CEMENTING APPARATUS.

SPECIFICATION forming part 0f Letters Patent No. 532,645, dated January 15, 1895.

Application led March 30,1894. Serial No. 505,769. (No model.)

To @ZZ whom t may concern:

to the accompanying drawings, and to the iigures of reference marked thereon, Which form a part of this specification. Y

Our invention relates to apparatus for the applying of cement, either in heated or cold form, to such surfaces as can be coated with a brush, and in which a constant supply is provided for the said brush by special mechanism.

With reference to the accompanying drawings: Figure 1 representsl a side view of the apparatus, partly in perspective or elevation and partly in section. Fig. 2. represents an enlarged sectional view of the worm or screw shown in Fig. 1.

In each View the same figures represent the same parts throughout.

1 represents the reservoir into which the cement is placed and which is heated by some simple device when it is so desired. This reservoir is placed above an elongated cylindrical chamber 2 and is fastened to the same at collar ilanges 3. The elongated chamber 2 rests upon a pedestal 4, which latter is firmly fastened to a bench or table by

bolts

5, 5. The chamber 2-also is provided at one end with a hole 6 which is a bearing for the shaft 7 at its journal 7 The end of the said journal 7 which extends outside of the chamber 2 is fitted with a grooved pulley 8, this pulley being for the purpose of transmitting a circular motion to the shaft 7. The other end of the shaft 7 is also provided with a journal. 9 which, rests in a hole in the end plate 10,'this latter being firmly fastened to the cylinder 2 by set screws l1, 11.. This end plate 10 has fastened to it or is integral with a small cylindrical chamber 12, the latter being provided with

outlets

13, 13, in any number that may be desired, and to which outlets are attached iiexible tubes 14, carrying applying brushes 15 which may be held upon support 22.

The shaft 7 has about it the Worm thread 16, which beginning near the pulley end of the said shaft, ends near the other end thus forming a Worm or screw. This worm or screw fits snugly the chamber 2, and in its rotation carries whatever may enter the said chamber from the one end to the other. The shaft 7 at its end opposite the pulley is peculiar of construction. It contains a chamber 17 which opens into chamber 12 through a passage in journal 9, and which communicates with chamber 2 through holes 18. At a point in the upper wall of the chamber 2, and between the extremity of the worm thread 16 and the end plate 10 a passage leads through the said wall, through the tube 19, and into the top portion of the reservoir 1. Stop cocks are placed in the tube 19 at 20, and in the flexible tubes 14, as at 2l.

We will now describe the operation of our apparatus, and will then define our invention in the claims hereinafter to be made.

Cement inl any desirable quantity is placed in the reservoir 1, and as has alreadybeen stated, may if desirable be heated. By following the course of the arrows, it will be noticed that the cement passes by its own Weight into the chamber 2 and is engaged byY vthe worm or screw thread 16 and pressed forward, such power being derived from the pulley 8 which revolves at a desirable speed. When the cement reaches the end plate v10, it can follow two paths, viz: enter the holes 18, chamber 17, pass through shoulder 9 into chamber 12, and from thence be distributed through the iiexible tubes 14 to brushes 15 and to the work; or the alternative path which the cement may follow is to enter tube 19, and pass again into the reservoir 1. Stop cocks 21 regulate the liow of cement at the brushes 15, and the one at 2O regulates the return flow of cement to the reservoir 1.

Having described our invention, what we claim as new, and desire to secure by Letters Patent, is'- Y 1. A cementer comprising a cement tank IOO 2. A feed mechanism for cementers, com- I prising an elongated cylindrical feed-chamber, a revoiubly journaled worm fitting the same, a chamber in one end of such wormshaft, openings from lche feed-chamber to the shaft-chamber, and an axial passage in one journal from said shaft-chamber, substantially as described.

In testimony whereof we affix our signa- :5 tures in presence of Witnesses.
