UNITED STATES PATENT OFFICE.
THOMAS MITCHELL, OF' LANSINGBURG, NEV YORK.
MACHINE FOR `.BORING' BRUSH-BLOCKS.
Specification of Letters Patent No. 31,471, dated February 19, 1861.
T0 all whom it 'may concern:
Be it known that I, THOMAS MITCHELL, of Lansingburg, in the county Rensselaer and State of New York, have invented a new and Improved Machine for Boring Brush- Blocks to Receive Their Bristles; and I do hereby dec-lare the following to be a full, clear, and exact descript-ion of the same, reference being had to the annexed drawing, making a part of this specification.
Figure l is a side elevation of my machine. Fig. 3 is a vertical cross section taken in the line X X of Fig. 1. Fig. 4t is a view of one of the upright plates representing the holes as borings of the bits or mandrels. Fig. 5 represents a mandrel containing a bit on one end crank on the other.
Similar letters of referencev indicate corresponding parts in the several figures.
This invention consists in the construction of borings containing the number of holes and shape of the rows and circles corresponding to those desired to be made in brush blocks. In these holes crank mandrels containing bits are placed which are turned simultaneously by the movement of one of the plates connected with the cranks so that all the holes in said blocks are bored at once.
To enable those skilled in the art to fully understand and construct my machine, I will proceed to describe it.
A, represents a platform which may be made in any desirable manner.
B, is a driving shaft placed in the borings C, C, and secured to said platform.
D, D, are borings containing the number of holes, in rows or circles corresponding to those desired to be made in brush blocks, and constitute the patterns of the same, which is represented in Fig. 4L.
E, E, E, are mandrels containing bits a a a, one of which is represented in Fig. 5. b, I), b, are cranks formed on the ends of said mandrels or secured to them in any other desirable manner.
F, is a driving plate containing the corresponding holes with those in the borings D, D, and are borings for the cranks which revolve the mandrels. The outlines of said plate are represented in Fig. 3 in red lines in order to show parts back of the same.
G, Gr, are gearing wheels, each of which contain an eccentric pin c, c, upon which 'the driving plate F, is secured and give motion.
H, is a gear wheel attached to the end of shaft B, connecting with gear wheels Gr, Gr, thereby securing the same direction of the eccentric pins they contain respectively, pro-l ducing the uniform motion of the plate F. Upon the shaft B, is a worm I, for the purpose of securing a feed motion graduated to the velocity of the bits.
J, J, are gear wheels, which mesh in the worm I, producing uniformity of feed motion, the shafts standing vertical in the gear wheels J, J, have eccentrics or cranks d, CZ, represented in dotted lines on their lower ends, to which connecting rods K, K, are attached. These rods are formed with joints c, c, in their centers for the purpose of giving feed motion in borings f, f. The opposite ends of said rods are turned up at right angles, to which upright parts g, g, is attached a block L, and against which the work to be bored is placed.
The operation of the machine is as follows: A belt driven by any convenient power connected to the pulley M, on shaft B, so as to cause it to make about one thousand revolutions per minute, when the feed block reaches its greatest distance from the bits, a blank block is then placed vertically between it and the bits, and there left until it has been carried against and perforated by the bits, and removed to give place for another when the feed returns said block so as to clear the bits.
Having thus described my invention what I claim as new and desire to secure by Letters Patent is- The feeding apparatus as described in combination with the series of bits substantially and for the purpose set forth.
THOMAS MITCHELL.
