a member movable alon a path at'an angle to the path of movement of the first named member, and means for transmitting movements of one member to the other member comprising a series of antiiriction elements, means for confining said element for movement along a path an intermediate portion of which is in the direction of movement of one of said members and the outer portions of which extend in the direction of movement of. the other member, means carried by said one of said members projecting between a pair of said elements in the intermediate portion of the path, and means carried by the other of saidmembers engageable with the outermost elements of the series.

2. In combination, a member arranged to be moved along one path, a member movable alon a path at an angle to the path of movement of the first named member, and means for transmitting movement of one member to the other member comprising a support having a bore therethrough, a series of antifriction elements confined for movement along said bore in a path, an intermediate portion of which is parallel to the direction of movement of one of said members and the outer portions ofwhich are parallel to the direction of movement of the other of said members, means connecting one of the elements 7 in the intermediate portion of the path to one of said members, and means carried by the other of said members engageable with the outermost elements of the series.
