SPECIFICATION forming part of Letters Patent No. 297,675, dated April 29, 1884.
Application filed December 26, 1883. (N0 model.)
To a-ZZ whom it mag concern.-
Beit known that-I, GYRUs CHAMBERS, J r., 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 Clay Tempering and Expressing Devices for Brick-Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings. 7
. Figure l is a side elevation of the tempering-knife shaft and the conoidal expressingscrew on the end of the same, all the knives save the first three adjacent to the screw having been removed. Fig. 2 is afront end view of the said shaft with all the knives in position, the screw having been taken off. Fig. 3 is a view of the screw detached, looking at its rear end, or that next to the shaft. Figs. 4 and 5 are diagrams illustrative of a certain difference between my present and previous arrangements of the tempering-knives upon the shaft.
This invention is an improvement in devices for a like purpose that have been used in the brick-machines patented to me by various Letters Patent of the United States such as No. 207,343, of August 27, 1878, and No. 275,467, of April 10, 1888, and other patents previous to the foregoing for brick-machineswhich have gone largely into use, and have been well known for some twenty years last past as the Chambers Machine.
The object of the invention is to improve the operation of said tempering and expressing devices through a new arrangement of the tempering-knives with relation to each other and to the expressing-screw.
The invention also consists in a more convenient mode of fitting the screw upon the end of the knife-shaft. I
As shown in both of said patents, the knives are arranged around the pugging-shaft in a spiral winding in a' direction opposite to thatof the spiral of the screw. The special advantages of that arrangement of the knives arerecited at the bottom of page 2 and top of page 3 of the specification of the patent of August 27 1878, and I retain; that relative arrangement of the spirals in the present device.
- nate turns.
A reference to Fig. l of the drawings ac companyin g said. Letters Patent will show that the knives constituting the successive turns of the spiral are arranged upon the shaft, as taken longitudinally, in a series of straight lines -that is to say, the arrangement'is such that if a series of lines be drawn from one end of the shaft to the other through the longitudinal rows of knives each of these lines will touch a knife in every turn' of the spiralwhile by my present improved arrangement the knives are staggered that is to say, if similar longitudinal lines be drawn as those just mentioned, they will touch a knife only in every alternate turn of their spiral.
A comparison of the diagrams, Figs. 4 and 5 of the drawings hereunto annexed, will show the difference between the old and the new arrangements, respectively. The small dots or circles therein represent the knives, the lines o d the spiral, and lines a. 1) those drawn lon-' gitudinally with the shaft through the knives.
It will be observed that in Fig. 4 the lines a b toucha knife in each turn of the spiral, while in Fig. 5 they touch only knives in alter- The latter construction is further shown by Fig. 2, wherein the knives (twentyseven in number) are numbered in succession, following the curve of the spiral around shaft A, beginning with the knife (1) nearest the screw, and ending with the one (27) at the "other extremity of the shaft.
The advantage resulting from this arrangement consists in the securing of a comparatively greater space between the knives upon the longitudinal lines, and yet have quite as many, and, in fact, more, knives as heretofore upon the shaft. Thus the clay between the knives has ample room, the amount of friction is diminished, and the clayis prevented from liability of lodging between the knives.
Referring now to Fig. 1, it will be seen that the knife marked 1that is, the first knife of the spiralis placed as on a continuation of the spiral flange of the screw S, some distance beyond the latter; also, that the knife 2 is 10- cated to the left and in advance of the end of the screw. By this relative arrangement of these two knives and the rear end of the screw, sufficient space is left between the first knife and the opposite side or flange of the screw for the clay advanced by said knife to enter between it and the screw, and ample space is left between the second knife and the mouth of the screw for the body or furrow of clay advanced by both the first and second knives to easily enter the mouth of the screw without undue packing or jamming of the clay.
In order to insure the connection of the screw to the end of the knife-shaft always in the one proper position with relation to these adjacent knives, I provide the socket O in the rear end of the screw with unequidistant projections or lugs b, Fig. 3-three in number in the present instan cc. These lugs coincide with grooves b in the forward end of shaft A, into which the former enter when the screw is forced upon the shaft until stopped by the shoulder thereon. Ihe grooves and lugs are of course located in the suitable relative positions for securing the desired result. In this way the screw will be rotated by and with the shaft, and it will be impossible for an error to be made in placing the screw in position.
I claim 1. In combination with the shaft and screw, the knivesarranged upon said shaft in a spi-' ral running reversely to the spiral of the screw 30 and staggered longitudinally, in the manner and for the purpose specified.
2. In combination with the screw and the knives arranged on the shaft in the manner shown, the first two knives located with rela- 3 5 tion to each other and the screw, as and for the purpose specified.
3. In combination with the knives andtheir shaft provided with the unequidistant end grooves, the screw having the socket, with 40 lugs corresponding to said grooves, substantially as and for the purpose specified.
4. In combination with the pugging-shaft, the tempering-knives arranged thereon in a spiral, and staggered, as and for the purpose 45 specified.
In testimony whereof I have hereunto affixed my signature this 18th day of December,
CYRUS CHAMBERS, JR.
