No. 767,103 Int. Cl. E01c 19/30 US. Cl. 94--48 Claims ABSTRACT OF THE DISCLOSURE A lightweight portable machine for concurrently compacting freshly poured concrete and smoothing the surface thereof, which machine includes a vibrating plate pivotally supported between two elongate rollers in which openings are formed, and a handle extending rear-wardly from the plate for not only moving and guiding the device, but which permits the plate to be placed in a first concrete smoothing and compacting position when the machine is moved forwardly, and in a second position where the plate serves the same function when it is moved rearwardly.
BACKGROUND OF THE INVENTION Field of the invention A machine for concurrently vibrating a body of fresh- Iy poured concrete and smoothing the surface thereof as it is moved forwardly and rearwardly thereover.
Description of the prior art Although numerous machines and like devices have been devised and used in the past to smooth or finish the surface of freshly poured concrete, as well as compact the concrete. Such equipment have been heavy and cumbersome, and not adapted for use on small areas of of concrete such as sidewalks, or the like. The present invention overcomes the disadvantages of such prior equipment by providing a portable, lightweight, manually operable machine that may be used to concurrently vibrate and compact freshly poured concrete, as well as smooth and finish the surface thereof.
SUMMARY OF THE INVENTION A machine for concurrently vibrating and finishing the surface of freshly poured concrete, which device includes side pieces that serve to hold two hollow, perforated rollers in fixed longitudinally spaced relationship. A plate is pivotally supported from the side pieces between said rollers, from which plate a handle extends upwardly and rearwardly to aid in moving and guiding the device. The handle is also used to selectively move the plate into either first or second positions as the machine is moved forwardly and rearwardly over a body of concrete. Power means are operatively associated with the plate to vibrate the plate and the rollers.
The vibrating rollers serve to force aggregate downwardly into the concrete, as well as cause air contained in the concrete, together with any excess water, to rise to the surface. Excess water rising to the concrete surface serves as a lubricant to impart a smooth surface to the concrete as a portion of the plate when in the first position slidably engages said surface.
A major object of the present invention is to provide a portable, lightweight, inexpensive machine for concurrently compacting freshly poured concrete by dispelling entrained air and excess water therefrom, and smoothing the surface of the compacted concrete.

FIG. 9 is a side elevational view of a side elevational view of a prime mover that drives a second form of eccentrically loaded member to impart vibrations to the concrete.
DESCRIPTION OF PREFERRED EMBODIMENTS The concrete vibrating and finishing machine I is shown in a first form in FIG. 1, and in a second or modified form I in FIG. 9. The form I of the invention includes first and second hollow rollers A and A in which spaced perforations or openings 10 are formed, for reasons that will be explained hereinafter. Rollers A and A are rotatably supported in transverse longitudinally spaced relationship by two parallel side pieces B.
A plate C is pivotally supported from the side pieces B, and is situated between rollers A and A. An engine D is rigidly supported in a fixed position relative to plate C, with the engine D in the first form I of the machine driving an eccentrically loaded pulley E, and in the second form of the invention, rotating an eccentrically loaded body E, as shown in FIG. 9.
An elongate handle F is rigidly secured to plate C, projecting upwardly and rearwardly therefrom. Handle F is not only used in moving aird guiding the machine, but permits plate C to be selectively disposed in a first position shown in FIG. 5 or a second position illustrated in FIG. 6. Stops G shown in FIG. 3 prevent movement of the plate C beyond the first and second positions.
When the machine is being moved forwardly, the plate C occupies the first position shown in FIG. 5. However, when the device is being moved rearwardly, the plate C occupies the position shown in FIG. 6.
In operation, when the machine is moved across the upper surface of freshly poured concrete I (FIGS. 5 and 6), the plate C is vibrated, as are the rollers A and A. The vibrating rollers A and A force aggregate downwardly into the concrete and cause entrained air bubbles and excess water to rise to the surface of the concrete. Obviously, the escape of such air and excess water tends to compact the concrete. The water which rises to the surface tends to provide a lubricant on the upper surface of the concrete J as the plate C slides thereover to impart a smooth finish to the concrete.
The rollers A and A are structurally identical, and accordingly, only one roller need be described herein as to structure. Roller A includes two circular rigid end pieces 12, in each of which a central opening 14 is formed. A cylinder 16 of a perforated sheet material such as expanded metal, or the like, is provided, that slips over the end pieces 12 and is secured thereto by conventional means.
