SPECIFICATION forming part Of Letters Patent NO. 421,385, dated February 18, 1890.

' Application filed April 22, 1889. $eria1 No. 308,082. (No model.)

To all whom, it may concern:

Be it known that I, CYRUS CHAMBERS, .112, a citizen of the United States, residing; at Wynnewood, in the county of Montgomery and State of Pennsylvania, have invented certain new and useful Improvements in Brick- Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, of which Figure 1 is a plan view of the receiving end of a brick-machine off-bearing belt and adjuncts embodying my invention, the adjacent end of the cut-off frame and belt being shown. Fig. 2 is a side elevation thereof. Fig. 8 is a transverse section through the off-bearing belt, &c., taken at a point where the brick is nearly edged. Figs. 4t and 5 are like sections through the belt and its supporting-bar, showing the latter curved and plane, respectively.

This invention relates to an improvement in brick-machines, and more particularly in the off-bearing belts thereof, whereby the bricks when delivered upon said belts will be set on edge by the latter, and thus be in position to be removed by the off-bearers without liability of the side edges of the bricks being marred or defaced. Mechanism for effecting such edging of the bricks is illustrated in Letters Patent No. 301,4.71, granted July 8, 1884:, to George 11. Aregood, (and subsequently assigned to me,) to which patent reference may be had, said mechanism consisting of a supplementary inclined or twisted belt arranged with respect to the usual off-bearing belt, together with a guide for deflecting the advancing bricks upon said supplementary belt, whereby the latter takes up the bricks and redelivers the same edgewise upon the off-bearing belt.

My invention has for its object to accomplish this edging of the bricks in a more perfect, simple, and less violent manner; and to this end it consists, primarily, in a certain arrangement of the off-bearing belt whereby it shall directly perform such edging; also, in a certain guard-frame disposed with relation to the said belt; also, in a belts upporting bar of peculiar construction, all of which will be hereinafter fully described and definitely claimed.

Referring to the annexed drawings, A represents the receiving end of an oft-bearing usual manner.

belt of a brick-machine-such, for example, as the well-known Chambers machine shown and described in various Letters Patent of the United States. This belt passes around the tightener-pulleys B O and around the pulleyD on the end of the cut-off frame E in the It is then passed around a forward upright pulley F, whose shaft is journaled in a box f in the off-bearing frame G, said pulley being slightly elevated above the latter, as seen in Fig. 2. This pulleyF gives the belt a quarter-turn at ctt'. e., changing ;it from a horizontal to a vertical plane. The ;belt is then passed back and around a horizontal pulley H, mounted at the end of the frame E, which pulley returns the belt to a horizontal plane, as at In such position it proceeds under the quarter-turned portion Ct as appearing, and on out in the usual manner, to the end of the 0ff-bearing frame any desired distance. It will be observed that these pulleys stand so that their leading sides line with the approaching belt, as is common with quarter-turn belt-pulleys.

The operation is as follows: The bricks are delivered from the cut-off belt I at short intervals apart upon the off-bearing belt A, which is driven at a greater speed than the former belt in the usual and well-known way. The belt A carries the bricks forward, and as they approach the pulley F they are gradually inclined toward the lower horizontal portion a of thebelt till they reach a certain point,where they are carried along by both belt portions moving in unison, and the incline is sufficient to up-cdge the bricks, whereupon they are 'de livered wholly upon the horizontal portion a of the belt, as clearly shown.

It will sometimes happen when the machine is running at a high rate of speed, making, say, one hundred bricks per minute, that the bricks will be thrown with such force by and from the twisted portion of the belt as to fall over beyond a perpendicular, (indicated by dotted lines in Fig. 3,) and thus drop sidewise upon or even drop entirely off the belt. To

remedy this defect, I arrange above the outer edge of the belt-section a near the perpendicular of the twisted section, a guard-piece J, of wood or other suitable material, which is supported in brackets j, that are adjustably secured to the side of the off-bearing frame bymeans of bolts 7' passing through slots j in said brackets.

I sometimes secure to the frame E, adjacent to the upper twisted portion a of the belt, a correspondingly-twisted bar K, which is designed to support the latter. Although this bar may be flat in cross-section, as shown in Fig. 5, I prefer to curve or convex its bearingface, as the belt will conform to the curvature, and thus relieve the corners of the bricks from under pressure and prevent marring thereof.

Having thus described my invention, I claim as new and wish to secure by Letters Patent- 1. In a brick-machine, the off-bearing belt having the inclined or twisted first receivingsection upon which the bricks are wholly delivered and theadjacent horizontal section upon which the bricks are edgewise deposited by said first receiving-section, substantially as described.

2. In abrick-machine, the combination,with the cut-off and otf-bearin g frames, of the horizontal pulleys D and Hand the upright pulley F, arranged with reference to each other substantially as shown and described, and the single off-bearing belt with its inclined or twisted first receiving-section a and the adjacent horizontal section (1 substantially as set forth.

3. In abrick-machine, the combination,with the off-bearing frame and the off-bearing belt provided with the inclined or twisted section a and the adjacent horizontal section, of the guard-frame, arranged with relation to said sections substantially as described.

at. The combination, in a brick-machine, with the off-bearing frame and the off-bearing belt provided with the inclined or twisted section a, and the adjacent horizontal section (1 of the guard-frame arranged with relation to said sections and consisting of a longitudinal bar J, supported in slotted brackets j, adj ustably connected by means of bolts j with the side of the off-bearing frame, substantially as described.

5. In a brick-machine, the combination,with the off-bearin g frame and the twisted ofi-bearing belt mounted thereon, of a correspondingly-twisted supporting-bar secured to said frame with respect to the belt, substantially CYRUS CHAMBERS, JR. \Vitnesses:
