.`IMPROVEMENT "1N `lvrecnrum Fon THE MANUFACTURE or yvv'ooDEEr TRAYs.
. f l j F The Schedule referredt'o'intthesa Letters Patent and making part ci the same.
`Beit known that I,OHARLEs HENRY DANA, of
West Lebanomof thefcounty of Grafton, and State'V l of New Izampshire,` have made a new and useful inf vention,'having,.reference tothe manufacture of Wooden` Txays ;``and do hereby declarethe-same to be fully described'in `the following specication, and
f represented in the accompanying drawings, of whichy Figure 1 is a topviewof the machilvieryused by me for performing the sawingof a block of wood for conversion of it into-a tray; Figure 2`is a side elevation; and Figure 3, a longitudinal section of suchmechanism. y Figure Ll: is an under-side view ofthe reciprocating saw-carnage. y .y y y 1 Figure 5 is a transverse section, taken through the plane circular saw used in making the sides of the int'erior of the tray. l
Figure 6 isa top view; Figure 7, a side elevation Figure, an end view; and -V l yFigures 9 and 10 arel sections ofthe concai-'o-convex cutter or chisel, usedfor separatingr from the sawed blocks the portionfnecessary tothe Vremoved for lthe formation of the hollow of the'tra'y.
'I would remark that wooden bowls lmay be made by the machinerto be hereinafter described.
The inode or process of making a' tray by themachine hereinafterdescribed, is analogous to that described in `the United States Patent No. 13,169, although there are differences between the two.,` My
invention hasreference--to `the machine inwhich the spherical concave-convex cutter has a rotary motion in one directiononly, it not having an orbital motion gwhile inrevolution, as is the case with the 'spherical cutter shown in such patent. In my machine the block has a circular movementwhile being cu-t.4 Thus it will be seen that there 4are distinctive featuresyof y difference between the twomachines.
In such of the drawings as the same may be shown` A` denotes `the machinery. y l y This frame supports, in suitable bearings, a aahor izontal shaft, B, provided with a driving-pulley, b.
Ou one. end of the said shaft there is `fixed a concavofconvex saw, O, which is'the segment ofahollow frame of the end and side-suwl'lg l sphere, the teeth beingcut in its periphery.
The shaft also `carries a` plain circular saw, D, the
l two saws' being arranged` on it in manner as represented. y i
There isa p latfbrm `or shelf E, extended from the From this platforniapivot,`c, is projected upward into a slot, d made in the. base of a poppet-head or carriage F.
A dat plate or abutment, e, is raised vertically on the .base of the carriage-andis to operate with a clamp-screw, f,'y(screwed through a. post, y,) in holding a block of wood to,the carriage.
The said carriage has two curved grooves h i made in its bottom or base, and arrangedwith respect to the slot d, in manner as represented in iig. 4.
Either of such grooves is to receive a stud for projection, k,extended np from a shelf or platform, E,
and arranged therein in manner shown in the draw,-
vmade in a platform, nl, which rests on the top of the 'l frame A, and is hinged to it, the hinges being disposed as seen at 1J. y I
Elevated on this platform is a vertical guide or ledge, q,and an inclined guide or ledge, r; the two being disposed on opposite sides of the kerf or slot o', and wit-h respect to. the platform G, in manner as rep; resented. x
In usingthe machinery above described for making a tray, the` block from which it is to be cut being trapezoidal, or thereabouts,ir 1 transverse section, is.. to be placed with its larger base against the abutment e and the stop n thereof, and held firmly to the former by the clamp-screw f. Next, the saws being supposed to be in revolution, the carriage is to be pressed endwise, so Aasto bring one end of its slot d closely against the pivot c.
the dished or spherical saw to cut into the block, so as to form the exterior rounded surface of one end of' the tray, after which the carriage should be moved back, and next, moved endwise, seas to .bring the other end of itsslot up tothe pivot. 'Y This done, the carriage should be again turned on the pivot, so as to cause the spherical saw to 'againcnter the block, so as to cutthe hollow cf'one end of the tray. The block should'next be turned over within the carriage and fixed tothe abutment, after which, its other ,end should be twice sawed into, in manner as was explained with reference to its first end. Next, the block is to be transferred to the platform G, previouslyelevatd Next, the carriage should be i turned horizontally on the said pivot, so as to cause above the circular saw, the larger base 'of the block being made to rest on the inclined surface of the ledge fr, and with the block also resting against the upright ledge or guide q. Next, the platform should be depressed, and the block be moved from one to the other of two stops s t, projecting from the face of the ledge 0', the whole being to cause the circular saw to cnt into the block from one of the spherical cuts to the other, so as to form one side of the hollow of the tray. A
y The other side. of the said hollow is next to be made by the same means, in a similar way, i'vhenit will be found that the tray, at its bottom, will still be connected with the remainder of the block. To septhe finishing or smoothing of it being subsequently performed by suitable means.
I make no claim to any thing or things, combinations, or arrangements, as described in either of the United States patents, No. 13,169, 94,592.
I claim as my invention the following, that is to say:
l. In connection with the spherical saw C and the rotary carriage 11, the slot d, the pivot' c, the guides h i, 7c, and the stops l m, arranged as described, the whole being to enable the said carriage to be moved and arrested relatively to the saw, substantially as and for the purpose as described.
2. The arrangement and combination of the single shaft B, with the circular and spherical saws O D, the
pliances substantially as described, for holding and guiding a'block in the ways and under circumstances as set fort-h. I