Pairs of transversely aligned openings 18 are formed in the ends of side pieces D through which transverse shafts 20 extend. Each shaft 20 extends through aligned pairs of the openings 14 and '18 and rotatably supports one of the rollers A or A thereon. The ends of shafts are threaded (not shown) which extend outwardly from the side pieces B to be engaged by nuts 22.
Plate C, as may best be seen in FIG. 3, includes forwardly and rearwardly disposed, upwardly curved end portions 24 and 26, as well as side walls 27. The end portions 24 and 26 develop into arcuate guards 24a and 26a that are disposed above rollers A and A, and extend at least partially thereover.
A platform 28 extends between end portions 24 and 26, which platform is secured to said end portions by bolts 30, or other conventional means. Transversely aligned, upwardly extending portions 32 are provided on the sides of platform 28, and bores are formed therein through which bolts 34 extend. Bolts 34 also extend through transversely aligned bores (not shown) formed in side pieces B. The bolts 34 serve to pivotally support the platform 28 and plate C from the side pieces B.
Engine D is rigidly secured to a longitudinally extending bracket 35 that is afiixed by conventional means to the center upper surface of platform 28, as shown in FIG. 1. Two transversely aligned, upwardly extending arms 36 project from side pieces B that support a cross bar 38 therebetween. The cross bar 38 has two upwardly extending, transversely spaced brackets 40 mounted thereon, which also support a shaft 42 therebetween. Shaft 42 rotatably supports the eccentrically loaded member E in the manner illustrated in FIG. 1.
Member E comprises a pulley 44, and a Weight 46 is affixed thereon in an off-centered position. A driving pulley 49 on engine D, as may be seen in FIG. 2, is connected by an endless belt with pulley 44. Handle F (FIG. 1) extends upwardly and rearwardly from the first form of the machine I, and when pivoted, permits the plate C to be disposed either to the first position shown in FIG. 5 or the second position illustrated in FIG. 6. Handle F permits the first form I of the invention to be guided and moved forwardly and rearwardly over the surface of the body of cement I.
When the engine D is actuated, the eccentrically loaded member E is rotated and imparts vibration to the platform 28, which is transmitted from the platform to the side pieces B, the rollers A and A, and the plate C. Vibration of the rollers A and A results in forcing the aggregate contained in the concrete body I downwardly therein, and at the same time causes entrained air in the concrete to rise upwardly to escape therefrom. Also, due to vibration of the body of concrete J, any excess water contained therein is caused to pass upwardly to the upper surface thereof.
When the first form of the invention I is moved forwardly over a body of concrete J, the handle F is used to pivot plate C into the first position shown in FIG. 5 where the rear portion of the plate is in sliding contact with the upper surface of the body of concrete. Excess water that rises to the surface of the concrete body I serves as a lubricant to impart a smooth finish thereto as the concrete is slidably engaged by the plate C.
When the first form of the machine I is moved rearwardly, the handle F is used to pivot the plate C into the second position shown in FIG. 6 when the forward part of the plate is in sliding contact with the upper surface of the body of concrete I. The action of the first form of the invention I when moved rearwardly is the same as when moved forwardly.
Stop G shown in FIG. 3, includes a vertical, upwardly extending pin 50 afiixed to plat form 28. One of the side pieces B is provided with a horizontal, inwardly extending lug 52 in which a vertical bore 54 is formed. Pin 50 is vertically movable in bore 54. First and second longitudinally spaced washers 56 and 58 are secured to pin 50 and disposed on opposite sides of lug 52. When first washer 56 is in contact with lug 52, as shown in FIG. 3, the plate C is disposed in a first position. Likewise, when the second washer 58 contacts the lug 52, the plate C is disposed in a second position as illustrated in FIG. 7.
The second form I of the invention is the same as the first form I, except that the arms 36, cross bar 38, and the pulley assembly shown in FIG. 8 is eliminated therefrom. Also, in the second form I, the engine D is mounted directly on the platform 28 by conventional means, with the pulley being replaced by an off-centered, relatively heavy rotatable body 60, as shown in FIG. 9. R0- tation of body 60 results in vibration being imparted to plate C, and rollers A and A in the same manner as in the first form of the device.
Both the first and second forms I and I operate in the same manner and produce the same results. Guards 24a and 26a prevent particles of concrete from being thrown onto platform 28 and engine D during operation of the machine.
As this invention may be embodied in several forms without departing from the spirit or essential characteristics thereof, the present embodiment is simply illustrative. Also, since the scope of the invention is defined by the appended claims, all changes falling within the metes and bounds of the claims, or that provide their functional as well as conjointly cooperative equivalents are therefore intended to be embraced by these claims.
