MACHINE FOR MAKING BRICKS.

Specification of Letters Patent No. 601, dated February 15, 1838.

T0 all whom t may concer-n.'

Be it known that I, JESSE REEDER, of Cincinnati, in the county of Hamilton and State of Ohio, have invented a new and useful Improvement in Machines for Making Bricks, which is described as follows,v reference being had to the annexed drawings of the same, making part of this specification.

First. Construct a permanent circular stone or wooden foundation A, Figure 7 40 feet in diameter (more or less) rising to the surface of the ground to support a plat form B. Then a po-st C Figs. l and 3 of about 18 inches diameter is to be planted in the center of the circle rising 14 feet high. Then 8 pieces D Fig. l 8 inches square are framed into the center post radiating to the outer edge of the wall and resting upon the foundation. Then braces E Fig. l of the same size framed into each space 7 feet from the o-uter end to receive 7 joists F, in each space 6 by 8 inches. Then a iioor of oak or beech plank 2 feet wide 2 thicknesses of 4 inch stuff, broke joints, spiked down to the joists to support the molds in which the brick are made by a revolving wheel of about 8 tons weight.

2nd. The molds I are made of metal 4 (more or less) in a flight cast whole or in separate parts see Figs. l, 4, 5 and 6 so that they may be ground smo-oth ywith a tenent on the dividing pieces to go through the side pieces and fastened by a draw pin-a groove the of an inch deep extending from the mortise each way to the edge of the side pieces to receive the shoulders of the tenented bar of .l inch thick and 2% inches deep: the dividing bars would be more durable if made of wrought iron. The side pieces cast same depth inch thick at the top edge and l inch at the bottom with mortises to receive the tenents of cross bars and flanges on each side with a. holein each to receive a spike to fasten it down. Although I have here described a mold constructed in separate parts yet I prefer the one cast whole. The followers K Fig. 7 are cast of an inch thick fitting the inside of the molds with an inch and a i socket and 15; inch deep to receive a pin L 'pressing through the floor -to a treadle M which, by stepping upon it, will raise the brick. The molds are to be set to a circle drawn on the platform 4 inches from the periphery leav- Ing a suitable space between each flight.

3rd. The wheel N Fig. l before mentioned, isv to be made of timber or other material from 8 to l0` feet diameter with a shaft O through the center fastened to the center post by 2 semicircular bands P and a swivel bolt Q, passing through it into the end of the shaft. The wheel to be of about 3 tons weight propelled by a horse or lby oxen hitched to the shaft inside the wheel and molds. The molds are lilled with clay as dug from the bank and 3 or 4 revolutions of the wheel passing over them willV form the brick.

4th. As a substitute for the wheel a wooden or metal hammer a Fig. 11 maybe used weighing about 600 pounds with a shaft b extending to the center post and fastened by a khinged band around it and bolted l to the sides of the shaft, having a cast roller o Figs. l and 2 near the hammer on the under edge of the shaft to slide up an inclined scantling rising about one' foot from the center of one mold to the center of another and then suddenly falling olf the end upon the clay on the molds and thus pounding it into a solid mass.

The invention claimed by me the said JEssE REEDER and which I desire to secure by Letters Patent consists in- The combination of the circle of molds and their appendages with the wheel N for Y Y WM. l?. ELLIOT,
