DAMON A. CHURCH, OF FRIENDSHIP, NENV YORK.
MANNER OF ARRANGINC-r AND OPERATING DOGS OF SAWIVIILLS.
To all whom-15 may concern.'
Be it known that I, DAMON A. CHURCH, of Friendship, in the county of Allegany and State of New York, have invented certain improvements in the manner of arranging and operating the dogs of sawmills as constructed by Hezekiah Thurber and described by him in the specification of Letters Patent granted to him and bearing date May 30, 1838; and I do hereby declare that the following is a full and exact description of my said improvement thereon.
In the accompanying drawing A, A, Figure l, is a view of a saw mill carriage, with the head block B, and the tail block C, placed upon it. Fig. 2, is a view from the opposite end of the machine, C being the tail block.
In the head and tail blocks, the slides a, a, upon which the dogs are fixed, and the dogs also, are, in their general constructionthe same with those used byV Thurber.
My rst improvement is in the manner of shifting and setting the log on the head block.- In Thurbers machine the notched piece Z9, attached to the slide a, served to shift or set the log by receiving the front of a crow-bar, there being several pegs, orpins placed along in front of the notches of the slide to serve as fulcra for the crow-bar. In the arrangement of the apparatus for shifting the log, adopted by me, it is shifted and set by means of a treadle, upon which the operator places his foot, and by this means draws the log toward him, without it being necessary to use a crow-bar, or any similar instrument; and this I effect in the following manner: c, 0, Fig. l, is a bar of iron, having a projecting piece cl, at its end, which piece lits into either of the notches on the piece b, of the slide. A chain e, attached to the opposite end of c, is fastened to and may be made to wind around, the periphery of a wheel f; which revolves on the vface of the head block.
D, is a treadle of which the pin upon which f revolves, is the fulcrum. The edge of the wheel f, toward the treadle, is cut with teeth so as to constitute a ratchet wheel, into which a tooth on the inner end g, of the treadle engages. The treadle is borne up against the ratchet by a spiral spring L, surrounding its fulcrum pin, and thus allowing the tooth on the lever to recede, or escape, from the ratchet teeth. Aspring z' bears against the under side of the treadle,
and raises it to itsplace, when the pressure of the foot is taken 0H.
E, is a vertical lever by moving which the screw y', that serves to loosen, or tighten the slide a', may be operated. The lever E, works upon a fulcrum pin passing through it and into'the head block, near its lower end, and from this end the jointed rod f: extends to the arm Z, of the screw; by moving the lever in one'or the other direction, the screw may be acted upon by the tender of the mill while standing by the treadle D. The tightening screws j and m are similar to those employed by Thurber for fastening his slides, but by him they are both used by hand. What I claim in this part of the structure, as new, is the manner of connecting the bar c, with the notches, on th'e slide a', and ofl operating said slide,
by means of the ratchet wheel f, and the treadle D, with their appendages as described, so as to move the slide a, and set the log; the whole arrangement and combi-k nation being made as set forth. I also claim,
vin combination therewith, the employment of the lever E, with its connecting rod, for operating the tightening sere/w On the tail block @,the dog in, has a face piece 0, which serves to gage the thickness of the stuff in the same manner as in Thurberfs machine, the slide a2 upon which thev dog n 'is sustained'bei-ngproperly adjusted;
be moved out of the-way by hand in order to remove the board; this part I have rendered self acting, and the manner in which I effect this will be best seen in Fig. 2. In this figure p is a shaft which turns in the bearings g and r, and has on its inner end a cranked piece s, which is attached to the free piece 0, of the dog n, by a jointed rod z5. rIhe piece 0, is shown in the position in which it sustains the board after it has been cut. On the outer end of the shaft is a jointed pendent u, by which the shaft 20, is to be lturned when the face piece o, is to be moved out of the way of the board. As the carriage A, A advances, the piece u, comes into contact with a piece of timber 'a which is fastened to the oor of the mill, alongside of the carriage and as the piece u swivels around on the end of p when the carriage is advancing, it is lifted and passes over the top of the piece e, there not being any action on the shaft p; but as the carriage is backed the piece u comes into contact with the end but inThurbers machine the dog n had to fu', of the piece o, over which it passes, but
in so doing it rocks,` or carries around, the shaft p, and draws the dog a, over, so asto remove the face piece o, out of the way of the board, allowing it to fall over and be removed.` ToI insure its falling over, and to remove it out of the way of the dog a, when it returns to the situation shown in Fig.` l, I use a spring piece w, which is attached to a rod, or shaft that passes through the tail block, andhas on its other endfm Fig. 2, the lever y` which is acted ufpon and made to vibrate by the rocking of the shaft y), its lower end being raised when the `crank piece s, 1s made to draw upon thc `dog a; the spring b", bears on the upper end ofthis lever, and again raises that end when the action ofthe shaft 79 upon it has ceased.
"In Fig. 3, Z9` is the inner end of the" shaft `@and s` the `crank piece attached to it; a
pin c on the lower end `of the crank piece,
`passes `into an opening made tof receive itin the lower end of the lever y, as shown at cZ,
andas: theJcrankpiece is thrown out, the sliafti ofjth'e lever is moved around, and withit the spring piece w, at its opposite end. The board `which has been separated andi fallsover intothe top nof this spring piece, is pushed over by, it, :away from the log, and clear of the point ef, of the dog, which might otherwise fall `upon and in jureit.` l i,
`the log is. shifted upon the head block `by `rneansofthe treadle D, the dogf? upon `the slide afmay` stand in the position shown in the drawingwthe. slide` as, being i. fastened `bythe.screw m, in the proper positzionto` :gage the thickness of the stuff to` be `cnt, whichzlis done by :bringing "it against thesdezg"` of thedogf` nforderA to allow the `board to fall over, :the dogfff must be drawn back out` of its Way, its` operation being similari` to that aft-he faceA piece 0;, on the degat, on the `tail lclfockyto` effect this; Itatdog f back `at the proper time. `shows the manner in which I arrange this tach a joint rod t, to the dog f', and to a rock shaft, or lever l',the lower end of which lever reaches nearly down to the floor of the mill so as `to be brought into contact with a tripping piece attached to said floor, and operating on the rock` shaft so as to draw the part of the apparatus; 7c is the tripping piece placed in a mortise in the floor of the l null, and haring a vweight Z attached to 1t;
asthe lower end of the rock shaft "comes into contact with the tripping piece, it will, in passing in one direction, draw the dog f' back suiii'ciently far to `relieve the` board, and in the other restore it to its former position; when drawn back, the board will be left free to fall over.` By the arrangement for `allowing` or causing the board to fall over, niuch labor issaved in theremoval of the stuff as it is sawed.
What I claim as new in the last described parts of my apparatus, isi i l. The manner 1n which I'have arranged and combined the parts on the tail block, for` withdrawing the dog "a, after a board "or i plank has been cut, so as to allow, and cause, it to fall over; that is to say, I claim the apparatusconsisting of the shaft p, and its a-p` pendages, by which it is made to draw the dog a back, andto act upon the spring piece fw, the 'said parts being` arranged subst-antially in the :manner set forth.
2. `I also claim themanner of withdraw` jing and replacing thedog f, on the head block, bymeans of thejointed rod, rock shaft,- and tripping piece, arranged, conibined, and operating, substantially as set.
forth. Y
