E. H. BUSCH GEMENT TROWEL Filed June 18. 1 25 Patented Dec. 1, 1925.
UNITED STATES 1,564,172 PATENT OFFICE.
EDWARD HARMAN BUSCH, OIE KENDALLVILLE, INDIANA.
CEMENT TROWEL.
Application filed June 18, 1925. Serial NO. 38,047.
To aZZ 207mm it may c0ncera:
Be it known that I, EDWABD HARMAN BUSCH, a citizen of the United,States, residing at Kendallville, in the county of Noble and State of Indiana, have invented certain new and useful Improvements in Cement Trowels; and I do declare the following to be a full, clear, and exact description of the invention, such as Will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to improvements in trowels used for finishing cement curbs and gutters, and it is the object of such invention to provide a novel device of this character, in which unique provision is made for changing the shape of the trowel, aecording to the shape to be imparted to the curb.
VVith the foregoing in view, the invention resides in the novel subject matter hereinafter described and claimed, the description being supplemented by the accompanying drawing.
Fig. 1 is a top plan view of a trowel constructed in accordance with my invention, showing the same in use.
Figs. 2 and 3 are vertical sectional views as indicated by lines 22 and 33 of Fig. 1.
Fig. 4 is a diagram illustrating difierent shapes which may be imparted to the trowel.
In the drawing above briefly described, the numeral 1 designates a thin sheet metal plate cf elongated form and having its end portions 2 and 3 relatively offset for simul taneously finishing a curb and a gutter. The
plate 1 is preferably reinforced to some extent along its longitudinal central portion by a strip 4 secured thereto by rivets or the like 5, both saicl plate and said strip being resilient so that by relatively extending or retracting the ends 2 and 3, difierent forma tions may be imparted to the plate, as indicated diagrammatically in Fig. 4. Novel provision is made for adjustably tying the ends of the plate in the relation to Which they may be adjusted, and in the preferred form of construction, the details described below, are followed.
An elongated handle 6 is shown, transverse to the length of the plate 1, oblique to such length, and suitably inclined, the front end of said handle being provided with lat eral arms 7 and 8 which project substantially in opposite directions and preferably diverge forwardly as shown. The arm 7 is pivotally connected by a bolt 9 with the end 2 of the trowel plate, said bolt preferably having a square head countersunk in an opening in the strip 4. The free end of the arm 8 is formed with a longitudinal slot 10 which is oblique to the length of the plate 1, and a clamping bolt 11 passes through this slot for connecting the arm 8 adjustably with the end 3 of the plate. The bolt 10 is preferably formed with a square head coun tersunk in an opening in the strip 4, as shown in Fig. 2. By loosening the bolt 11 the ends 2 and 3 of the plate 1 may be moved either toward or from each other by springing said plate at the bending points shown, and in eflecting this adjustment, turning of the handle 6 and the arms 7 and 8 about the bolt 9 as a pivot, causes the side walls of the slot 10 to act as cams which assist materially in drawing the end 3 inwardly or forcing it outwardly as occasion may demand. lVhen the bolt 11 is again tightened, the plate Will be held in the new position to which it has been sprung. Preferably, the
bolt 9 is loosened somewhat when adjusting the shape of the plate and is again tightened after uch adjustment. The intermediate position of the plate as illustrated in Fig. 4 is the one normally assumed and is the one in which the plate is originally stamped. Through the foregoing adjustment, the respective positions of the ends may be easily varied.
It Will be seen from the foregoing that a simple and inexpensive trowel has been provided, which may be used to accurately finish a curb and a gutter, the device being readily adjustable to produce curbs of diff'erent heights and shapes, as Will be clear from Fig. 4:.
As excellent results are obtainable from the details disclosed, they are preferably followed. However, within the scope of the invention as claimed, modifications may of course be made and it Will be obvious that the handle 6 and arms 7 and 8, may project beyond either edge of the plate 1, to be 0 erated either by a right-handed or a le thanded person.
I claim:
1. A cement working tool comprising a resilient plate whose ends are i*elatively oif set and adapted to be extended or re tracted by springing the plate into diferent shapes, a tie member connected to one end of the plate, and means adjustably connecting the other end of said plate with said tle member to hold the plate in any shnpe to whieh it is sprung.
2. A structure as specified in daim l; sad one end of the plate being pivotally connected to the tie member, said etljnstable conneeting means comprising a slot in the tie member oblique to the length of the plate, and a clamping bolt connected with the plate and received in sztid slot.
3. A eement working tool comprlsing :1 resilient plate whose onde me relatlvely olfset and adapted to be extended or retrztcted by springing the plate into diferent shepes,
an elongated handle having arms at its front encl projeeting laterlly in opposite directions and contacting with the ends of the plate, 21 pivotal connection between one of sztid ztrms and one endof the plate, the 0ther arm having a slot oblique to the length of the plate, and a clamping bolt passing through the slot of said other :trm and adjusteble conneeting the latter to adjacent plate end.
In testimony whereof I have hereunto affixed my signature.
EDWRD HARMAN BUSCH.
