CYRUS CHAMBERS, JR, OF PHILADELPHIA, PENNSYLVANIA.
SAND-SCRAPER FOR BRICK-MACHINES.
I SPECIFICATION forming part of Letters Patent No. 285.013, dated September 18, 1-313.
' Application filed February 8, 1883. (No model.) I
Be it known that I, CYRUS CHAMBERS, Jr., a citizen of the United States, residing at the city and county of Philadelphia, and State of Pennsylvania, have invented certain new and useful Improvements in SandScra'pers for BrickeMachines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.
. This invention relates to the scrapers or wipers that are used in connection with the sanding devices of the brick-making machines heretofore patented by me by several Letters Patent of the United States for the purpose of removing the surplus of sand from the continuous bar of clay, which sand is applied to the latter on its way to the cut-off mechanism.
It is designed to improve the construction and efficiency of these scrapers, as will hereinafter be explained.
Of the accompanying drawings, Figure l is a front elevation of a sand-box with scraperframe connected with the front or die end of a Chambers brick-machine having my improved scrapers attached thereto. Fig. 2 is a vertical section on the line a b, Fig. 1; and Fig. 3 is a horizontal section on the line 0 d.
B marks the sandbox, with its hopper H, secured to the front or die end of the brickmachine. The bar of clay (indicated, by the broken lines as, Fig. 2) issuing from the die D is coated with sand, which falls in a liberal supply from the hopper through the openings h, Fig. 3, at the bottom of the same. The scrapers R B have been made of thin pieces or sheets of india-r'ubber fixed in clamps, each having a guide-rod sliding in bearings, and provided with anadj ustable tension-spring and set nuts or collars, whereby, while the their proper scrapers could be readily adjusted to press more or less firmly against the bar of clay, they would yield in a direction at rightangles to the clay-bar-that is, to the direction of its motionwhen an obstruction was encountered or the bar of clay became unduly enlarged, and afterward be brought instantly back to and usual positions. Such scrapers are described in a certain application for Letters Patent executed by Sanford W. Lasor on the 1st day of February, 1883, and filed simultaneously herewith. Other styles of scrapers for a like purpose have been emtally, as shown.
ployed. My present invention is, however, more especially intended to improve upon the spring-tension scrapers of said Lasor just referred to. l
In the accompanying drawings, R are two side scrapers consisting of reversible plates of steel bolted onto arms 0, which are hinged to the scraper-frame A so as to swing horizon- These arms 0 are provided with vertical lugs or pins P, which serve -to hold an elastic rubber band, 0, by whose ac tion the armstliat is, the scrapers R are made to turn toward each other, in effect, to embrace the sides of the bar of clay passing on between them, and are permitted to yield when required. The inward movement is regulated and limited by means of set-screws S, which strike against the side of the scraperframe A, which frame carries all of the scrapers, and is hinged to the front of the hopper of the sandbox, as seen in Figs. 1 and 2., The object of thus limiting the inward throw of the scrapers is to prevent them from being proj ected too far in across the path of the bar of clay at the beginning, and thus obstructing the exit of the latter from the sand-box. A
top scraper, R, similar to R, and bolted onto an arm, 0, pivoted on each side of the frame A,'is used to wipe the surplus of sand from the top of the clay-bar. It is caused to press against the latter preferably by its gravity and that of the swinging frame which carries it Its downward throw is limited by a set screw, S, operating similarly to and for a like purpose as the screws S of the side scrapers. Now, it is seen that the edges of the scrapers will always be kept against the bar of clay by an elastic or yielding force, whereby they are enabledto adjust themselves at all times as The inner adjacent surfaces of the several scraper-arms O O and of frame A are correspondingly curved on the arc of a circle whose center is in each case the pin upon which the arm swings, so that whatever be the sweep or swing of the latter the joint between it and the frame A will always be kept as close as possible, and thereby prevent the escape of the sand or light dust from within the sandbox. This construction as to the top scraperarm, 0, is seen in Figs. 2 and 3. In Fig. 2 it will be observed that the arc in dotted lines, in which the edge of the scraper-blade It moves, is struck from the center of the pin 1), on which the arm G turns, and that the adjacent or contiguous parts of the latter and the frame A, forming, so to say, a part of the sand box, (at the point 2,) are also curved in the are of a lesser circle struck from the center of said pin.
Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. In combination with thesand-boX of a brick-machine, the hinged scrapers arranged with relation to the path of the bar of clay, as shown and described, and held to their work against the latter by an elastic or yielding medium, substantially as set forth.
2. In combination with the two side scrapers secured to the hinged arms, the elastic band 0, connecting the said arms, all combined, constructed, and operating substantially as and for the purpose described.
8. In combination with the scrapers R R, hinged to frame A, the set-screws or equivalent means for adjusting and limiting the inward throw of the scrapers, substantially as specified. 4. The hinged scraper-arms-and the frame A, combined as shown and described, with their contiguous surfaces curved in the arc of 0 a circle struck from the center of the are upon which the said arms respectively vibrate, as and for the purpose specified. I
5. In combination with the sand-box of a brick-machine, the reversible, self-adjusting, and swinging or swiveled steel scrapers for scraping off the surplus of sand from the bar of clay issuing from the die of the brick-machine, substantially as set forth.
In testimony whereof I have hereunto affixed my signature this 1st day of February, A. D. 1883.
