UNITED sTATEs PATENT oEEIoE. i
THOMAS MITCHELL,` OF LANSINGBURG, NE\V YORK. *i
MACHINE FOR 'BORING BRUSH-BLOCKS.
Specification of Letters Patent No, 26,778, dated January 10, 1860.
To all whom 'it may concern:
Be it known that I,'THoMAs MITCHELL, of Lansingburg, in the vcounty of Rensselaer and State of New York, have invented a new and Improved Machme for Borino' Brush-Blocks to Receive Their Bristles; and I do hereby declare that the following is a full, clear, and exact description of 'the same, reference being had to the annexed drawings, making a part of this specification, in
Which- Figure 1, is a side sectional view of my invention taken in the line a2, a2, Fig.. 2. Fig. 2, a horizontal section of the same taken in the line y, y, Fig. 1. Fig. 3, a detached transverse section of a brush-block.
Similar letters of reference indicate corresponding parts in the several figures.
This invention consists in the employment or use of a polygonal drum having the brush-blocks attached to it and so arran ed as to have an intermittent longitudinal s iding movement, an intermittent rotary movement, and a reciprocating movement, said drum being used in connection with drills substantially as hereinafter described, whereby the blocks may be bored very expeditiously anda considerable number operated upon simultaneously or atthe same time. Y
` To enable those skilled in the art to fully understand and construct my invention I will proceed to describe. it.
A, represents a platform which is supported at a suitable height in any proper way, and B, is a driving shaft which is placed in suitable bearings a, on said platform. This driving shaft B, has a crank pulley Z), ateach end of it and these crank pulleys are connected by rods c, c, to slides C, C', which are fitted on ways el, (l, said ways being secured longitudinally on the platform as shown clearly in Fig. 2.
D, is a shaft which has its bearings in the slides C, C, and is allowed to turn freely in its bearings and also to slide longitudinally therein. On this shaft D, a polygonal drum E, is placed and also a cylinder F, the latter being attached to one end of the drum E. To the periphery of the cylinder F, racks are attached longitudinally at proper distances apart. Thesev racks are provided with ratchet-shaped teeth, and the teeth of one rack have a reverse position to those of its adjoining racks; the alternate racks f, having their teeth coinciding with Y each other in position, but in a position re verse to the first named racks. This will be fully understood by referring to Fig. 2. The racks f, g, do not extend the full length of the cylinder F, a space lt, is allowed at one end of each, .the racks f, allowin the spaces at one end of the cylinder an the racks g, allowing the 'spaces at the opposite en To theslide C4, on its upper surface a curved and grooved bar h, is attached. 'The sha e of this bar is clearly shown in Fig. 2, an intothe groove of bar h, a pin is fitted isaid pin being attached to the outerpart of a bar G', which is fitted in a uide j, and allowed to slide freely therein. o the inner end of the bar G, a plate H, is attached at right angles and this plate engages with the uppermost rack on the cylinder F.
To the slide C', a bar I, is attached horizontally. This bar I, projects inward toward. the cylinder F, and its inner end k, is bent at right angles to its main. rtion, said end lo, fitting between the racks On the platform A, two heads I are secured, and in these heads mandrels l, are placed, said mandrels having ulleys m, on them around which pulleys lts n, pass, said belts also passing over drums o, o, in the upper part of a framing J, which is placed on the platform A. In the inner end y of each mandrel l, a plate p, is placed.
vAround the shaft D, a belt K, is wound, said belt passing over a roller L, in the upper part of the framing J, and having a weig t M, attached to its lower end.
The operation of the machine is as follows: A brush-block r, is secured in any proper way to each face of the polygonal drum E, and the shaft D, is turned so that the weight M, Will be fullywound up, the weight touching the under side of the platform A. The shaft B, is then rotated by any convenient power and the drills p, p, are rotated from said shaft bymeans of the beltsn, n, and nx. A reciprocating motion is given the slides C, C', and consequently the shaft D, by means of the connecting rods c, c, and crank pulleys b, b. By this reciprocating movement the blocks 7', are presented to the drills p, p, and a hole is drilled in the blocks r, opposite the drills at each movement of the shaft D. The drum E, is shifted orv moved longitudinally at each feed move ment or stroke so as to space properly between the holes, by means of the plate H,
A the end of the rack above it and the weight M, will rotate the drum E, a distance equal to the space between the racks, the bar I, servin as a stop and preventing the rotation o the drum E, except at the proper time, the racks determinin the distance of the rotary movement'of t e drum. Each time the drum E, rotates a fresh surface of the blocks 1", are presented to the drills p, and a succeeding row of holes bored, the drum E, being moved longitudinally in a direction opposite to that in which it moved before in consequence of the plate H, engaging .with a rack having its teeth in a reverse position to those of the preceding rack. The succeeding rows of holes is then bored and when finished the drum E, is again rotated the same distance asbefore, the drum moved longitudinally in an opposite direction and another row of holes bored; the operation is thus repeated until the'blocks 1', on the polygonal drum E, are all bored.
From the abovedescription it will be seen that the rotary movement of the drum E, determines the distance betweenthe rows of holes while the longitudinal movement of said drum caused by the racks f, g, and
plate H, and bars G, h, determine the length of the spaces between the holes in the rows. It will be seen also the length of the spaces between the holes inthe rows may be varied as desired by varying the form -of the grooved bar h, and the width of the spaces between the rows of holes may be varied by attaching agreater or less number of racks to the periphery of the cylinder F.
In consequence of presenting the brushblocks 1', to lthe drills p, attached to the faces of a lpoly yonal 'drum E, as shown and described, t e holes will be boredv from an oblique to a right angular direction in the blocks 1', as shown clearly in Fig. 3, the central row being at right angles with .the face of the block 1", and the rows each slde of 1t having oblique positions. This result 1s due to the varyingpositions the blocks 1', assume in being presented'to the drills p, and will be fully understood b referring to Fig. 1.
I would remark t at the length of the racks correspond with the length of the rows of holes, and in oval brushes the racks will of course be of varyin lengths as the rows of holes will vary in ength in order to be embraced within an oval. v
The drum E, ma be provided with any suitable number o faces or sides and it may be made of any suitable length so that several blocks'1', may be attached to each face, side b side, a corresponding number of drills b elng employed.
Having thus described my invention what I claim as new and desire to secure by Letters Patent, is-f 1. Attaching brush-blocks 1', to the faces of a polygonal drum E, having an intermittingly rotating movement an intermittingly ongitudinal sliding movement, and a reclprocatlng feed movement in connection with rotary drills p, p, one or more for the `purpose of boring the blocks to receive their bristles.
2. The arrangement of the racks f, g, on the cylinder F, plate H, bar G, connected with the grooved bar h', the stop barI, and slides C, C', `o erated as shown and having the shaft D, o the drum and cylinder tted in them with weight M, attached for givin the necessary movements to the polygona drum E, for the purpose set forth.
