STOCK-GAGE.

Specification of Letters Patent.

Patented July 1, 1919.

Application filed December'30, 1916. Serial No. 139,787.

to' structure of this character intended for use in con unctlon with a up saw, planer, or

other machine in which stock is to be run through in the line of its length, the gage being so constructed that it will also act as a uide.

in object of my inventiton is to provide a gage which is so constructed that it can be made as an attachmentto be applied to' saws or other machines already in use, or WhlCll mlght be embodied in the machine as manufactured, and which has the parts thereof so constructed and arranged that a plurality of gage blades adapted to be set to be presented as stock guides at various points of disposition from the saw or other tool, are included and are mounted to be brought selectively to the position for use.

.A further object resides in providing means by which the various gage plates can be adjusted to give the desired setting thereto, and which means is so arranged that very minute adjustments can be obtained and the accurate setting of the ma-' chine may thus be accomplished.

In the drawings:

Figure 1 is a plan view showing the gage structure with the various gage plates each moved to the lowered position.

Fig. 2 is a sectional view taken on the line 22 of Fig. 1.

Fig. 3 is a vertical sectional view on the line 33 of Fig. 2.

Fig. 4 is a detail perspective view show ing the formation of the eye by which the supporting rods are mounted.

Fig. 5 is a fragmentary perspective view showing a modified form of the construction as disclosedin Fig. 4.

A base member 1, which is preferably made of substantially angle iron form, has

the bearings 2, 3 and 4 thereof provided with alined openings. This base member 1 can be secured upon the stock supporting bed of a saw, planer, shaper, or other woodworking machine, and the alined bearing openings are to be disposed parallel "withthe line of movement of the stock as fed through the machine. 5, 6, 7, 8, and 9, are shaped at their ends to provide the bearing portions 10 having the bearing eyes 11 therethrough, and these bearing portions are so formed that the several supporting rods can be fitted between the bearings. 2'and 3 of-the bas portions 1, spaces. or spacing collars, 12, being provided to hold the supporting rods equally spaced. Supporting rods 13, 14, 15, 16, and 17 are made of substantially the same form as the members 5 to 9 inclusive, and it is intended that the supporting rods 5 and 13, the rods 6 and 14, etc., shall be considered as a pair. The supporting rods 13 to 17 inclusive are mounted between the bearings 3 and 4 and are held spaced apart by the spacers 18. A shaft 19 is made of such size that it fits snugly through the openings of the bearings 2, 3 and 4, and the eyes 11 of the several supporting rods are made of such size that as this shaft 19 is fitted through the bearings, the supporting rod, and the spacers 12 and 18'of the two groups of supporting rods, the rods mayliave free swinging movement. To insure that the supporting rods will turn individually, or rather that the two bars of each set will swing without causing the remaining bars to be moved, it is of course necessary that the spacers 12 be fitted loosely between the supporting rods, although these spacers must hold the parts against loose movement or play, and also it is preferable that the set screws 20 be provided in the hearings to lock the shaft 19 against turning. Spacing rods 21, 22, 23, 24, and 25, are provided to pair with the supporting rods 5 to 9 inclusive, and each of the rods 21'to 25 inclusive is provided with right hand'threads onone end, while the rods 5 to 9 inclusive have left hand threads ofsubstantially the same pitch formed on the free end thereof. Adjusting nuts 26, 27, 28, 29, and 30 are preferably made of hexagonal or other polygonal form, and are oppositely screw threaded at their ends so that the paired rods can be fitted therein and as these adjusting nuts are turned, the spacing rods of various pairs will be extended or withdrawn. It is essential that the supporting rods 5, 6, 7, 8, and 9, and the corresponding supporting rods 13, 14,15, 16, and 17 of each pair, be made of equal length, and that the rods of the various pairs be preferably made of such -length that each successive The supporting rods pair has greater extent from the shaft 19. The supporting rods, 13 to 17 inclusive have the spacing rods 31, 32, 33, 34, and 35' paired therewith, and these spacing rods together with. the supporting rods paired therewith are oppositely screw threaded, the adjusting nuts 36, 37, 38, 39, and 40 being mounted to accomplish the extension and withdrawal of the spacing rods in the same manner as hereinbefore set forth in connection with the first mentioned group of the spacing and supporting rods. It is preferable that each of the spacing rods be of substantially the same length and thus these parts can be made duplicate, as may also the adjusting nuts. The outer ends ofthe various spacing rods are screw threaded, and the gage plates 41, 42, 43, 44, and 45 are provided with screw threaded openings to have the spacing rods screwed thereinto in such manner that the gage plates will be rigidly mounted. The spacing rods 21 and 31 connect with the gage plates 41, rods 22 and32 are secured to the plate 42, rods 23 and 33 are secured in the orifices of the plate 43, spacing rods 24 and 34 carry the plate 44, and rods 25 and 35 have the plates 45 mounted thereon.- By the mounting of the plates in the manner as set forth and the connection of the spacing rods to the supporting rods through the medium of the adjusting nuts, the plate 41 is carried by the shorter set of supporting rods constituting rods 5 and 13, plate 42 is carried by the next longest setwhich includes the rods 6 and 14, plate 43- is carried by rods 7 and 15, plate 44 by rods 8 and 16, and the gage plate 45 is mounted to be carried by the supporting rods 9 and 17. As has been stated, the rods of each pair are of substantially equal length, but the various pairs of rods are each of slightly different length from the remaining pair, and thus the gage plates are so disposed that plate 45 is outermost, plate 44 is next, and then plates 43, 42, and 41 are held successively nearer tothe base 1. It is to be understood that each of the gage plates is cut out at its top edge as is shown in Fig. 2, in conjunction with the plate 41, so that the spacing rods of the remaining plates disposed outwardly be; yond the inner plates can come down to present the lower edges of the plates against the top of the work supportitng table and to, dispose the gage plates to extend substantially in a Vertical plane from the table or at any desired angle therefrom.

