Description
" '3 FFE J. A. MCKINSTRY, OF MONSON, MASSACHUSETTS.
lMPRovEn/ie-NT IN Mireia-Boxes.
Specitication forming part ot'iLetters Patent No. 59,016, dated October' 23, 1855.
To alt whom t may concern:
Be it known that I, J. A. MCKINSTRY, of Monson, in the county of Hampden and State ot" Massachusetts, have invented a new and Improved Miter-Box; and l do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawings,forming part of this specification, in whicl1 Figure l is a plan or top view of my inven tion Fig. 2, a transverse vertical section of the same, taken in the line x w, Fig. l; Fig. 3, a horizontal section of a portion of the same, taken in the line 1/ y, Fig. 2.
Similar letters of reference indicate correspondin g parts.
This invention relates to a new and improved miter-box of that class in which the saw-guides are adjustable to admit of the moldings or other articles or stuff to be operated upon being cnt or sawed to any desired angle.
The object of the invention is to obtain a miter-box of the class specied which will be simple in construction, capable of having its saw-guides adjusted with facility and great accuracy, and also capablevof having said guides renewed without any difficulty when worn by use. v
The bed cf the device is composed of two parallel parts, A A', connected together in such a manner that they maybe moved or adjusted longitudinally. This connection is arranged in this particular instance as follows: The rear or inner edge of the part A of the bedpiece has a metal plate, B, secured to it by screws or otherwise, said plate extending the whole length of A, and the latter having a rabbet, d, made in its upper edge, which rabbet extends down a little below the upper edge of plate B to receive the lower part of a guide, C, which is attached to the inner edge, of the part A of the bed-piece, as shown clearly in Fig. 2. This connection, it will be seen, admits ofthe longitudinal adjustmentof the parts A A', and said parts are secured at any desired point within the scope or range of their movement by means of clamps composed of rods D D, which pass transversely through the part A', and are formed with hooks at their inner ends to catch over the top of plate B, the outer ends of the rods D having screw-threads out 0n them to receive nuts b, by screwing up which the two parts A A' may be clamped firmly together. (See Fig. 2, in which the clamps are chiefly shown by dotted lines.)
To the outer edge of the part A of the bedpiece there is secured a horizontal semieircular graduated plate, E, and in each part A A of the bed-piece there is inserted an upright post, F, which have saw-kerfs c made vertically iu them to receive the saw-blade and serve as guides for the same. These posts F are constructed of wood and are fitted on metallic uprights G, the lower portions of which are of cylindrical form and are tted in the parts A A of the bed-piece, and have pendent lips or lugs c', which extend down below the partsA A. The upper parts, ax, of the uprights G are made fiat and are fitted in slots in the posts.
(See Figs. 2 and 3.) These flat parts of the uprights are slotted vertically to receive the saw, said slots being sufciently wide to prevent the saw-teeth comin gin Contact with them.
By this arrangement it will be seen that the posts E may be readily detached from the metallic uprights and new ones applied vwhen necessary. This frequently is necessary, as the teeth of the saw graduallywiden the kerfs c c in the posts F, so tha-tthey will not serve as proper guides for the saw.
The two posts F,F are connected by meansA of a telescopic or expandin g. rod, AX composed of two parts, d d', which are attached to the lips or lugs c', the part d', which is attached to the lip or lug ot the upright G of one post, being tubular and receiving the rod d, which is attached to the lip or lug of the upright ot the other post. (See Fig. 2.) This telescopic or extension tube performs an important func tion, to wit: it connects the-two posts F F, and
in the adjustment of the parts A A keeps the the saw-kerfs c of the two posts F F in line with each other by causing the uprights Gr to turn simultaneously and equally in the same direction.
The guide C is notched or divided at its center, so as to leave a space, e, in line with the posts F F, for the saw to work through; and the molding or other article to be sawed is placed against the guide C and the parts A A moved longitudinally, so as to bring the saw-kerfs c c of the posts F F at the angle required for sawing the molding or stut'; and this angle, be it greater or less, is-obtained with the greatest facility and exactness by an index, H,'projecting from the upright G of the post of the part- A of the bed-piece, said index extending over the graduated plate E. (See more particularly Fig. l.)
When the parts A A are adjusted as desired, the nuts b, which were previously unscreued or relaxed, are screwed up, and the parts A A thereby rmly secured in position. The saw is then placed in the kerfs c 'c of the posts F F, and the molding or other article sawed or cut through at the proper or desired angle. Y
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
The miter-box the parts of which are composed of the adjustable plates A A', guide C, plate B, hooked rods I), graduated plate E, guide-posts F, uprigbts G, and expanding rod AX when arranged and operating substantially as described, for the purpose specified.
