WINFIELD S. LIVENGOOD, OF KANSAS CITY, MISSOURI, ASSIGNOR TO SMITH & SONS MFG. CO., OF KANSAS CITY, MISSOURI.

BALlNG-PRESS- specification of Letters Patent.

Patented Jan. 2, 1906.

To aZZ whomit may concern;

Be it known that I, WINFIELD S. LIVEN- GOOD, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new.

.of the power upon the head-block as the latter approaches the end of its forward movement.

' The principal feature of the invention resides in the combination of a baling-case, a head-block reciprocably arranged therein, a cylinder, a piston-head reciprocably arranged in the cylinder, and means connecting said head-block to said piston-head, whereby the former is caused to advance about triple the distance of said piston-head.

The invention further consists in the novel construction, combination, and arrangement of parts hereinafter described, and pointed out in the claims; and in order that it may be fully understood reference will now be made to the accompanying' drawings, in which- Figure 1 represents a vertical longitudinal sectional view taken on line I I of Fig. 3 of a baling-press embodying my improvements with the head-block at the end of its backward movement. Fig. 2 is a Vertical longitudinal section of same with the head-block near the end of its forward movement. Fig. 3 is a plan view of same. Fig. 4 is a vertical cross-section of the baling-case, taken on line IV IV, showing a yoke with rollers journaled thereon employed in carrying out the invention; and Fig. 5 is a modification of same.

In said drawings, 1 designates a balingcase of any ordinaryl or preferred construction provided with a hopper 2, through which material is fed into the feed-chamber 3. Said baling-case is mounted upon a pair of carrying-wheels 1a in order that it may be readily transported from place to place.

4 designates a single-acting engine comprising a horizontal cylinder 5,` provided near its closed end with a port 5'U and at its open end with right-angled portions 6, whereby it is secured to the forward end of the balingcase; a piston-head 7, reciprocably arranged in said cylinder; a valve-casing 8, having an inlet 8b, and a balanced valve 9, having inlet and exhaust ports 9a 10, which alternately register With port 5a, and thus control the ingress and egress of the motive fiuid to and 'from the cylinder. Valve-casing 8 is provided with a centrallydisposed depending knob 8a, adapted to be swiveled to a vehicle employed in drawing the press from place to place.

11 designates a valve-lever secured to one end'of valve 9 by a set-screw 12.

13 designates a hand-lever fulcrumed at its lower end to the lower portion of the baling-case and extending' upwardly in the rear of hopper 2 within convenient reach of the workman employed in placing hay into the feed-chamber '3.

14 designates a 'connecting-rod pivotally secured at its ends to levers 11 and 13, respectively.

15 designates a pair of piston-b ars pivotally secured at their ends to piston-head 7 and the rear member of a toggle 16, comprising two links 17 18, respectively. Link 18 is pivotally secured at its forward end to headblock 19, which latter is provided at 'its opposite sides with a pair of longitudinal fianges 20, the upper edges 21 of which are turned inwardly to form a broad surface for rollers 22, against which said inturned portions bear during a part of the forward stroke of the head-block, and thus prevent the latter from tipping forward while condensing the loose material in the feed-chamber. f

23 designates a pair of guide-rollers arranged at opposite sides of the toggle and bearing upon the upper surfaces of the piston-bars.

24 designates a long guide-roller which bears against the under sides of the pistonbars and in conjunction With rollers 23 main- ,tains said piston-bars in a horizontal plane as they move on their forward and backward strokes.

Rollers 22 and 23 are journaled' upon IOO to it is transverse shafts 25, eXtending through the sides of the baling-case and the sides of a yoke 26, which latter comprises a U-shaped member 27, bolted at its lower side to the bottom of the baling-case, and an arched transverse member 28, secured to the upper ortion of the baling-case and the up er en s of said U-shaped member` 27. Gui e-roller 24 is journaled upon a transverse shaft 24a, eX- tending through the lower portion of the yoke. One side of link 17 also bears against roller 24, and thus causes the toggle to straighten out to the position shown in Fig. 2 when the piston-head advances. After said toggle attains the position above referred revented from accidentally folding while a vancing by means of roller 24 and a pin 29, which latter is engaged by the notched end 17a of link 17. Pin 29 extends transversely through the piston-bars to which it is riveted in order to brace said bars and prevent them from springing laterally while pressure is eXerted thereon when making a forward stroke.

The forward strokes of the piston-head are ordinarily limited by drawing hand-lever 13 to theposition shown by dotted line a, Fig. 2, and vthereby cutting off the flow of motive fiuid into the cylinder; but in order to guard against said piston-head being forced out of the open end of the cylinder through failure of the workman to operate the handlever at the proper time I provide a positive stop in the form of a pin 30, extending transversely through the piston-bars, from the outer sides of which latter it projects in order that said projecting ends may contact with the rear side of yoke 26. The backward movement of hand-lever 13 is limited by valve-lever 11, contacting with a stop 11a, projecting laterally from the ,closed end o f the cylinder, and when the valve-lever is in contact with said lstop eXhaust-port 10 is in coincidence with port 5a, so the motive fiuid may eXhaust from the cylinder and permit the pistonhead to move backwardly. After the headblock has reached the end of its forward stroke and the supply of motive fluid has been cut off from the cylinder said headblock is returned to the end of its backward stroke by means of the expansive force of the material in baling-chamber 31 and the retractile spring 32, which latter is secured at its ends to a Vertical arm 33 on the closed end of the cylinder, and a screw-eye 34, secured to link 17 near the toggle-joint 35.

In the modification Fig. 5 yoke 26CL is composed of a single casting and rollers 22a are mounted upon shafts 25a, located beneath shafts 25, carrying guide-rollers 23, that bear upon flanges 20a, which latter are of less height than flanges 20 and are preferably formed integral with the head-block instead of being riveted thereto, as are said flanges 20.

The following is a brief description of the operation of the baling-press: After a charge of hay has been placed in feed-chamber 3 the workman standing upon the baling-case draws hand-lever 13 to the position shown by full lines, Fig. 2. This movement of the hand-lever opens the valve and permits the motive fluid to flow into the cylinder and force the piston-head forwardly. As the piston-bars advance link 17 is Vushed over roller 24, and thus uickly unfol s the toggle, which advances t e head-block at about triple the speed to that traveled by the iston-head until said toggle is fully exten ed, when it, the head-block, and the piston-head all move at the same rate of speed. After the toggle has become fully extended direct pressure of the motive fiuid upon the pistonhead is transmitted to .the head-block during the remainder of the stroke. When the piston-head has completed a forward stroke, the flow of motive fluid into the cylinder is shut off, so that the head-block maybe immediately returned to its starting-point through the recoil of the compressed hay in balingchamber 31 and the retractile spring 32, and as the piston-head moves backwardly toward the closed end of the cylinder it will be stopped before striking said closed end by the escaping motive fiuid, which acts as a eushion between said piston-head and the closed end of the cylinder. As the pistonhead nears the closed end of the cylinder the eXhaust of the motive fiuid through port 9 is retarded by the piston-headpartly overlapping said port, and thus temporarily reducing its area, as shown in Fig. 1.

From the above description it is obvious that I have produced a baling-press wherein a long travel of the head-block is obtained with a comparatively short stroke of 1the pistonhead, and although the initial forward movement of said head-block will be rapid and attended with but little power the final part of said forward movement will be accomplisied with direct pressure ,of the motive flui Wh'i'le I have shown and described the preferred 'construction of my baling-press, I of course reserve the right to make such changes as properly fall within the scope of the appended claims.
