CONVEYING AND mx'me MACHINE.

Application filed May 19, 1906. Serial No. 317,725.

To: all whom it may concern:

Be it known that I,'Lnw1s K. DAv1s, a citizen of the United States, and a resident of the city oiNew York, in the county of New York and State of New York,

United States of America, have invented certain new and useful Improvements 'in' Conveying and Mixing Apparatus, of which the following is a specification.

My. invention relates t9 an apparatus for conveying and mixing material, and-its object is to provide a simple and efiicient arrangement of parts for convey.-

gether with some of its connected parts. Fig. 2 is a V side elevation of some of the parts shown in Fig. l,

the view being taken at right angles to that shown in Figs. 1. ,'Fig. 3 is aplan view'of some of the parts shown in Fig.1 and 2. Fig. 4 showsin side elevation a modification of my invention. Fig.1 5 is an enlarged detail view of a device which I use in carrying out my invention;

Like characters of reference designate corresponding parts in allol' the figures.

10 designates a hoisting engine which is arranged to rotate a winding drum 11 to which a ropeor cable 12 I is attached. 'This rope or cable 12 passes over suitable guiding or supporting pulleys 13, 13, and its other end is attached to a traveling frame 20. This frame 20-is arranged to travel upon and be supported by station'- ary guides 21, 21 which, in the present instance, are

shown in a vertical position, but which may be horizontal or inclined if desired. The traveling frame 20 comprises bearings 22, 22

l which support trunnions 23 and 24 which are .attached -to a rotatable receptacle 25. This receptacle may be of any desired form or construction; for" example, it may be a box in the form of a closed cylinder, or it may be rectangular in form. It is provided with a door 26 over an opening in-one portion of its outer surface. The shaft or trunnion 24 extends through one of the bearings 22-, 22 and has connected to it a sprocketwheel 30. This sprocket-wheel may be directly attached to the shaft or trunnion 24, but I prefer-to mount it'loosely upon this shaft as shown in Fig. 5, and to connect it to the shaft 24 through a clutch 31 which may be normally held-in its closed position by aspring 32, and which may be. released by means of a lever 33', which is-pivoted at 34 to a bracket 35 which is at tachod to a portion of the traveling frame 20.

40 designates-a sprocket-chain which is attached at 41 to a suitable iastening near one end of the travel of .55 {he movable frame 20, and which extends up through' out the length of the travel of the movable frame to supporting pulley 42 and down to a weight 43 to which its other end is attached. I

It may be seen that the fastening 41 and the supporting pulley 42 are placed to one side of the path of travel of the sprocket-wheel 30. The weight 43 maintains a tension on the sprocket-chain 4.0 and causes it to be held in engagement with the sprocket-wheel 30.

At 50, in Figs. and 2, a hopper is shown which may be pivotally attached, as shown at 5l,"to one of the guides 21', or to some other part of the supporting structure. designates another hopper similarly pivoted In the operation of this device the material to be con veyed and mixed may befirs'tplaced in the hopper 50, and when the traveling frame 20 is near the lower end of its travel, this hopper 50 may be swung around its pivots until its mouth 52 is directly over the door 26 in the receptacle 25. When in this position the door 26 over the opening may be opened; then the hopper is opened tacle 25. If the door 26 in the receptacle 25 does not register with the mouth 52 of the hopper 50, the clutch.

. 7 5 and may be allowed to discharge its lead into the recep- 31 may be released-and the receptacle, turned around until the door 26 and the opening which it closes is directly above the mouth of the hopper. After the receptacle has thus been filled the door 26 may be closed and fastened and the engine 10 allowed to rotate its windingdrum 11 and to hoist the movable frame 20. During its travel the sprocketwheel 30, passing up over the sprocket-chain 40, will be rotated by the movement of v the traveling-frame and will thereby cause the receptacle 25 to be rotated. When the movable frame 20 and its supported parts reach the desired point it may be stopped and the receiving hopper 60 swung about its .pi'vot until it registers with the door 26 in the receptacle 25. The clutch may be released and the receptacle rotated by hand until the door 26 is at the desired point, when the door may be opened and allow the contents tobe emptied into the receiving hopper 60. The ho per 60 may then be swung back out of the way and the frame 20 may again be lowered for another load and this operation may be repeated indefinitely. The clutch '31 may, of course, be released and held out of engagement with sprocket-wheel 30 during any part of the op eration, and for this purpose a hook 36 or a rack and pawl 37 may be provided.

In Fig. 4 I have shown a modification of my invention, in which case the sprocket-Wheel 30 is supported by shaft 24* which runs in bearing 22, 22, which are supported by the movable frame 20. The receptacle 25 is inthis case supported by'the shaft or tl unnions .23 which run in bearings 22, 22 in the frame 20 These shafts 23 and 24 may be mechanically connected together by a pair of beveled, gears 29 or by any vention is used I prefer to provide the receptacle with two doors 26 maze which may be arranged the drum. 1.5

with closing doors as before described. The operation of this device is similar to that already described.

It is obvious that this invention is useful in connection'wit h the hoisting or conveying of concrete, mortar or sand during building operations, although,of course, it is not limited to this use. The receptacle 25; as I have stated, may be of any desired form. It may .be provided with inwardly projecting mixing vanes or plates 281m its inner surface to provide for the more per 7 material as they are rotated within feet mixing of the I have illustrated more than one construction of this device to show that it is capable of many modifications and I therefore donot limit myself to the precise-form of construction herein shown and described. I

It is obvious that when this deviceis used there is a great saving both of time and labor, and the power of the one engine which is used' to convey the materials is also used to mixthem together.
