Description

March 17, 1925- R. P. M. DAVIS MOLD CLEANING DEVICE Filed Oct. 4, 1922 Patented Mar. 17, 1925.
UNITED STATES PATENT OFFICE BOY 2. 1s. DAVIS, 01 IOUNT UNION, PENNSYLVANIA.
xomcnmnwe DEVICE.
Application fled October 4, 1923. Serial No. 598,225.
To all whom it may comm:
Be it known that Ror P. M. DAVIS, 11. citizen of the United States of America, residing at Mount Union, in the-county of Huntingdon and State of Pennsylvania, has invented certain new and useful Improvements in Mold-Cleanin Devices, of which the following is a spec' cation. 1
My invention relates to cleaning devices for molds and more articularly molds used in brick making mac ines'.
In making brick, it frequently happens that considerable quantities of the mud or material from which the bricks are made will adhere to the bottom plate of the mold after the brick has been removed therefrom This adhering material interferes with the making of a perfect brick and it is the ob ject of the present invention to obviate this objectionable condition.
In the accompanying drawings forming part of this specification:
Figure 1 is a plan view of the brush;
Figure 2 is an end view of the brush;
Figure 3 is a section on the line 3-3 of Figure 1, and
Figure 4 is a detail view showing the key connection between the sleeve and shaft.
Referring more particularlyto the drawings wherein like reference numerals refer to corresponding parts throughout the several views, 1 denotes a base upon which are mounted tracks 2. Slidably mounted on the tracks 2, are bearing blocks 3, which support the ends of a hollow brush shaft 4.
The brush 5, is fixedly mounted on a perforated sleeve 6, keyed for sliding movement upon the hollow brush .shaft 4, the perforations 7, in the shaft 4, bein adapted to register at times with the per orations 8 in the sleeve 6, as will be more fully explained hereinafter. A flexible hose 9, is loosely connected to the end of the hollow shaft 4, and is held against turning movement with the shaft, by means of an arm 10, on the base 1. This hose is connected to any suitable source of steam or com ressed air supply (not shown). Any suitable mechanical means (also not shown) is employed for moving the brush shaft and brush carried thereby to and fro upon the tracks 2, or if desired this may be done by hand. It will be understood that the mold 11, shown in outline in Figure 2, will be suitably positioned in inverted positlon above the brush shaft, and in the path of movement thereof. Rotary movement is imparted to the brush shaft and brush by means of a sprocket and chain drive 12, connected with any suitable source of power (not shown).
In addition to the rectilinear motion of the brush just described, the brush is given a vibratory motion in a direction parallel to the axis of. the shaft on which it is mounted. The sliding sleeve 6 upon which each brush 5 is carried is formed at one end with a cam groove 13, in which seats a roller 14 on the end of a finger 15 attached to one of the brush bearing blocks previously described. As the brush is rapidly rotated by the sprocket and chain drive previously described the action of the roller 14 shifts the sleeve and consequently the brush very rapidly to and fro along its shaft, thus imparting a more or less vibratory movement to the brush, coil springs 16, on the opposite end' of the brush shaft helping to hold the brush firmly and prevent chattering thereof.
In operation the mold having been filled with brick making material and thebrick formed therein, the mold is inverted and the brick ejected therefrom. The rapidly rotating shifting brush is then moved along the tracks 2, as by means of a handle 20, and the steam orcompressed air being turned (in, adthorough cleaning of the mold is efecte It will of course, be understood that certain of the perforations in the brush shaft, sleeve and brush come into and out of register intermittently. However there will-be at all times sufiicient of the perforations in register to produce a practlcally uninterrupted flow of cleaning fluid.
The use of the steam or air has proven very effective in actual practice, and where certain brick making material is employed in the mold the rotatin and shifting of the brush may be entirely ispensed with.
Having thus described my invention what' I claim 1s:
1. In an ap aratus for cleanin brick molds, means or brushing the mo d comprising a shaft, a sleeve keyed for slidingv movement on said shaft, a brush fixed to said sleeve, means for moving said shaft across the face of the mold, means for rotating said shaft, means for reciprocating said sleeve on said shaft, and means for feeding a charge of cleanin fluid under pressure to said brush while e brush is in motion.
2. In an apFaratus for cleaning brick molds, a pair 0 tracks, a shaft mounted for movement on said tracks across the mold, a sleeve keyed for slidable movement on said shaft having a cam groove therein, a brush on said sleeve, means for actuating the shaft to move it across the mold, means for rotating the shaft, a finger bodily movable with said shaft engagin in said cam grooveto cause the sleeve an said shaft as said shaft is rotate 3. In an apparatus for cleaning brick molds, a rotating hollow brush, means. for
brush to recilprocate on causing said brush to move across said mold, means for imparting a transverse movement 15 to said brush with respect to the mold, and means for feeding a charge of cleaning fluid under pressure to said brush while said brush is in motion.
In testimon whereof I aflix my signature 20 in presence 0 two witnesses.
