April 9, 1963 c. GRAYBILL MIXING MACHINE AND PORTABLE DISPENSER 2 Sheets-Sheet 1 Filed Oct. 22, 1958 CLINTON LIGRAYBILL INVENTOR.
April 9, 1963 c. GRAYBILL MIXING MACHINE AND PORTABLE DISPENSER 2 Sheets-Sheet 2 Filed Oct. 22, 1958 CLINTON L. GRAYBILL INVENTOR Unit This invention relates to a portable power driven mixer and it is a general object of the invention to provide a simple, eilicient, practical and improved mixer adapted to handle materials such as concrete, cement, plaster or mortar or the like.
Another object of the present invention is to provide a mixer of the character described which is flexible and convenient to use, which can be easily transported and maneuvered in the manner of a Wheelbarrow and is convenient to load and unload when in operation.
A further object of the invention is to provide a power driven mixer of the type referred to including a simple, practical, improved arrangement and mounting of the power unit in such a manner that it contributes to the proper balance of the machine and is adjustably carried by frame elements supporting other parts of the machine, and wherein the drive between the power unit and the mixing hopper is readily adjustable to accommodate either an electric motor or an air-cooled internal combustion engine as the power unit.
A still further object of the invention is to provide the hopper with concrete mixing blades and in addition thereto a special slip-on blade attachment for mixing mortar or plaster.
The foregoing and other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawing forming a part hereof, wherein like numerals refer to like parts throughout, and in which:
FIGURE 1 is a side elevational view of a portable power driven mixing and dispensing machine made in accordance with my invention.
FIGURE 2 is a top plan view of FIGURE 1 with the power unit, power transmission means and belt drive removed therefrom.
FIGURE 3 is a side elevational detail view showing an electric motor operatively connected to the power transmission means instead of the internal combustion engine shown in FIGURE 1.
FIGURE 4 is a sectional detail end view taken approximately along the line 44 of FIGURE 3 with the power transmission means removed.
FIGURE 5 is an end view of the power transmission means of FIGURE 1 taken approximately along the line 55 of FIGURE 1.
FIGURE 6 is a view on a reduced scale of the open end of the hopper with fragments broken away and showing concrete mixing blades and a mortar or plaster mixing unit operatively disposed on the interior of the mixing hopper.
FIGURE 7 is a plan view of the mortar or plaster mixing unit shown in FIGURE 6.
With continuing reference to the drawings, wherein like references of character designate like parts throughout the several views, the numeral 1 indicates generally a chassis comprising two longitudinal members 3 turned downwardly and rearwardly at their forward end and provided with a supporting wheel 4 and a dispensing chute 5. The chassis members extend rearwardly and downwardly as at 6, upwardly and inwardly as at 7 to provide supporting feet 8, then diverge rearwardly, upwardly to provide two arms 9 and 10. The outer ends of these arms are secured as at 11 to handle-bars 12 whose forward ends are secured as at 13 to the chassis members 2 and 3 and whose opposite ends terminate in handgrips 14.
Welded to the chassis members 2 and 3 between the inner end of the arm portions 9 and 10 and braced relative thereto as at 15 is a sleeve bearing 16 through which is journaled a stub shaft 17 Whose forward end extend-s through and is welded to the base 18 of a rotatable mixing hopper 19. By this arrangement the chassis, hopper, and dispensing unit are readily portable and maneuverable by means of the supporting wheel 4.
Arranged above the mixing hopper is a frame comprising two tubular members 20 and 21 permanently interconnected by a base plate 22 secured thereto by welding or the like as at 23 and 24. The members 20 and 21 diverge rearwardly and downwardly from the base plate as at 25 and their rear ends are permanently secured by welding or the like as at 26 to the arms 9 and 10 near the outermost ends thereof.
Adapted for adjustable mounting upon the base plate 22 is an auxiliary frame indicated generally at 28 comprising a length of steel rod or tubing forming into two parallel base portions 29 and 30 bent upwardly as at 31 and 32 then inwardly and downwardly as at 33 to provide a mounting bracket 34 for power transmission means indicated generally at 3'5, and a clamping plate 36 lockable to the bracket 34 by means of bolts 37 extending through the clamping plate and into a boss 38 on a circular supporting plate 39 (FIG. 1) for the housing or gear box 40 of the power transmission means 35. The gear box is provided with a backing plate 41 extended as at 42 (FIG. 5) to match the circular supporting plate 39. The gear box by means of its extended backing plate may be adjustably secured to the support ing plate by means of bolts 45 extending through arcuate slots 46 in the extension 42, through the supporting plate 39 and provided with nuts 47 by means of which the gear box may be locked in any adjusted position relative to the supporting plate.
Journaled within the gear box 40* as at 50 and extending outwardly therefrom is a power take-off shaft 51 provided on its outer end with a driving pulley 52 and on its inner end with a gear 53 and enmeshed with and driven by a gear 54 secured to one end of a shaft 55 also journaled in the gear box 40 and extending outwardly from the opposite side thereof. The outer end of the shaft 55 extends through the clamping plate 36 and is provided with a clutch member 56 for cooperation with a companion clutch member 57 secured to the drive shaft 58 of an internal combustion engine indicated generally at 59 mounted upon the auxiliary frame 28.
