PORTABLE CEMENT MIXING DEVICE Filed Nov. 14, 1956 INVENTOR TYLER J. GLEASON BY WWW ATTORNEY:
United States Patent PORTABLE CEMENT MIXING DEVICE Tyler J. Gleason, Chatham, N. Y.
Application November 14, 1956, Serial No. 622,132
7 Claims. (Cl. 259-177) This invention relates to a portable cement mixing device and, more particularly, to a wheelbarrow mounted mixing device having a motor to drive the mixer.
An object of the invention is to provide a wheelbarrow mounted mixer so that the ingredients of the mortar or concrete may be placed in the barrow at the place of storage, and may be easily moved to the point at which the material is to be used.
A further object is to provide a concrete mixing device of great simplicity so as to be inexpensive to manufacture and inexpensive to maintain.
Mortar mixed at ground level, for example, and carried up to masons working high in a building is not, especially at the end of the batch, in proper condition for use and wastage often occurs as a result.
A still further object, therefore, is to provide a mixer which will eliminate the time lag between mixing and the use of concrete or mortar where the place of use is remote from the street level, where the concrete under present practice is mixed in a standard concrete mixer and delivered by wheelbarrow after mixing, or where it is necessary to work without the usual dirtying of the premises due to hand carrying ready-mixed concrete.
Other and further objects and advantages will appear from the following specification taken with the accompanying drawing in which like characters of reference refer to similar parts in the several views and in which:
Fig. l is an elevation of one exemplification of the device;
Fig. 2 is a top view of the device looking in a direction normal to the section line 33 of Fig. 1;
Fig. 3 is a view along section line 33 of Fig. 1 and looking in the direction of the arrows; and
Fig. 4 is a plan view of a frame for the device.
As seen in Fig. 1, the wheelbarrow portion of the structure is made up of handles and wheel 11 mounted at the forward end of the handles by bearings 12. Appropriate cross-bracing 13 is provided in front of the wheel 11. Legs 14 and braces 15 complete the wheelbarrow structure per se.
Mounted on this wheelbarrow structure is a frame which is shown in Figs. 1 and 4 as being made of angle iron. Mounted on the longitudinal frame elements 16 are support rollers 17, and mounted centrally on cross frame elements 18 are grooved retainer rollers 19.
A motor 20, carrying a driving pulley 21, is mounted below the frame on a support 22.
A carrying and mixing barrel 23, having axially ex tending chimes 24, is placed on support rollers 17 with the chimes 24 running in the groove of retainer rollers 19. Rollers 17 and 19 may be of rubber, or rubber covered. It will be understood that since the chimes 24 are engaged in the grooves of retainer rollers 19 that the barrel 23 may rotate with respect to the frame but cannot be separated from the frame. Support rollers 17, of course, normally support the weight of barrel 23 and its contents.
2,837,321 Patented June 3, 1958 ribs 25 of any appropriate design, and with a filling and pouring spout 26 at the forward end of barrel 23 as it is mounted on the wheelbarrow.
As seen in Fig. 1, the frame, with barrel 23 thereon, is mounted on the wheelbarrow structure so that when at rest the spout 26 is somewhat elevated. The angle of the frame and barrel with the wheelbarrow must, of course, be such that, with a load of mortar in the barrel, it will not overflow when the barrow is wheeled to move it from place to place.
The mixing of mortar, concrete, or other material in barrel 23 is performed by rotating the barrel on the frame. This is done by motor 20 driving, in the exemplification shown, a belt 27 that embraces barrel 23, by way of a jack shaft 28 on which are mounted a pulley 29 driven from pulley 21 on motor 20 and a pulley 30 driving belt 27. Jack shaft 28 is supported at the rearward end by a bearing 31 mounted on brace 15 and at the forward end by a similar bearing 31' mounted on a cross brace 32 behind wheel 11.
It will be seen that belt 27 could drive barrel 23 directly from pulley 21, but the indirect drive is preferred as giving a slower rotation to the barrel 23. Other speed reducing means could, of course, be used to drive barrel 23 from motor 20 and sprockets and chains could be substituted for the belts shown if desired.
It will be seen, then, that the barrel 23, Fig. 1, may be filled with the necessary ingredients and wheeled to the location of desired use where the motor 20 may be plugged in to an appropriate power source and the ingredients will be mixed. Of course, the mixing may be done prior to moving the barrow to the location of use for the material, or during transportation if desirable. The contents of the mixing barrel 23 may be readily discharged by raising handles 10 to approximately vertical In any case it will be noted that spout 26 is sufficiently long so that when pouring mixed material from barrel 23 the material will fall beyond the brace 13. A cover or guard, however, may be placed over the forward end of the barrow so that any spillage could be easily removed and wheel 11 could be kept clean.
While a simple specific exemplification of a device of my invention has been described above and shown in the drawings, it will be understood that the scope of my invention is to be construed to fall within the scope of the appended claims.
Having described my invention, what I claim as new and desire to secure by Letters Patent is:
1. In a wheelbarrow mounted mixer, a rotary mixing barrel having a chime at each end edge, and a concentric discharge spout at one end, a pair of support rollers carried by said barrow to rotatably support said mixing barrel, at least one grooved roller on said barrow at each end of said mixing barrel so placed as to receive the outer side edge of each barrel chime in its groove, the grooves of said rollers being disposed in opposed spaced relation to each other securely to hold the barrel rotatively between opposite chimes, whereby said barrel is held in position on said support rollers, and against end- Wise movement in both directions as well as against upward movement away from said support rollers upon- 3. The device of claim 2, in which said means driven 3 by said motor is a belt extending around said barrel and 7. The device of claim 1 in which said support rollers around a motor driven pulley. are in the form of elongated cylinders.
4. The device of claim 1, in which said barrow is provided with said wheel at the end of said barrow under References Cited In the file of this Pawnt said discharge spout, said spout being so placed that, as the barrow is tilted on said wheel, material discharged UNITED STATES PATENTS from said discharge spout will clear said wheel. X 2 maenp las u g 5. The device of claim 1, in which the axis of said K y D 1948 barrel and of said barrow lie in the same plane and the 3 amper axis of said barrel normally is at such an angle to the 10 FOREIGN PATENTS horizontal as to retain material in said barrel.
6. The device of claim 1 in which said discharge spout 27 3,001 Germany p 1914 is frusto-conical in configuration. Y
