To aZZ whom it may concern:

Be it known that I, HERMAN ADOLF WOLF- RAM, a citizen of the United States, residing at \Vest Troy, in the county of Albany and State of New York, have invented a new and useful Improvement in Adjustable Gages, of which the following is a specification.

My invention relates to an improvement in adjustable gages for sawing boards to make cigar-boxes, and it consists in the peculiar construction and combination of devices,that will be more fully set forth hereinafter, and particularly pointed out in the claims.

In the drawings, Figure 1 isatop plan view of an adjustable gage embodying my improvements attached to a machine for sawing cigarbox lumber. Fig. 2 is a front elevation of my improved adjustable gage. Fig. 3 is a transverse vertical sectional viewof the same, taken on line 00 a: of Fig. 1. Fig. 4 is a top plan view of my gage, showing the same in a difierent position from that shown in Fig. 1. Fig. 5 is a detail view of a portion of the gage. x

A represents the top of the saw-machine,the said top being adapted to slide horizontally and provided at its rear side with a vertical projecting flange, B. Across the center of the movable top is made a slot, 0, through which projects the upper edge of a circular erosscutsaw. The flange B is provided at one end for a suitable distance with a horizontal slot, D.

E represents a rectangular block, which forms a part of the base of the gage, and is provided on its rear side with a horizontal tongue, F, which is adapted to enter the slot D of the saw-table. A screw, G, projects from the rear side of the tongue, and to the rear end of the said screw is secured a clamping thumb-nut, H, the function of which is to rigidly clamp the block E to the flange B at any desired distance from the kerf or slot 0 in the top of the saw-table. On the front side of the block E is attached a metallic bar, I, which projects beyond one end of the block for a suitable distance, and is provided on its upper and lower sides with longitudinal grooves K.

L represents an adjustable block, which is similar in size and shape to the block E, and is provided on its front side with the horizontally-arranged guide-plates M, having tongues on their opposing edges, which enter the grooves K of the bar I. By this means it will be read ily seen that the block L is secured to the bar I, and is adapted to slide thereon toward and from the block E. The outer edge of the block L is provided with a metallic face-plate, O, to prevent wear. In the outer end of the bar I is made a longitudinal-slot, P, the length of which corresponds to the desired space through which the gage is to be adjusted. A screw or pin, R, projects from the block L and extends through the slot P.

S represents a coiled retractile spring, which has one end attached to the screw or pin R, and the opposite end attached to the screw or pin T, that projects from the front side of the bar I. The function of this spring is to normally draw the adjustable gage-block L toward the base-block E. Through the latter extends a longitudinal adj usting-screw,U, the outer end of which projects beyond the outer end of the block E and is provided with a milled head. Theinner end of the screw projects through the metallic plate V, which is attached to the inner end of the block E and works in a threaded opening which is made in the said metallic plate, and bears against a wear-plate, W, which is attached to the inner end of the adjustable gage-block L.

X represents a metallic plate, which is screwed to the upper edge of t-heblock E, and is provided at its inner end with diverging arms Y and Z, which are arranged on opposite sides of the adjustable block L. The arm Z is provided at its outer end, on its upper side, with a projecting stop or stud, A, and in the said arm, at a suitable distance from the said stop or stud, is an opening, B.

C represents a spring-arm, which is pivoted at its inner end upon a screw, 1), which enters the arm Z at a suitable distance from the outer end thereof. The said arm Z is provided near its outer end,on its outer side,with a pr0- jecting lug or offset, E, in which is made an opening, F, which is arranged by the side of the opening B. The spring-arm O is provided on its upper side with a projecting detent, G, which is adapted to enter either the opening B or the opening F, and at the outer end of the spring-arm is a knob, H, by means of which the spring-arm may be pressed from the arm Z, so as to disengage the detent from the opening B or F.

