CEMENT SLAB FINISHING DEVICE Filed April 5, 1961 INVENTORS A NDREM/ K ELL. Y 4WAENcE FERRELL. JR.
HERBERT C. 5CHULZE 72 ATTORNEY United States Patent 3,090,066 CEMENT SLAB FINISHHNG DEVICE Lawrence H. Ferrell, In, 2440 Bunche, Riverside, Calif., and Andrew Kelly, 6661 Jacaranda Ave, Fontana, Cali-f.
Fiied Apr. 3, 1961, Ser. No. 100,460 3 Claims. (Cl. -2358) This invention relates generally to cement slab smoothing devices and particularly to mechanism for automatically adjusting the angle of the finishing blade from the pole end thereof.
It is one of the main objects of the invention to provide a smoothing and finishing device for cement slabs or the like whereby the operator may by manual rotation of the pole handle quickly adjust the blade to any desired angle of approach.
It is customary when cement or like material has been poured from a conventional mixer into a slab area that smoothing of same be accomplished by vigorous manually propelled blade action before the cement has set. The physical attack on the initially dumped cement and smoothing thereafter requires so many degrees of pole and blade adjustment that constant manual adjustment at the blade end of the device not only becomes a nuisance but also requires withdrawal of the device from the slab.
The theory of the present invention is based upon manual outer pole rotational movement to quickly and automatically adjust the smoothing blade angle with respect to the manually reciprocated elongated pole. It is necessary to constantly vary either the smoothing blade angle or to move the operating pole to comfortably manual position.
Another object of the invention is ot provide an adjustable connection between a cement smoothing blade and an operating handle whereby rotational movement of the pole from a remote position either releases or tightens the pole in desired angular position with the blade.
Yet another object of the invention lies in the provision of a pole that is pivotally connected to a finishing blade and angularly adjustable therewith by manual rotational movement.
Still another object of the invention is to provide a releasable connection between the pole and blade whereby manual rotation of said pole from a remote position quickly results in desired angular adjustment.
A further object of the invention is in the provision of pole actuated means for releasing the pole so that it may be moved to the desired angular position with respect to the smoothing blade and thereafter setting same firmly thereon.
Other objects will appear when taken in connection with the attached drawing, in which:
FIGURE 1 is a plan view of a preferred embodiment of the device;
FIGURE 2 is a perspective view of the blade end of the device;
FIGURE 3 is an elevational view partially in section taken on the line 3-3 of FIGURE 1;
FIGURE 4 is a sectional view taken on the line 44 of FIGURE 3;
FIGURE 5 is a plan view of a modification of the pole actuated blade; and
FIGURE 6 is an elevational View taken on the line 6-6 of FIGURE 5.
Referring to the drawings, a preferred embodiment of the invention is shown in FIGURES 1 through 4. A modification or alternate disclosure of the blade is show in FIGURES 5 and 6.
A cement or other material smoothing and finishing blade or trowel is referred to as 10. The blade 10 is conventionally rectangular in shape although form is not important as far as the present invention is concerned. The blade 10 is usually formed of steel or heavy metal and may or may not be Weighted depending upon the nature of the particular job. The blade 10 is moved either reciprocally or otherwise from a remote position by an elongated manually operable pole 12 which may be constructed of wood or metal as desired.
The essence of the invention as disclosed in FIGURES 1-4 resides in the particular manner of connecting the blade 10 and the pole 12. It is essential that the connecting means or mechanism be actuated from a remote position by the operator by manual rotation of the pole in one direction or the other to either release or clamp the pole 12 in desired angular position with respect to the blade 10.
