JOS. J. PARKER, OF PLYMOUTH, OHIO.
SELF-SETTING HEAD AND TAIL BLOCK OF SAV/'MILLS T0 all wit-om t may concern Be it known that I, Josnrrr J. PARKER, of Plymouth, in the county of Washington and State of Ohio, have invented a new and useful Improvement in Self-Setting Head and Tail Blocks for Sawmills, which is described as follows, reference being had to the annexed drawings of the same, making a part of this speciiication.
Figure 1 is a top view of the head and tail blocks, together with the carriage; showing also the self acting holdfast. Fig. 2 is a vertical longitudinalisection through the center of the self settingapparatus of the tailblock,
drawn at the dotted line ai, of Fig. 1Q
Fig. 3 is a vertical transverse section of the same drawn at the dotted linelO, 10, ot Fig.
. 1. Fig. 4. is a vertical longitudinal section through the self setting apparatus of the head block drawn at the dotted line 8, S of Fig. 1. Fig. 5 is avertical transverse section of the same, drawn at the dotted line 9, 9, of
Fig. 1. Fig. 6 is a view of the underside of the head and tail blocks and carriage turned bottom upward. Fig. 7 is a plan or top view of the floor of thesaw mill, upon which are seen the flat sills or streainers, with the `inclined wedges, &c.,"by` which the setting apparatus are set in vmotion by coming in contact with the same, as the carriage moves. Fig. 8 represents a side and top view of the slide of the tail block. Fig. 9 shows a front view of the hold fast. Fig. 10 is another modification of the tail block showing an inverted V shaped plate for straddling the slide C to prevent slipping and to do away with the notched plates. y
A in Figs. 1 and 3 represents the permanent part of the tail block, made without the usual rabbeted bearing, the latter being made movable and called the slide block.7 B, a
`horizontal bearer fastened to the carriage in front of the permanent tailblock leaving a suiiicientspace between the bearer and block to admit of the free motion of the slide D.
C represents the slide for raising against the slideblock (with the log thereon) and moving it toward the saw, by runnin in contact with the inclined wedge 7 of Fig. l as hereafer described. Said slide has three sets of saw like teeth placed crosswise for holding. It consists of a rectangular bar of timber, flat on the upper side which comes in contact with the slide block, and having formed on the underside an oblique inclined Specification of Letters Patent No. 3,629, dated June 13, 1844.
shoulder S as represented in Fig. 2, against which shoulder= the inclined and beveled edge oft' the inclined wedge W comes in contact for sliding it toward the saw, and having a notch or mortise in the front side ot it near the end into which is inserted the end of a spring G fastened to the top oit the carriage, which throws back the said slide; after having performed its lateral movement and set over the slideblock with the log'thereon. As the carriage advances toward the saw while cutting the log, the spring G presses the oblique inclined shoulder of the slide against the inclined beveled edge of the inclined wedge WV, when by the time the said slide passes said inclined wedge the slide is brought to its former position ready for a new or another set. On the underside of the permanent tail block is a sliding gage g for determining the thickness of the boards to be sawed, having a wedge shaped end passing under the slide C, against the beveled edge of which slidinggage a shoulder on the underside of the slide strikes, said A slide moving horizontally and liatwise against the underside of the tail block, and between the tail block and cross timber ot the carriage and secured there by means ot a wedge or screw or any convenient manner. By advancing the wedge shaped end of the gage between the carriage timber and shouldertormed on the underside and near the end of said slide, the throw or movement of the slide is diminished, by withdrawing the gage the distance of movement is increased, thereby increasing the thickness of the board.
` D represents in Fig. 2 the slide block rabbeted in the form of a right angle or like a common headblock, made movable. This slideblock is placed upon thebearers B, (b) Fig. 3, and over the slide C, and immediately in front of the permanent tailblock. It is held down securely by the holdtast7 M when its weighted arm or lever O is down, and loosed or liberated when said arm or lever is raised. The end of the log rests upon this rabbeted slide block. Immediately behind the slide C and fastened to the front of the permanent tail block is a short bearer (o) upon which the posterior part of the slide block D rests-'See Fig. 3.
E represents in Figs. l and 7 the flat sill placed on the floor of the mill, and fastened permanently there, upon which the inclined l wedge shaped way is placed. In said sill there are holes -orapertures for receiving dowel pins a, a on the underside of the wedge shaped inclined way `W, as represented in Fig/3, for adjusting said way to the length of the log to be sawed.
1W represents in Fig. l the aforesaid inclined wedge shaped way, havingits upper and inclined edge sloped or beveled, against Vwhich slope .or bevel, the oblique inclined` shoulder S on the underside of the slide C comes 'int contact in running the carriage back which causes a lateral movement ofthe slide On the underside of the way are dowel pins a, a, asshown in Fig. 3 which are received by'corresponding holes or apertures in the flat sill E.
Fl as shown in Fig. 6 is a rectangular shaped bar of timber fastened transversely on .the .underside of the cross timber of the-` carriage, beneath the. tailblock, extending forward under the bearer B andbeing let into said=bearer so as to prevent a lateral movement of said bar F of timber. Said cross bar F'has a groove on its upper surfacecorresponding tothe aperture or space between the. two bearers B l) in which the` slide C moves back and forth, said cross timber or barF passes'along the straight side w m of thebefore described way WV (Fig. l) and prevents-'the carriage from being ..pressed sideways, by the action of the shoulder on the. underside of vtheslide C against the. inclinedfedge of the way WV.
