BALlNG-PRESS.

SPECIFICATION forming part of Letters Patent No. 396,097, dated January 15, 1889. Application filed March 9, 1888. Serial No. 266,743. (No model.)

To all whom it may concern.-

Be it known that I, W'INFIELD S. LIVEN- GOOD, of Kansas City, Jackson county, Missouri, have invented certain new and useful Improvements in Baling-Presses, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention relates to baling-presses; and it consists in the peculiar features and combination of parts more fully described hereinafter, and pointed out in the claims.

In the accompanying drawings, which illustrate the manner of carrying out my invention, Figure 1 is a transverse sectional elevation looking from rear, and showing the front end of the press mounted on its supportingwheels, the section being taken on line 0c 50, Fig. Fig. 2 is a sectional plan view showing the circular track for supporting the front end of the pitman and its connections. Fig. 3 is a broken plan view showing the entire front end of the machine. Fig. at is a detail View, in perspective, of the head-block used in making up the invention. Fig. 5 is a section through the pitman and a bumper located thereon. Fig. 6 is a detail view showing the scraper hinged to the face of the head-block or plunger at the lower side of same, and Fig. 7 is a broken detail view illustrating the manner of connecting the pitman to the plunger by a swiveling joint.

At the beginning of this description I would state that my press is to be mounted on supporting-wheels, so that it can. be moved from place to place, and I have therefore so shown it in the drawings.

The letter A indicates the reach which connects the forward axle to the rear portion of the press, and the trip-lever shaft C, which may be termed the ki ng-bolt, passes through its forward end.

The front axle of the machine is in the form of a truss, G, the lower portion, G, of which forms the axle, and has the supporting-wheels 100 located thereon in any desired way, and the upper portion of which is in the form of an arch extending parallel with the lower portion, and in which the upper end of the triplever or power-shaft C is journaled, as shown more clearly in Fig. 1.

For the purpose of keeping the truss G in a vertical position, a connecting rod or bar, D, is extended in a longitudinal direction a suitable distance, and has its lower end firmly connected to the baling-chamber B in any desired way, and its forward end being connected to the upper end of the trip-lever shaft 0 by means of a suitable casting, E, and a stirrup, F, which embraces said casting. The casting is firmly secured in the arch of the truss. On shaft 0, between the axle and the arch, I locate a pair of links, H, and the trip-lever J, said trip -lever being located between said links or arms. These links are loosely mounted firmly secured to said shaft, and consists of two arms extending in the same longitudinal direction. heels 99 are mounted in a horizontal plane in the extreme outer ends of the trip-lever, so as to engage a curved track, 3, formed on the inner side of casting 2, said wheels rolling around said track as the pit man is advanced by the action of the trip-lever and links H, and the sweep K is revolved. It will be understood that the power-shaft and sweep K are to be continuouslyrevolved in the direction indicated by the arrow in Fig. 3. v

The operation of this construction is as follows: The sweep K is caused to turn in acircle. The wheels 99 at the ends of the arms of the trip-lever are then in their relation brought to bear against the side of track 3, and then, as the movement continues, they roll around upon the end of the casting 2, which forces said pitman toward the baling-chamber of the press, the links H acting to guide the pitman and the trip-lever in their mutual relation till the pitman is released by said wheels running off the end of the casting. By the use of such arrangement much friction is done away with and the press is put in position to exert much greater power upon the material to be compressed than it otherwise could. A bumper or stop, 55, for absorbing the shock caused by the recoil of the pitman, is located on said pitman at such distance from its front end as to engage the center of the power-shaft or a projection, 15, formed thereon. This bumper consists of a casting, '7, which is clamped to the pitman by means of a stirrup, 8, orlocatcd thereon in any desired way. This bumper or casting should be, and preferably is, provided with a rubber cushion, 9, having a metallic contact-piece, 10, said rubber cushion being located between said metallic contact-piece and the main casting of the bumper. If so desired, however, the rubber cushion may be dispensed with and the operation will be substantially the same. The casting 2 is connected to the outer ends of the links H by means of a bolt, 4, which passes vertically through the several parts. For the purpose of removing some of the lateral strain on this bolt, caused by the considerable weight of the casting 2 and its connections, I form a suitable projection, 5, on the under side of said casting and a corresponding projection, G, on the upper side of the lower link II, so that the projection on the casting will rest upon the lug on the link and support most of the weight during movement of the parts, as shown more clearly in Fig. 1.

