Letters Patent N 104,870, dated June 28, 1870.

IMPROVEMENT IN MORTAR-MILLS.

lheSchedule referred to in these Letters Patent and-making part of the seine.

To all whom it may concern:

Be it known that I, JOHN ll/IGIJNTYRE, of Syracuse, in the county of Onondaga and State of New York, have-invented certain new and useful Improvements in Mortar-Mills; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use/the same, reference being had to the accompanying drawing forming part of this specification, in which- Figure 1 is a sectional side view of my invention Figure 2 is a plan view; and v Figure 3 is a detail view.

Similar letters of reference indicate like parts inthe several figures.

In ,the accompanying drawing- A is the mixing-mill; B is the vat for sinking the lime O is the tank for holding the paste or slakcd lime as the lime becomes slaked it flows under an adjust-able gate, 1), fig. 1, and through a coarse screen, 0, that prevents the largcpicces of lime from leaving the vat B, and as the lime leaves the vat it falls upon a revolving beating wheel, e, .that is suspended within a trough-sl1aped wire screen, G. The coarse part of the lime is worked and beaten up into a paste by the wheel 0, and falls into apaste-tank, O, that is situated below the screen G and, beater-whee].

Any lumps that are not pulverized by the wheel e, so as topass through the screen, work along to the open end of the screen and are discharged from the vmachine by a spout, g, fig. 2.

The screen G is suspended on the shaft H, so as to swing or rock thereon, and the rocking movement is obtained by a swinging lever, K, that is operated by a crank, 71, and suitable connecting-rods, I; It, fig. 1.

This rocking movement of the screen G prevents it from becoming clogged and works any unpulverized lumps along so that they are discharged from the screen and spout g.

From the tank 0 the paste s elevated and fed to the mill, as wanted, by the chain-pump 1), the flow of paste co-the mill A beingwegulated by a valve or cock'i.

The elevator E is" made with small buckets so that the pile of sand is fedto the conveyer gradually, and the screw conveyer f distributes the sand in the box F, so that it is fed evenly into the mill.

-When making hair-mortar, the hair is fed into the mill by hand.

The mixing device A is a rotating-wheel made up of arms 1 and 2, as shown by faceview, fig. 3, the central arms 1 having their faces beveled so as to throw the mortar outward on each side; and the outside arms 2 2, having their faces beveled in the opposite direction, to return the mortar to the central arms, and in this manner the mortar is beaten and finally delivered from the spout a. v

Fixedrods, m, are also arranged between the series of arms, to prevent the mortar from being carried around bodily with thearms.

The lower wheel of the chain-pump cam-be provided wit-h aseries of fingers 0r project-ions, to agitate or beat the lime-paste in the tank 0.

The mill is mounted on. a platform, N and wheels 11, so as to be taken to the various points where the mortar is required as the'looation of the building;

, work is changed.

Having thus described my invention,-

What I claim, and desire to secure byLottcrs Patent. is'

l. The combination of mill A, provided with stirrers or blades 1 2, and stationary rods m, with the conveyors f and E, and tanks B and 0, all constructed and arranged as and for the purposes set forth.

2. The rocking trough-screen G and pulverizcr c, in combination with the rods. It, It, and K, all con structcd and arranged as and for the purpose set forth.

8. The arrangement of the tanks B and 0, pump; D, screen G, conveyers E and 1 and mill A, with knives 1, 2, m, when all these parts are constructed and operated as and forthe purpose herein shown and described.

4. The arrangement of the cylinder A of the fixed bars at, and the single inclined arms 2 2, alternating with the double inclined arms 1, all constructed and operating as and for the purposes set forth.

The above specification of my invention signed by me this 31st day of May, 1870.
