@with tat-trs @anni @ffice GEORGE W. IVES, OE NORTH HAVEN, CONNECTICUT, ASSIGN OR TO HIM SELF AND ALFRED IVES, OF THE SAME` PLACE', Letters Patent No. 68,882, dated september 17,1867.

IMPROVBD BRICK MACHINE.

TO ALL WHOM IT MAY CONCERN: A

Be it known that I, GEORGE W. IVES, of North Haven, in the county of New Haven, andy State of Connecticut, have invented a new improvement in Brick Machines; and I do hereby declare the following, when taken in connection with the accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of-the same, and which said drawings constitute part of this specification, and represent, in

Figure l, a side view ofthe machine, with the mould inserted for the purpose of filling.

Figure 2, the same View, the mould moved out without obstruction; and in f Figure 3 the same to illustrate the operation of the machine when the movement of the mould is obstructed.

This invention relates to an improvement in what is known as the Vcrvalin Machine. In that machine, whenever any obstacle is offered to the free movement of the mould, as, for instance, when a stone is accidentally permitted to en ter in the clay, the movement of the machine must be arrested or some part of it is unavoidably broken--a serious objection to this otherwise perfect machine.

From this cause the machine is frequently broken, and to overcome this ditiiculty isthe object of my invention, which consists in combining with the mould-moving lever a second lever, upon which the power operates, and arrangedso that when toogreat obstruction is oiiered, the second lever will yield and permit the` power to go on, and thus notify the operator that the mould isA obstructed, and aii'orrl him an opportunity to remove such obstruction, with no danger of breaking any' part ofthe machine.

In order to the clear understanding of my invention, I will proceed to'describe the same as illustrated in the accompanying drawings.

A is the clay-box, B the driving-shaft, C the crank, which operates to move the mould-box D, as from the` position in fig. 1 to that in iig. 2, through the operation of the said crank upon' a. lever, E, as denoted in the several figures. i

Heretofore the crank has operated directly upon the lever E, so that as the movement of,the mould is obstructedthe crank must he' arrested, or the lever or similar. part of the machine must necessarily break. To prevent such breakage, I shorten the lever E, so that the crank C will revolve without reaching the said llever, and on to the lever E, and pivoted thereto, I hang a second lever, F, extending up so that the crank in its revolution will strike the said lever F. From the lever F an arm, G, extends, provided with aweight, H, for throwing hack the lever E after it has been moved by the crank from the position in iig. 3 back to that in iig. 1. If obstructions interfere with the free movement ofthe mould box l),` then the crank, striking the lever F, will press it down to the position denoted in Iig. 3, and so as to pass freely thereby, and when it has so passed, then the weight'H, assisted it may he hy a spring,f, returns the lever F to the position in fig. 1, and will so continue to act until the obstruction is removed. 'lhus all danger of breakage by obstruction is entirely avoided.

Having thus fully described my invention, what I claim as new and useful, and desire to secure by Letters Patent, is d The arrangement of the lever F, in combination with the lever E and crank or cam C, so as to operate substantially in the manner herein set forth.
