3 Claims.
This invention relates to a horn micrometer, and more particularly to such a device adapted for the measuring of relatively large distances with a small-sized micrometer.
An important object of this invention is the provision of a horn micrometer characterized by means whereby increase or decrease in the size thereof may be readily effected without affecting the accuracy of the measurements.
A further object of the invention is the provision of such a device which will obviate the necessity for use of Johansson blocks in connection with such a micrometer.
Still another object of the invention is the provision of a horn micrometer which is readily adaptable for the measuring in micrometric dimensions of the distance of holes or the like from the sides of pieces of material.
Still other objects will in part be obvious and in part be pointed out as the description of the invention proceeds, and shown in the accompanying drawings, wherein there is disclosed a preferred embodiment of this inventive concept.
In the drawings:
Figure 1 is a side elevational view of one form of horn micrometer embodying features of the instant invention.
Figure 2 is a sectional view taken substantially along the line 22 of Figure 1, as viewed in the direction indicated by the arrows.
Figure 3 is a sectional view taken substantially along the line 33 of Figure 1, as viewed in the direction indicated by the arrows.
Figure 4 is a sectional view taken substantially along the line -44 of Figure 1, as viewed in the direction indicated by the arrows.
Similar reference characters refer to similar parts throughout the several views of the drawings.
Referring now to the drawings, there is generally indicated at ID a conventional micrometer barrel, including a ratchet H, a thimble l2, and a spindle l3, extending through a yoke piece I4 provided with a conventional spindle lock IS. The yoke piece 14, instead of extending in the conventional manner in an arc to the handle, extends downwardly terminating in a rectangular portion 16, having channels l1 therein for the accommodation of spaced parallel rods 18. The rods 18 are of any desired length, but preferably about six inches in length, and extend into suitable apertures 20 in a block 2|, comprising the base of a horn handle 22 terminating in an anvil pin 23. The opposite ends of the rods are secured in related assembly, as by a plate 25, and
2 a lock nut 26 which engages the threaded extremity 21 of one of the rods.
Obviously, any desired number of blocks within the normal limits of the device may be utilized or removed therefrom, as desired.
Suitable transverse pins 35 may be utilized, if desired, to secure the ends of the rods in theportion 2| of the horn handle above referred to.
From the foregoing it will now be seen that there is herein provided an improved micrometer which accomplishes all the objects of this invention, and others, including many advantages of great practical utility and commercial importance.
As various embodiments may be made of this inventive concept, and as various modifications may be made in the embodiment hereinbefore shown and described, it is to be understood that all matter herein is to be interpreted merely as illustrative and not in a limiting sense.
I claim:

A horn micrometer comprising a longitudinally elongated body composed of a plurality of similar length gauge blocks arranged in end to end relation, an anvil block positioned at one end of said plurality of gauge blocks, a micrometer block of the same length as a gauge block, fixed rod means projecting longitudinally from said anvil block and extending longitudinally and slidably through bore means formed in said gauge blocks within their sides whereby said gauge blocks are confined on said rod means for individual sliding adjustment therealong, said micrometer block being formed with other bore means extending longitudinally through said micrometer block and slidably receiving said rod means, said other bore means in said micrometer block communicating with slot means in said micrometer block larger in diameter than said rod means and openingthrough a side of said micrometer block whereby said micrometer block can be removed from said rod means sidewise and selectively replaced on said rod means sidewise between any two adjacent gauge blocks or between said anvil block and a contiguous gauge block, clamping means on said rod means for engagement with a contiguous gauge block or said micrometer block to clamp said plurality of gauge blocks and said micrometer block together between said anvil block and said clamping means, and aligned horns on said anvil and micrometer blocks.
2. In a horn'micrometer, amicrometer block, an anvil block, and a plurality of gauge blocks arranged in end to end relation, said blocks being of substantially the same length and cross section, said gauge blocks being formed with a pair of longitudinal bores extending therethrough within their sides, a fixed pair of rods projecting longitudinally from said anvil block and having free ends, said rods extending slidably through the bores of said gauge blocks whereby said gau e blocks are confined on said rods for sliding adjustment therea'long:between'said anvil block and thedree ends of the rods, clam-ping means on-the freeend of at lea-stone ofsaicl-rods, said-micrometewblock being formedwith a' pairof longitudinal-slots exvtending longitudinally theretluough and commu- -nicating with the bores in and opening through-a side of said micrometer block, said slots being wider than said rods and enabling sidewise removal ot said micrometer block from said rods and selecgageable withan adjacent bloek to. compress said F blocks together between said cl amping: means and said-anvil block, and aligned horns on said anvil and micrometerblocks.
.3. I-n a horn micrometer,v an anvil-block, a micrometer block; and aplurality of gauge-blocks,
