JAMES MELVIN JONES, OF HAMILTON, ONTARIO, CANADA, ASSIGNOR TO NYE COMPANY, OF BUFFALO, NEW YORK.

SELF-ADJUSTING SUPPORT FOR CIRCULAR-SAW AND SI-IAPER GUARDS.

To all whom it may concern:

Be it known that I, JAMES MELVIN JONES, a citizen of the Dominion of Canada, residing at 150 Dundurn street, in the city of Hamilton, in the county of VVentworth, in the Province of Ontario, Dominion of Canada, have invented a certain new and useful SelfAdjusting Support for Circular- Saw and Sha-per Guards, of which the following is a specification.

This invention relates to supports and supporting means for circular saw and shaper guards such as are commonly employed on wood working machines of the nature referred to for protecting the operator from being accidentally injured by the circular saw or rotarycutters. V

The main object of my invention is to provide the support with resilient means whereby the guard automatically adjusts itself to unevennesses in the material being operated upon without interfering with the effectiveness or eificiency of said guard.

A further object of the invention is to provide an easy adjusting means whereby the protective element or guard can be elevated and thrown out of the way of the operator when changing the cutting tool or doing any special work on the operating table when the said tool is not in use.

These objects are attained by the mechanism illustrated on the accompanying sheets of drawings, and in which- Figure 1, is a perspective view of the device as adapted for supporting a circular saw guard. Fig. 2, is a similar perspective view of the adaptation of my invention for carrying a shaper guard.

Like reference characters designate the same parts in both figures.

According to the form of my invention, shown by Fig. 1, the semi-circular shield or guard 1,a portion only of which is shown as it forms no part of my present invention-consists of two semi-circular plates placed far enough apart to allow the saw to operate between them. At the top portion of the guard l, are two upstanding lugs 2, 2, between which is hingedly connected by a pin 3, the lower end of an obliquely disposed and resiliently controlled slidable bar 4. This bar 4, is adapted for axial movement in a sleeve bearing 5, formed intergal with a bracket arm 6, hereinafter referred to. In order to make ready provision for the axial Specification of Letters Patent.

Application filed July 29, 1912.

Patented Feb. 25,1913.

Serial No. 712,169.

movement of the slidable bar 4, I arrange around the said bar a spiral spring 7 which abuts between one end 8, of the sleeve bearing 5, and one flange 9, of a channel shaped retaining member 10, secured on the bar 4, by a clamping screw 11. This retaining member 10, is arranged as shown, that is to say it is longitudinally mounted with the one flange 9, at one end of the bearing sleeve 5, and the other 12, at the other end thereof, all of which will be fully understood from an inspection of the drawings. 13, is a split or cotter pin for preventing the accidental displacement of the bar 4, during adjustment.

At the upper end of the bracket arm 6, I form a corrugated or toothed shaped circular head 14, adapted for coupling connection by a clamping screw 15, to a correspondingly corrugated or toothed head grip 16, formed integral with a rectangular shaped sleeve 17, by means of which the device is slidably and adjustably mounted on a rectangular shaped horizontal bar 18,supported by appropriate brackets and guy rods from the ceiling or other suitable place. A set screw 19, on the top of the sleeve 17 clamps the latter anywhere desired on the horizontal bar 18.

On an examination of Fig. 2, it will be seen that the only diiference from Fig. 1, is that the slidable bar 4, is arranged vertically and the bracket arm obliquely; or, in other words, the positions of said parts as applied to a shaper guard are reversed, whereas their action is the same. 20, is a fragment of the shaper cutter guard, and it is clamped to the end of the bar 4, by a set screw 21.

From the foregoing description and accompanying drawings it will be readily seen that my device is equally adapted for use with one or more gangs of saws or shapers, while at the same time it is convenient to adjust or to throw out of the way when changing saws, cutters or the like.

A further feature to be noted is the fact that by resiliently mounting the slidable bar 4, as set forth, the device is rendered automatic so far as operating upon diiferent or varying thickness of material is con cernecl, as the guards 1 and 20, will adjustthemselves automatically thereto.

Obviously the details of construction as well as the arrangement and combination of parts may be modified without in any way departing from the spirit and scope of the invention, and it is intended to include all such Within the present application and as limited by the appended claims.

Having thus fully described my invention, what I claim as new and desire to se cure by Letters Patent, is

1. In a device of the character described, the combination with a protective element, of a resiliently mounted slidable bar attached at its lower end to said protective element and passing through a sleeve on a depending bracket, a flanged retaining member for limiting the movement of said slidable bar inopposition to resilient means and adapted to be clamped thereto, a corrugated face block integral with the upper end of the depending bracket, a second corresponding corrugated face block integral With a horizontally disposed sleeve, means for clamping said face blocks in adjusted relation, and means for fixing the entire clevice above the cutting tool, substantially as set forth, for the purpose specified.

2. In a device of the character described the combination with a protective element, of a resiliently mounted slidable bar of rectangular cross section attached at its lower end to said protective element and passing through a similarly shaped sleeve on a de pending bracket, a channel shaped retaining member mounted on said slidable bar and adapted for limiting the movement thereof in opposition to spring pressure by clamping engagement thereon, a corrugated face block integral with the upper end of the depending bracket, a second corresponding corrugated face .block integral with a horizontally disposed rectangular sleeve, means for clamping said face blocks in ad-' justed relation, and means for fixing the en tire device above the cutting tool, all substantially as described and shown for the purpose specified.

Signed at Hamilton, Ontario, Canada, this 27th day of July, A. D. 1912.
