sarn'r'r nnvrcn rrvnnannrc application jl ortlZ wiromit may concern: a M i it known that 1, Jon llihlfllifllf, a c1t1- men of the United States residing at lilagle Lake. in the county of Colorado and State oi? Texas, have invented certain new and us llrnprovements in a @aiiety D'QVICG for fl-lydraulic Presses is a specification. V I
This invention relates to a safety device for hydraulic presses and has for its princr pal objectto provide means for preventing the rain iii-om; being forced CFIOHX the cylinder in which saine operates. .[hnother object of the invention to provide means whereby bale may be formed oi a uniform desired size.
it still further objector the invention is toproduce a safety device of this nature which will be of extremely simple, durable and inexpensive construction; one which is etilcient and reliable in operation and well adapted to thepurpose for which it is designed.
With these and numerous other objects in view, the invention resides in certain novel :t'eatures of construction and the combination and arrangement of parts as will be hereinafter fully described and claimed.
lln the drawing H l igure 1 is an elevational vlew of certam .portions of a hydraulic press, parts belng shown in section, with. my safety device attached thereto,
lt igure is a top plan view of the safety device, and
ll igure 3 is a sectional view taken. throu gh a portion thereof. v i
hleterrin c; to the drawing in detail it will i i be seen that represents the usual support uponwhich mounted the cylinder B which slidabl-yreceives the 1*01111 C having nounted upon its upper end the bloclr 1D. The water pipeE communicates with the cylinder so that the water under pressure will force the ram C upwardly. The parts thusclar described are of conventional construction and well known in the art of hydraulic presses.
lieved through the return pipe 3 and the upward. movement of the rain G will stop.
filed March 24,1921, Serial No. 455,254 Renewed. November fiftfl' ft.
oi? which the following This valve is pontrolledby thelever at oted on the bracket 5 and having the valve operating rod 6 pivoted. to the lever l intermediate its ends. lit the end of the lever i there is mounted the weight *1 which is preferably of cylindrical construction having a central bore extending therethrough for receiving the lever as shown in Figure A." conical shaped. receptacle 8 is fixed to the weight in any suitable manner. A chain is attached to the weight *4 so asto extend through the bottom or the conical. shaped receptacle 8 and the other end or this chain 9 is attached. to the follow block B. a
The chain 9 will be of such a length so that when the ram (l is in its lifted position i as shown in Figure l the chain 9 will be taut and as the ram C is lifted upwardly from this point the chain 9 will pull upwardly upon the lever i thus opening; the valve 1 so that thewater may return through the pipe 8 and thus the upward, movement or the ram G will cease. lt hen the pump is stopped which forces the waterthrough pipe E the rain C will be lowered and the weight *i' will close the valve 1 and particular attention is called to the utility oi the conical shaped receptacle 8 which will receive the chain as the follow block moves downwardly toward the lever 4 thus preventing the chain from catching into parts of the apparatusor other objects which may be positioned around the hydraulic press. i
From the foregoing description taken in connection with the accompanying draw inn, the construction and operation of the safety device will he readily understood without a more extended explanation. As
in the minor details or construction may be resorted to without departing from the spirit oi? this invention, I do not wish to he liniited to the construction herein shown and described other than as claimed.
. Having thus described my invention what ll claim as new is:
1. In combination with a rain of a hydraulic'press, a safety device including a chain connected at one end to the ram. a valve communicating with the intake pipe of the hydraulic press and the return pipe thereoifl said chain being connected to said valve, for operating same in the manner and for the purpose specified 2. A. safety device to be used with hydraulic presses comprising a valve, a lever for for a Weight situated on the lever so as tonormally hold the valve in a closed position, a conical shaped receptacle stiuated on the Weight, a chain connected to the weight through the hottom of the receptacle in the manner anti. tor the purpose speeified.
In testimony whereof I afiix my signature in presence of two witnesses.
