Description
tniib Staten lWAIJJER LAFAYETTE (lh ST. LOUIS, MISSOURI.
Letters Patent No. 110,966, dated January 17, 1871.
IMPRovEMENT iN lsaws.
The Schedule referred to in these Letters Patent and making part of the same.
panying drawing and to the letters of referenecma-rked` thereon.
This invention relates to saws in which false teethA are inserted and secured to the plate; and
Ihc nature thereof consists in forming the teeth with a rectangular b ase, and having end lugs, the in-. ner inclines whereof are such as to widen the mortises formed between the lugs andthe buse at the lower ends. rIhus the'lugs act as a wedge t0 force the material of the saw-plate toward the buse. In this ,wise there is a connteracting force achieved to the tendency to split the saw-plate at the lower corners at the base ot' the tooth. t
To enable those skilled in the art to make and use my'saidvinvention,- I will now more fully describe the same, referring to the accompanying Figure l as a section of a circular saw with tooth inserted; to
Figure 2 as a perspective view with tooth detached.
A represents the saw-plate constructed of the material usual.
I3 represents my improved toothybaving the end lugs 7) and rectangular base:A C formed as indicated in the figures lhe outer side edges of the lugs b and hase (l are recessed with a V-groove, while the edges of the plate A, where said V-shaped edges engage, are properl y beveled to it said V-grooves in manner usual.
-In order to prevent any liability ot the plate A from splitting or otherwise breaking at the angleedges a, and to equalize the pressure-force upon the pla-te, I construct the inner faces or edges ofthe ings b, having a slight inclination, b', as clearly shown in fig. 2. e The teeth thus formed and inserted in the plate A (first properly xnortised) are secured in position by a proper rivet, c, one-halt` which is in the tooth and the other half in the saw-plate.
It will be observed that this method of' construction prevents all manner of expansion, and strengthens thoseparts of the saw-plate most liable to. rupture,.and that the greater the resist-ance to cxpansion the tighter the teeth become.
Having thns'fnlly described luy said invention,
The. tooth, having end lugs b, inclinesv b',` and rectangular base C, in combination with a corresponding recessed saw-plate A, substautiallyas and for the purpose set forth.
In testimony of said invention I have hereunto set my hand in presence ot- WALTER L. GAGE.
