To all whom it may concern.- V

Be it known that I, GEORGE Panama, a citizen of the United States, and a resident of the borough of Manhattan, city, county, and State of New York, have invented certain new and useful Improvements in Dumping- Receptacles, of which the following is a specification. I

My invention relates to receptacles adapted to be loaded with stone or other material at one place, then carried over to the place of discharge, and there opened at the bottom to allow the material to drop out.

The object of my invention is to provide a provision is made for the ready discharge of the material, as will be fully described hereinafter. 7

Reference is tobe hal the accompanying drawings, inlwhich Figure 1 is a perspective view showing my improved receptacle closed. Fig. 2 is a similar view showing the same open. Fig. 3 is a cross-sectional elevation. Fig. 4 *is a perspective view showing my invention in connection with a derrick structure. Fig. 5 is a perspective view showing another form of my invention, and Fig. 6 is an elevation of a portion of the ap aratus shown in Fig. 5.

The improve prises two sections, the upper edges A of which at the ends run obliquely upward. when the receptacle is closed and in such position converge toward the hinges B, which connect the two sections. Theends O of the sections are provided with meeting edges C, V which are vertical when the receptacle is closed and which form acute angles with the u per edges A. The side D and the bottom E of each section, as shown, are formed in one piece of sheet metal suitably strengthenedby ribs F. The meeting edges E of the bottoms extend horizontally, and the u per edges I) of the sides are preferabl also orizon'tal. At suitable ,pomts of t e ends I), near the upper edges thereof, chains G or other suspending devices are detachably secured to the receptacle-sections. The points of attachment should be so located that when the receptacle is closed the vertical lines drawnthrough the centers of gravity of each section will ass outside the attaching-points G. Thus t e weig'nt bf the sections, as well as the weight of the material contained in the receptacle, will tend to keep the receptacle closed. The manner of supporting t e Specification of Letters Patent.

receptacle is immaterial to 'my invention. In the drawings I have shown a beam H, to

which the chains G are attached, said beam being suspended by means oi-a cable I and pulley I from the swinging arm J of a derrick, the cable I serving to hoist the receptacle and lower it, another cable K serving to' raise or lower the arm J, while a third cable L serves to turn the ost M, to which the-arm 5 J is pivoted at J. t each end of theirecep tacle I prefer to arrange a latching device, consisting of a latch N, pivoted at N to one section, and a keeper 0, secured to the other a section and adapted to receive the end or hook of said latch. Each-latch is connected with a ro e or Wire P, passing through a suitable gui e C at the outer portion of the respective end C, and each rope P is detachably I connectedwith a rope P, attached to a ro e P and passing over a pulley Q toa suitab e securing device or cleat M on the post M.-

The operation is as follows: The receptacle being in the condition illustrated by Fig. 1, the material is loaded into the same through 30 the open top. It is not necessary that the receptacle be connected with the derrick during the loading 0 oration, as the receptacle might be loade at one place and then brought under the derrick by a car or other 5 conveyance and thereupon attached to the derrick. Then the receptacle is raised by a pull on the cable I, and the post M is swung by means of the cable L until the rece tacle is above thev intended point of disc arge.

The wires or ropesP are secured to the cleat M in such a manner as to cause the rece tacle to be vunlatched and to open at t e pro er point as the receptacle is lowered. It

wil be understood that the ropes P P P are at first slack; but when the receptacle has descended to a predetermined oint such.

rther descent of the receptacle will cause the latches N to be lifted from the keepers O, and then as the latches are swung against stops R the ull or resistance of the ropes P will be transferred to the guides C and thus gravity.

will cause the receptacle to open, as :illus-" trated in Figs. 2 and 3, it being understood that the gu des C are located exteriorly of the vertical lines passing through the centers of gravity of the two sections. After dis-..

charge the receptacle is raised again and will close automatically. 2 m

The latches N are used for the sake of safety only and may be dispensed with, if dei 4 sired, in which case the ropes P would be receptacle-sectionsfor instance,

simply secured at the outer portions of the at the points indicated by the guides The fact that the upper edges A of the ends C form acute angles with the vertical i ee ting edges Cis of considerable advantage as regards facilitating the discharge of the mateoverhang above the open top of the receptacle, 'such projecting material will drop into,

and through the rece tacle as the top open ing becomes enlarge during the discharge operation. The operation of the dumpingreceptacle is thus rendered more reliable, and danger to attendants is minimized, as there is less likelihood of projecting material falling on the outside of the receptacleduring discharge and causing accidents.-

Instead of having the rope Pattached to the cleat M, I may (as shown in Figs. 5 and 6) pass it under a pulley Q and fasten its end to a double pulley R provided with a rope S, and wei 'ht T, so arran ed as to keep the ropes P P taut, yet allow them to be paid out until the rope P has been unwound fully, As soonas this happens the latches N Will be released. 'The time at which the unlatching Will bccur is governed by the number of turns of'the rope P originally wound on the pulley or drum B. Other means may be employed for operating the latches at the proper moment. fl

I claim as my invntion- 1. A dumping-receptacle comprisingtwo open-top sections hinged together at their meetin portions, the hinge-joint being located a ove the bpen top of said sections in the closed position of the receptacle, individ ual suspending means attached to each of the sections at a distance from the hinge, yetwithin the vertical lines drawn through the centers of gravity of, said sections, an opening device one end of which is arranged to exert a pull onthe outer portions of said sections,-

exteriorly of the said vertical lines, andmeans for adjustably fasteningbthe other end of saidppening device to varia time of opening the sections.

sections-,-in combination with a flexib eopenly govern the ing device connected with the outer portions ofsaidsections, and means for adjustably fastening the 0th rend of the said device to variably govern e time of opening the sec.

tions.

3. A dumping-receptacle comprising hinged sections, in combination with. a boom, a suspending device'extending from the boom to the receptacle, a flexible opening device conmated with the outer portions of said sec tions, a guide on the boom, engaged by said opening device, and means for-varying the operative length of said device.

In testimony whereof I have hereunto signed my name inthe presence of two sub-- scribing witnesses.
