Hamburg, in the German Empire. "IMPROVEMENTS IN REGISTERING YARDS AND
REGISTERING RULES." (A cominunication from Wilhelm Holmström, of Westervick,
in the Kingdom of Swerlen.)
The purpose of this Invention is the application of counting and registering
arrangements of different construction to yard sticks and rules, by means of which
the number of units measured are registered upon a scale.
According to the construction of this apparatus either a rectilineal or a circular
scale may be employed, upon which a hand or pin moves, the number of the leaps
of the band or pin corresponding with and registering the number of units that
have been measured.
The mechanism is generally placed within the handle or near the handle of the
yard stick or 'rule, while the registering scale may be placed upon one of the outer
sides of the same at any convenient part, according to purpose, size, or application
of the instrument.

page_text: The construction and application of the mechanism with yard sticks is generally
as follows: At the handle end of the yard is placed a small lever, turning on a pin,
and projecting about an eighth of an inch from the yard. By the thumb of the
right hand the operator presses the cloth or material that has to be measured
against this lever, and measures one yard as usual. By the pressure of the thumb
exercised upon the lever the latter turns round the pin and brings the mechanism
in motion, in consequence of which the hand on the scale registers 1. - By
means of a spring the lever returns to its original position, and measuring
another yard, the lever is again turned by a new pressure of the thumb, and 2 is
registered, and so forth.
The registering scale may be rectilineal or circular, and according to either
arrangement the construction of the mechanisın placed inside the stick must be
modified.
The motion of the lever is by this mechanism transmitted to the registering
hand, which leaps forward upon the scale, the number of leaps corresponding with
the number of measured units.
When the scale is rectilineal the hand moves inside and along a slide of the stick ;
while, with a circular scale, either the hand turns on a vertical pin, or to the scale
itself may be imparted a revolving motion.
The registering hand is returned to zero by pressing down a release pin, in con-
sequence of which a spring of the mechanism returns the hand to the original
position

FRIEDRICH HERMANN FELIX ENGEL, Civil Engineer and Patent Agent, of
Hamburg, in the German Empire. "IMPROVEMENTS IN REGISTERING YARDS AND
REGISTERING RULES." A communication from Wilhelm Holmström, of Westervick,
in the Kingdom of Sweden.
The object of this Invention is the application of counting and registering
arrangements of different construction to "yard sticks” and rules, by means whereof
the number of units measured will be registered upon a scale.
According to the construction of my apparatus I either employ a rectilineal or a
circular scale, upon which a hand or pin moves; the number of leaps. .or movO-
ments of the hand or pin corresponding with and registering the number of units
that have been measured.
The mechanism is preferably placed within the handle or near to the handle of
the "yard stick" or rule, while the registering scale inay be placed or marked on one
of the outer sides at any convenient part of the same,.all according to purpose, size,
or application of the instrument.
The construction of my mechanism with yard sticks is as follows:-At the handle
end of the "yard stick "is placed a small lever, turning on a pin, and projecting about
an eighth of an inch froin the yard. By the thumb of the right hand the operator
presses the cloth or material that has to be measured against this lever and measures
one yard as usual. By the pressure of the thumb exercised on the lever, the same
turns on the pin and brings the mechanism in motion, in consequence of which the
hand on the scale registers "1." By means of a spring the lever returns to its
original position, and when measuring another yard the lever is again turned by a
renewed pressure of the thumb, and "2" is registered, and so on.
The registering scale may be rectilineal or circular, and according to either
arrangement the construction of the mechanism placed insido the stick or rule must
be modified.
The motion of the lever is by this mechanism transmitted to the registering
hand, which leaps or moves forward upon the scale, the number of leaps or move-
ments corresponding with the number of measured units.
When the scale is rectilineal the registering hand moves inside and along a slot
of the stick, whilst, with a circular scale, either the registering hand turns on a
vertical pin, or to the scale itself a revolving motion will be imparted.
The registering hand may be returned to zero by pressing down a release pin, in
consequence of which a spring acting upon the mechanism brings the registering
hand to its original position.
In the annexed Sheet of Drawings,―
Figs. 1 and 2 show the "yard stick" with a rectilineal registering scale; and Figs.
3, 4, and 5 are details of the mechanisın.
Figs. 6 and 7 show the construction of the mechanism furnished with a circular
revolving registering scale; while Figs. 8 and 9 show the mechanism with a fixed
circular registering scale.
In Figs. 1 to 5 A is the handle of the yard stick; a is the pressure lever turning
on pins 8. When the lever a is pressed down the arm m moves the ratchet bars i
for the length of one tooth, and the finger v moving in a slot of the stick, and
fastened to i, marks "1" on the registering scale C; t is a spring which keeps arm
m in connection with the ratchet bar i; and E is a pin connected to spring u, by
means of which m and i are brought out of connection for the purpose of returning
hand v to zero of scale C; k is a brass coverplate or ferule to strengthen the yard
stick, and also to carry or serve as bearings for the pins &

page_text: In the line x, x, the stick can be divided or separated into two parts after
removing the screws 7, 7.
The modifications shown in Figs. 6, 7, and 8, 9, are very similar in construction;
a are the pressure levers; and C, the registering scales.
With the construction shown in Figs. 6 and 7 the scale revolves upon prossure of
lever a in measuring, whilst Figs. 8 and 9 show a circular scale marked on the
stick, over which an index finger attached to the pinion of the serrated counting
wheel i works by depressing action of a and its mechanism.
Having now described the nature and particulars of the said Invention in such
wise that the same may be carried into practical effect, I claim,-
First. Registering yards or rules with rectilineal registering scales as herein
described, and as shown in Figs. 1, 2, 3, 4, and 5 of the accompanying Drawings.
And, Secondly. Registering yards or rules with circular, revolving, or fixed
scales, as herein described, and as shown in Figs. 6, 7, 8, and 9 of the accompanying
Drawings.

In witness whereof, I, the said Friedrich Hermann Felix Engel, have hereunto
set my hand and seal, this Twenty-second day of December, One thousand
eight hundred and seventy-eight.
