LEVER MECHANISM FOR BALING-ERESSES.
Specification of Letters Patent.
Patented Dec. 23, 1913.
Application filed January 16, 1913. Serial No. 742,503.
To all whom it may concern Be it known that I, GEORGE B. SWAN, a citizen of the United States, residing at Cross Plains, in the county of Callahan and State of Texas, have invented new and useful Improvements in Lever Mechanisms for Baling-Presses, of which the following is a specification.
The present invention has reference to press-operating lever mechanism, and it comprehends, briefly, an improved lever mechanism specially designed for hand baling presses, the lever being so constructed and arranged as to cause the plunger to exert a maximum pressure upon the material to be baled during a comparatively short stroke.
An embodiment of the invention is illustrated in the accompanying drawing, of which Figure l is a longitudinal vertical section of a hand baling press equipped with the improved operating lever mechanism; and Fig. 2 is a fragmental perspective view of the aforesaid lever mechanism and the plunger to which it is connected.
In said drawings, A indicates, generally, a baling press of any suitable type, and B the lever mechanism for operating the plunger C. The press A embodies the usual chamber 1 and hopper 2, and its floor 3 is extended rearwardly of the aforesaid hopper and constitutes a support along which the plunger travels, that element having connected to its head a a pair of triangular frames 5 whose horizontal lower members also travel along floor 3. These frames are joined by front and rear horizontal bars 6 and 7, the latter of which is located at the apices of the frames, and there are also secured to the rear face of the plunger head a series of three vertical cleats 8 arranged in spaced parallel relation. In the spaces between said cleats are pivoted the forward ends of a pair of relatively short links 9 that extend toward the rear end of the press and have pivotally mounted between them, adjacent their rear ends, the lower end of a lever 10 included in the aforementioned mechanism B. This lever is fulcrumed slightly below its center upon a horizontal bolt 11 mounted at its ends in the inclined side rails 12 of the press, and, in its normal position, is itself inclined slightly forwardly toward hopper 2. At its upper end, lever 10, which may be regarded as the secondary lever of mechanism B, is pivotally connected by a pair of relatively short links 13 to the main lever 14, that lever being fulcrumed at its lower end to a second horizontal bolt 15 supported in rails 12 below and to the rear of bolt 11. The lower ends of links 18 are pivoted to the lower portion of lever 14: a short distance above bolt 15, and the latter is located in comparatively close proximity to bolt 11, as shown.
When the elements included in the lever mechanism are in normal position, as indicated in full lines in Fig. 1, the plunger lies to the rear of the baling chamber and the hopper, thus permitting material in the latter to fall onto floor 3. When the main lever 1 1 is swung rearwardly upon its fulcrum 15, into the position shown in dotted lines in Fig. 1, it will cause links 13 to move in the same direction, and they, in turn, will swing the upper arm of lever 10 correspondingly, whereupon the lower arm of that lever will be caused to move forwardly and, through the intermediary of the links 9, will force plunger C forwardly into said chamber, thereby compressing the material therein and forming the bale. It will be observed that during its effective movement the main lever 14 swings through an arc of somewhat more than 90, and that its mounting is such as to afford maximum leverage, while the links 13 are connected to the longer arm of the secondary lever 10, so that the maximum pressure is exerted, by way of the links 9, upon the plunger, which latter, travels through a very short distance only. It is also to be noted that the arrangement of levers, in addition to affording a maximum leverage, is also such as to render the apparatus as a whole extremely compact, owing to the relatively short link connections 9 and 13 which are utilized, and to the juxtaposition of the fulcra 11 and 15 of the levers.
To facilitate the operation of the main lever, the main side rails 16 of the press may be extended rearwardly beyond the press floor and connected by a cross-board or plank 17, thus providing a platform upon which the operator stands during the first part of the effective movement of said lever.
I claim as my invention In a press, the combination, with a press 119 chamber and a plunger working therein; of a lever mechanism for operating the plunger comprising a main lever fulcrumed at its lower endin the press frame, a secondary lever fulcrumed intermediate its ends in said frame in close proximity to the fulcrum of the main lever, a short link connection between the lower portion of the main lever and the upper end of the sec- 10 ondary lever, and a short link connection GEORGE B. SWAN.
