UNITED srA CONCRETE MIXER.
Application filed April ,6, 1929. Serial No. 353,053.
This invention relates to a concrete mixer and has for its primary object to provide, in a manner as hereinafter set forth, a concrete mixer wherein the mixing drum may be selectively positioned to deliver its charge on opposite sides of the support for the mixer and to receive its charge on the opposite side of the support from which the charge is delivered.
A further object of the invention is to provide, in a manner as hereinafter set forth, a concrete mixer as aforesaid, wherein the contents of the mixing drum may be selectively discharged therefrom in opposite directions without the necessity of changing the position of the support for the mixer.
Vith the foregoing and other objects in view, the invention consists of the novel con struction, combination and arrangement of parts as hereinafter more particularly described, and as illustrated in the accompany ing drawings, wherein is shown an embodiment of the invention, but it is to be understood that such description and drawings are to be taken as illustrative and that the invention is intended to be limited only by the scope of the claims hereunto appended In the accompanying drawings in which like numerals are employed to designate like parts throughout the same:
Figure 1 is an elevation of a concrete mixer in accordance with this invention.
Figure 2 is a fragmentary sectional plan thereof.
Figure 3 is a fragmentary elevation show ing the tilting mechanism.
Figure 1 is a perspective view of the reversible stop element forming a part of the tilting mechanism.
Figure is an elevation of the stop element and actuating member therefor.
Referring to the drawings in detail, the numeral 1 indicates a mixing drum of conventional type having its bottom mounted, as indicated at2, on a yoke 3' to provide for axial movement of the drum with respect to the yoke. The ends of the yoke 3 are formed with oppositely disposed trunnions 4 and 5 for mounting on the bearings 6 of a pair of supporting standards 7 and 8. The standard 7, is of substantially, inverted V-shape havlng a pair of legs 9 and 10 which diverge in a downward direction and which are connected together by means of a suitable brace 11. The standard 8 is formed in the same manner as the standard 7 and the description of ithe latter will also apply to the standarc 8.
ras PATENT OFFICE}.
Encircling the drum, adjacent the bottom thereof, is a bevel gear 12 which is driven by a bevel pinion 13 to provide for the rotation of the drum. The pinion 13 is mounted on a shaft 1 1 which extends through the trunnion 4L and to the outer end of which is fixedly secured a hand wheel 15 to provide for the rotation of the shaft. V
Formed on the outer end of the trunnion 5 is a reduced extension 16 0f polygonal,
contour which terminates in a reduced cylindrical stub-shaft 17. In the present embodiment the shaft 17 is illustrated as being formed integral withthe trunnion 5 and extension 7 although the shaft 17 may be a separate piece if desired. Mounted on the extension 17 is a reversiblestop element 18 which is formed adjacent one end with an opening 19 corresponding in contour to the extension 16. The elementlS is formed with an inclined face 20 at the end thereof opposite the opening 19 and is further formed with anose 21 which extends in continuation of the inclined face 20. Adjacent the inclined face 20, the element 18 is provided with a pair of oppositely disposedflanges 22 and 23. p
Mounted on the shaft 17 is an actuating block 2a which bears against the outer face of the element 18 and which is formed with a pair of inwardly extending lips 25 which are disposed in overlappingy relation to the element 18. Mounted on the shaft 17 in con tacting relation with the block 24 is a securing block 26. The contacting" faces of the blocks 24: and 26 are formed with aligned grooves 27 for the reception therein of a handle member 28 by means of which the blocks may be rotated to rock the yoke 3. A nut 29 is threaded on the outer end of the shaft 17 by means of which the blocks 24 and 26 are securely held in contacting relation adjacentthe nose 21 comes in contact with.
the leg 9 and the drum 1 will be maintained in charging or mixing position as illustrated in full lines in Figure 1. Upon movement of the element 18 in a counter-clockwise di rection, such movement will be arrested when the portion of the flange 23 opposite the nose 21 comes inoontact with the leg 10 and the drum 1 will be maintained in discharge position as indicated in dotted lines and designated A.
If it is desired to discharge the contents of the drum on the opposite side of the standard, this may be accomplished byremoving the blocks 24} and 26, reversing the element 18, and replacing the blocks. With the'elementjl8 thus reversed, any movement of the element in a clock-wise direction will be arrested when the portions of the range 22 opposite the nose 21 come in contact with the legi9 and the drum will be maintained in position illustrated-in dotted lines and designated B.
It is thought that many advantages of a concrete mixer in accordance with this invention will be readily apparent, and although the preferred embodimentis asillustrated and described, yet it is to be understoodthat variouschanges in the size, shape and arrangement of parts may be resorted to, so longas such changes fall within the scope of the invention as defined inthe appended claims.