Entrained about the driving pulley 52 and about the rearward end of the hopper 19 is a belt 60 for rotating the drum by either form of prime mover shown mounted upon the auxiliary frame 28.
As best shown in FIGURE 2, the parallel portions 29 and 30 of the auxiliary frame 28 are welded to transverse plates and 66, the latter of which is provided with slots 67 by means of which the auxiliary frame and either form of prime mover mounted thereon may be locked to the base plate 22 in laterally adjusted positions relative thereto by the locking bolts 67A.
It will be noted in FIGURE 3, where the clutch member 57A is shown secured to the power output shaft 68 of a prime mover in the form of an electric motor 71), that the center of the motor shaft is in a lower position relative to the auxiliary frame 28 than the crank shaft 58 of the internal combustion engine 59. By means of the clamping plate 36 and the supporting plate 39 of the transmission means, the same may be readily adjusted vertically relative to the bracket 34 to align the clutch 3 member 56 for operative engagement with the companion clutch member 57 or 57A.
As best shown in FIGURE 6, a U-shaped member 75 is secured to the forward end of the stub shaft 17 within the hopper 19 near the bottom closed end thereof. Concrete mixing blades '76 are Welded, or otherwise secured, to the leg portions 77 of the U-shaped member and rotate as a unit with the hopper.
A special mortar and plaster mixing unit indicated generally at 88 is provided for convenient placement within or removal from the hopper 19. This unit comprises a mixing blade 81 welded, or otherwise secured, at one of its ends to a substantially right angular base member 82 and reinforced by a diagonal brace 83 secured at one of its ends to the base member and at its opposite end to the mixing blade intermediate its ends as at 84. The base member is made of angle iron with one flange 82A extending downwardly toward the bottom 18 of the hopper. The mixing blade is further reinforced and stabilized by a second diagonal brace 85 secured by welding 86 to the mixing blade 81 as shown. The opposite end of the mixing blade and that of the brace 85 is each provided with supporting arms 88 adapted for telescopic engagement within the tubular frame members 20 and 21 located above the hopper. The free end of the base member 82 of the mixing unit 80 is recessed inwardly as at 90 to embrace the shaft 17 between the U-shaped member 75 and the bottom 18 of the hopper for cooperating with the arms 88' in securely holding the mixing unit in a fixed operative position relative to the inside 9 wall of the hopper for efifectively mixing mortar and plaster during rotation of the hopper.
For convenience in mounting either form of prime mover upon the auxiliary frame 28, I provide a supporting plate 95 adapted to be secured to the bottom ofeither prime mover in any approved manner and formed into inverted parallel channels 96 along both of its sides and thereby adapted to engage with and be slid along the parallel members 29 and 30 of the auxiliary frame until the clutch member 57 or 57A comes into full operative engagement with the companion clutch member 56 whereupon the free end 97 of a downwardly biased detent 98, secured at its opposite end to the plate 95, will engage with the outer edge of the transverse plate 65 of the auxiliary frame. For convenience in disengaging the latch from the plate 65for removing either prime mover from the auxiliary frame, I provide a chain 99 connected at one of its ends to the outermost free end of the detent and its opposite end to the end of a handle 10!), whose opposite end may be secured as at 101 to the engine 59 or as at 182 to the forward end of the plate 95A in FIGURE 3.
While I have shown a particular form of embodiment 4' of my invention I am aware that many minor changes therein will readily suggest themselves to others skilled in the art without departing from the spirit and scope of the invention. Having thus described my invention What I claim as new and desire to protect by Letters Patent is:
A combination mixer and portable dispensing machine comprising in combination a chassis wheel-supported at its forward end, said chassis including a pair of rearwardly extending tubular frame members, a mixing hopper having a forward open end and a closed rearward end, said hopper rotatably mounted at its rearward end to the chassis, a frame secured to the chassis above the hopper and extending forwardly relative thereto, a base plate secured to said frame, an auxiliary frame bent upwardly at one of its ends, means slidably and lockably mounting the auxiliary frame upon said base plate, clamping members vertically, adjustably, and lockably carried by said upwardly bent end of the auxiliaryframe, a power take-01f shaft journaled in and extending through said clamping members, a hollow cup shaped first clutch element secured to one end of said power take-off shaft, said auxiliary frame adapted to support prime movers whose shaft centers vary in height relative to said auxiliary frame, whereby said horizontal bearing can be adjusted vertically relative to the base plate into selective alignment with said shafts of prime movers and locked relative to the base plate, a second clutch element adapted for securement to said shafts of prime movers, whereby upon interengagement of said clutch members rotation will be imparted to said power takeoif shaft, and means driven by the power take-01f shaft and entrained over said hopper for imparting rotation to the hopper.
