JOI'IN PARKI-IILL, OF ROCHESTER, MINNESOTA.

TROWEL.

To all whom it may concern.

Be it known that I, JOHN PARKI-IILL, a citizen of the United States, residing at Rochester, in the county of Olmsted and State of Minnesota, have invented certain new and useful Improvements in 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.

This invention relates to tro-wels for plasterers use and particularly to trowels for the performance of the work known to plasterers as splatter-dashing.

The object of the invention is to provide a trowel of the character referred to, by means of which a plurality of separate quantities of mortar or plaster may be taken up by one operation of the tool and all thrown upon the wall, separated regularly from each other, by the continuation of the same operation, the mortar being deposited on the well in separate parcels, whereby the mortar is more uniformly distributed than is possible from a single blade.

With this object in view, the invention consists in the improved construction of trowel for the purpose named which will be first fully described hereinafter and after ward specifically claimed.

In the drawings forming part of this specification; Figure 1 is a side view of my improved trowel; Fig. 2 is an end view thereof; Fig. 3 is a plan view of a modified form of the trowel; Fig. 1 is an end view thereof; Fig. 5 is a plan view of another modified forn of the invention; Fig. 6 is a side view thereof; Fig. 7 is a vertical cross-section of the same.

Referring more particularly to Figs. 1 and 2 of the drawing, 1 denotes the main blade of the trowel which is here shown as being of rectangular oblong form. To one side of the blade are secured handle shanks 2 carrying a handle 3 which extends parallel with the blade, as shown. In the blade is formed a series of longitudinally-disposed rectangular holes 4; which are spaced at suitable distances apart, and in the outer edge of the blade between adjacent holes 4: are formed rectangular notches 5 forming the holes 4 the blade is cut around three sides of the hole and the portion of the material thus cut is bent outwardly at right angles to the blade and forms plates or tables 6. In the Specification of Letters Patent.

same manner the material between the cuts forming the notches in the blade is bent out wardly at right angles to the blade and forms plates or tables 7. On the outer edge of the blade, between each of the notches 5 and in line with the holes 4:, are formed right-angularly projecting tongues or tables 8. The plates or tables 6, 7 and 8 when thus formed serve as independent blades which when the trowel is inserted into the mortar will each take up a separate quantity of the mortar, which,by a proper manipulation of the tool, is uniformly thrown upon the plastered surface to be finished.

In Figs. 3 and 4 of the drawing is shown a modified form of the trowel which in this instance consists of a blade of substantially oblong form, having on one end a shank to which is secured a handle 10. In the blade are formed longitudinal rows of openings 11 between each of which the material left forms a plate or table 12. The material may be cut from the blade to form the tables 12 of any desired shape, the latter being here shown as of octagonal form. The material between the longitudinal rows of openings 11 and tables 12 and along the side edges of the blade is bent down or folded upon itself, thus strengthening-the connections between the tables. In forming the tables, those of one row are disposed opposite to the openings of the adjoining rows, as shown.

In the last three figures of the drawings the trowel is shown as comprising a blade 18 having on one end a right angularl formed shank 14 to which the handle 15 is attached. In this form of the trowel the blade is constructed wit-h a plurality of openings 16 arranged to form plates or tables 17 which, when the blade is engaged with the mortar, will lift separate loads or quantities of the same in the same manner as described in connection with the first forms of the invention. The material thus taken up is thrown by the trowel upon the plastered surface to be rough coated in the manner described. The openings 16 and plates or tables 17 formed in the blades 13 may be of any suitable size or shape, the same being here shown as hexagonal. The metal forming connections between plates or tables is of suflicient width to firmly support the latter but is not wide enough to take up mortar. By forming my improved trowel as herein shown and described it will be seen that the one motion of lifting the trowel through the mortar Will load the tables with separate loads of mortar which will automatically equalize in size. This is one of the desirable features of the tool as by this means the mortar may be uniformly applied to the wall. In thus applying the rough finishing coat, the loads of material carried by the separate blades or tables will not be thrown on top of each other as is frequently done in the usual method of applying the rough finishing coat on work of this character.

From the foregoing description taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood with out requiring a moreeXtended explanation.

Various changes in the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention, as defined in the appended claims.

What I claim is:

l. A trowel comprising a blade having a plurality of openings and by the sides of said openings a plurality of tables sutficiently separated from each other to prevent the taking up of mortar between them.

2. A trowel comprising a blade having a plurality of separate flat tables of less area than the spaces by which they are separated, whereby mortar may be taken up by the tables only.

A trowel comprising a blade having a plurality of separate tables at substantially right angles to the blade, the tables being sufficiently separated from each other to prevent the taking up of mortar between them.

t. A trowel comprising a main blade having a row of openings, the material displaced from each of said openings being bent at one side thereofsubstantially at right angles to the blade forming a row of tables, and tongues bent at the edge of the blade opposite each table forming an additional parallel row of tables.

5. A trowel comprising a main blade hav ing a row of openings, the material displaced from each of said openings being bent at one side thereof substantially at a right angle to the main blade, and a row of notches cut in the edge of the main blade alternating with the tables, the material displaced to form said notches being likewise bent at substantially right angles to the main blade to form a second parallel row of tables.

6. A trowel comprising a main blade having a row of openings, the material displaced from each of said openings being bent at one side thereof substantially at a right angle to the main blade forming a row of tables, a row of notches cut in the edge of the main blade alternating with the tables, the material displaced to form said notches being likewise bent at substantially right angles to the main blade to form a second row of tables, and substantially right angle tongues at the edge of the main blade forming a third row of tables.

7 A trowel comprising a main blade having a row of openings, the material displaced from each of said openings being bent at one side thereof substantially at a right angle to the main blade forming a row of tables, a row of notches cut in the edge of the main blade alternating with the tables, the material displaced to form said notches being likewise bent at substantially right angles to the main blade to form a second row of tables, and substantially right angle flanges at the edge of the main blade forming a third row of tables, the individual tables of each row alternating with those of the adjacent row.

8. A trowel comprising a main blade cut to form a series of plates or tables connected together by integral connecting strips, said connecting strips being bent or folded upon themselves at substantially right angles to the main blade, the longitudinal edges of the blade being also bent at substantially right angles to the main body thereof.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