Each spacing rod has the lock nuts 46 mounted on the outer screw threaded ends thereof to be brought to jam against the inner sides of the gage plates, and thus the spacing rods will be locked to be mounted rigidly in conjunction with the plates, but at the same time, the plates are so mounted that in .case of wear or in case it may be desired to change the plates for any reason, they may be readily detached and refitted, or other plates may be mounted in lieu thereof. The adjusting nuts are preferably made quite long and sleeve like so that quite a considerable length of the supporting and spacing rods can be fitted therein, and thus greater length of adjustment is provided and at the same time the paired spacing rods and supporting rods are in alinement and twisting or shifting movement of the plates is precluded. To insure that the adjusting nuts will be held in the position to which they are adjusted, the lock washers 47, which areof any desired type, are mounted on each of the supporting rods and then the jam nuts 48 are provided to be tightened against the lock nut to positively secure the adjusting nuts against casual or accidental readjustment, it of course being understood that where readjustment is desired, to be made the lock nuts can be loosened and then turning of the adjustingmuts of each of the sets of paired spacing and supporting rods will give proper adjustment either from or toward the shaft 19 and will make it possible to attain a parallel setting with respect to the line of movement of the stock in passing through the machine.

In Fig. 5, I have illustrated a slightly modified form of the bearing for the supporting rod, and as is here shown, a block 49 constitutes a bearing portion and is bored through to provide an opening to receive the supporting rod. The supporting rod can be screwed into this block or secured in any other way, it of course being understood that the supporting rods must be held rigidly in conjunction with the blocks and must also be secured against turning movement. The bearing openings 50 may be provided in the block 49, and preferably adjacent one end thereof, and thus the parts are so arranged that as the gage plate carried by the supporting rod may be swung up to the inoperative relation, the block 49 will permit the plate to be swung past a dead center directly over the shaft 19 and then the rear portion of the block will strike against the base portion 1 and in this position the plate will be held elevated and in the inoperative relation. Where the supporting rods are made of the form shown in Fig. 4 at their bearing ends, any suitable means might be provided to hold the rods in an elevated and upright position when the gage plates are brought to the inoperative relation, or the rods and the plates carried thereby might be swung entirely over the shaft 19 to rest upon the work supporting table or bed of the machine on which the gage is fitted.

