TO ALL WHOM IT MAY OONCERN:
Be it known that I, CHARLES R. LONG, of Louisville, in the county ed? Jefferson, and State of Kentucky, have invented a new and improved BoringMachine; and I do hereby declare that the following is a full, clear, and exact description thereof, which'will enable others skilled in the art to makc and use the seme, reference being had to the accompanying drawings, forming part of this specification. I
Figure 1 is a transverse vertical section ofmy machine, through the line ze, iig. 2.
Figure 2 is a plan view of themachine.
Figure 3 is a cross-section through the line y y, iig. 2.
Similar letters ofreference indicate corresponding parts.
A .This invention is designed more particularly for boring chnir-stu`, but is fplillcable for other purposes, where several holes are to be bored at one operation. I H
It consists of thc mechanism now to be described, by reference to the drawings, in which the general frame i oflthe machine is shown at A. The three pulleys, a a a, are nur .ated onshafts, b If b,which have bearings in journals d d d, as shown. The journals d' are rigidly ailixed to the top" oi' the frame A, as shown, but the journals d d areiudixed firmly to movable beds, B B, as shown, the said beds slidingon'the top of the frame A, and guided by-a raised bead or rib, z', on which the beds B fit with in'ishedv contact of ka groove in its under side. Adjnstinglscrews m, having bearings inthe frame, as shown, work veach in u hollow thread formed in the.
end of its respective bcd'fB, as shown, and serve to adjust the lateral bits or angers e to or from the middle bit e,by moving the said beds to or fro on thetp of the frame A of the machine. These screws are turned by means of the wheels F ,keyed on them. The bits are 4held in sockets, ff f, aixcd to or forming part of the pulleysl1aft b 6, `b respectively. Y' l Counter-pulleys a( a are mounted on conntershafts .6 6,.hav-ing bearings d d in the under part-of the top of the frame, as shown. These pulleys are located under the space between the upper pulleys, as shown,
rand are for the'purpose of obtaining the rotation of the nppenpulleys in the same direction, and in a simple and eective manner, and also to enabl'e the lateral pulleys a a with their bits e le, to be adjusted to or fro within any reasonable li'mit, without materially tightening or.y loosening the belt, which passes in contact with all the pulleys, including the large pullv, D, located -on a. shaft, g, which has bearings in the lower middle part of the frame A, asshown.
i The shaft g of the lower `pulley projects beyond the frame,us shown, and upon the said projecting part is keyed a pulley, E, by which a belt from thc power drives the machine.
The beds B are clamped firmly at any point of their truvelby'clamp-screws h, as shown, which are hollow screws working upon screws n, projecting from the beds downward, through slots in 'the beds, as shown at '11.
On the front of the Eremo A are two guides, k, on which the apron-frame G works, by means of grooves, as shown. .This apron-frame is raised or lowered by the wheel and screw N and P respectively, the latter working lin a hollow thread in the yoke I, adixed to theapron-frame G, 'as shown.V
Clamp-screws, J, similar to those shown atl, work o'n screws passing through slots in the fram'eA, serving to clamp the apron-frame firmly at the d csirjed height. An apron, M, Vis provided on its under side with guides, o, which't with smooth contact against the similar guides, r, Iforming part of the apron-frame G. This apron is for thc purpose of holding the chair-'stuff or .otliet material to be bored, and is provided with lugs l, as shown, for the-purpose of holding the wood rmlywhile the apron is moved up to the bits, for the said apron ismovable to and from the bits by means of the guides e and r aforesaid. Adjustable plates, w, limit the forward' movement of the apron. A stad', p, is pivoted as shown,
and its lower end terminates in the slotted segmental plate q, whereby it may be clamped irmly to the arm, q",
projecting from the apron M. This device applies more particulnrly to the boring of certain parts of chairs, as the two `front legs and the two back legs, which must be bored at a certain angle, the front legs being, as genernlly made, wider apart than the back legs, so that when the front legsare driven together on the front rounds,
s1 est they are rested upon the apron and against and' erosswise of the staffp, which must bc set forvyard or at an acute angle, the apron supporting the leg-which is being. bored. The holes will then be formed so as to correspond with the greater width of the rontJegs.
The steif must be set a corresponding distance backward, or at :an obtuse angle with the apron, when the buck legs are being bored. This device enables the holes to be bored with precision and uniformity, whereby the parts canbe driven together -without diiliciilty or the springing of the rounds, as is-frcqucntly 'the case when the holes ure bored separately, as heretofore. l have had this machine in practical use for many months, and it has been proven to possess the following advantages:
First, in the manufact-uro of chairs, it willaecomplish at least three times more' work, and with more accumcy, than the boringmaohines heretofore used. l
Second, the work caribe driven together with double the rapidity of that boied by other machines.
Third, it is adapted to all kinds of boring, wlw-a tho holes are to bo in line with euch other, and sulciently approximated.
Fourth, it can be attended by unskilled operators, thereby dispensing with higher-priced labor than is required by other machiues.
' Fifth, it is simple, cheap', and not liable to get out of order.
The number of bits may be increased by the uddition of two or four more bit-shafts and pulleys, and also.
the corresponding counter-pulleys, without objection.; If desired, the upper pulleys may not be in the sume horizontal line.
Iclaim as new, and desire to secure by Letters Patent- 1. The arrangement of the sliding beds B Badjusted with reletiony to the fixed central shaft b' audits pulley, from opposite ends of the frame A, by menus of the screws m, constructed to operate ns herein described,
for the purpose specified.
2. The stal`-p, constructed und operating substontaily as shown and described, in combination with the apron M of a; boring-machine, ull as and for the purpose set forth.
