YiirunovelinlzN'r.IN MACHINES Fon MAKING FAn-STICKS.

To all persons to whom thse presents mag/come:

Be it.kuo vn that 1, Vlrllalrnjnl) S. HUNT, of Weymouth,-1n the county ot'Norlfolk and Stateof` Massachusetts, `have inventada new andisefulMaohinehr Molding Fan-stCkBlOCks; and `1 A do hereby declare the sametobe fully described inV thefhllowifng specification Land `represented in fthe. 'accompanying drawing, of'which- 'l r Figure l is a top view,

\ `Figure 3, alongitndinal section, and

Figure5 is Aau edge `t'iew, and `Figure 6, a top `view of an inside ttn-stickblauk, as molded on one sideby themachine. Figui-e7 is an edge view of` such blank, as molded on its opposite sides, or reducedto the shape for being-split, by a gang of saws; into fan-sticks.

11`igure 8 is ,an edge viewbf van outside fan-stick blank, asmolded on one side by the machine."

' Figure 9, is an edge view of the blank, as molded on its opposite sides: f In some respects lthe machine is siniil'antofa coinmon `plane-surface wood-planing i machine, but it dit'- ifsm for doing what snch planing-machine'cannot per- \orm.,. i. In` the drawingi A denotes the bench or table of the machine, and 15,'a rotary cutter-stock, whose-journals, a a, are arranged lin boxes b b, projecting-upward fl'onrthe top of the table.` `A driving-pulley, c, is xed'tooue of such journals. l w 'i .The cutter-wheel or stock B isa prism, aving on' eaohot 'its sides a groove, cl, extending lengthwise through it, and being dovetailedinV horizontal section for the purpose of receiving the head'of a clamp-screw, e, t'o operate with a nut, f,iu fastening a cutter, g, toI

such side.

` Thereis a spring presser, C, in rear of the cutterstock, and there is also another `such presser, I), in advance of it, they being each provided with pressure- `springs h It. Thesesprings'are blocks of India rubber, encompassing scrcw-rodslwhich depend from the pressers, and have thumb-nuts, i @applied to them, for

the pressers.

'lhe advance presser has two plates or bearers, 7s k, `projecting fremit, and held to it by'means of screws and n uts, so arranged as to enable each of such bearers to beadjusted nearer to or further from thebotboard, and aid in holding the board downwhile passi ing under and from the cutters.

l Figure `4, a transverse,sectionrotsuch machine.

fers therefrom in others, it bein gprovided with Inechanthe purpose of regulating the drai't of the springs on torn of the presser, and tipped more orl `less into an `angle therewith, as occasion may require. `V lhe Lpurposeof these bearers isfto rest the dressedpart-of a At a proper distance iu rear of the cutter-cylinder or stoelcis a horizontal shaft, E, whose journals are supported in afralne, F, pivoted tothe table as shownA at Zl. This frame, atv its front part, is providedwith hangers or rods, m m,'wlich hook upon studs projecting from the frame. A ttheir lower ends these vhangers have screwsto receive nuts n n, which screw againstIndia-rubber or other proper springs, o o, en@- compassing the hangers and resting against the lower surface of ears p, extended from the table.

The shaft Eis provided with one'ortwo feed-wheels,

q q,"see `Figure 10, which is a transverse section of the machine, it beingy taken through the shaft E.

Underneath the feed-wheels are tw'lnbed-wheels, F G; `Each bed-wheel hasits journals supported in a box or frame, lr or s, which is also arranged within a box or supporter, t, let into the table-topi Fignrell, is a top view, and f `Figure 12, a. side elevation of the larger bedwheel box and its supporter, with the bed-wheel arranged in thebox. 'Y -1 Figure 13 isy a longitudinal section, and j l Figure 14, a top view of' the smaller bed-wheel, its box, auddthe supporter thereof.

`Inthese latter figures the box is shown as held to the supporter by a clamp-screw, u, and provided with au adjusting-screw, rv. The screw 'fv s crews down through the box and against the supporter, and serves to enable the .box tobe raised more orless on the sup- The other wheel-box4` has one screw, w, for connecting-it. with its supporters; and, besides .sncli, it ,has three :adjusting-screws, 155x, and y, which screw through the box and against thefsupporter. These adjusting-screws are so arranged as to enable a person, by means of them, not only toraise'the box, but

to tip it more or less, lthe tipping of it being to incline the axis of the bell-wheel more or less, as occasion may require.

