We, CHARLES DE HEMPTINNE and FERDINAND DE HEMPTINNE both of Ghent
in the Kingdom of Belgium, do hereby declare the nature of this invention to be as
follows:-
The object of the present invention is to design an apparatus to remove dirt or
noil from the cards of carding machines by mechanical means instead of by hand as
heretofore.
This apparatus applies as well to flat fixed cards as to cards mounted on a drum or
cylinder.
A friction wheel is mounted so as to be turned by contact with the loose pulley on
the shaft of the main drum, which pulley for this purpose is somewhat increased in
width and flattened at the portion which is in contact with the friction pulley. The
latter carries on its shaft an eccentric to the band of which is fixed a bent lever which
receives a reciprocating movement thereby transmitting a rocking movement to a
crank the pin of which engages in a slot at the outer end of the lever. This crank
or lever is keyed on the spindle of a vibrating comb and thus communicates movement
to this comb so that this latter acts upon the clothing of the drum in the same
manner as the heretofore used hand cleaners.
On the shaft of the friction wheel is mounted a mitre wheel which by means of
another mitre wheel transmits its movement to a worm which gears with a worm
wheel on the shaft of the drum and turns the latter slowly during the cleaning
process.
A hand wheel is keyed on a vertical rod provided with a screw thread passing
through a support provided with the female screw and carrying the whole of the
friction mechanisu worm wheel and eccentric which are also attached to a cross bar
one end of which is pivotted. On the vertical screw threaded rod is keyed a mitre
wheel gearing with another nitre wheel and through a suitable arrangement of shafts
and bevel gearing the movement of the vertical rod is transmitted to two spur pinions
which gear with two toothed segments sliding in grooves and carrying a sliding panel

page_text: of the outer casing of the main drum. On one of the above mentioned shafts a spur
pinion is fixed which gears with a spur pinion' on the shaft of which is mounted
another spur pinion gearing with a vertical rack. To this rack is fixed a laterally
projecting pin which when the rack is lifted lifts the lever and disengages the latter
from the crank or lever of the comb.
The action of the apparatus is as follows:
During the operation of the carding machine the friction wheel is not in
contact with the loose pulley the bent lever is held up and supported by the pin of
the vertical rack, and the worm is completely disengaged from the worm wheel of
the drum.
When the cards are to be cleaned the drum is stopped by transferring the belt to
the loose pulley and the hand wheel with the screw threaded rod is then turned to the
right. By this movement the friction pulley comes into contact with the loose pulley
and at the same time the worm meshes with the worm wheel on the shaft of the drum
the sliding panel of the outer casing is opened the bent lever descends by its own
weight, the rack with its pin being lowered and the notch in the lever engages with
the crank or lever of the comb.
The loose pulley turns the friction wheel which by means of the worm slowly turns
the drum and by means of the eccentric reciprocating movement is communicated to
the bent lever and by this latter an oscillating movement to the cleaning comb. The
dirt and noil removed by the comb falls under the machine. When the drum has
completed one revolution which generally suffices for removing the dirt and noil the
hand wheel is turned back and thereby the friction wheel is removed from the loose
pulley and the worm disengaged from the worm wheel on the shaft of the drum
while the pin of the vertical rack lifts the bont lever and disengages it from the
crank or lever of the comb which latter falls back by its own weight. Lastly in
continuing to turn the hand wheel the sliding panel is closed by the toothed segments
and the belt may be passed back onto the fixed pulley to recommence the operation of
the carding machine.

