ALLI-Nv HAGKETT, OF PITTSFIELD, MAINE.

Letters Patent No. 82,518, dated September 29, 1868.

IMPROVEMENT IN SAW-MILLS. Y

TO ALI] WHOM IT MAY CONCERN:

Be it known that I,AALLIN HAGKETT, of Pittsfield, in the county' of Somerset, and Stateof Maine, have invented a. newand useful Improvements in Saw-Mills; and I do hereby declare t-hat the following is a. full,

c lear, and exact description thereof, which will enable those skilled in the art to make and use the same, Y v

reference being had to the accompanying drawings, forming part of this specification, in which- Figure is a side view of my improvements as attached to the saw-bed and carriage.

Figure 2 is a top view of the same.

Similar letters of reference indicate corresponding parts..

The object'of this invention is to provide means for gauging the planks to be sawn, in a simple and accurate manner, by means of an improved head-blockY and gauge, which latter serves also as a device to prevent the last planks of the log from springing. 'It consists oi' the mechanism set forth in the following:

A is the bed or frame of the saw E; B -is the carriage, on which the head-block H, bearing mechanism for setting up the log to the gauge, rests.A

The carriage B slides in the guides C C, aiixed to the frame D, on which latter the saw-frame A is also aiixed. v Y l The head-block His formed with a. cavity, Q, within which are horizontal parallel slots, formed on the inner faces of the head-block, for the tongue-projections of the sliding plate O.

A portion of'the head-block is broken away to exhibit the said slots, and the tongue-projection z' working therein. l

M is a standard arising from the sliding block O, and forming part of the same.

L is another standard, arising from the sliding blockO, and against which the log rests, as shown by the red 'color representing the log.

The sliding block also bears a vratchet-rack, c, which projects from the sliding block over and upon thev upper face of one of the sides of the head-block, as shown.

This'rack is for the purpose of receiving the end of the pawl ,lpivoted to the hand-lever K, and soarranged that the pawl will catch in. the teeth of the rack,and aotuate the sliding block forward, when the lever K is vibrated. l Y y The leverl is pivoted to the head-block in .any-manner suitable for that purpose, as shown.

As the sliding block is moved forward, the standardL thereof beurs against the log, and moves it towards the gauge-roller P, bringing the log in contact with the said roller.

Another pawl, a, is pivoted to the leverhandle, and engages with a ratchet-rack, J, projecting horizontally from an upright, I, 'ailixedto the bevel-block.

This latter pawl and rack servesl to hold the standard L rmly against the log, as shown.

The upright, M, bears a pointer, L, which denotes, on an indicator-wheel, d, -the number of plank which have been sawn from the log, .or it may be graduated to indicate the set, so called, for any thickness of plank.

This wheel rl has a' toothed parte, which engages with the rack-pins, or their equivalent,I whereby the indicator or set-wheel d is rotated when the slide-block is moved forward.

The shaft of the wheel CZ has a single bearing in the standard M, and travels with it as the slide-block is moved.

The gauge-roller P revolves on the upright stud on the plate 3,' which latter isjointed, asl shown at m, to the plate R, both plates being arranged to slide in a recess in the part U, aiixed on the saw-bed, as shown.

The plates are actuatedl by a feed-screw, o, turned by a hand-wheel, n.

lhe face ofthe part U is graduated, so that the rear end of the plate R can be set to any mark, to adjust the thickness of each plank.

The joint of m is for the-purpose of, enabling the plate S to be swung off at right angles, when the .log is Abeing slabbed.

In operation, the end of 'the plate R is set at the proper mark on. the partAU, and the log set up by the head-block mechanism, to bear lightly against'the roller P, so that the plank may be held from springing.

T is a. guide-plate, ailixed on the. plate R, and formed with a shoulder, to hold the plate R in proper contact with the part U. v

In setting off the plank, the wheel d, or the gauge U R S P, may be used separately er in conjunction with each other, as desired.

The feed-screw o works in a. hollow thread in the' plate R,

boss u.

I claim as new, and desire to secure by Letters Patent- 1. The gauge-device, constructed, as described, of the plate S, bearing the roller P, and jointed,v at m, to the plate R, which is operated in a recess of the graduated part U, by means of the feed-Screw o and handwheel n, all arranged and operating as described for the purpose specied.

2. The described arrangement ofthe setting-up mechanism upon the head-block,l consisting of the sliding block o, rack e, standards Ii M, pointer h, indicator-wheel d, having the toothed part e, the pins e', lever 1K, bearing the pawls a 6, the standard I, and slotted notched bar J, all operating as described for the. purpose specified.

. ALLIN lHCKEIT.
