POWER-CHARGING ImvIcE 1m coN'cRETE-MIxnR-s.

To all whom it 'rria'y'concern: I

Be it known that I, Annular E. SMITH, a

State of Wisconsin, have invented a new and useful Power Charging Device for C011 (mete-Mixers, of which the following is a description, reference being had to the ate'ompanying drawings, which form part of this specification.

- My invention relates to a power charging device for concrete mixers of that class termed batch mixers,- in which, a definite batch of the ingredients to be mixed is putin the mixing machinewhere it is mixed and discharged therefrom-before another batch is introduced; and the objects of my invention are to provide a durable dev1ce, comparatively simple lDJCODSiZIftlChlOIl, with very 'little overhang over theside of, the

truck, and lastly one in which the hoisting rope has a fair lead and-does notpull at lisadv'antageous angles to the support-s and the load. I attain these obj ects by the mechanismillustrated inthe accompanying drawing, in which, I v Figure 1 is an end view of a mixing machine with the power loading-1 device atta'ched, the loading bucket being shown in full lines in its lower position, and 'in dotted lines in its ,elevatedposition -'Fig. 2 is a view of the machine-as seen by looking at Fig. 1 from the right-hand side thereof.

Similar letters refer vto similar parts throughout the different views of the draw-- in n.

a I I u o I A concrete mixer is shown in the drawlng mixer may be used, it Willxbe sufficient description to say that A is a cylindrical drum of a non-tilting mixer.

B 13 are roller tracks engaged by the rollers C C, by' which the drum is supported. The frame D affords journal bearingsfor the rollers, and is also utilized for attaching the charging device. p E E are the track timbers, F one of the axles and F one of the truck wheels on which the. entire machine istransportable.

The charging bucket G is provided'wit-h a long spout G which ispivoted to the frame H in front of the feed opening of'the drum II. by means of the shaft 7r attached to-the frame H and the box or bearing'h attached As any concretese iai'no. 463,205.

to the spoutG'," The frame H is secured to the frame D by bolts at the point It". The lower partsof the-frame H are vertical but the upper partsmay be bent toward each other, and at. their junction they support an inclined shaft K carrying the inclined sheave Z. left side of the mixer by, means of the rods in, connected to the upper corners of two frames consisting of uprights m," and struts 972"."

The boom I is-pivoted to the frame H by means of the castin' s L- and pivot pins passing therethrough. he two upper portions of the boom -members are bent toward eacli'other and at the upper end support the sheave nwhich runs loose on its shaft. The hoomI is attached to the frame H by thelinks 00 which have .a pin and slot engagement with each other.' These links limit the outward-swingeof the boom I and as theboom swings in toward the frame H the links fold downward. The sheave p is connected to the bucket G as shown, and the guide-sheave g is attached to the frame H by the bracket g. 7

Any kind of hoisting apparatus maybe used, R being the drum. The hoisting r0 e is attached to the boom I by means of'tie' The frame H is tied tothe VVhile' the bubket-G is being elevated,'thefl. boom will. at first remain in its extended or outward position', on account of the rope being'attached' thereto at p. When thespout G strikes the bar 1 the boom commences-to swing toward the frame H and finally they bucket and boom arebrought to the position shown in dotted lines in Fig. 1.

While the drawing shows the sheave Z on; the right handside of the mixer, I-consider .it withinthe scope of my invention to place this sheave and the extensions of the frame. 1

above the cross bar m on the other side of 0 the machine. Also the shaftof the hoisting device maybe-placed crosswise of the machine parallel to the axles of thetruck,

' ..What-I claim as my invention, and desire to secure l y Letters Patent, is-v 1. A power charging device for concrete mixers, comprising a framework extending upward fromthe mixer .frame', a loading framework withit-snose in position to enter the mixer drum, while the bucket is resting bucket having a long spout pivoted to said onthe ground, a swinging boom hinged to said framework, means limiting the outward swing of said boorma hoisting device on the mixer, sheaves on the budget and on the up per ends of the boom and. frame, a hoisting rope connected to the boom near its upper end, leading under the sheave on the bucket,

' over the two upper sheaves and thence to the hoisting device.

2. A power charging device for concrete mixers, comprising a frame on the mixer, a boomhinged on the frame, a bucket with a long spout hinged to the frame, a hoisting device and a hoisting rope attached to the upper end of the boom and passing under a sheave on the bucket, over sheaves on the up per partpf the boom and the frame, and to the hoisting device.

3. A power charging device for concrete mixers, comprising a loading. bucket, a hinged or swinging boom, a hoisting device, a frame Work on the mixer, and a rope attached to the upper end of the boom, leading around sheaves on the bucket, the upper part ofthe boom and of the f ame to the hoisting device.

i. In a power charging device. for concrete mixers, a boom hinged at its lower end, means limiting the outward swing of the boom, a loading bucket provided With a-' sheave, means guiding the discharge end of the bucket and a hoisting rope attached to the boom and leading around the sheave on the bucket and over a sheave on the boom.
