MECHANICAL MOVEMENT.

SPECIFICATION forming part of Letters Patent Novl 764,172, dated July 5, 1904.

Application filed August l, 1903.

[o all wil/07), llt muy concern,.-

Be it known that I, HENRY BRAMMER, a citizen of the United States, residing at St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Mechanical Movements, of which the following' is a full, clear, and exact specification, reference being had to the accompanying drawings.

The object of my invention is to provide an economically-constructed mechanism for converting the continuously-revelving motion of a drive-shaft into a rotary reciprocal motion of a shaft arranged at right angles thereto, which is particularly adapted for use in washing-machines, churns, &c.; and its object is also to so construct this mechanism that there is an actual controlled engagement of the drivepinion with the sliding sleeve or cylinder on the rotary reciprocal shaft during' the entire cycle of their movements. This l accomplish by the means hereinafter fully described, and as particularly pointed out in the claims.

ln the drawings, Figure l is a side elevation of my invention with part of the fly-wheel broken away. Fig, 2 is a horizontal section taken on dotted line 2 2, Fig. l, looking in the direction indicated by the arrows.

In the drawings, A represents a suitable frame by means of whichthe movable parts of my invention are assembled and retained in operative engagement. This frame comprises a long narrow screw-plate, having lateral lugs projecting from each end that have laterally-elongated screw-slots therein, and two vertical members that-have bearings therein for the drive-shaft B, The vertical member nearest the fly-wheel @which latter is secured on the outer end of the drive-shaft B, is preferably less in height than the other vertical memberl and has its upper end connected to the upper end of said other member by a suitable reach that extends beyond the same and is bent horizontally to form an overhanging arm a. The unsupported end of the arm a is provided with vertical bearings for the upper end of a rotary reciprocal shaft D, and immediately below these bearings the screwplate of frame A is provided with bearings I) for the lower portion of said shaft D. Between its bearings shaft D is preferably made Serial No. 167,870. (No model.)

square, and mounted on this square portion of said shaft is a longitudinally-slidable cylinder E. The ends of this cylinder are prol vided with enlarged heads c, and projecting laterally from these heads are iiuted segmental flanges CZ and e. The downward bends of the corrugations of the upper iange CZ and the upper bends of the corrugations of the lower flange e serve as cogs, thus constituting said flanges segmental gears. The ends of these ianges do not extend clear around the heads c, but terminate within, say, thirty degrees (300) of each other, the ends of the upper flange Z bending downward correspondinglyand terminating at or adjacent to thc lower shoulder formed by the upper head c and the ends of the lower iiange c being bent correspondingly upward and terminating at or near the upper shoulder formed by the lower head c of the cylinder. The right ends and the left ends of these upper and lower fluted flanges respectively terminate in the same vertical planes and in a vertical plane midway between the planes in which the ends of the liuted flanges are in. rlhe cylinder is provided midway its length (and consequently midway between said flanges) with a radially-projecting stud F, which extends slightly beyond the circumference of the periphery of the iianges. This stud is preferably of a flattened-cone shape with its major axis horizontal, and the truncated apex of this stud is secured to and made integral with the cylinder. Midway between the iianges Z and and in the same transverse plane as the stud F the cylinder is lprovided with a segmental guide-iiange Gr, the radius of which is slightly less than that of the heads c c and the ends of which terminate a suitable distance from the 'sides of the stud F, substantially as shown in the drawings. The end g of the drive-shaft opposite the fly-wheel C extends through its bearings to within a short distance of the barrel of the cylinder.

E and to a point within the circumference of the periphery described by the guide-iiange Gr, and immediately next its adjacent bearings it is provided with a spur-wheel H, which is so located and is of such diameter that when the extended end g of the shaft B engages the under side of the guide-flange Gr it engages IOO the corrugations of the lower flange e, and when the end g of said drive-shaft engages the upper side of the flange r/ its upper segment engages the upper fluted flange.

The operation of my invention is substantially as follows, to wit: Then the cylinder is in the position shown in Fig. l and the extension g of the shaft B is under the guideflange G and the drive-shaft is revolved in either direction; the lower segment of the pinion H will engage the corrugations of the lower fluted flange e of the cylinder and turn the same, together with the shaft D, until the end r/ of shaft B is in the same radial plane as the space between the stud F and one end of flange G. Upon arriving in this position the pinion H engages the stud F; and extension c/ of the shaft B passes between the said end of the flange G and said stud. The pinion H causes the cylinder to slide downward on shaft D until the extension g is in a plane above the flange G and the upper segment of pinion H engages the corrugations of the upper flange d, whereupon by reason of the upper segment of the pinion moving in a direction opposite to that in which its lowermost segment moves it reverses the motion of the cylinder and rotates the shaft D in the opposite direction. rlhis rotation of the cylinder E and the shaft D continues until the pinion arrives at the end of the flange Z opposite the end first engaged by the same, whereupon, first through the engagement of the end of the flange by pinion H and then by the engagement of the stud F by said pinion,with which it is kept in engagement by the extension a passing between the adjacent end of the flange Gr` andv stud F, the cylinder is raised to the limit of its upward movement and the direction of the rotation thereof and shaft D is reversed by reason of the engagement of the lower segment of the pinion H with the lower iiuted flange e. It will be observed that at no time during the cycle of the movements dcscribed by the cylinder E and. pinion H is there any lost motion, and the two parts are in operative engagement in such manner as to run smoothly and noiselessly all the time.

l/Vhat 1 claim as new is- 1. A mechanical movement comprising acontinuously-revolving shaft; a rotary reciprocal shaft; a cylinder sliding longitudinally on and through which alone motion isimparted to said rotary reciprocal shaft the ends of which 'are provided with opposing segmental gear members; a segmental guide-flange projecting from said cylinder midway its length;

a suitable stud projecting radially from said cylinder intermediate the ends of said guideilange; and a pinion on the contiguous end of Said continuously-revolving shaft which latter extends beyond the same and engages said guide-flange and stud. i

2. A mechanical movement comprising a continuously-revelving shaft; a rotary reciprocal shaft; a cylinder sliding longitudinally on and through which alone motion is imparted to said rotary reciprocal shaft the ends of which are provided with opposing segmental gear members; a suitable stud projecting from said cylinder in a plane intermediate the planes of the ends of the said gear members and midway between the same; and a pinion on the contiguous end of said eontinuously-revolving shaft which latter extends beyond the same and engages said guide-flange and stud.

3. A mechanical movement comprising a continuously-revelving shaft; a rotary reciprocal shaft; a cylinder sliding longitudinally on and through which alone motion is imparted to said rotary reciprocal shaft; fluted segmental flanges projecting from the en ds of said cylinder; a segmental guide-frame projecting' from said cylinder midway between said flanges; a flattenedconical stud projecting radially 'from said cylinder intermediate the ends of said guide-flange; and a pinion on the contiguous end of said continuously-revolving shaft which latter extends beyond the same and engages said guide-flange and stud.

In testimony whereof I hereunto set my hand this lst day of July, 1%()3.
