Improves the tool in 432,427 by altering the jaws to form a fuse splitting knife on one jaw and corresponding wedge on the other jaw. In the absence of markings or documentation, the existence of tools appearing to correspond to features of these patents is not proof of correlation. ATLAS POWDER CO. No. 3 is such a tool.

"In a fuse splitter, two pivoted plates are ranged side by side and provided with handle portions, one plate being provided with a notch having a splitting blade on one side and having a stop on its other side, and the other plate having a tubular guide one side a portion of which projects laterally from it into the said notch between the cutting blade and the stop and which is provided with a slot for the cutting blade to work in; said stop operating to limit the outward movement of the blade in the notch." Other features noted in the specifications (e.g. spring to return the handles to open position and cutters) are not part of the claims.

Semi-circular jaws with beveled edges to crimp blasting cap onto fuse, and sharp edges to cut the fuse. The patent was written up in the December 13, 1890 SCIENTIFIC AMERICAN SUPPLEMENT. German patent DE-68845 with effective date July 26, 1892 supplies Moodey's full name. The effective date of the German patent matches the date of Moodey's improvement patent 479,444, which added a "fuse splitter" function to the jaws. Given the variety of "fuse pliers" patented and produced, in the absence of definitive markings, one can speculate about matching patents to "generic" tools of similar design. ATLAS POWDER CO. NO. 3 is an example of a possible match.

Manufactured by L. S. Starrett Co. - Athol, Worcester County MA

This patent was used on the No. 221 Starrett micrometer. This patent was an improvement on patent #2,267,332. Abstract: The general object of the invention is to provide a micrometer gauge of the type stated having means for preventing lost motion at the motion multiplying lever, either in the gauge as first manufactured or after long use and possible wear of parts. Claim: In a micrometer gauge having a rotatable spindle and having first and second concentric sleeves partly surrounding the spindle and rotatable relatively thereto which second sleeve partly surrounds the first sleeve and has an outer end wall, a flange on the outer end of the first sleeve and provided with a notch and with a yieldable resilient portion at one edge of said notch, a transversely extending lever pivoted near one end to the spindle for movement about a longitudinal axis and serving to transmit rotation to a Limited extent from the second sleeve to the first sleeve :with the second sleeve rotating at a greater rate, said lever including a finger at the last said end thereof entered in the notch in said flange and having a width slightly greater than the initial width of the notch so that the resilient flange portion always applies pressure to the finger to prevent lost motion at type finger during pivotal movement of the lever and during relative rotation of the sleeves and said lever also including resilient bifurcations which define a lengthwise slot therein near the opposite end thereof, and a longitudinal pin on the end wall of the second sleeve entered in the slot in the lever and having a diameter slightly greater than the initial width of the slot so that the said resilient bifurcations always apply pressure to the pin to prevent lost motion at the pin during pivotal movement of the lever and during relative rotation of the sleeves.

Manufactured by L. S. Starrett Co. - Athol, Worcester County MA

This patent was improved by patent #2,741,847. This patent was used on the No. 221 Starrett micrometer. Abstract: My invention relates to that class of instruments for effecting delicate and accurate measurements, particularly as to depth and length or other dimensions of an article, and an object of the invention, among others, is the production of an instrument of the type herein mentioned, by means of which measurements to an extremely fine degree may be attained in a most accurate and expeditious manner. Claim: A micrometer gauge comprising a frame and including a threaded spindle, an anvil in cooperative relation with the spindle, a barrel in which the spindle is contained, a plurality of measuring sleeves rotatably mounted upon the barrel and upon one another, a connection between said sleeves for multiplying the rate of rotation of one relatively to another, a yielding connection between one of said sleeves and said spindle for operation of the latter, and means on said barrel and sleeves for denoting the amount of movement of said sleeves.
