SPEGIFICATON forming part of Letters Patent No. 579,129, dated March 23, 1897.
Application filed August 17, 1896. Serial No. 602,939. (No model.)
F all whom, it may concern:
Be it known that I, ARTHUR CARRIER, a citi- Zen of Canada, and a subject of the Queen of Great Britain, residing at Bay City, in the county of Bay and State of Michigan, have invented a new and useful Improvement in Saw-Swages, of which the following is a specification, reference being had to the accompa- :nying drawings, and to the figures of referro ence marked thereon, which form a part of this specification. 4
My invention relates to improvements in saw-swages in which an oscillating die provided with a cam-face in conjunction with a stationary anvil-die operates to produce the swaging or spreading of the material in the point of the saw-tooth.
One of the objects of my invention is to provide a machine whereby the material for 2o widening the point of the tooth is removed from the back or rear side of the tooth, whereby the front or cutting side of the tooth is left true and straight and free from the impressions of the die. v
Another object of the invention is to arrange a swaging and anvil die so that when the impression of the swaging-die is made upon the back or rear side of the tooth the material of the point is spreadlaterally to a 3o greater distance on the front side ofthe tooth which rests upon the anvil-die than at the rear side or the portion receiving the impression of the swaging-die, whereby a better clearance for the saw is obtained and smoother lumber is cut.
Another object is to so arrange the stop for the swaging-lever that it may be easily7 displaced and allow the die to be rolled over to catch a short or blunt tooth and draw the 4o saine forward and to a thin point.
I attain these objects by means of the mechanism and contrivances illustrated in the accompanying drawings, in which- Figure l represents a vertical longitudinal central section of asaw-swage containing my improvements. Fig. 2 is a transverse section ofthe same, taken at the broken line a a. Fig. 3 is a transverse section of the same, taken at the broken line b l). Fig. l is an end view of 5o Fig. l, looking to the left and partly sectional. Fig. 5 shows a transverse section of the swaging-die and the side of the anvil-die detached and in position for swagingasaw-tooth. Fig.
6 is a section of the same, taken at the broken line d CZ. Fig. 7 is atop view ot' the gage por- 55 tion detached from the block. Fig. S is a top or plan view of the stop-arm for the lever and detached. Fig` 9 shows the front or cutting side of a saw-tooth swaged by my machine. Fig. l0 is a rear view of the same. Fig. il 6o is a view of the lateral side of the same.
The same iigures of reference are used to designate the same parts throughout the several views in the drawings.
l represents a swage-block, preferably of rectangular form, and this block is provided on its under side with a slot 2, cut longitudi nally into the block for receiving the
sawteeth 3. Into the rear side of the block is arranged an opening i, reaching into the slot 7o 2, having its outer portion threaded, and 5 is an anvil-die passed into the opening 4 and is arranged 0n the upper side of its inner end portion with a diagonal die-face 6, having its middle portion slightly raised or rounded over 7 5 for a purpose which will be presently eX- plained. p
7 is a screw fitted into the threaded outer portion of the
opening 4, and the inner end of'this screw is arranged to bear against the 8o outer end of the die 5 to retain the die in position against the strain of swaging the tooth and for adjusting the anvil-die to and from the tooth, as desired.
At a point coincident with the central por- 8 5 tion of the dieface 6 the swagewbloclr is provided with a transverse opening 8, reaching across the anvil-die to a suitable distance, and into this opening is Iitted a cylindrical swaging-
die 9, with its outer end extending 9o beyond the side of the block and provided with a lever l0 for oscillating the die, and the inner portion of the die, which crosses the anvihdie face, is provided with a die-facc ll, which is arranged by cutting away the die and forming a Irecess l2 on this portion of the dic, which is coincident with the anvil-die face, so that the faces of the anvil and swaging dies will oppose each other with a 'space between for the insertion of the point of the roo saw-tooth, and the anvil-die then resting in the recess l2 serves to retain the swaging-die in its proper relative position and prevents its removal from the block.
The front and rear edges of the die-
face 11 are rounded over, and the central portion of the face is provided with a longitudinal recess 13, which when the die is in position for swagin g receives the point of the tooth against its rear side and forms a stop or therefor.
bolt 14 is passed into the upper side of the block and is arranged with its en d resting against the outer end of the an vil-die for holding the same firmly in position.
On the front portion of the block and on the side of the slot 2 a threaded clamping-
bolt 15 is passed into a threaded opening, and the inner end of this bolt extends into the slot 2 and rests against one side of the saw-tooth and is rendered stationary after being adjusted by a set-bolt 16, and through the portion on the opposite side of the slot 2 is passed a threaded clamping- bolt 17, with its outer end provided with a lever 18 and with its inner end extending into the slot and impinging against the saw-tooth directly opposite the bolt 15, so that the tooth is then firmly clamped between the bolts by turning the lever 18 to screw the bolt inwardly, or the tooth may be loosened by moving the lever in the opposite direction.