.G as shown inFig. `Il, represents the spring for` holding .the shouldered part c c of the slideC against thel sliding. gage. g. so. that as actingfuponHthe slide, which .produces the.
simultaneous .vertical and lateral movement of' thelslide` C together with the slideblock andvlogv thereon.I i
I .of Fig. 9 represents aneccentric on the` endyoffan axlev J .see Figs. l and 9 *passing*` through4 the vtail block. secured to. the tail block-; vhaving aweighted .lever @,onv the opposite end of said axle, for bearing Vthe.
holdfastrhard .down uponY the sliding: block. forzholdingit fast andsteady, while. the saw y 1s passing' through the log ;--vvithout this eccentric andlever, the .motion of the mill would so agitate the slide block with theA log,
thereonxas-to endanger. the breaking,I of the saw.l
Q1: is aA hinged .block for lifting.. said.-
weighted lever for liberating the holdfast A from the slide block, which trips and turns on' its points, and passes over the wedged shaped way l/V as the carriage advances toward the saw without moving the lever and which on running back the carriage or jigging back;y as fit is termed, assumes a straight vertical line, in passing around the inclined vwedge shaped block, or way, WV, causing the lever to rise, and turn the eccentric, and thus remove the pressure from the slide block.
M in Figsnl, 2, 3, 9 represents the hold fast having on its anterior and superior part a shoulder, which fastens upon the slide block. lVhen the weighted lever orI arm is down, it has also a niortise through its center in which the eccentric is situate and operates.
The operation of the foregoing described tail block is as follows, as the carriage. isl run orjigged black, the hinge block@J sus-j pended from the .lever O, comes in Contact with thev inclined edge of the wedge vshaped way lV which presses or `gives, ita lateralv movement, thereby raising the lever, andtiirns the eccentric, suiiicient to raise the holdfast from the slide block, thereby liberatingit from the pressure of the holdfast,
as the carriage. passes on; theobli'que inclined shoulder s of the slide comes in con: tact with the sloped o-r beveled'edge Vof the wedge shaped waylV, and yby the action ofthereon is effected, making the set complete when theaforesaid shoulder s of the slide arrives atvthe. straight part ofy thewedge shaped way-at which time the hinged block suspended from thelever O passes'over therA wedged shaped way lVand lets the weightedlever fall and fasten the. slide. block. Then .as the carriage moves forward toward the saw, the hinge block trips and turns .on its joint and passes over the way lV. without raisingthe lever.
A2 of Fig.` l vrepresent-s the head block. rabbetedor .made in the usual form.
C2 of Figs. 1, 4,5, 6 represents the slide, which .is placed in front/of .theheadblock It is made in .t-wo'parts and yconnected by ai yoke vP Vor otherwise, so asto'leave a space between them for the saw. to retreat. .into
vthe/*groove in. the. headblock,l the .outer end of each halfof the slide being halved `where i they move -laterally Aback and `fort-h over 'the sides-H, of t-he carriage; the inner ends, neXtfto thesaw are suspended yloytenonsfl. Figs. l and 5 fastened to theunder side of theheadfblock, said tenons, passing through` oblongmortises, made. inV the slide of greater length and depththan^the thickness ofsaidv tenons,` so vas to allow; said. .slide to havea corresponding, vertical and horizontal movement, and moving laterally the log toward the saw to be presently described. VSaid slide is held against the head block by means of shoulders on the afo-resaid tenons. Said slide is drawn back to any required distance for a set, as the carriage is running back by a shoulder formed on the under side of one-half of said slide coming in Contact With a Wedge shaped block fw, Figs. 7 and 8, said block being fastened to the floor of the mill at one end by means of a bo-lt or screw or otherwise, the other end being movable so as to regulate the set, by movin` it to the right or left, and maintaining it in its required position by means of a pin 79 placedin the floor. Said slide after being drawn over the required dis tance as aforesaid is raised by running up inclined planes 7c, 762, one of which is connected with the aforesaid Wedge block lw, which liberates the shoulder of said slide from the Wedge block w. The teeth s, s, beingpressed into the log it is carried over by the action of a spring Y Fig. 6 against a shoulder on said slide. Y
s s of F ig. 4 represents a plate fastenedto the aforesaid slide C2 having its upper edge notched in the form of saw teeth, to prevent the slide from slipping` underthe log While in the act of setting.
Y as shown in Fig. 6, is a metallic spring, made of suflicient strength for throwing or moving the slide laterally with the log thereon.
X4 is an inverted V-shaped iron which straddles the slide and supersedes the use of the notched plates.
I disclaim all invention to the individual parts before described. But
What I do claim as my invention, and desire to secure by Letters Patent isl. The manner herein described and set forth in which I have arranged the movable parts of the tail block and combined them with t-he carriage so that by the oblique inclined shoulder S of the setting slide C, and the spring G, in combination with the sloped or beveled edge of the Wedge shaped Way lV (by which the slide C is raised and made fast against the slide block D) a horizontal lateral and vertical compound action is produced the pressure lof t-he slide block D, iviththe log` thereon, upon the permanent bearers B, b, being diminished, and the lateral movement of the log toward the saw effected in the manner and for the purposes set forth.
2. I also claim the manner of set-ting the end of the log` resting on the head block, by the combination, and arrangement of the divided slide C2 connected by the connecting yoke P and the shoulder on the under side of the slide C2 and spring Y in conjunction with the wedge shaped block w, and inclined planes 7c, /02 for the purposes set forth.