1 represents a lever-arm,- which is fulcrumed to the upper side of the adjustable block L upon a screw or pin, K. The short arm of the lever is pivotally connected-to-the outer end of the arm Y on a screw, L, which projects from the upper side of the said arm Y. The long arm of the lever I bears upon the upper side of the arm Z, and is adapted to move upon the said arm Z, and is provided with a handle, M. I

The operation of my invention is as follows: In cutting lumber for cigar-boxes it is necessary to saw three lengthsone for the front and back of the box, and another for the top thereof, which must be one thirty-second part of an inch shorter than the front and back, in order to leave a suitable space between the ends of the cover and the ends of the box for the edging paper, which is pasted on the cover, and to enable the cover to open freely. The length of the bottom of the box must exceed the length of the front and back thereof by a distance equal to twice the thickness of one end Wall of the box; and in order to enable the gage to be instantly adjusted to either of these required lengths and to be shifted from one to the other without getting out of place, I have provided the devices hereinbefore described. When proceeding to saw lumber to make cigar-boxes, the adjusting-screw U,is first set to the desired adjustment, so as to cause the gage-block L, to stop when it comes within the required distance of the block E,thus allowing the block L, to play back and forth through a space equal to twice the thickness of the material to be sawed. The gage is adjusted by sliding the tongue F, in the slot D,until the distance from the face-plate O to the slot or kerfO in the sawtable' is equal to the required length of the fronts and backs for the cigar-boxes, when the lever-arm Iis engaged by the spring'actuated detent projecting up through the opening F in the arm Z. After the fronts and backs have been sawed, the spring-arm G is moved inwardly so asto cause its detent to project up through'the opening B. This brings the detent nearer to the fulcrum of the lever-arm I, and consequently moves the adjustable block one thirty-second part of an inch nearer to the slot 0, and thereby causes the tops for the boxes to be sawed one thirty-second part of an inch shorter than the backs and fronts thereof, for the reason hereinbefore described. After the tops have been sawed, the knob at the outer end of the spring-arm is depressed, so as to lowerthe detent in the opening B and cause the said detent to release the lever-arm I, when the spring S instantly draws the block L toward the block E, until the said block L comes in contact with the end of the adj ustingscrew U, thus moving the gage-block Lfarther from the slot 0 in the saw-table top by a distance corresponding to twice the thickness of ends of the bottoms thereof From the foregoing description it will be understood that the gage may be moved from one adjustment to the other instantly and without the danger of its getting out of position, the changes of the gage being thus enabled to be made without the necessity of tak-' ing any measurements after the gage has been once adjusted.

Having thus described my invention, I claim 1. In an adjustable gage for cigar-box-sawing machines, the combination of the baseblock E, the gage-block L, connected thereto and movable toward and from the base-block, said base-block having the arms Y Z on opposite sides, the lcver-arml, fulcrumed to arm Yand connected to the gage-block, and the detent on the arm Z, to lock the lever-arm at different adjustments on the arm Z, substantially as described.

2. In an adjustable gage for cigar-boxsawing machines, the combination of the baseblock having the bar I projecting beyondwone end thereof, the gage-block secured to the said bar and movable thereon, the spring con necting the gage and base blocks to draw the former toward the latter, and the adjustingscrew in the base-block bearing against the gage-block, for the purpose set forth, and the mechanism to move the gage-block in opposite directions, substantially as described. 1

3. In an adjustable gage for cigar-box-s'awing machines, the combination of the baseblock having the arms Y Z on opposite sides. the latter arm having the radial openings E and F, the gage-block movable toward and from the base-block, the lever-arm I, fulcrumed to arm Y and connected to the gageblock, and the spring-arm G, pivoted to arm Z, and having the detent G to enter either of the openings E and F and lock the lever I, for the purpose set forth, substantially as de- "scribed.

4. The combination of the sliding saw-table top having the flange B at right angles to the saw, with the base-block clamped to the flange and adjustable thereon, the gage-block connected to the base-block, the spring to normally move the gage block toward the base-block, the screw to limit the rearward movement of the gage-block, the fulcrumed lever connected to the gage-block to move the same, and the detent to lock the said lever at different adjustments, substantially as described.

5. The combination of the base-block having the diverging arms Yand Z projecting from one end, the said arm Z having the openings B and F, the gage-block movable toward and from the base-block, the lever-arm fulcrumed to arm Yand connected to the gage- IIO block, and the spring-actuated detent adapted to project from either of the openings B and F and engage the lever-arm, for the purpose set forth, substantially as described, for

gage-block, the lever-arm fulor'umed to the arm Y and connected to the gage-block, and 1.5 the detent attached to the arm Z, to engage the lever-arm at different adjustments, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in pres- 2o ence of two witnesses.
