1, ALFRED JULIUS BOULT, of 323, High Holborn, in the County of Middlesex,
Member of the Institution of Mechanical Engineers, do hereby declare the nature
of this invention to be as follows:-
This invention relates to revolving cards with intermittently driven tops and
predetermined intervals of rest between each stroke, the intermittent motion being
so timed that each individual movement produced at one stroke equals the width
of one card top. This intermittent motion being comparatively rapid enables the
formation of knots to be avoided and prevents the fibres from agglomerating.
This intermittent propelling method, therefore,-by avoiding the two drawbacks
just mentioned, greatly improves the condition and appearance of the material
when the card-top, in returning, rises and gets clear of the drum.
This, in the improved machine, is effected with sufficient speed to obtain the
results and avoid the inconveniences named; in addition the improved mechanism
offers the very important advantage of permitting the sharpening of the points or
teeth of the card-top to be performed by any suitable sharpening device during the
intervals of rest of the top. The shape of the sharpening device may for example
be more or less concentric with the periphery of the large or main drum, so that,
without altering the card-tops, a larger carding surface is provided than hitherto, or
in other words a larger surface is brought into partial contact with the main drum.
The construction of this device may, however, as before stated, vary to suit
circumstances, so long as the principle of the invention as above stated is
adhered to.

COMPLETE SPECIFICATION.
Improvements in Carding Engines.
A communication from EUGENE APPENZELLER and CHRETIEN LENTZ, both of
Alost, in the Kingdom of Belgium, and EMILE FILLEUL, of Hatten (Alsace),
in the German Empire, Manufacturers.
I, ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex,
Chartered Patent Agent, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement :-
This invention relates to improvements in revolving carding engines in which the
card tops are driven or moved and stopped at intervals, the forward motion being
so timed that each stroke corresponds with the width of a card top.
Figure 1 is a general front view of the mechanism for operating or moving the
card tops, and
Figures 2 to 4 are details thereof.
BBB represent the run or race for the card tops which in the usual manner
pass in the form of an endless chain over rollers.

page_text: The intermittent operation or moving of the card tops is effected by the following
means.
The main shaft of the carding engine Figure 1 is provided with a pulley W¹
serving as a medium for driving the pulley W on the shaft V from which the
movement is communicated to the spur wheel N¹ through the intermediate gear
wheels P and T on a shaft Q.
The spur wheel N¹ on shaft O, Figs. 2 and 3, is coupled to a wheel N which
latter is provided with teeth only over a certain portion of its periphery and two
recesses a and b one on each side of the teeth.
When the wheel N is rotated by the spur wheel N¹ the toothed portion or
segment of the wheel N approaches the pinion K and in engaging with it, causes
the latter to rotate until the last tooth of the wheel N has passed, which is
calculated so as to impart exactly one revolution of the pinion K.
After the last tooth of the wheel N has passed, the pinion K remains stationary
and is retained in its position either by friction or by means of a disc K¹ of a
peculiar form and adapted to engage at certain times with its two corners 6' and a¹
into the recesses and a without being an obstacle to the gearing of the pinion with
the wheel N.
It is therefore obvious that for each revolution of the wheel N the pinion K
makes a revolution although with the difference that the said pinion K remains
stationary during part of a revolution of the wheel N and then makes its revolution
at a rapid speed.
This intermittent motion of the pinion K is communicated through the medium
of an eccentric J, rod H and pawl R to the ratchet-wheel S and adjusted so as to
move the ratchet wheels by one tooth at each revolution of the pinion K.
The ratchet wheel S is secured on the same shaft as the pitch wheel S' for
driving the chain with the card tops and the arrangement is constructed in such a
manner that for each tooth on the ratchet wheel the chain is moved a piece equal
to one card top.
This intermittent motion being comparatively rapid prevents the formation of
knots and the agglomeration of fibres.
Instead of moving forward one cap or top only two of them may be moved
where the total number of caps or tops is odd, so that each will be sharpened single
whenever two revolutions have been completed by the chain; or more than two
caps or tops may be made to travel forward at the same time if it be deemed
advantageous.
This intermittent propelling method therefore-by avoiding the two drawbacks
just mentioned greatly improves the condition and appearance of the material
when the card-top, in returning, rises and gets clear of the drum.
This, in the improved machine, is effected with sufficient speed to obtain the
results and avoid the inconveniences named; in addition the improved mechanism
offers the very important advantage of permitting the sharpening of the points or
teeth of the card-top to be performed by any suitable sharpening device during the
intervals of rest of the top. The shape of the sharpening device may for example
be more or less concentric with the periphery of the large or main drum, so that,
without altering the card-tops, a larger carding surface is provided thau hitherto, or
in other words a larger surface is brought into partial contact with the main drum.
In order to effect the sharpening of the tops during the intervals of rest a cam L
keyed on the shaft M, Fig. 1 is made to act on a lever G pivotted at F, the second
arm G of the said lever G pressing against a roller D', of a slide D so as to raise
and allow of the lowering of the said slide D at each forward movement of the cap
.or top.
The slide D lifts also the sliding bearing d Fig. 4 of the sharpening drum A, the
latter being moreover allowed to make another movement at right angles to the
axial line of its up and down motion.
It is only necessary to describe the main points of the arrangement to enable a
mechanic to construct the support.