' `1t will also be seen that the shaft of the larger bedwheel projects-more from one end of the wheel than from theothenaudthat the length of the opening of the boxin which the bed-wheel rests is as long as the shaft is between. Such isfor the purpose of enabling the bed-wheel to beset in `two different positions or distances from the vother bed-wheel. By raising the lar-ger bed-wheel out 4ot'l its -bearings,.and turning it around horizontally one hundredaud. eighty degrees',i and replaeurg itin t-he bearing,}the wheel .will be brought nearer to the other.

The above-described adjustmentsof .the bed-wheels become necessary, to adapt the machine to the formationof fan-stick blanks varyingin size o r length.

'A cap-plate, z, is arranged overthe box'of each of the bed-wheels, and withiits uppersnrface even with that of the table.

Furthermore, the shaft E has a gear, a', xed on one end of it, such gear being made to engage with a pinion, 1)'ixed on a driving-shaft, c'.

On the shaft c is adriving-pulley orwheel, d', the shaft being provided with a clntch, e, to be'operated by a lever, f'. The said clutch' serves to engage or diseugage the shaft and pulley-wheel, as occasion may require, in order to cause such shaft to be put iu rev olution by the wheel, or be at rest, while the wheel may be in movement. Y

'Underneath the shaft E, and held to the table-top by screws g', arc-twov longitudinal bars or guides, H H', having transverse slots going through them, for the reception of the screws g', which are screwed into the table. These guides are adjustable laterally of the tablefand are to guide the piece of board rto the cutters of the cutting-wheel.

There is also 'a gauge, I, extending, from the frame F, at 'or near its middle, in mannerand formed as represented. This gauge serves to bring the part h' (see figs. 5 and 6) of the dressed blank into proper position on the table preparatory to the adjustment ot' the guides H H.

' Other adjustable guides, K K', are arranged on the table, and in advance of the guides H H'., The said guides K K extend along underneath the pressers C D and the cutter-cylinder stock B. The said guides K K are held to the table by screws going through slots arranged transversely in the guides; and, fur thermore, there. are, to one of such guides, certain screws, t' i', one for forcing the guide inward toward its fellow, and the springs are to cause the guide to fit closely to a piece of board, and keep-it in contact with the fellow-guide while such piece of board may be slgbjco'ted tothe action of the cutters of the cutter-. st-oc f In advance of cach'of the bedfwheels, and extend ing underneath the cutter-stock and presscrs,vthere is also a bed-guide, thc same being as shown atL and M. l l

The smaller of these bed-guides is movable vertitically within the table, and is provided with adjusting-screws m' m' n',by which its vertical position, with respect tothe upper surface of the table, may be regulated.' l

The other bed-guide M, arranged in a slot, N, wider than the guide, is held down by screws o o, which go through slots extending transversely of the machine.,

Clamp-nuts 11 p on such screws serve to Aconfine the guide M in position. Thus it will be seen that the guide-M isadjustable laterally of the bench, and caa piece of board to the shape as shown in section at fr h' s t' u', iniig. 5, and the bedlwheels and bedn guides having been disposed so as to be even with the top surface of the table, and the edge gauges also having been properly adjusted, the piece of board to be dressed should be placed between the' rear edge gauges and advanced up to the feed-wheels q q. These feed-wheels, as the' pieces of board. are. successively brought up, will advance them, or each of them, to-

. ward the outterfstoclr, which, as 4they in succession pass underneath it, will dress them to the required shape on theirfupper surfaces.

After being thus dressed, any desirable number of such pieces of board, the bed-wheels and bed-guides should be properly adjusted to support cach board at its bottom s t, and on the part lr h', while .the piece may be again submitted 'tothe action of the machine, which should follow in order to reduce the board on its opposite side in proper correspondence with the first reduction, vthe two reductions bringing the boand into a shape whose transverse section is represented in fig. 7 or in tig. 9, as the case may require. In the above-described machine, I claim, as my invention, the following: 1. The combination of the adjustable bedfwhecls F Gr, bed-guides `L M; and vedge guides H H'YK K', with the cutter-stock B, and one Vor more feed-wheels, q, the pressers C D, and the table or bench A, the whole being arrangec'l substantially inv manner, and so as to operate together, as and for the purpose as explained. 2. The combination of the gauge I with thevframe F, the feed and bed-wheels, thc cutter-stock, the pressers, and the edge and bed-guides, arranged with the table or bench, and to operate together, as set forth.

3. The combination of the adjustable bearers k k with the front spring presser, when combined with the rear presser, the cutter-stock, the feed and bedwlieels, and guides, as set forth.
