BAL'ING-PRESS.

SPECIFICATION forming part of Letters Patent No. 553,599, dated January 28, 1896.

Application filed September 29, 1893. Serial No. 486,827. (No model.)

To @ZZ whom t may concern.'

Be it known that I, FRANK L. RoBIsoN, of Albion, in the county of Orleans and State of New York, have invented a new and useful Improvement in Power Ealing-Presses, which improvement is fully set forth in the following specification and shown in the accompanying drawings.

The object of my invention is to improve baling presses, driven by steam or other power, by means of the construction and arrange ment of parts hereinafter shown and described, and particularly pointed out in the claims.

Referring to the accompanying drawings, Figure l isa side elevation of my improved press. Fig. 2 is a plan of the same. Fig. 8 is a side elevation of the gear-frame. Fig. at is a vertical longitudinal section of the gearframe on the dotted line #l et in Fig. 2, parts being shown in various positions by full and dotted lines. Fig. 5 is a front end elevation. Fig. 6 is a horizontal section on the dotted lines 6 6 in Figs. l and al.. Fig. 7, drawn to a larger scale, shows rollers on the traverse pin.

Referring to the parts shown, B is the frame of the machine, it being substantially of common form in machines of this nature, consisting of four equal longitudinal timbers held in the form of a prism or parallelopipedon by cross-ties and binding-bolts of a suitable kind.

A is a metal gear-frame within the main frame B holding two eual vertical master gear-wheels c a, as shown.

l) is a driving-shaft for the master-wheels, resting in horizontal bearings c c at the forward end of the main frame. This shaft is provided with pinions e e to engage the master-wheels, also inertia wheels d cl and a bandpulley f, to which power is transmitted by a belt from a steam-engine or other motor.

C is the driving-head or follower for pressing the hay, adapted to travel along bearings within the main frame.

D is the pitman connecting the follower with the master-wheels and playing between the latter, as shown.

The gear-frame is formed with a large central opening and vertical side walls, the latter having longitudinal flanges p to meet the timbers of the main frame. The masterwheels are independent of each other and occupy the opening in the gear-frame, each being formed with an outwardly-projectinghub t, restingin bearings s, in the sides of the gearframe. Each master-wheel is formed with a large arm g, Fig. l, having a radial slot h, (see Fig. 6,) the wheels being placed so that said slots are opposite each other. The head of thepitman is provided with a transverse horizontal pin fz', Figs. 6 and 7, projecting at its ends through the slots h, which slots are traversed by the pin as the wheels are revolved. The pitman swings in a vertical plane in the space between the master-wheels and is connected with the follower by ahori- Zoutal pin l, Figs. 4 and G.

The vertical sides of the gear-frame A have formed in their interior opposing surfaces two equal circular grooves k, Figs. @L and 6, into which the extreme ends of the traverse pin i' also project, as shown. Now it will be understood from the construction and arrangement of the parts above described that the master-wheels drive the traverse pini as they are rotated, while the grooves 7c 7.; guide and control the pin. The grooves 7c are eccentric with the master-wheels and pass near the axis of said wheels, as shown in Figs. 4 and (i. lVhen, therefore, the traverse pin is passing the parts of the grooves near the axis of the master-wheels it m oves quite slowly and the follower is being urged against the hay with great force; also, when the traverse pin is passing the parts of the grooves farthest from the axis of the master-wheels it is being moved rapidly, the follower then being acting upon loose hay. In other words, by this construction of the parts the follower is moved relatively rapidly when doing the least work (pressing loose hay) and slower and with greater force when being driven against the body of hay pressed hard. The hay is introduced into the press at m in the usual way, a hopper (not shown) of common kind being employed on top of the frame over the opening m.

The gear-frame is made in two equal parts, it being divided longitudinally and joined by tie-bolts fr, Figs. 2 and 5, passing through projecting lugs u, Fig. 3.

I usually employ antifriction-rollers o 0 o 0,

-IOO

Fig. 7, on the traverse pin 'L' to roll in the grooves 7.1 7n' and slots 7L 7L. There is frequently great stress thrown upon the traverse pin, and these interposed rollers tend greatly to relieve the friction between the contiguous parts.

I usually construct the press with openings `n n, Figs. 4, 5, and 6, through the front of the gear-frame through which to introduce oil to the grooves 7c k and for other purposes, though these openings are not essential.

The driving-shaft ZJ may be placed above the master-wheels instead of in front of them, as shown, and in some cases I regard thus placing it preferable to placing it in front.

That I claim as my invention isl. In a baling press, the combination, With a main frame, of a gear frame therein, comprising two equal parts, each of which is provided with proj eet-ing lugs at each end, a bearing at the middle, and a circular groove eecentrio thereto, said gear frame being pro vided with a large central opening, a master wheel journaled in each bearing, and lying in said opening, and having a radiallyslotted arm, a pin through the arms, having its ends in the grooves, a pitlnan upon the pin, and a plunger connected with the pitman, substantially as set forth.

2. In a baling press, the combination, with ainain frame, of a gear frame therein, the sides of which are each provided with a bearing and a circular groove eccentric thereto, and the front end being provided With a recess leading into the groove, a master wheel journaled in each side and provided with a radially slotted arin, a pin through the arms and having its ends projecting into the grooves, a pitinan upon the pin, and a plunger connected with the pitinan, substantially as set forth.

In Witness whereof I have hereunto set my hand, this 21st day of July, 1803, in the presence of two subscribing Witnesses.