This gage adapts itself particularly for usein conjunction with a rip saw for cut ting sash and door stock which is desired to have different widths in different parts, in conjunction with a planer or shaper to hold stock of various widths which is to be operated upon at the edge or side edges, upon the shaper, and in a number of other connections. The device might be constructed as an attachment to be applied to a machine already in use, and it will then be understood that securement of the base structure 1 can be made in any manner desired, or the structure might be embodied in the machine as being constructed and manufactured. In use, the jam nut 48 will be .loosened, and then the adjusting nuts will be turned to give the proper fitting to the gage plate after which the jam nuts may be again tightened into place and the adjustment will be secured and locked. When it is desired to use the plate 41, the remaining gage plate will be swung over and up to bring the same from the position adja-- cent the cutter of the machine, and then the face of the plate 41 is presented to form a gage to properly locate the stock with respect to the cutter and a guide to insure that the stock willbe carried through the machine in a proper path. If the plate 43 is to be employed, plates 41 and 42 will be swung down and plates 44 and 45 will be retained in the raised or swung back relation, and the gage plate 43 is then disposed adjacent the cutter in a relation to accomplish an eflicient gaging and guiding of the stock. When other of the gage plates are to be brought to the position for use, it will of course be understood that this will be accomplished in the same manner as specified in conjunction with the two illustrative settings as mentioned. I

While in the foregoing. I have shown and described only specific forms which the invention might take, it will be understood that a greater or lesser number of plates might be employed, that the spacing rods might be secured integrally therewith, that the form of the supporting rods might be changed, and that a number of other variations and modifications might be resorted to in the form and arrangement of the parts without departing from the spirit and scope of my invention, and hence I do not wish to be limited to the exact disclosure but only to such points as may be set forth in the claims.

I claim:

1. In a device of the class described, the combination of a base, a shaft carried by said base, a plurality of supporting rods arranged in pairs and having bearing portions on their inner ends, said bearing portions being carried by said shaft, elongated adjusting nuts screwed onto the forward ends of said rods, spacing rods carried by the forward ends of said nuts, and a plate carried on the forward ends of each pair of said spacing rods, whereby when said nuts are rotated said spacing rods will be moved either toward or away from the supporting nods, whereby said plate will bet moved away from or toward said base.

2. In a device of the class described, the combination of a supporting base having a shaft, two series of supporting rods pivotally mounted upon said shaft, the rods of each series starting from one side of the series and increasing progressively in length toward the opposite side of the series, whereby corresponding rods of the two series will be of equal length, elongated adjusting nuts screwed onto the forward ends of said supporting rods, spacing rods of equal length carried by the forward ends of said adjusting nuts, plates fixed on the forward ends of said spacing rods, said plates having reduced upper portions, whereby the spacing rods connected to the longer supporting rods will pass above the plates carried by the spacing rods connected to the shorter supporting rods, thus allowing desired ,plates to be placed foremost by the extension of the spacing rods above plates not to be used, although when plates carried by the short supporting rods are to 'be used, the plates carried by the spacing rods connected to the longer supporting rods may be swung rearwardly, while the adjustment of said nuts will accurately adjust a desired plate with respect to its distance from said base.

3. In a device of the class described, the combination of a shaft, means for supporting said shaft, a pair of supporting rods pivotally mounted upon said shaft, elongated adjusting nuts screwed onto the forward ends of said rods, spacing rods carried by the forward ends of said nuts, and a plate carried on the forward ends of said spacing rods, whereby when said nuts are rotated, said spacing rods will be moved in either of two directions, whereby said plates will be moved away from or toward the said shaft, and said supporting rods being capable of being swung on said shaft to move the plates to inoperative position.

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