WILLIAM HOOK, OF SIDNEY, OHIO, ASSIGNOR OF ONETHIRD TO RANSOM D. EARL AND ONE-THIRD TO EDWARD S. MCCLURE, BOTH 0F SIDNEY, OHIO.

RIP-SAW SHIELD.

To @ZZ fui/tom 'it may concern Be it known that I, WILLIAM IIooii, a citizen of the United States, residing at Sidney, in the county of Shelby and Stato of Ohio, have invented new and use't'ul Improvements in Rip-Saw Shields, of which the following a specilication.

This invention relates to guards or shields for circular rip saws, the object of the invent-ion being to provide a device of this character which is simple of construction, reliable and eiticient in operation, which will protect the attendant or sawyer against liability of injury, and which will also prevent objectionable dissipation of the sawdust.

The invention consists of the features ot construction, combination and arrangement or' parts hereinafter fully described and claimed, reference being had to the accompanying drawings, in which Figure l is a side elevation illustrating the application of the invention in connection with a circular saw, a portion of the saw frame being disclosed. Fig. 2 is a top plan view of the same. Fig. 3 is a vertical transverse section on the line 3dB of Fig. 1. Fig. 4L isa similar view taken substantially on the line t-ll of Fig. 1. Figs. 5 and 6 are perspective Views of the dust shield and abutment plates.

Referring to the drawings, 1 designates a circular saw, and 2 a portion of the supporting frame of the saw. To this frame portion are secured a pair of spaced bracket plates 53, each of which is vertically disposed and provided with a longitudinal sl ot hl, each of said bracket plates also having at its upper end a horizontal portion 5 projecting above the upper edge of the frame portion Bolts t3 provided with washers 'i' and wing nuts 8 pass through the :trame portion 2 and slots I in the bracket plates, and adj ustably secure said plates to the trame, so that the plates may be raised and lowered to the desired degree.

Arranged upon the outer side ol and parallel with the trame portion 2, and also parallel with the saw l, is an abutment plate 9, which is disposed between the saw and the frame portion 2 and forms a bearing or rest for the timber which is being sawed. This abutment plate is provided at its upper edge with inwardly extending horizontal arms 10, which rest upon the horizontal por- Speccation of Letters Patent.

tions 5 of the bracket plates 3 and are provided with longitudinal slots 11.

Arranged horizontally above the saw is a shield plate 12, which covers and overhangs the space between the trame portion 2 and abutment plate 9 and extends at :its outer edge beyond the latter, at which edge said shield is provided with a downturned portion 13. In proximity to its inner edge the shield plate is provided with slots 14 which register with the slots 11 in the arms 10 of the abutment plate 9. Through these slots in the shield. and abutment plate arms pass bolts l5, which extend upwardly through openings in the horizontal portions 5 of the bracket plates 3 and are fitted with clamp ing washers 1G and wing nuts 17, whereby the abutment plate and shield are adjustably secured to the trame, so that they may be disposed relatively thereto to accord with variations in the distance between the frame portion 2 and the saw, as well as to dispose the shield to operate with the greatest advantage.

By means of the abutment plate 9 the timber which is being sawed may be accurately O'uided and lirmly held in position while t ie saw is operating thereon, and by means of the plate l2, the dust rising 'from the work will be thrown down and prevented from scattering in the air, and from being inhaled to any material extent by the attendant or sawyer. The shield 12 also acts as an overhanging guard by which liability ot injury to the sawyer is diminished. In order to lurther protect the sawyer I provide a vertical guard plate 18, which is mounted upon the outer surface oiE the abutment plate 9 in line with the saw and diametrically opposite the working portion of the perij'ihery ol the saw. This plate has an inner curved edge 19, for an obvious purpose, and is provided with a longitudinal slot 20 for the passage of ay bolt 21 extending through an opening in the abutment plate, said bolt serving to pivotally and adjustably connect the guard plate to the abutment plate. As shown, the bolt is provided with a washer 22 and wing nut 23, whereby the guard plate may be clamped in adjustu ed position.

Frein the foregoing description, the construction and mode of use of my improved saw guard or shield will be readily understood, and it will be seen that the invention provides a device of this character which is simple of construction, reliable and etiicient in action, adapted to guard the sawyer from injury and the inhalation of dust, and capable of being adjusted to suit different requirements of service.

I claim 1. In a saw guard, the combination of a circular saw, a saw frame, brack-ets vertically adjustable on the saw frame, a Vertically disposed abutment plate disposed between the frame and saw and having horizontal arms resting upon the brackets, ahorizon tal shield plate overhanging the space between the frame and abutment plate and projecting outwardly beyond the latter, and clamping devices for securing said abutment. plate and shield plate to the brackets, and for permitting adjustment oi said plates in a direction toward and from the frame.

2. In a saw guard, the combination of a circular saw, a frame, vertically disposed brackets adj ustably secured to the :trame and having horizontal portions extending from the top thereof, a vertically disposed abutment plate arranged parallel with and on the outer side of the frame, said plate being provided with inwardly extending slotted horizontal arms, a horizontally disposed circular saw, a frame, brackets carried by the frame, a vertically disposed abutment plate disposed between the saw and frame and adjustably connected with the brackets,

a horizontally disposed shield plate adjustably supported by the brackets and overhanging the space between the frame and abutment plate and extending outwardly bev yond the latter, a slotted sawguard carried by the abutment plate, and means adjustably securing said saw guard thereto.

In testimony whereof I aiiix my signature in presence of two witnesses.

WILLIAM HOOK.
