ATTACHMENT FOR GRADUATED RULES.
SPECIFICATION forming part of Letters Patent-No. 457,077, dated August 4, 1891. Application led October 2, 1890. Serial No. 366,839. (No model.)
To all whom t may concern,.-
Be itknown that I, MENS A. DAHL, a subject of the King of Norway, residing at Vest Orange, county of Essex, and State of New J ersey, have invented certain new and usefulImprovements in Attachments for Graduated Rules; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specication.
The object of this invention is to simplify measurements as taken by a graduated rule and enable the workman to keep continually the same exactness of measure.
The invention consists in the improved attachment for graduatedrules and the com# bination and arrangement of parts thereof, substantially as hereinafter described, and finally embodied in the claims.
Referring to the accompanying drawings, in which like letters of reference indicate corresponding parts' in each of the several Iigures, Figure l is a plan view of my improved device attached to a graduated rule. Fig. 2 is anunder side view of Fig. l. Fig. 3 is an enlarged section on fr Fig. l. Fig. 4 is an enlarged section on line y y', Fig. l; and Fig. 5 is an enlarged section on line a, Fig. l.
In said drawings, A represents the graduated rule, on which is arranged' my improved independent adjustable gage attachment. This attachment consists of an elongated grooved block a, adapted to slide on one side of the graduated rule A. The under side of the block is recessed,as shown in Fig. 2, to allow the adjustment and arrangement of a spring-rod f. On the under side of the upper portion of the block ct is secured in any desired manner a iiat spring b, adapted to rest on the surface of the rule A. In the top portion of the block Ais a threaded opening, in which works a threaded adjusting-screw c, the lower end of said screw resting on the spring b, so that by turning down the screw the attachment will be nally held on the rule, as will be manifest. In one end of the block a is a dovetail slot d, in which is adjusted a sliding block e. This block e is secured to one end of the spring-rod f, and is formed on one side with a sharp knife edgeor point g. (Shown in Fig. 5.) This knifeedge rests in one of the graduating-marks on the rule A, and is held there by the action of the spring f. In the front of the block a is a sharp-pointed marking pin or projection h, with a Hat side and so arranged that this flat side shall be on a line exact with the end of the block. The pointed marking pin can also be used for marking the gage distan ce ou other objects.
In operation the screw c is loosened, thereby releasing the spring b. The block a is then moved to the exact distan ce required between the side of the block and the end of the rule. 'The sharp edge of the block e will then enter the gage-mark on the rule and he held in place by the spring f. The screw c will then be turned down and hind thebloclr a firmly to the rule A. In this manner the workman will always have a uniform gage and one that is not shifting, and it will not be necessaryjo examine it every time itis used to see that it is exact. Vhen two ofthe attachments are used, they will be adj usted right and left, and in this manner can be used as a beam-compass.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is r l. Inra gage attachment, the combination, with a graduated rule, of an independent adj ustable gage-block provided with a sharp edge adapted to engage inl the notches of said graduated rule, and means for securing said gage-block to the graduated rule, substantially as described and set forth.
2. In a gage attachment, an independent adjustable gage-block combining therein a block adapted to be adjusted on a graduated rule and provided at one end with a slot, a block working in said slot and provided with a sharp edge adapted to engage in the notches of said graduated rule, a spring arranged to hold said sharp edge in said notches, and means for securing said gage-block to a graduated rule, all said parts being arranged and adapted to operate substantially as described and set forth.
3. In a gage attachment, an independent adjustable gage-block combining therein a IOO block adapted to be adjusted on a graduated rule and provided at one end with a slot, a block Workingin said slot and provided with a sharp edge adapted to engage in the notches 5 of said graduated rule, a spring arranged to hold said sharp edge in said notches, a marking-pin secured to said gage-block, and means for securing said gage-block to a graduated rule, all said parts being arranged and adapted to operate substantially as described and xo set forth.
In testimony that I claim the foregoing I have hereunto set my hand this 27th day 0f September, 1890.
MENS A. DAHL. Witnesses:
ALFRED GARTNER, ALBERTA. SCHMIDT.