The pole 12 is reduced in diameter at 14 near its blade end and a sleeve 16 receives and surrounds this reduced portion. A collar 18 pressed or otherwise connected on the end of the pole 12. sustains the pole securely but rotatably in the sleeve 16. Dual arms or rods 20 and 22 project in an outwardly flared bifurcated manner toward a longitudinally disposed metal strip 28 bolted at 29' on the blade 10. The strip 28 has a pair of brackets 30 and 32 upstanding from either end thereof. The outer ends 34 and 36 of the rods 20 and 22, respectively, are bent laterally to engage apertures 38 and 40, respectively, in the brackets or cars 30 and 32. The connection is pivotal and the pole 12 may be moved angularly with respect to the smoothing blade 10. An arcuately shaped metal rod 42 is pivotally connected in an integral base riveted or welded at 46 on the upper surface of the blade 10 and rearwardly of the strip 28. An angle iron cross piece 48 is welded at 50 and 52 to the rods 20 and 22, respectively, intermediate their length. The cross piece 48 is apertured at 54 to receive the rod 42 and slide thereon as the pole 12 is moved manually with respect to the blade 10. An eye 56 extending through the cross piece 43 slidingly encircles the rod 42 and is either welded to or securely connected to a threaded nut 58 welded at 60 to the angle iron cross piece 48. A threaded bolt 62 is embedded, in or fixedly connected to the blade end of the pole 12. Ihe exteriorally threaded end 64 of the bolt 62 is received in the nut 58 and passing therethrough may or may not have clamped engagement with the rod 42 depending on the direction of rotational movement of the pole 12.
The operation of the embodiment of the invention as herein described is simple. The operator from a remote position with respect to the cement slab to be smoothed may by manual rotation of the pole 12 release the bolt 62 on the arcuate rod 42. Thereafter, any desired degree of angle adjustment of the blade 10 and the pole 12 may be accomplished quickly and automatically without withdrawal of the device from operative position.
The alternate disclosure as shown in FIGURES 5 and 6 of the drawings includes the same sleeve support for the pole 12 and similar identifying numerals have been used. The blade 10 has also been indicated as 10. The connecting means is somewhat diiferent although operating in substantially the same manner. A fiat strip 66 bolted or welded to the blade 10 at 68 has upstanding end brackets 70 and 72 thereon. An angle iron cross piece 74 has pins 76 and 78 projecting therefrom into pivot apertures 80 and 81, respectively, in the brackets 70 and 72 respectively. The pole arms or rods 20 and 22 are Welded at 82 and 83 respectively, to the angle iron cross piece 74. The pole 12 is thus supported for pivotal movement on the blade 10. An arcuately shaped rack 84 has a base plate 86 securely bolted or welded at 88 to the blade 10 rearwardly of the strip 66. A metal rod 90 is embedded in or securely connected to the blade end of the pole 12. The rod 90 has a reduced blade end 92 that is received and shouldered in an aperture 94 in the cross piece 74. The rod 90 has an integral or welded hub 96 thereon upon which'is mounted a pinion gear 93. The teeth 100 on the gear or sprocket 93 mesh with coinciding apertures 102 in the arcuate rack 84.
The operation of the modification above described is substantially the same as in the preferred embodiment. The operator merely rotates the pole 12 from remote position and the pinion 98 moves in desired direction in the rack 84. Theengaging teeth and apertures hold the blade and pole in desired angular position ready for instant automatic change of position as desired.
While the embodiment of our invention shown herein is fully capable of performing the objects and advantages desired, it will be apparent to those skilled in the art that numerous modifications may be made without departing from the inventive concept disclosed herein. It is not intended that this invention be limited by the embodiments disclosed but only as necessary in accordance with the appended claims.
I claim:
1. A cement slab smoothing device, comprising: a blade; an operating pole having spaced arms pivotally connected to said blade; said arms having a sleeve attached thereto for receiving said pole in a rotational manner; an arcuately shaped member projecting from said blade; a rod projecting from said pole; and a releasable clamping connection between said member and said rod actuated by rotational movement of said pole.
2. A device as set forth in claim 1 in which said releasable clamping connecting includes an apertured cross plate on said spaced arms slideable on said member; a threaded nut on said cross piece having an eye portion slideable on said member; and a threaded end on said rod received in said bolt and movable into or out of clamped engagement with said member.
3. A device as set forth in claim 2 in which said pole arms have a sleeve attached thereto for receiving said pole in a rotational and longitudinal manner.
