BALI NG- PRESS.

SPECIFICATION forming part of Letters Patent No. 447,950, dated March 10, 1891.

Application filed June 5, 1889. Renewed February 9, 1891. Serial No. 380,735. (No model.)

To aZZ whom it may concern.-

Be it known that I, MANETno O. JACKSON, a citizen of the United States, residing at Denver, in the county of Arapahoe and State of Colorado, have invented certain new and useful Improvements in Baling-Presses; and I do declare the following to beafull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

My invention relates to an improved and novel mechanical movement whereby a rotary motion is converted into a reciprocating motion, being especially designed for use in connection with a baling-press; and its objects are to furnish a power or movement in which the reciprocating pitman ormain driving-wheel by which power is transmitted to .the driven apparatus may be moved relatively slowly and with great force in one direction and broughtback or moved in the reverse direction relatively speedily, and Wherein each complete rotation of the rotary member shall causea plural number of reciprocations of the pitman-rod and its attached parts, a mechanical movementof very simple yet strong construction, compact, readily transported and arranged for operation, durable, and giving large and speedy results for the power applied thereto, to which ends it consists in the features, arrangements, and combinations hereinafter described and claimed.

In the drawings is illustrated an embodiment of the invention, wherein-'- Figure l is a top or plan view of the parts in position to make a forward stroke of the pitman. Fig. 2 is a plan view of the parts atthe end of the forward stroke. Fig. 3 is an end view of the mechanism in the position shown in Fig. 2 and observed from a point at the right of said figure. Fig. 4 illustrates a modified form of construction, the main part of the mechanism being shown in the same relative position as in Fig. 2. Fig. 5 illustrates a modified form of arrangement, all the parts, however, with the exception of the pitmanrod,-being shown in the same relative position as in Fig. 1. The pitman, however, in

Fig. 5 has just completed its forward movement and is about to begin the return orbackward movement, acted upon by the main arm. 5 5

In the figures the reference-numeral 1 indicates any suitable bed-plate upon which the parts are supported, preferably made as a cast-bed having arounded or enlarged part with an extension 2, by which it may be secured to a base or framing timber 20, connected with the machine to be operated. Projecting vertically from bed-plate 1 is a post or spindle 3, upon which is seated the main driving-arm 4:. At the extremities of this driving-arm and depending from the under side thereof are the curved projecting ridges or cams 5 and 6, preferably slightly depressed upon their faces and near their outer ends, as shown at 21. Across the extremities of main arm 4 and at an angle thereto are the interiorly-convexed depending flanges 7 and 8. The curved projecting ridges or cams 5 and 6 have their convex faces presented in opposite directions as regards the arm, so that the convex faces shall travel in the same direction as such arm is rotated. These cams are arranged to take alternately upon a roller 14, mounted upon a post or pin at the extreme end of an arm 11, projecting horizontally from a segment of the gear-wheel 10, pivotally mounted at 9 upon the bed-plate. To the outer extremity of arm 11 is also pivoted the pitman-rod 13 for connecting the mechanism with the machinery to be driven. Such pivoting is preferably by securing the end of the pitman in a slot 12, formed in the end of the arm 11. Pivoted upon a post or pintle 22, projecting also from base-plate 1, is a segment of a second gear-wheel 15, ar- 9 ranged to mesh with the segment 10 and having a projecting arm 16, upon which is seated a roller 17, arranged and adapted to be impinged upon when in proper position by the flanges 7 and 8 alternately.

The operation of these devices, motion being communicated to the arm 4 to rotate in the direction of the arrow, and the arms being in position, (shown in Fig. 1,) is as follows: The projecting ridge 5 takes upon the I00 roller 14, carried by the arm 11, forcing the roller outward and forward until the roller reaches the inner end of such curved ridge and the hub of the arm, the parts being then s eemso in the position shown in Fig. 2. At suchtime the flange 8 is about in position to contact with the roller 17, and engaging there with pushes it forward, turning the segmentary gear 15 upon its pivot, and, it meshing with the gear 10,'both are moved in the direction of the arrow shown inFig. 2, causing the parts immediately to return to the original position, (shown in Fig. 1,) and ready for another forward stroke. In order that the roller 17 may be acted upon the more readily by flanges 7 and S and avoid engagement with the curved ridges or cams 5 and (3, the roller 17 is arranged to move in a lower plane than is the roller 1-1, the flanges 7 and 8 projecting below the lower line of the ridges 5 and 6. It will be observed that arm 4: always revolves in one and the same direction, that ridge or cam (5 acts upon roller 14 in the same manner as ridge or cam 5, and that the flange '7 acts in the same manner upon roller It as flange 8.

As before stated, the device is designed more particularly for use with a baling-press, the pitman being connected with a piston or head, by means of which connections relatively slow and rapid movements are alternately imparted to the piston or plunger. It may also be here stated that there is an especial purpose in view in making the ridges inclined-namely, to cause the roller 14 to approach toward the pivotal point 3 when the pitman is near the end of the stroke. This construction gives greatly-increased leverage at or near the end of the pitman stroke.

'While a sweep 18 is herein shown connected with arm at as a means of rotating the arm, it

is evident that any other suitable means of applying power might be applied to said arm for the same purpose.

The modifications of construction and arrangement illustrated in Figs. t and 5 will be readily understood.

In Fig. 4 curved ridges or cams 25 and 26 are placed upon arms 116 and 166, respect ively, of the segmental gears 15 and 10, said cams being engaged by rollers 114; and 117, depending from the opposite extremities of the arm 4. It will be observed that in this modification the flanges 7 and 8 are dispensed with; or, in other words, there are no parts corresponding with flanges 7 and 8, as shown in the other figures. It will also be observed that rollers 114 and 117 perform a function similar to that of rollers 14 and 17 in the other figures, while the cams 25 and 26 have an office similar to that of cams 5 and 6; also, that arms 116 and 166 are similar to arms 11 and 16. This modification consists in changing the rollers from the arms of the segmental gears to the extremities of the main arms and removing the cams from the extremities of the main arms and placing them upon the arms of the segmental gears.

In Fig. 5 the position and arrangement of the pitman is such that it is drawn backward by the same movement of arm at, which thrusts it forward when in the position shown in Figs. 1 and'2, and vice versa.

It will be observed that in Fig. 5 there is no change of construction, the only modification being in the arrangement of the pitman, while in Fig. 4 the modification is in the construction, the relative position of the main parts remaining thesame as in Figs. 1. and 2.

The parts 1% and 17 are herein shown as rollers, though a rigid bearing might be used in lieu thereof, the rollers being preferable 011 account of the great reduction of friction insured thereby.

Having thus described 1nyinvention,what I claim is 1. The combination of a main driving-arm centrally pivoted and having curved projecting ridges substantially along either end thereof and flanges across its ends, a gear or segmental gear-wheel having an arm connected with a pitman-rod and carrying a roller arranged to be impinged upon by the curved projecting ridges, and a second gear or segmental gear-wheel meshing with the first and carrying a roller adapted to be impinged upon by the end flanges, substantially as set forth.

2. The combination of main driving-arm at, having curved projecting ridges 5 and 6 and flanges 7 and 8, the geansegment 10, having arm 11 and carrying the bearing 14, a pitinan-rod connected thereto, and a gear 15, carrying a roller 17, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

MANETHO O. JACKSON.
