To al'l whom it may concern.-
Be it known that I, Josern S. Dmmmx,
' a citizen of the United States residing at NorwaIln-in -the county of l airfield and State of Connecticut, have invented certain new and useful Improvements in Saw- Clamps; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in. the art to which it appcrq taina to make and use the same.
compass, and which will be adapted to clamp and securely hold equally firm saw blades of varying thicknesses, and by which the filin of saw blades will be rendered a practica ly noiseless operation. I
' With these objects in view my'invention consists in certain features of construction and combinations of parts which will be hereinafter described and pointed out in the claims.
In the accompanying drawings, Figure 1 is a View in perspective of my improvement. Fig. 2 is a plan view. Fig. 3 is a view in rear elevation. Fig. 4 is a transverse section taken through one of the end arches of the device, andFig. 5 is a transverse section on line 00- of Fig. 2. v
-1 represents the supporting frame of the device which is made of a T steel barto the web of which is riveted the depending ends of an outwardly projecting bracket 3. To the web 2 midway of the bracket, is pivoted the upper'end of the folding standard 4 of a clamping jaw, the standard being made of a'steel channel bar.
5 ,is a. clamping screw which passes through and engages the screw threaded outwardly projecting end of the standard 41;. The upper end of clamp screw 5 is provided with an enlarged flat head 6, while its lower end is provided with a handle 7 which is mounted to slide in a hole 8 formed in the ower end of the clamp screw. The bracket and clamping screw enable the device to be detachably secured to the edge of a bench, table or other support. v 1
The upper flange 9 of the main frame 1 is cut away at its opposite ends for the recepspccification of Letters Patent. Application filed December a, 1911.

tion and attachment of the arch bars 9, which are made of channeled steel and "are. secured in place by screwslo or they may? be fastened to the main frame in any other tie sired manner. Upon theupp'er surface of the flange 9 is secured a steel clamping plate 1.1 by means of screws 12; The outer edge-12 of clamping plate 11 is made to flare upwardly to form a wed e shapedspace 13 between plate 11 and within which is pad 14 which is rubber projects angetl preferably made 0 and the outer surface of which slightly beyond the outer ,edges of and clamping plate 11.
15 represents a opposite endsoi which are screw threaded for the engagement therewith of screws 16,
.flanlge 9 firmly clamped a "e ding which pass through holes in the arch barsf Upon the outer end of each screw is placeda spiral spring 17, whicb sprin'gs serve tomove the clamp bar 4c away from the-rubber" padl l.
18 a cam locking bar the opposite ends of which are each provided with a journal 19 which is located at one side of the center of the bar, and is mounted in a bearing formed in-the arch bar. This bar is promeans'of which it is partly rotated. The handle 20 on being moved operates to partly rotate the locking bar and cause it to engage and depress the clamp bar and force it against the saw blade, one .t'ace of which rests against the rubber pad as imlicatcd in dotted lines in Fi 5. The clamp bar 15 is made of suilicient width to insure ample strength and rigidity and an extended clamping blade.
The frame work being formed of T steel bar and of steel channel bars is of extremely light weight, but is strong and rigid and capable of withstanding the strains imposed upon it without liability of being bent or flexed.
Having full y described my invention what I claim as new and desire to secure by Letters-Patent, is
1. In a saw clamp, a main frame formed of a steel bar having a horizontal flange and a vertical web, the flange bein cut away at its ends on one side of the we and steelweb at the cut .tway portions of the flange,- substantially as set forth;
surface on. the saw v the vertical I 70 yielding clamp bar the rubber strip secured vto the main frame ofclamp bar meuni eci on I guides supported; by the arch bars, ami a: mm ieci'c ingbar mounted to engagethe rear face the clamp bar; substantially as set feiihi 4, In av saw clamp, the combination 0;; z: supporting ffrzmie or bar, arched bars 59- a 'yieiaiing i. curedihereio, near its ends, clamping eiaae havirig en. outwamily fiaringedge and secureci to the upper surface 01''. the supporting frame or bar, a yieldihg strip secured between said supporting frame end plate, and means carried, by @he {see emis of the areiiee em {02? clamping a saw against the yieiiiine" s rip.
5, in saw vei'an'np, the comhinetou with mmmwmhw.
the main flfiifi prositieiiwiih a jrieiiiing strip exiiemiing; its entire length and' having arch bars at its ends, of a clamp bar supported by guides mounted in the arch bars, springs for retracting the clamp bar, and a cam lacking bar adapted] to engage the ciainpbar througheut its iengiii.
6. The combination of a main frame ,pro-
videci with a horizontal flange, a rubber strip clamped to'saici flange anci progecting beyomi' its inner. edge, arched bars secured in main tei', yielding ciempiiig bar carried by said bars zdjaeenb the We ends of the ifitil.,"il said clamping bar being iocsiied opposite the rubber strip, and means for forcing the clamp teward the rubber strip.
In testimeny whereof, I have signed this specification in the'presence of two subscribing witnesses.
S, DIKEMAN.
