Application March 8, 1946, Serial No. 652,866 Y 3 Claims.
The present invention relates to concrete compactors and more particularly to a device for compacting a cement wall.
When cement is poured, it must be carefully and thoroughly compacted or air holes or pockets will form in it around the larger stones and around the structural metal members or reinforcing bars customarily used in such constructions. When the concrete is laid on a flat surface, as in constructing a iloor, it is a relatively easy matter to compact the concrete by tamping it after it has been poured. Where the structure is vertical, as in a wall, however, such tamping is not as convenient or effective because the concrete is poured in forms and all tamping must be from above. Preferably the concrete must be tamped after every foot or so has been poured. This results not only in delay but because of the larger amount of structural support members necessary in. a wall is not too effective and holes or pockets result. Furthermore, tamping always results in uneven compacting as the side or surface that is tamped is well compacted, but the parts spaced from this side or surface do not get the full force of the tamping action and usually retain some of the airl holes or pockets initially formed therein.
An object of the present invention is to compact concrete internally by the insertion of an agitating or vibrating device Which will compact the concrete thoroughly and remove all air holes or pockets and which will act quickly so that it may be gradually raised as fast as the concrete is poured, thus eliminating the delays previously encountered.
Another object is to provide a compacting device that is electrically driven so that many compactors may be operated by one person.
Still another object is to provide a compactor that vibrates or agitates sideways from the center of the layer of concrete and hence compacts the concrete uniformly. Y
Still another object is to provide a compactor that is very long and thin so that it may be inserted and withdrawn between the metal structural members or reinforcing bars.V Another object is to provide a device adapted to compact concrete and thin semi-Huid masses which are poured into forms in planes other than horizontal.

While we have shownand described certain embodiments of our invention it is to be understood that it is capable of many modifications. Changes, therefore, in the construction and arrangement may be made without departing from the spirit and scope of the invention as disclosed in the appended claims.
In Fig. 1 of the drawings, there is shown a concrete wall shown generally at 2D being constructed in a form comprising a front wall 2| made of a single layer of boards and a similar back wall 22 on which is provided a platform 23 for the workmen. A suitable power line (not shown) supplies electric current to a plurality of leads in cables 24 each of which is connected to a compactor 25. These Compactors are suspended by the cables between the Walls of the form and as wet concrete 2.6 is poured into the form are energized to vibrate the wet concrete around them, and thereby compact the concrete by eliminating all air spaces or pockets formed therein around larger stones in the concrete and around or adjacent the customary structural metal members (not shown) embedded in the concrete. As illustrated, the Compactors are embedded in the concrete every few feet and, as the concrete rises or mounts in the forms, are adapted to be gradually raised by the workman to compagct higher parts of the wall. pactorsv being .relatively small in fdiameter, v*the concrete will ow into and fill the space formerly occupied by them as they are gradually raised; and they may be readily Worked up through .any reinforcing rods or the like in the concrete.
Figs. 2-7 of the drawings disclose ya :preferred form of compacter in which the compactor comprises a long, thin cylindrical ,casing 210i metal, plastic, rubber or other suitable materialv Which will not be affected or damaged by the wet concrete. The upper end of the casing is promised-.with .alcol-lar 2.3 adanted to receive-the end ofaca'nle .24. zllheother .end ofthe casing `is n-lied by n nlug 219 suitably secured thereto and having a central y.tl-1readed opening drilled therein to re` ceive a threaded nut 3B extending from a. .disk flzforming the `holttom el an inner cylindricalcasn ing s2. The disk 3j is threaded into .the raising 3.2 as shown #and a lock washer holds the disk .3.4 inni-ace. v
Secured abovethe disk .32 is a solenoid 34 hay .a .square .central .bere .into which extends whe lower square end 35a of a shaft 3 5, The upper end ofthe .inner casing is also .threaded internally to receive a disk 36 under which is secu-red a solenoid El, a .loch washer .3.8 holding the. disk 3B in place. The solenoid 31 also has a central cullare .bore into which the other end 35e of th shaft 35 extends. L
The Ycentral portion ci the shaft 3.5 isenlaireed, and hollowed out to .term an openingzf.. Be-
tween the central section and the square endsY sand .35o .ari-:sections 35e and 55dcf circular cross section, but of smaller diameter than theY .en-trai section. Around these sections 35e and 35d are ball bearings 39 in raceways 4i! .secure to inner easing member ..32 by means ofv threaded bolts 4i. A pair of bracketsLl?u are sen cured to `the inner wall of the casing 32 are provided with aligned openings in which is mmm-ted a stub shaft 43. A walking beam A4. is pivotally mounted on this `shaft .and .as shownin Fig. l .extends through the opening 35j inthe shaft 35. i
bolt lHalso extends through the center ofthe shaft '35 and through the Walking 'beam44 andis held. in place hy a nut d, the bolt .de being of less diameter than the openings in the shaft 35 and wailnng beam 44 through which Vthe boltv (not shown) Yleads .from these-solenoids to a return in, the cable 24. .In operation the solenoids 34 and 31 are alternately energized by the switch 48 and hence raise- `and lower the shaft 35 causing the heavy walking bea-m 44.130 oscillate back and forth on the The comv In 'the alternate constructionashown inrlligs.
8-l2, the compactor device 425 comprises an ou'ter casing 21 suspended fromV a cable 24 as in the previous figures and an inner cylindrical casing 32 which is provided with a pair of internal flanges H33. Solenoids 34 and 31 are -mounted `in eachpend of theV casing as in the previous figures and extending into the bores thereof are the square ends l35a and 1351) of a'shaft I 35. As shown, this shaft |35 has a circular central section :i350 connecting the two end sections. Surrounding the shaftsection lc is a sleeve .member -l 4having a heavy extensionorproiection ideeen .one side thereof, .cut-out portions i365 on its opposite side and aslot .lcinits centr-al portion. .Inthe slot i350 and .rotatably in. vuitedfon 1a :bolt .L31 threadedinto the vsliiaft section iddo Vis .a rol-ler i3d. .The sleeve-35 secured in position-in the casing ld2 by V.means of ball bearing assemblies it@ bolted to .a reduced end of the sleeve .and with their outer race members pressed-into thev casing i 312 andagainst .the tia-egcs -I 3d. r.Phe electrical-connection the saineas that 'of 2 7 inclusive.

.In Figs. 13.110 1,5, still another compacter de vice construction 225 is disclosed comprising an outer casi-ng 221 in the upper part-of vwinch is mounted -a small electric motoring, the shaft 2M of which is `enlarged at 2Mow-here itis journaled in ball bearings 2st mounted in .a sleeve 1284 threaded to the .lower vend o the casing of the motor and Aspaced .therefrom .by a washer 235'. A sleeve Aimpressed in the upper end .of the .housing 2.1 .is threadedly secured to the upper end of the .motor which is also held in place by washer 231 and a nut 298 likewise threaded. into the sleeve .2.65. A lead .25a from a cable 2s is connested tothe motor. Y
