To all whom it may concern:

Be it known that I, THOMAS S. Rouse, a citizen of the'United States, residing at Brazil, in the county of Clay and State of Indiana, have invented certain, new and useful Improvements in Brickmaking-Ma chines, of which the following is a specification.

This invention relates to brick making machines and more particularly to a machine or mechanism adapted to ornament or mark in a peculiar manner'one or more of the exterior surfaces of a brick, whereby when the brick is assembled with others in a building the entire mass will produce a certain desired effect.

One of the objects of the present invention is to provide a simple 'and'practical mechanism of the above general character which will be inexpensive to'manufacture, install and operate. A further object is to provide a mechanism of the above character which will be reliable and efiicient in use and operation. A further object is to provide a mecha-' nismof the above-mentioned character adapted to treat or operate upon one of the surfaces of a clay stream during the manufacture of ornamental brick.

Other objects will be in part obvious from the annexed drawings and in part indicated in connection therewith by the following analysis of this invention. This invention accordingly consists in th features of construction, combination of parts and in the unique relations of the members and in the relative proportioning and disposition thereof, all asmore completely outlined herein.

To enable others skilled in the art so fully to comprehend the underlying features thereof that they may embody the same by the numerous modifications in structure and relation contemplated by, this invention, drawings depicting a preferred form have been annexed as a part of this disclosure, and in such drawings, like characters of reference denotecorresponding parts throughout all the views, in which- I Figure 1 is an end elevational view of the complete device in operative'position showing the manner in which it is adapted to operate upon the clay stream passing therethrough; Fig. 2 is a plan view of the same which the claystream is adapted to pass.

he upper .ends of these bolts 3 are furnished with lock nuts 5 engaging the upper and lower surfacesof the table, thus forming an adjusting mechanism for changing the relative height of the table with respect to the cross bars'and the top or upper surface of the clay stream passing therethrough. Upon the table 1 and immediately above the clay stream, as indicated in Fig. 1 of the drawings, there is mounted two upwardly projecting bosses 6, preferably formed integrally with the table and located vertically above the clay stream and in tandem with respect to its direction of motion. These bosses are bored out centrally and are adapted to act as guides for reciprocating plungers 7 provided at their lower ends with plates 8, lying in the same plane as the table 1 and above the top of the clay stream. Guide 'pins 9 project upwardly from the plate 8 through suitable openings in the table 1, and move vertically as the plunger is reciprocated, thus preventing relative rotary movement of the plate 8 and associated parts. Immediately below this plate 8 and in contact therewith is a substantial wooden platen 10 of sufiicient size to completely cover the width of the clay stream and have its sides and lower surfaces covered with fleece or the like, as indicated, adapted to contact with the upper surface of the clay stream on depression of the plunger. Into the upper end of the push rod or plunger 7 is secured, as by means of a threaded connection, a push rod 11, having suitable adjustable lock nuts 12 at its upper end and a spring 13 adapted to be compressed between washers l4: and 15 engaging the lock nuts 12 and boss 6 respectively. These look nuts 12 serve as a means for compressing the spring 13 aboutthe push red 11, and thereby determine the force with which the plunger 7 and associated. parts return when depressed. These reciprocating plungers may be operatedin any desired manner, but the mecha-. nism hereinafter described is believed topossess certain" desirable advantages. A

' cam shaft 16 is. supported in bearings 17 near its-ends, which in turn are supported by the camshaft brackets 18 securely bolted or otherwise secured to the top of the table 1, and preferably occupies a position parallel and above the clay stream. Upon this cam shaft'l6 and spaced apart a distance substantially equal to that between the centers of thebosses 6 on plate 1 are securely mounted twocams 19 of similar design, having their throws diametrically opposite one another. Cam shaft 16 is held in position longitudinally by two collars 20 attached thereon and immediately outside of the cam shaft bearings17'. A pulley 21 is secured to one end of the shaft, beyond one of the set collars 20, adapted to receive power from any convenient sourceand transmit the same in a manner to'rotate the shaft 16 and cam 17 associated therewith.

Parallel to the cam shaft--17 is a tappet shaft 22 supported in the middle in a suitable bearing 23 firmly bolted or otherwise secured to the top of the tablel between the cam shaft brackets 18 and bosses 6. This- V collars at, each end.- As the tappet arms 24 oscillate on the shaft 22 and being similarly disposed thereon, as are the cams 19 'on' shaft 16, extend backward and directly over these cams 19 whereby they are oscillated at each rotation of the. cam shaft. The tappet arms 24 also extend upwardly and directly over .the push rods 11. At their ends are preferably provided adjustable set screws having lcck nuts 26 which depress rods 11 in their downward movement, the set screws 26 serving as a means of relative adjustment between the rod 11, tappet arms 24 and cam 19.

- Having described the construction the operation thereof may be stated as follows: The shaft 16 being driven from the pulley 21 rotates at a desired rate of speed and causes one of the cams 19 to raise under one end of its tappet arms 24, thus depressing the set screw 26' at the other end and causing the push rod 11 and coveredplatens 10 all to be similarly depressed. Asthe'fabric comes in contact with the top of the clay column it presses back onto the column in a heterogeneous mass the small cuttings and particles which have previously been made and distributed over the ban The throw of the cams 19 and the relative location of the-tappet shaft 22 with respect to the push rod 11 and cam shaft 16 are so proportioned as to give the plunger 7 the necessary vertical thrust. The throw of the two cams 19 being opposite the two plungers 7 are alternately depressed-and raised by the turn spring, and at such a rapid speed relative to the slow moving clay stream that the cuttings are evenly pressed onto the clay bar without impeding its movement over the associated measuring table.

It is thus seen that the present invention rovides a simple and practical mechanism or ornamenting and finishing clay streams in the manufacture of brick and one particularly adapted to accomplish among others 211 (if the objects and advantages above set ort Without further analysis, the foregoing will so fully reveal the gist of this lnvention that others can by applying current knowledge readily-adapt it for various applications without omitting certain features that, from the standpoint of the prior art, fairly constitute essential characteristics of the generic or specific aspects of this invention, and therefore such adaptations should andare intended tobe comprehended within the meaning and range of equivalency of the following claims:

Having thus described my invention what I claim as new and desire to secure'by Letters Patent is:
