spURFACING-TROWEL.
Specification of Letters Patent.
' Application led September `19, 1911. Serial No. 650,113.
To all wz-om t may concern:
Be it known that I, JOHN B. RUNNER, a
State of Indiana, have invented certain new and useful Improvements in Surfacing.
Trowels, of which the following is a specification.
This invention relates to surfacing trowels to be used in finishing the surfaces of cement work, such as walks, floors, etc.; and the object of the invention is to provide a trowelv of the above character in which the trowel blade may be tilted by manipulating the handle so as to impart the necessary inclination, such as is given the ordinary trowel blade by the operators hand, to impart the smooth finish to the cement surface.
A further object of the invention is to pro-- A further object of the invention is to provide a surface trowel for finishing cement surfaces in which the trowel blade pivotally engages the handle so that the position of the blade may be changed with respect to the handle when the latter is rotated about its longitudinal aXis, the trowel being further provided with certain means for temporarily securing the blade when -it is desired, to provide a rigid tool, often necessary in doing certain kinds of work.
I accomplish the objects of the invention by means of the trowel illustrated in the accompanying drawings, forming a part hereof, in whicl- Figure 1 is a top or plan View of the surfacing trowel. Fig. 2 is a side elevation, on an enlarged scale, of the trowel blade, sho-wing the mechanism for tilting the blade. Fig. 3 is a front elevation of the construction shown in Fig. 2, except that the mechanism for tilting the trowel blade and handle are elevated to assume a perpendicular position. Fig. 4 is a side elevation of the trowel, showing the blade occupying an inclined position when the trowel is moving in a direction toward the operator. Fig. 5 is a view in side elevation showing the trowel-handle standing onthe same parallel pla-ne as that shown 1n Fig. 4, except that the trowel-blade occupies an inclined position in which the plane of the inclination is in opposition to thatshown in Fig. 4, as when the trowel is rro'vmg in a direction away from the opera or.
Referring to the drawings, 10 represents the blade of the trowel which is preferably composed of a rectangular piece of thin sheet steel. The blade 10 is provided with a rib 11 which is mounted centrally and eX- tends longitudinally so as to stiften and keep the blade in proper alinement. The rib 11 is secured to the blade 10 by meansl of suitable rivets 12. Arranged midway of the ends of the blade 10 is a standard 13 which is provided with a base 14, the latter being providedwith a groove 15 to receive the rib 11 and thereby prevent the standard 13 from turning on the said blade 10. The standard 13 is secured to the rib 11 by means of the bolts 16. The standard 18 provides a bearing for the slotted-head 20, the latter forming a support for the handle. The slot-ted head 20 is retained in position on the standard 13 by means of a transverse bolt 21. The slotted-head 20 is provided with a spindle 23 which enters the end of the handle 24 to permit the latter to rotate in said spindle. The lower end of the handle 24 is provided with a pinion 26 and an annularly extending fiange 27. The pinion 26 engages the teeth on the curved arm 30, formed on the base 14, and the arm is recessed below the teeth, as at 31, and said recess is engaged by the annular flange 27 on the handle 24, the purpose of the recess and flange being to prevent accidental displacement or separation of the pinion 26 from the teeth on the curved arm '30 when the two are in engagement. By means of this construction, it will be noted that the inclination of the blade 10 Patented Mar. 26, 1912. y
may be changed with respect to the position occupied by the handle when the latter is rotated about its longitudinal axis in either direct-ion. This movement of rotation imparted t-o the handle forces the edge of the blade, in the direction in which the trowel isl being pushed across the surface of the cement upward, thereby allowing the heel, or opposite edge of the blade to draw over the cement and impart the desired smoothness to the cement surface. This tilting of the trowel blade is well known to those engaged in plastering or laying of cement, this necessary inclination of the blade being imparted to the ordinary hand trowel by the operators hand.
Tn the initial work of spreading the cement grout, to secure uniformity of thickness, portions of themass must be pushed or pulled around to the depressions, and it may be found desirable to have the blade rigidly fixed to the handle. To adapt the trowel for this part of the work, I provide means for temporarily securing the blade to the handle. This is accomplished by pro-A viding the slotted-head 2O with an integrally formed arm l10 which extends outward and upward alongside the outer face of the'curved toothed-arm 30. See Fig. 3. A clamp-screw 41 passes transversely through the upper end of the arm 40 and the said screw may be moved to firmly rest against the face of the arm 30. The clampscrew 4l enables sufficientpressure to be applied to rigidly hold the handle 24 and blade 10 together.
As heretofore stated, the slotted-head 20 is provided with a spindle 23 which projects into the end of the handle 24. This arrangement' allows the handle to be rotated independently of the slotted head 20 and also enables the handle to be removed from the slotted-head 20 so that the parts may be nested when moving from one place to another, it being noted that the separation between the pinion and the teeth on the arm 30 will take place when the handle is moved to assume a position indicated by means of the dotted line extending from A to A.
Having thus fully described my said invention, what I desire to secure by Letters Patent, is-
l. A surfacing trowel comprising a blade, a toothed-arm arranged on said blade, a han` dle supporting spindle pivotally mounted on said blade, a handle loosely engaging said spindle, and teeth carried by said handle to engage the toothed-arm and to change the position of the latter with respect to the handle when said handle is rotated about its longitudinal axis.
