Application January 13, 1936, Serial No. 58,953
4 Claims.
The invention relates to a skip for concrete mixers and more especially to a dry mix selfcleaning skip.
The primary object of the invention is the provision of a skip of this character, wherein the same is of a construction to assure the dry mixing of concrete or other material and is susceptible of vertical adjustment, that is to say, will swing clockwise on an axis so as to deliver the mix to a mixer proper in the form of a drum and in the delivery the hammering of the skip to free the mix therefrom will be avoided.
Another object of the invention is the provision of a skip of this character, wherein a bladed wheel is rotatably driven therein so as to eliminate the sticking of material therein and such material is readily and easily deposited within the skip for the dry mixing of such material, the skip being of a construction to avoid any part of a wheelbarrow used to furnish the material to the mixer from coming in contact with the revolving blade, arms or paddles of the skip and uniformity of the mixed product is assured without liability of the sticking of such material tothe side walls and thedumping of such material from the skip without hammering action.
A further object of the invention is the provision of a skip of this character, which is simple in construction, readily and easily operated,
thoroughly reliable and eficient in its purpose,
positive in action, and inexpensive to manufacture and install.
'With these and other objects in view, the invention consists in the features of construction,
combination and arrangement of parts as will be hereinafter more fully described, illustrated: in the accompanying drawings, which disclose the preferred embodiment of the invention and pointed out in the claims hereunto appended.
In the accompanying drawings:
Figure 1 is a fragmentary side elevation of a mixing drum and its support showing a skip constructed in accordance with the invention applied thereto.
Figure 2 is a top plan View of the skip, a portion of the support for the mixing drum being in section.
Figure 3 is a fragmentary sectional view on the line 33 of Figure 2 looking in the direction of the arrows.
Figure 4 is a view similar to Figure 1 showing a modification.
Similar reference characters indicate corresponding parts throughout the several views in the drawings.
Referring to the drawings in detail, particularly Figures 1 to 3 inclusive, A designates generally a portion of a mixing drum of a standard construction of cement or concrete mixer and B a portion of its supporting truck which is mobile and has rising from the end of said truck next to the feed mouth in of the drum a rack or vertical frame II, it having journaled therein a shaft I2 which is horizontally disposed and forms the axle for the vertical swinging movement of a skip in the form of a mixing trough I3 having the tapered chute end l4 and a rounded bottom l5 at its opposite or rear end, the chute end l4 being equipped with bearings It; for the shaft or axle l2 and in this manner the skipis susceptible of vertical swinging movement so that when the same is in a raised position inclined toward the drum A the chute end I 4 will discharge the contents of the skip into the mouth Ill for the feeding of the material into the said drum. When the skip is in the lowered position shown by full lines in Figure 1 of the drawings the material to be mixed therein in dry state can be deposited through the open top of said skip.
Arranged within the skip at the rear end thereof is a rotatable arbor ll supporting a bladed or paddle wheel l8, the latter being fixed to the arbor which through chain and sprocket connections I9 is driven from the shaft or axle l2. The shaft or axle I2 through chain and sprocket connections 20 is operated from the power source for the mixer proper including the drum A. The wheel l8 operating within the skip will clean the walls thereof so as to eliminate the sticking of the material within the skip and thus avoid hammering of the latter for the ridding of the walls from such material as is common and thus a clean dump of the dry mixed material within the skip can be assured for deposit within the mixer proper.
Each side wall of the skip carries a hitch 2| for a lifting cable 22 which is trained over a pulley 23 in a bracket 24 on a cross piece of the frame or rack l l and this lift cable 22 is manually or mechanically actuated to raise the skip or permit the lowering thereof.
In Figure 4 of the drawings there is shown a modification wherein the axle or shaft 25 is slidably fitted for vertical movement in a slot 26 in each side upright of the rack 21 on the truck 28 of the mixer proper and this axle carries a beveled gear 29 meshing with a pinion 30 on a stud shaft 3| slidably splined in a hollow shaft 32 having driven connections 33 with a power medium, the shafts 3i and 32 being telescopically fitted with ,each other permit extension when the axle or shaft 25 is raised when the skip 34 is lifted for discharging its contents into the mouth of the drum of the mixer proper.
The rear end edge of the skip is formed with a lift 35 and interiorly of this lift are angle wheelbarrow stops 36, these functioning to prevent the wheelbarrow which delivers or furnishes the material into the skip from interfering with the wheel l8 operating interiorly of said skip While the lift 35 assures clean dumping from the wheelbarrow into the skip.
The material to be mixed in a dry state is delivered or furnished in the skip and there such material is uniformly mixed for discharge on the lifting of the skip into the drum A of the mixer proper.
The driven connections 33 rotate the drum 31 while the drum A is of the stationary type.
What is claimed is:
1. A skip of the character described comprising a trough-like body having a chute end, a shaft journaled with the body for swingingly supporting the latter, a bladed wheel rotatably arranged within the body, driven connections between the shaft and said wheel, means for raising and lowering said body, a support having a slot therein for slidably receiving the shaft, and a driving connection between said shaft and a power unit including two telescopic members splined together, one of said members being operatively connected to said shaft and adapted to move with the shaft in its travel in said slot.
2. A skip of the character described comprising a trough-like body having a chute end, and a receiving mouth and lip, a shaft journaled with the body for swingingly supporting the latter, a bladed cleaning and mixing wheel rotatably arranged within the body adjacent said mouth, driven connections between the shaft and said wheel, means for raising and lowering said body, connections with a power unit for driving said shaft, and a stop disposed within the body between the lip and the wheel and overhanging a portion of the wheel Which is disposed adjacent the lip.
3. A skip of the character described comprising a trough-like body having a chute end and a receiving end provided with a bottom and sides, a shaft for swingingly supporting the body, a bladed cleaning and mixing wheel disposed within the receiving end of the body and having its blades arranged for scraping the mix from the walls and bottom of the receiving end, means for rotating the wheel, the edges of said blades which scrape the bottom of the receiving end of the body being parallel to the axis of the wheel, whereby the scraped material will be swept forwardly in a straight line, and means for raising and lowering the body.
4. A skip of the character described comprising a trough-like body having a chute end, a shaft journaled with the body for swingingly supporting the latter, means for raising and lowering said body, a support having a slot therein for slidably receiving the shaft, and a driving connection between said shaft and a power unit including two telescopic members splined together, one of said members being operatively connected to said shaft and adapted to move with the shaft in its travel in said slot.
