@statewide Letters Patent No. 97 506, dated December 7, 18H0 4 i IMPROVEMENT INv BORING-MACHINE.
The Schedule referred to in these Lettere Patent and making part'of the same.
To all whom t may concern.:
Be it known that 1, JOSEPH HAMrsos, of Newburg, in the county of Orange, and in the State of New York, hsve invented a new and useful Machine for DrillingShutterfStiles, or any similar pieces of work'g, and I, do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawing, and to the letters of reference marked thereon.
The nat-ure of my invention consistsin the arrange- 'ment of a number of `drill-spindles, with inserted bits in a plane, in such a manner that they all at once can be set in a rotary motion, and, being equally distanced between centres, can be kept stationary during working time, `but ,which distance between centres can be. changed simultaneously on all spindles, without setting or adj nsting every single spindle, according to the work to be` done, in this way saving much time re` quired' for laying out and drilling every single hole Separately, in blind-Stiles or' similar work.
lTo betterunderstanding, I refer to the annexed drawings, in which" i Figure l is a plan of the whole machine.
Figure 2 represents a cross-section of the machine, showing especially the side view of a spindle-headstock.
Figure 3 is a cross-section of a pair of those spindlehead-stocks, with spindles.
AA represent the bed-frame `of the drilling-machine, and is so arranged that the head-stocks B B oi' the spindles C C are held down to thei'r'ame by means of two V-shaped grooves, but are allowed to slide sidcways along in these grooves, if needed.
A sufficient number of those head-stocks 'B B is placed on this bed-frame, each one carrying a spindle, C, in suitable bearings at each end.
These spindles() C are set in rotary 'motion by a worm-screw, E, gearing into the small worm-wheels 'E F, on each spindle (l, and which is driven by a belt running on pulley K.
The spindles (l C are 'all alike, and their ends are all in line. 4
The bits DD, inserted in` those spindles, are all of the `same length, and therefore a piece, P, representing a lblind-stile, pressed even against the bits when they are revolving, will be drilled with holes of the saine depth, size, and distance apart, ready to receive the tenons of the slats. i
rlhe spindle-head-stocks B B are all made of the same Width, so that they carry the spindles, when packed close, side by side, the same distance apart, from centre to centre, and as close together as ever will be required to drill holes in blind-Stiles; but, as the slats are not all of the same width. 'and are not all set evenly apart in different shutters or blinds, it is necessary to set the centres of the bits according to the distance the holes for the tenons of the slats want to be, and this isv done by the following mechanism v In each head-stock, B B', are screwed in two brass bushes, N N, some distance apart, with a square hole through their centres, for a square rod, G G', to pass through.
Each bush N into a corresponding countersink, o, in the body ot' the head-stock, so that the bnsh'will not project over the sides when screwed home, and will therefore allow those head-stocks to be placed close together.
The thread on those bushes N is alike on all, and the square hole is standing alike iu all, when in their places, so that the square rods (lr G can be pushed through from one lend to the other, without turning a single bush. l
The shoulder u of the one bush covers the smaller end of the bush next to it, and for this reason, when both rods G G are turned simultaneously, all bushes will unscrew alike, and-will push the head-stocks ll B', with the spindles C C, the further apart, the more the bushes are serewedout of their places. Are the rods G turned the other way, the bushesN are screwed in again, and allow the head-stocks to hc placed closer together again.
`On one side of the bed-frame A is placed a stud, tov carry a pinion, M, and a hand-wheel, L, the pinion to gear into two equal wheels, RUM, which are fastened to the square rods G i. is turned, thebushcs N are turned either one way or the other, but all alike, and the distance of drill-spindles is easily regulated.
To keep the spindles steady when once set right, a hole is drilled about in the middle oil each headstock for a bolt, H, to pass through. This bolt H also passes through one side of the bed-frame A, and carries a hand-wheel, Hz, on its end, in 'which' wheel is cut thread, and which acts like a wing-nut on the bolt.
The head Hl, ot' the bolt H, lies behind the last head-stock, and whelrthe wing-nut Il is screwed up tight, the bolt keeps all the head-stocks closely bollini together, and they can only be set further apart after loosening the nut so that the bolt gives more room between head. and nut to be taken up by the headstocks, by spreading them apart, which is done by turning wheel L in the right direction. Are the spindles to be placed closer together, the wheel L has to be turned the other way, and the nut HZ screwed up more on the bolt 'H until the head-stocks are held tight in their places.
A suitable table is arranged to the bed-frame Ato has a shoulder, n, on one side, to tit When the hand-wheel L v curry the work to be drilled, and move it; evenly against the bits, so that the holes will come straight, und of even depth. n
A large amount of labor is saved by using this'machine, especially in factories where much blind work is done.
\Vlmt'I claim :is my invention, and desire to secure by Letters Patent, is-
1. The bushes N N, wit-l1 shoulders n n, in oombinution with rods G- G', head-stoeks B B', gearingM1 M2 M, ond hand-wheel L, for altering simultaneously the 'distance between centres of the drill-spindles O C, as specified.
2. The bolt H, with heed H amd wing-nut H2, in combination with the head-stocks B B', for holding the spindles stationary, when sei', right for use.
3. lhe drilling-machine, composed of frame A, spindle-head-stocks B B, revolving spindles O C, with bits D D, rods G G', with bushes N N, gearing M1 M2 Mhand-wbeel L, bolt H H1, with nut H", all combined for t-he purpose as specified.l