page_text: We, CHARLES DE HEMPTINNE and FERDINAND DE HEMPTINNE both of Ghent, in the
Kingdom of Belgium, 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 :-
The object of the present invention is to design an apparatus to remove dirt or noil
from the cards of carding machines by mechanical means instead of by hand as
heretofore.
This apparatus applies as well to flat fixed cards as to cards mounted on a drum or
cylinder.
The annexed drawings represent Fig. 1, an elevation (side elevation) showing
the parts constituting the Invention, Fig. 2. is a plan view of same, Fig. 3. is a
part of front view of the mechanism, similar letters of reference being put on similar
parts.
A friction wheel A is mounted so as to be turned by contact with the loose pulley
on the shaft of the main drum, which pulley for this purpose is somewhat increased in
width and flattened at the portion which is in contact with the friction pulley. The
latter carries on its shaft an eccentric Cito the band of which is fixed a rod I which
receives a reciprocating movement thereby transmitting a rocking movement to a
crank H. the pin of which engages in a slot q at the outer end of the lever. This
crank or lever H is keyed on the spindle of a vibrating comb G and thus communicates
movement to this comb so that this latter acts upon the clothing of the drum in the
same manner as the heretofore used hand cleaners.
On the shaft of the friction wheel A is mounted a mitre wheel B which by
means of another mitre wheel F transmits its movement to a worm E which gears
with a worm wheel D on the shaft of the drum and turns the latter slowly during the
cleaning process.
A hand wheel J is keyed on a vertical screw threaded rod J¹ engaging in a nut
pivotally carried in a support K with extension K' through which passes a shaft which
carries the friction pulley A, the mitre wheels F. B. the eccentric C and the end of a
cross bar Zon which is journalled horizontally the worm E, the other end of the
cross bar being suitably pivoted at Z. The support K bears also an extension K
resting on a vertical screw that may be raised or lowered in order to set the support K
in its normal position. The vertical rod J¹ is suitably journalled in an arm K³ of a
frame so as to be prevented from moving vertically. On the vertical screw threaded
rod J is keyed a initre wheel L gearing with another mitre wheel M and through a
suitable arrangement of shafts and bevil gearing, see Figs. 1 to 3, the movement of
the vertical rod is transmitted to two spur pinions R. R. which gear with two toothed
segments Q sliding in grooves and carrying a sliding panel P of the outer casing of
the main drum. On one of the above mentioned shafts a spur pinion U is fixed
which gears with a spur pinion. V on the shaft of which is mounted another spur

page_text: pinion W gearing with a vertical rack X. To this rack is fixed a laterally projecting
pin Y which when the rack is lifted, lifts the eccentric rod I and disengages the latter
from the crank or lever of the comb G.
The action of the apparatus is as follows
'-
During the operation of the carding machine, the friction wheel A is not in
contact with the loose pulley the eccentric rod I is held up and supported by the
pin Y of the vertical rack, and the worm is completely disengaged from the worm
wheel of the drum.
When the cards are to be cleaned the drum is stopped by transferring the belt to
the loose pulley and the hand wheel with the screw threaded rod is then turned to
the right. By this movement the support K is raised consequently the friction
pulley A comes into contact with the loose pulley and at the same time the worm E
carried by cross bar Z meshes with the worm wheel D on the shaft of the drum, the
sliding panel P of the outer casing is opened, the eccentric rod I descends by its own
weight the rack X with its pin Y being lowered, and the notch 9 in the lever engages
with the crank or lever of the comb.
The loose pulley turns the friction wheel A which by means of the worm slowly
turns the drum and by means of the eccentric C reciprocating movement is
communicated to the eccentric rod I and by this latter an oscillating movement to the
cleaning comb G. The dirt and noil removed by the comb falls under the machine.
When the drum has completed one revolution which generally suffices for removing
the dirt and noil, the handwheel is turned back and thereby the friction wheel A is
removed from the loose pulley and the worm E disengaged from the worm wheel D
on the shaft of the drum while the pin of the vertical rack X lifts the eccentric rod I
and disengages it from the crank or lever of the comb which latter falls back by its
own weight. Lastly in continuing to turn the hand wheel the sliding panel P is
closed by the toothed segments and the belt may be passed back on to the fixed pulley
to recommence the operation of the carding machine.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is
1. In an apparatus such as described in which, the loose pulley of a card drum
imparts motion to a wheel such as A the combination with an eccentric and its rod.