For removing lateral strain from the power or trip-lever shaft 0, which has occurred heretofore, I locate a circular track, L, on the front axle of the machine, or on the framing thereof, and locate a wheel or roller, L, in suitable bearings in the lower link II, so as to engage said track when said links vibrate during operation of the machine. In this way a considerable amount of friction in these parts, which has heretofore occurred, is obviated. Said track is secured in place by means of bolts 1 or by other suitable devices. It will therefore be observed that the truss in which the power shaft or trip lever shaft 0 is mounted and supported also forms the front axle of the machine, and that as such it is capable of being swung around in either direction in turning the machine, just as an ordinary front axle would be.

The hounds 16, or the devices by means of which the pole is attached, are directly connected to the lower portion, G, of the truss.

The letter 0 represents the plunger, which is provided on the lower part of its front face with a downwardly-swinging plate or scraper, 4G. (Shown more clearly in Figs. 4, 7, and 6.) This scraper is so hinged at its upper edge to the plunger that it becomes a portion of the face thereof, and in a normal position hangs in a vertical plane, as when the plunger is making a stroke and compressing the material. NV hen the pitman is released, however, and the plunger withdrawn, said plate swings outwardly, as indicated by dotted lines in Fig. 4, and passes freely over any leaves or straws which may have accumulated in the bottom of baling-case during the forward movement of the plunger.

' In moving toward the material it will thus be seen that the scraper 46 comes in intimate contact with the bottom of the baling-chamber, scraping all the material therefrom in a very cleanly way, and yet hindering 'in no wise the recoil action.

I may say that the plunger 0 is constructed in two sections-a main section, 0, whichis connected to the pitman, and an upper forward section, 0", which is loosely connected to the rear sectionso that when the recoil takes place and the plunger is withdrawn the forward and upper portion will drop a sufficient distance to relieve the plunger of the downward pressure produced by the hay or other material. overlapping its top, and not retard the backward movement of the pitman. Likewise when the plunger makes a compression stroke said forward section will be forced upwardly and in close contact with the top of the balingw chamber. This construction is indicated clearly in Fig. 7, the main section of the plunger being inclined downwardly and the front section being correspondingly inclined and loosely connected at its upper end to the main section by means of links 75, provided with balance-weights 78.

Of course it is evident that any desired form of devices can be used for connecting the section 0 to the main section of the plunger, and I do not desire, therefore, to be limited to the exact details that I here show. In operating presses of this class, which are usually of considerable length, I have experienced much difficulty in setting the frame so that it will not be twisted, in which position much strain and friction have been thrown on the working parts, particularly the plunger and its connections. To obviate this disadvantage, I locate a swiveling joint, such as N, at any point between the power mechanism and the plunger. This j ointcan be made and located in any desired way, although I prefer to locate it at the junction of the plunger and pitman, as shown, in which latter case I provide said plunger with a socket, 23, and the plunger with a shouldered casting, I. I 10- cate this shoulder in said socket and secure it in place by means of a ring or sleeve, 20, secured in place by bolts 24, the shoulder on the casting coming in contact with said ring while the pitman is moving in one direction and the free end of casting I pressing firmly against the'bottom of the socket 23 when the pitman moves in opposite direction.

Having thus described my invention, what I claim is 1. In a baling-press, a pitman-rod provided with a bumper consisting of a hard base, a rubber cushion, and metallic contact-piece located upon the outside of the rubber, in combination with a stirrup for securing them to the pitman, substantially as described.

2. In a baling-press, a plunger-head con-= sisting of a main section, in combination with a counterbalanced section hinged to and hanging over the front of said main section, in the manner and for the purpose described.

3. In a baling-press, a plunger-head com IIO posed of two sections consisting of a main.

rear section attached to the pitman-rod and a counterbalanced upper section arranged to hang over the front face of said main section, in the manner and for the purpose set forth.

4. In a baling-press, a plunger-head consisting of a main section, in combination with a movable section hinged to and hanging over the front face of said main section, in the manner and for the purpose substantially as described.

5. The combination, in a baling-press, of a plunger composed of two sections,as described, a scraper hinged to the front of the main section thereof, a counterbalanced section hinged above said scraper and to the main section, a

swivel jointed pitman rod and actuating mechanism, substantially as described.

0. In a horizontal baling-press, a recipro-. eating plunger composed of two parts, the forward upper end of the lower or main part being inclined upward and backward, and the rear side of the upper part correspondingly inclined and adapted to slide on the incline of the main part, substantially as described.

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