M MAURER DEVICE FOR ORNAMBNTING PAVEMENTS.

DEVICE FOR ORNAMENTING PAVEMENTS.

SPECIFICATION forming part of Letters Patent No. 519,919, dated May 15, 1894.

Application filed May 8,1893. Serial No. 473,373. (No model.)

To all whom it may concern:

Be it known that I, MARTIN MAURER, of the city of St. Louis and State of Missouri, have invented certain new and useful Improvements inDevices for OrnamentingPavements. of which the following is a full, clear, and exact description, reference being bad to the accompanying drawings, forming a part hereof.

Myinvention relates to an improved i tool for ornamenting artificial stone and other forms of pavements dnrin g the process of laying the same, and consists in the novel construction, combination and arrangement of parts hereinafter specified and designated in the claims.

In the drawings: Figure 1 is a plan View of my improved tool and a portion of a pavement, illustrating the mode of application in ornamenting a pavement. Fig. 2 is a sectional side elevation of same taken on the line A-A of Fig. 1. Fig. 3 is a sectional side elevation of the improved tool, with the terminal flanges of the cylinder removed but shown in dotted lines, and with parts broken away. Fig. iisa detailed section illustrating the manner of mounting the cylinder, with said cylinder indicated in dotted lines.

The object of my invention is to provide an improved hand-tool for ornamenting or laying off artificial stone or other pavements while in a plastic state during the laying thereof, and which tool shall be efficient in operation for such purpose, simple in construction and reasonable in cost. v

By the use of my improved tool I produce simultaneously a large number of distinct indentations in the plastic material by a single movement of one of the operators hands in which the tool is held.

Referring again to the drawings, 1 indi cates the main body of the tool, which is preferably in the form of a plain cylinder having squared ends, a smooth outer peripheryand a longitudinal bore 2.

3 indicates a series of separate sections curved transversely to conform to the outer peripheryof the body 1, and having radial meeting edges in contact, so that when all the sections are united and placed in position upon said body they form a cylindrical shell thereon havingthe definite construction here inafter mentioned. Each of the sections 8 has a connecting series of projections 4 upon its outer surface, forming a determinate portion of a definite design, in relief, upon said outer surface, arranged to connect with other definite portions of adjacent sections, and form a complete cylinder with a definite and complete design upon its outer surface, adapted to indent in a plastic surface when said cylinder is rolled upon the same. Each of the sections 3 has also an integral terminal flange 5 in the form of a segment at each terminal thereof, the same projecting above the outer surface of each and uniting with the flange of adjacent sections to form complete annular terminal flanges upon the cylinder projecting beyond the outer surface thereof.

6 indicates a spindle which loosely engages in the bore 2 of the body 1 and has its opposite ends squared and provided with a threaded bore 7 in which islocated a screw 8 having a thread upon its inner portion and a plain outer surface 9.

10 indicates a U-shaped yoke, the arms of which are provided with perforations or bearings 11 which are loosely engaged by the smooth surface 9 of the screws or bolts 8. Said yoke 10 is thus loosely mounted upon the spindle 6. Loosely mounted upon said spindle between each of the arms andthe adjacent end of the body 1 is a washer 12. The complete cylinder constructed as above described, is thus loosely mounted to revolve within the yoke 10. A handle 13 has one of its ends secured to the yoke 10 centrally of the length thereof, by means of a suitale bolt 14 and a nut 15, so that said handle projects from the outer surface of said yoke at aright angle thereto.

, The series of sections 3 may be secured in the above described position upon the cylindrical body 1 in any known manner, such for instance as by means of screws or bolts 16 having a threaded inner portion and passed through countersunk openings 17 formed in each of said sections and engaging threaded openings 18 in said body 1, so that the heads of said bolts or screws will be flush or below the outer surface of each section.

improved tool, is made of metal and solid, so as to embody as much Weight as possible, as the Weight of the tool should be such as to I The body 1, as well as all the parts of my sink the projections 4 their full depth into the plastic compound and bring the smooth intervening spaces upon the outer surface of the sections into contact with the surface of the plastic compound.

The operation is as follows: 19 indicates a body of plastic compound, such as plastic pav-.

ing compound, laid upon a suitable foundation 20 of cinders or other material. This material is first providedwith a smooth unbroken upper surface, and then the improved tool is rolled over this surface while. same is in a plastic condition, by means of the handle, 14 and the projections 4 will engage" said plastic material and produce upon its surface. correspondingindentations, and as the forward. movement of the tool continues, a complete and definite designwill thereby be produced upon the plastic compound, the sectional cylinder rolling over and over continuously. tion of indenting the design in the plastic compound, the terminahflanges 5' will. produce a straight border line or indentation 2lat each margin-a1 edgeof the design thus produced. Likewise, additional designs may be formed in the plastic bodyalongside of and parallel with the previously form-ed design, by placing the annular flange 5 of. one end of the sectional cylinder in engagement with theseparate border line 21 previously formed. By'proper attention upon the part of the operator'he may make the succeeding designs merge intoand correspond with the configurations of the preceding design; so as to form a com-pleteornamental surface upon the plastic body having a width many times in excess of the length. of the cylindrical.

body 1.

I have found in practice that my improved tool is very efficient in the operation above described, making with one movement or stroke of the hand a large number of marks or indentations in the plastic material.

I prefer to make the sectional cylinder about one foot in length, so as to retain its size and weight within such bounds that thetool may be readily handled by a single operator.

It will be seen that this. tool is entirely independent of exterior devices.

Simultaneously with. the opera- I am aware that prior to my invention a roller formarking designs in artificial stone had been constructed with a marking surface in detachable sections, held in place by rings threaded upon the ends of the roller, and I therefore, do not claim such as my invention.

What I claim is- 1. The improved tool for ornamenting artificial stone,-comprising a main body 1 in the form of a plain cylinder'having squared ends,

a smooth outer periphery and a longitudinal bore 2, a series of separate sections 3 curved transversely to conform to the outer periphery of said body, and having radial meeting edges in contact, each of said sections having a connecting series of projections 4 upon its outer surface forming a determinate portion of a. definite design in relief, and each section having .anintegral flange 5 in the formof a segment at each terminal. thereof, the same projecting beyond theouter surface of the section. which carriesit and unitingw-ith the flange of adjacent sections toform complete annular terminal flanges, a spindle engaging the bore of said body, and a suitable handle applied to said spindle, substantially as here- .in specified.

2. The combination, ina tool for marking artificial stone, of a main body or roller .carrying designs in relief upon its outer periphery, and having a longitudinal-bore 2, a spin-- vdle 6 mountedin said bore and having its ends squared and provided with a threaded bore 7, screws 8 having threads upon their inner portions and the plain outersurface,and engaging said bores 7 of said spindle, a U-shaped yoke
