It consists of the ombinations. constnuctionszandarrangement oilparts;ashore inaiter described and claimed.
:It is a welleknown tact-that mortar, 23,5 .nsed by bricklayers, willrset, if it is allowed to An object ofmy'iinvention is: to 'provide :a mortarmixi-ng piece of equipment, which is designed to provide a convenient and continuous method of mixing the mortar, keepingthe mix alive during long periods of usageon-slowwork.
Although I refer to the mixing of :mortar, it will be apparent as the specification proceeds that plaster, cement, and other plastic materials may be mixed and tumbled inmy equipment.
"More specificallydescribedfil propose to rotate a =mort'arcarry-ing bucket continuously :for the purpose of keeping alive the supply ofmoritar. One, or more, additional-buckets are provided so that the bricklayer, or vbricklayers, the mortar to the job. Thustnese buckets-may be "easily cieaned after the work-has been-completed. The main part of the equipment, including a rotatable drum, is kept free of mortar.
Other objects and advantages will appear as the specification continues. The novel features of the invention will be pointed out in the appended claim.
Drawings For a better understanding of the invention, reference should be had to the accompanying drawings, forming part of this application, in which:
Figure l is a side elevational view of my mortar mixer and tumbler;
Figure 2 is a front elevational view thereof;
Figure 3 is a longitudinal sectional view taken along the plane IIIIII of Figure 2;
Figure 4 is a transverse sectional view taken along the line IV-IV of Figure 3 with the resilient ring being shown in elevation; and
Figure 5 is a perspective view of a smaller bucket used for carrying the mortar to the job.
While I have shown only the preferred form of my invention, it should be understood that various changes, or modifications, may be made within the scope of the annexed claim without departing from the spirit thereof.
Detailed description As shown in the drawings, I provide a supporting frame-designated generally at A. It includes a base Ill having pairs of upright front and rear standards H and 12, respectively, rising from opposite ends thereof. Idler wheels H are 1'0- ing 13. 2G
taztably married-by the upper :ends of the trout standards.
It w ill'be noted that a idrnm'B ha's:itsitorward section supported tby the wheels IN. .This drum hasits' axis 15 mounted :on an-. lncline. "Iitreidnum defines an inclined annularwall "ifis arrd abottom wall n. The rrontzofsthe :drum-is opened, iasat I 8. concave convexrib 4:9 extendsvzcircumierential ly around thesdrum wall it. (in the inside of =drum, I provide iatresilient ring 122E, which is fitted into the :anndl'argroove -21 defined :by
the concaved side of :the rib. This ring 'tumswith the drum and is "secured thereto i-n cmyssuitable manner.
'For ther purpose air-supporting the rear se'ction of the I provide a' stub shaft 322, which is fixed to the bottom wall 11. is journaled in a centrally-disposed inclined :bear- The latter is married by :a transverse member 2A fixedto the rear pair of standards i2. Thusthe wheels M and the :s'h'ai t 2 2 support the drum B f-or rotation around its inclined :ax'rs 15 (see Figures 1 and 3).
Rotary motion is imparted to the shaft 22 so as to rotate the drum B. This is accomplished by a motor 25, which is operatively connected by a belt drive 26 to a speed reduction unit 0, the latter being connected by a belt drive 21 to a pulley 28. The latter is fixed to the shaft 22. Of course, other suitable means may be employed for tumins the drum B.
It will be found convenient to mount the motor 25 on a platform 29, which is secured to upper inclined sections [2a of the rear pair of upright standards l2 (see Figure 1). I have shown the speed reduction unit C as being carried by a yielding platform 30, which is anchored at its rear section by screws 3| to the standards l2. The forward section of the platform 30 may be adjusted by a turnbuckle 32 so as to place the proper tension on the drive belts 26-21. This turnbuckle is anchored to a plate 33, which is fixed to the base I0 of the supporting frame.
In actual practice, the drum should be turned at about ten revolutions per minute. However,
I do not desire to be limited in this respect.
Figures 1 to 4, inclusive, disclose a mortarca-rrying bucket D, which is removably telescoped into the drum B, with its longitudinal axis 34 arnecessary in the bucket, the mixing being accomplished by the tumbling action of the mortar.
Jack screws 39 are provided on'the base H],-
with their feet 40 resting on the underlying surface 4|.
axes I5 and 34, respectively.
These screws maybe adjusted so as to change the inclination of the drum and bucket Referring now to Figures 3 and 4, I show the 4 bucket D as being rotated in the direction of the arrow 42. '-The upper part of the mortar at the lower section 43 of the bucket will be picked up by the interior peripheral wall of the bucket and carried upwardly, finally tumbling back as suggested 'by the arrow 44 into the other mortar.
As the mortar is elevated from the lower section 43 of the bucket, other mortar will gravitate downwardly from the higher section 45 of the bucket to the lower section, as suggested by the arrow 46 in Figure 3. Thus the mortar is tumbled constantly while the drum B is turned, keeping the mortar "alive and ready for instant use.
The bricklayer may be provided with a smaller bucket D, as shown in Figure 5, for carrying a supply of mortar E tothe job. Of course, the remainder of the mortar remains in the larger bucket D and constantly is kept ready for use by the bricklayer.
Accordingly, when the equipment is closed down, only the larger and smaller buckets D and B, respectively, must be cleaned. Figure 3 discloses the upper end of the bucket D extending beyond the top end of the drum B. This will prevent any mortar from falling into the interior of the drum.
The entire unit requires a relatively small storage space, since the buckets may be nested one within the other and placed in the drum.
It will be found convenient to use two fivegallon or other suitable size buckets. While one is being used by the workman, the other may be disposed'in'the mixer. In the event that the mortar (or other material) starts to harden in the workmans bucket, the latter may be placed back in the machine for a short time for mixing the mortar again.
I claim: v I
In combination: a drum mounted for rotation around an inclined axis; the drum including an inclined annular wall; an annular resilient ring extending around and fixed relative to the interior surface of the inclined drum wall; means for 'rotating-:the;drum; and a mortar-carrying bucket removably disposed in thedrum, and having itslongitudinal axis substantially paralleling the inclined axis of thedrum; the bucket having an inclined annular ,wall riding on the annular ring so that the bucket will be rotated when the drum and its resilient ring are turned;
