Improvements in measuring go
I, EUGEN WEBER, at Pforzheim, in the Grand-Duchy of Baden, German
Empire, Manufacturer do hereby declare the nature of this invention, and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
This invention refers to measuring gauges of the kind in which one of two
parallel measuring legs is attached to a flat bar, and the other to a slide adapted to
be displaced along said bar. My improvements in measuring-gauges of said kind
relate to the means for securing the slide in position, and consist in letting the
guide-flanges of the slide, or suitable portions of said flanges, project over the rear
side of the flat bar, and in connecting said flanges, or portions, by a screw, or
screwed spindle and nut, in such a manner, that the flanges of the slide may be
drawn against, and pressed upon, the edge-surfaces of the flat bar so as thereby to
secure the slide with its leg in position. The purpose of said improvements is to
prevent said edge-surfaces from being injured by the fastening-screw, as is the case
in the measuring slide-gauges at present employed, and to provide a somewhat
extended pressing-surface not on one side or edge only, but on both of them.
In order to make my invention more clear, I refer to the accompanying drawing,
in which similar letters denote similar parts throughout the different views, and in
which:
Figure 1 is a side-view of my improved measuring slide-gauge, the movable
measuring leg being withdrawn from the stationary one;
Figure 2 shows the gauge seen from the righthand side of Figure 1;
Figure 3 is a rear-view of the slide, together with the medium portion of the
flat bar;
Figure 4 is a section taken on line 6-7 of Figure 3, &
Figure 5 shows a full view and an edge-view of a spring used in the gauge.
The slide a with its measuring leg a has the flanges b b that take, and project,
over the edges m' m² of the flat barm. The latter carries the stationary measuring
leg m and is provided with the usual scale or scales known with measuring
instruments of the kind in question.
The flanges b b of the slide a are connected by a screw or screwed spindle c
which passes behind the rear surface of the flat bar m. The screwed portion of
the spindle is provided with a nut n by means of which the flanges 6 b may be
moved one in the direction to the other, or may be pressed upon the edge
surfaces m' m² of the flat bar m respectively.
The screw or screwed spindle c serves also for holding a flat spring d the
particular configuration of which is best to be seen in Figure 5. The spring d is,
of course, situated between the screw c and the rear surface of the flat bar m, and
the curved medium portion of said spring takes around the inner side of the screw c,
whereas the straight legs of the said spring press upon the rear surface of the
bar m. Owing to this configuration and arrangement of the spring d the slide a
is, of course, pressed upon the flat bar m so that said slide is hindered from making
any undue movement. The action of the spring d is transmitted to the slide a by
the mediation of the screw c, and it is thus to be seen that the function of said
screw is a double one, in that it serves for holding not only the means for
automatically holding the slide in any position, but also the means for mechanically
6ixing it.

page_text: Having now particularly described and ascertained the nature of this inven
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. In a measuring slide gauge, the combination with the flat bar having the
stationary measuring leg, and with the slide having the movable measuring leg, of
projections extending from said slide over the edge-surfaces of said bar, and of
means for pressing said projections against said edge-surfaces, for the purpose as
described.
2. In a measuring slide-gauge, the combination with the flat bar having the
stationary measuring leg, and with the slide having the movable measuring leg,
of projections extending from said slide over the edge-surfaces of said bar, and
of a screw connecting said projections behind the rear surface of the said bar, and
adapted to press the said projections upon the said edge-surfaces of the flat bar,
for the purpose as described.
3. In a measuring slide gauge, the combination with the flat bar having the
stationary measuring leg, and with the slide having the movable measuring leg, of
projections extending from said slide over the edge-surfaces of said bar, and of
a screw connecting said projections behind the rear surface of the said bar, and
adapted to press the said projections upon the said edge-surfaces of the flat bar,
a flat spring situated between the rear-surface of the latter and said screw, said
spring being so bent as to be held and displaced by the screw,
for the purpose as
described.
Deted this 25th day of January 1897.
