To all wlmi/ aY it may concern:

B'it known that I, CLAUS C. BnANnnLL, a. citizen of the United States, and a resident of Chicago, in the county ot' Cook and State of Illinois, have invented certain new and useful Improvements in TampinU-Machines for Concrete and other Like l\ aterial, of which the following, when taken in connection with the drawings accompanying and forming a part hereof, is a full and complete description, suliicient to enable those skilled :in the art to which it pertainsto understand, make, and use the same.

This invention relates to devices used principally' in tanipiug the concrete in a box or mold, while such concrete is in a plastic condition, in the making oi' concreti: blocks for building4 purposes. And the object of the inventionv is to obtain a device by means of which 'the tamping of the concrete mixture from which a hollow concrete building block is being molded, during the entire time the mold is being filled maybe done and, at the same time, no tamping will be done upon or to the part or portion of the mold by means of which a hollow block is made.

A. further object is to obtain a device of the character described by means of which any desired variation in the force of the tamping blows delivered by the device is easily secured.

A ,tuitherzobjcct ot the invention is to ob- Atain a device ot' the character described Fig. i?, is a side elevation of the device. Fig.

I 3, is a vertical section on lines3-3 of Fig. l,

viewed in the direction indicated by the arrows. Fig, 4, is a. horizontal.section on line 4-4 ot Fig'. l, viewed iu the direction indicated by the arrows. Fig. 5, is a front clevation or" the lower ends ot the hammers of the device and of a mold suitable to .form therein a hollow concrete block. Fig. (3, is a side elevation, on an enlarged scale, of a latch forming an element of 'the device. Fig. 7, is a front elevation of the latch illustrated in, Fig. t3.

A reference letter applied to indicate a given part is used to designate such partbearings D, D', respectively. Bearings D,

D', are rigidly secured to the side bars a, as by lag screws d, al.

E, 1s a driving pulley, and E.' is a loose pulle on shaft lC.

F, F', F2, F8, F4, respectively, are sprocket Wheels rigidly secured on shalt C, and f, f', f2, f3, f, are sprocket wheels loosely mounted on shaft C. 1

Gr, G', G2, G3, Gr, are sprocket chains respectively' extending over the sprocket Wheels t of the F', f, series. The sprocket chains are actuated by the rotation of shaft And when the device is in operation the Shafts C, C', with the sprocket wheels thereon and the chains of the G series, extending over such wheels, are continually moving.

H, H', H2, H3, Ht, are elevating abutments on the lcorresponding sprocket chains of the G series.

i I, I', z", I2, I3 I", 4, are hammers which are 4respectively provided with the vertical Shanks J, J', j', J2, J3 J, jt.

y', jg, and ja are verticalshanks to additional hammers which are located in the same row as are hammers i', i* and are duplieates of hammers I, l2 and I8. i.

The cross bars a', of the frame A, are

respectively provided with apertures through which the Shanks ot' the J, j, series extend, such Shanks itting loosely in such apertures so that the Shanks may move longitudinally to raise the hammers.

K, k, K', 1', K2, i, K3, 7c3, Kt, lo, are abutments which are respectively rigidly secured, as by screws or bolts L, to corresponding shanks or' the J, y', series.

lVhen any hammer is down the abutment of the H,vlt,. serieswhich is on the shank thereof, (being also down) is enga 'ed by the corres )ondiur abutment of the I., series asv such abutment aseeuds (see arrow adjacent to chain Cf* Fig. 2) and such abutment of the H, h, series, to ether with the shank to which it is attache and the hammer on such shank, is raised into substantially the position illustrated in Figs: 1, 2 and 3, of the drawings.
