PETER ERIGKSON, OF CHICAGO, ILLINOIS.
SHAPER-GUARD.
Specification of Letters Patent.
Application filed September 27, 1911.
Patented May '7, 1912.
Serial No. 651,524.
To all whom it may concern Be it known that I, PETER ERIGKSON, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Shaper-Guards, of which the following is a specification.
My present invention relates particularly to an improvement in that character of devices commonly known as shaper guards and described and claimed in my Patents Numbers 925,319 and 987,452, respectively, dated June 15, 1909, and March 21, 1911.
The present improvement has for its principal object the rearrangement and adjust able connection of the part-s in order to promote simplicity in construction and operation and quick and easy manipulation and adjustment. These and other objects will be apparent from the accompanying drawings, in which Figure 1 is a top plan view of my 1111 proved construction and a portion of the shaper to which it is attached. Fig. 2 is a side elevation. Fig. 3 is a sectional view taken on the line 33 ofFig. 1, and Fig. 4 is a central vertical section through the guard holder.
Referring specifically to these figures, 1 designates the shaper table or top, upwardly through which extends the cutter or shaper head 2 having blades 3. Secured to, and upstanding from the table 1 is a frame or stand 4, having connecting bolts 5, and on the upper portion of which are revolubly mounted tubular horizontal bearing members 6, held by pivot bolts 7 and having squared bores 8 adapted to receive the re spective ends of squared arms 9. The arms 9 are adj ustably secured within the members 6 by clamping screws 10 and each carry a similar guard mechanism, but as each of these mechanisms is identical, the further description will have to deal with only one of them. Adjacent to the outer end of the arm 9 is a clamping bolt 12 and at the eX- tremity of said arm is a pivot bolt 12, the latter extending through a conformable opening in a segmental plate 11, and the former extending through an arouate slot 13 in said plate so as to secure the same in selected angular adjustment. This plate 11 is provided with a vertical tubular bearing 11* for the reception of the guard-holding tube 14, one side of said bearing being apertured to receive a movable clamping plug 11 movable between ribs 11", to frictionally grip the periphery of said tube under action of the intermediate eccentric portion of a pin shaft 11 having a handle 11 The upper and lower ends of the adjustable guard-holding tube 14 are partially closed by apertured bushings 15, through the apertures of which extends a shaft 16, the upper end of which is threaded and provided with an adjusting nut 17 bearing downwardly upon the upper bushing 15. This shaft 16 is also provided with a spring'18 coiled thereabout and compressed between an intermediate collar 19 and the upper bushing 15, and with a second spring 20 coiled thereabout below the lower bushing 15 and above the segmental shoe 21 to which is attached the guard 22. Thus the spring 20, which is normally inactive may be brought into play by screwing down the nut 17 a su'liicient dis tance when its pressure is desired in addition to that of spring 18, it being had in mind that tube 14 may. be adjusted vertically in such case by the members 11 and 11. The shaft 16 may also have upper and lower pairs of transverse pin shafts extending therethrough at right angles and carrying rollers 23 operating in slots 24 in the bushings 15. Also revolubly secured upon the stand 4, by means of a bolt 26 is an arm 27 having, at its outer end, a bearing 28 to receive one end of an arm 30, and a clamping screw 31 to adjustably hold said arm. At its opposite end, arm 30 has a vertically disposed clamping eye 33 to adjustably hold the upper end of the stem 35 of the gageholding plate 34, carrying the gage 37.
In practice the gage 37 is properly adjusted by means of its connections at 26, 28 and 33, and the guard 22, which also acts as a presser foot, is also properly adjusted by means of its adjust-able shaft 16, holder 14, plate 11, and arm 9 with its revoluble connection at 6, the supplemental spring 20 being brought into operation when necessary, as before described. From this it will be seen that the device is simple both in construction and operation, is of a durable nature, and is capable of quick and easy adjustment.
I claim:
1. In a shaper guard, the combination of a supporting stand, an arm having a lengthwise adjustable and revoluble connection with said stand, a plate having an angularly adjustable connection with said arm, a
guard, a shaft to which said guard is connected, a tubular guardholder having an adjustable connection With said plate and through Which said shaft is mounted, and means to tension the movement of said shaft.
2. In a shaper guard, the combination of a supporting stand, a bearing member revolubly mounted on said stand, an arm adjustably connected to said bearing member, a plate having an angularly adjustable connection With said arm, a guard, a shaft to Which said guard is connected, a tubular guard holder having an adjustable connection with said plate and through which said shaft is mounted, a spring compress between a portion of said holder and a portion of said shaft to tension the latter, a supple- PETER ERIOKSON.