Upon the upper side of the block is secured by
bolts 14 and 19 an arm 20, which extends to some distance beyond the side of the block and reaches over the saw, and the outer end of this arm is provided with a vertical opening 21, into which is passed a vertical standard 22, held in position and rendered adjustable for different saws by a set- bolt 23, and the lower end of this arm is pivotally connected to the middle portion of the upper side of a gage- piece 24, the under side of the gagepiece resting upon the points of two or three teeth of the saw, while portions 25 of the gage project downward over the lateral sides of the teeth to prevent a lateral displacement of the gage.
vertical standard 22 being capable of adjustment allows the block to be tilted to bring the anvil-die face to conform to the line of the front edge of saw-teeth having different inclination on different saws, and the lower end being pivoted to the gage-piece allows the swage-bloclc to be slightly raised over the point of one tooth and adjusted upon another without lifting the gage-piece from the saw, the gage-piece sliding over the points of the teeth, which allows the operation of shifting the block from one tooth to another to be rapidly done without paying particular attention to the gage.
Upon the upper side of the swage-block, and preferably resting upon the upper side of the
arm 20, is secured the arm-piece 2G, and this arm-piece is provided with the 1ongitudinal slots 27, through which are passed the bolts 14 and 19, the slots allowing an endwise adjustment of Ixthe arm-piece, and at its rear end the arm-piece is provided with a laterally-projectingarm- section 23, to the outer end of which is pivotally connected at 29 an extension- section 30, which reaches beyond the track of the lever 10, and a spring 31 is arranged to bear upwardly against the inner portion of the pivoted end of this arm and retain it either in an extended position, as shown in Fig. 3, for stopping the backward throw of the lever or in an upturned position, as shown in Fig. 4, for allowing the lever to be moved beyond the arm to widen the space between the die-faces, so as to permita tooth which has a blunt point or sharper inclines than usual to be acted upon by the dies and drawn forward to a cutting-point. Of course it will be understood that the saw often cuts into a stone or gravel which has in some manner become embedded into the bark or wood of the log, and the saw coming in contact with these obstructions generally loses the points of three or four teeth, and these teeth are then fitted up with points in the best manner possible, and the saw is then used until the full teeth have been worn down to coincide with the points of the imperfect teethand by the use of my device these short and imperfect teeth can be drawn forward and fitted with fair cutting-points, as when the section 30 is in an extended position the lever 10 rests against it, and this position of the lever leaves the proper space between the anvil and swagin g die faces for the insertion of the saw-tooth having the usual form and contour, the tooth being placed with its point resting against the rear side of the depression 13, where it is firmly held by the clamping- 15 and 17. Then the lever l0 is moved forward, and the swaging-die is thereby oscillated, so that the front rounded portion of the die-face is pressed into the top of the tooth, moving the metal slightly forward and laterally and also toward the anvil-die, which being provided with a transversely-rounded surface causes the material on the front portion of the tooth to move laterally in advance of the portion in contact with the swaging-die face, so that the width of the swaged point next to the anvil-die or the cutting side of the point will be wider than the rear portion thereof, which is in contact with the swaging-die, which, it will be noticed, is a very great advantage, as the front or cutting edge of the tooth is thereby arranged to provide a proper clearance for the sides of the swaging, so that smooth and perfect lumber is produced,v and the speed of the feed can be increased without clogging or heating the saw, while for swaging the short and imperfect teeth before mentioned the arm- bolts section 30 is thrown back, as shown in Fig. 4, and then the lever is moved beyond the arm for opening the space between the die-faces to allow the blunt tooth to be inserted, and the anvil-die then impinging well back upon the tooth operates to draw the material forward and form the point as near as possible to its former shape and contour.
Of course I do not claim to be the inventor of an oscillating die Working upon the front or cutting side of the tooth, nor of the devices for clamping the sWage-block upon the saw, as these devices are in common use, but by the use of my improvements much better and more expeditious Work can be executed and a large saving made in the lumber produced.
Having described my improvement, What I claim as my invention is- 1. The combination in a saiv-swage of the sWage-block provided with a central longitudinal slot for receiving the saw, an anvildie passed into said block from its rear side and provided on the upper side of its inner end with an inclined die-face having a transversely-rounded surface, a cylindrical swagingdie passed into said block from one side and having its inner end portion extending across said anvil-die face, and provided on the portion opposing said anvildie With a transverse recess for receiving the anvil-die and having on the bottom of said recess a dieface provided with a rounded front edge and with a longitudinal depression in its middle portion, a lever for oscillating the die, and the bolts for clamping the block upon the saw-tooth, substantially as set forth.
2. In a saW-sWage the combination of the swage-block carrying an anvil-die and a cylindrical sWaging-die passed from one side into said block and provided on its outer end with a lever for oscillating the die, With an
armpiece 26, provided with longitudinal slots 27, and adjustably secured to the block by bolts 14, and 19, passed through said slots and provided on its side With an arm-section 2S, extending laterally toward said lever, an outer section 30, with its inner end pivotally connected to the outer end of said arm- section 28, and With its outer portion extending be yond the line of movement of said lever, and a spring for holding said outer armsection in an extended or in an upturned position substantially as and for the purpose set forth.
In Witness whereof I hereunto affix my signature inthe presence of tivo Witnesses.
