APPARATUS FOR SURFACING BRICKS AND TILES.

Application led June 11, 1915.

To all whom t may concern.'

Be it known that I, CHARLES C. VVOLPE., a citizen of the United States, residing at I-Iaydenville, I-Iocking county, Ohio, have invented a new and useful Improvement in Apparatus for Surfacing Bricks and Tiles, of which the following is 'a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a side elevation of apparatus embodying my invention;

Fig. 2 is a plan View of the same;

Fig. 3 is a view on a larger scale; and

Fig. 4L is a bottom plan view also on a larger scale of one of the rotary surfacing members.

My invention has relation to apparatus for imparting a roughened surface to tiles,

bricks and other structural shapes of terra cotta and clay, the surface imparted being what is commonly designated in the trade as a tex surface.

The Object of my invention is to provide apparatus which can be readily used in connection with the usual forming dies and which will impart the desired surface to the -clay bar or shape as it issues from the said die. A further objectof the invention is to provide means of this character which can be operated with very little, if any, additional power or expense.

Referring to the accompanying drawings, in which I have sh-own the preferred form of my invention andwhich will now be described, the numeral 2 designates the usual forming die of a brick or tile machine. 3 designates a suitable guideway which is placed in advance of the orifice of the die and in line therewith and is adapted to guide the bar 4L of clay (indicated in dotted lines) as it issues from the die. 5 designates rotary members which are provided at their lower sides with a plurality of pins or teeth 8. vided with spindles or shafts 6, which are free to rotate in bearings 7 on the guide 3. The spindles are movably mounted within the bearings, so that the rotary members 5 are free to move upwardly, s-o that the depth of the cuts in the clay bar made by the pins or teeth are determined by the weight of the rotary members. I preferably employ at Specification of Letters Patent.

These rotary members are prof Patented Mar. 2"?, 191?. seria1'No.3a,A7o. 4 I

least two of the members 5, one at each side of the guide 3, and partially overhanging the guideway, so that as the bar of clay7 travels to the guideway, the members 5 will be rotated by contact of the clay with the pins 8. The two members 5 being located at opposite sides of the guideway will be rotated iuthis manner in opposite directions, thereby scratching and re-scratching the upper surface of the clay bar and producing a complete roughing of such surface.

The numeral 9 designates a roller, preferably having a resilient or textile surface portion, and which is j ournaled transversely of the guideway beyond the scratching members 5. The purpose of this roller is to roll down the loose material left by the scratchers and to produce what is known as the tex surface.

It will be noted that no belts, pulleys or other means of transmitting power to the scratchers or rollers is required, the movement of these being effected by contact with the moving bar or column of clay. The device is extremely simple and effective in its 4operation and enables a tex surface to be produced with little, if any, additional labor or expense.

I do not desire to limit myself tothe particular embodiments of my invention which I have herein shown and described, since it is obvious that the guideway may be of any suitable construction, that more than two of the rotating scratchers may be employed, if desired, and various other changes may be made within the spirit of the appended claims.

I claim:

l. Apparatus Of the character described, co-mprising a rotary member having a plurality'of scratching points and located in advance of the expressing die of a clay working machine, said member being free to be rotated solely by the contact of its scratching points with the moving clay column, substantially as described.

2. Apparatus of the character described, comprising a guideway for the moving bar or column of clay, and rotary members overhanging the guideway from opposite sides and having each a plurality of depending scratching points or pins, said members being free to be rotated solely by the contact of said ,points or pins With the moving column of clay, and the two members having their centers of rotation at opposite sides of said guidevvay so as to be rotated in reverse directions, substantially as described.

3. Apparatus of the character described, comprising a guideway for the moving bar or column of clay, and rotary members overhanging the guideway from opposite sides and having each a plurality of depending scratching points or pins, said members 'being free to be rotated solely by the contact of said points or pins with the moving column of clay, and the two members having their centers of rotation at opposite sides of said guideway so as to be rotated in reverse directions, together with a surface roller journaled transversely of the guide- Way beyond said rotary members and having its surface adapted for contact with the surface of the clay column, substantially as described.

Ll. Apparatus of the character described, comprising a rotary member having a plurality of scratching points and located in advance of the expressing die of a clay Working machine, a bearing, a stem connected to said rotary member mounted Within the bearing and adapted to be freely moved therein, said member being free to be rotated solely by the contact of its scratching points with the moving clay column; substantially as described.

In testimony whereof, I have hereunto set, my hand.

CHARLES CURTUS WOLFE.