page_text: Figure 4 is a cross section of the slide D taken at right angles to its longitudinal
axis.
The sharpening drum A is driven by gear-wheels E and E¹ the former being
keyed on a shaft fixed to the slide C while the wheel E' is supported by the
shaft mounted in the slide d.
The slide D receiving its up and down motion through the lever G G₁ causes
also the slide d with the shaft and sharpening drum A to move up and down.
The rotation of the cam C preferably keyed or otherwise fixed to the hub of the
wheel E and rotating on the shaft causes a lateral movement of the slide d in the
direction of the movement of the caps or tops so that thereby during the moving
of the slide D the sharpening drum A is caused to move in a direction resulting
from the two combined movements (at right angles to each other) of the shaft i.
The combination of the two movements of the shaft i may be varied by changing
the gearing E and cam C", in such a manner that the sharpening drum A during
the intervals of rest makes a lateral movement, starting from the beginning of a
card top towards the end while at the same time it also makes a downward
movement so as to enable it to sharpen the card-top for any shape.
The most suitable shape to be adopted will be ascertained by experiment.
In order to obtain the exact form over the whole surface of each top and for
cach top, the card tops must always present the same parallel position to the
periphery of the sharpening drum. The special device adopted for this purpose is
intended to hold during the sharpening, the tops immediately in front and behind
the sharpening drum by means of an intermittently working clamp. This device
may be constructed in various ways. In the drawing we shew in Figure 1 a
clamping device working conjointly with the lever G F G¹ through adapting
a third arm G to the pivotting point F which arm G" is connected by a link G³
to a bell-crank lever G* G. The latter being at its free end bent and shaped in
such a manner as to press exactly against the lower surface of the card tops just at
the junction of two tops with the driving chain. The point of contact is near the
sharpening drum and the apparatus is arranged so as to press simultaneously at the
front and at the rear part of the tops and thus hold the top exactly parallel to
the axis of the sharpening drum.
The movement of the supporting arm G' is simultaneous with the up and down
movement of the sharpening drum and the intermittent movement of the tops and
depends on the movement of the cam L. But any other suitable movement or
device may be equally well adopted for that purpose.
Having now particularly described and ascertained the nature of the said inven-
tion, as communicated to me by my foreign correspondents, and in what manner
the same is to be performed, I declare that what I claim is ;-
1. An arrangement for intermittently operating the card tops in revolving card
engines by means of which all the tops are moved simultaneously the width of a
single top.
2. In conjunction with the intermittent movement of the tops characterized in
Claim 1, the device for sharpening the points or teeth of the card tops during the
interval of rest.
3. In conjunction with the intermittent movement of the card tops characterized
in Claim 1 the alternate supporting of the tops by means of adjustable rests for the
purpose of presenting the tops during the sharpening operation always in the same
position parallel to the axis of the sharpening drum without thereby preventing or
obstructing the forward movement of the tops.
