An Improved Machine for Beating and Brushing Carpets in Place.
We, CHARLES SCHWARTZENBURG CHAFFEE of Derby Avenue, Birmingham,
New Haven County, Connectient, U.S.A., Machinist, ALVIN STONE HOFFMAN
of Olivin Street in the same place, Mechanic, and FRANK ARTHUR GREEN of
Hill Street in the same place, Mechanic, do hereby declare the nature of this
invention to be as follows:-
In the carpet beating machine of this invention the mechanism is located in a
casing. It comprises a beater shaft to which are attached sheet metal beaters at
equal distances apart. The beater shaft is intermittently actuated from a star or
cam wheel on the driving shaft of the machine. The driving shaft carries at each
end a belt pulley from which pullies is driven a shaft provided with a circular
brush which extends across and behind the beaters and brushes the carpet as it
leaves the latter. Behind the brush the casing is provided with a dust receptacle.
The rigid arm through which the beater shaft is operated from the star or cam
wheel extends over the driving shaft and at its rearward extremity is provided with
a hinged operating finger which takes against the teeth of the wheel by its lower
face to operate the beater shaft but when the machine is drawn over the carpet
in the opposite direction the finger will turn on its hinge and permit the wheel or
cam to revolve without actuating the beaters.

COMPLETE SPECIFICATION.
An Improved Machine for Beating and Brushing Carpets in Place.
We, CHARLES SCHWARTZENBURG CHAFFEE of Derby Avenue Birmingham,
New Haven County, Connecticut, U.S.A., Machinist, ALVIN STONE HOFFMAN
of Olivia Street in the same place Mechanic, and FRANK ARTHUR GREEN of
Hill Street in the same place, Mechanic, 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 aud by the following statement :-
In the drawing
Fig. 1 is a plan, with the cover removed, of the machine of this invention.
Fig. 2 a section on line a-b of Fig. 1 but with the two part hinged cover
shewn.
Figs. 3, 4, 5, 6, are details on an enlarged scale.
A is a box or case to which a handle may be attached. Within the extreme
forward end of said box at its lower corners is journalled a beater shaft B to which
are attached a series of heaters B' located at equal distances apart, extending
rearward and each consisting of a thin strip of flexible sheet metal.
A rigid
operating arm C is firmly secured to the beater shaft B at the middle of the
length of this latter and extends over and to the rear of a driving shaft D carried

page_text: in bearings and over the beaters B'. The operating arm C is provided at its extreme
rear with a pivotal or hinged operating finger C' which is engaged by teeth D' formed
upon the driving shaft D. The finger C'is so constructed and arranged that when
the teeth D are engaged with its lower face in the forward movement of the
machine it will not yield but force the teeth to lift the arm C and rock the beater
shaft. When, on the other hand, the machine is moved backwards and the
leeth D engage with the upper face of the finger C, this will turn on its hinge
and permit the teeth to pass so that then the heaters are not actunted. The
finger Cis, as more clearly shewn in Fig. 3, pirotted to the under face of the plate
or head located at the outer end of the operating arm G so that said head resists
the upward movement of the finger. A spring fastened to the under face of
head e engages with the muder ince of the finger and normally holds it in place but
yields to permit it to be displaced, as shewn by dotted lines in Fig. 2, when the
teeth D of the driving shaft are brought into engagement with its upper face.
The operating arm C is formed with a long slot or clearance space through
which the teeth D pass for engagement with the pivotal finger. A spring E
secured to the front of the box or case A engages the upper edge of the arm C and
furnishes the power for snapping the beaters against the carpet after being lifted
therefrom by the engagement of the teeth D with the under face of the pivotal
finger carried by the operating arm. d are circumferentially recessed driving wheels
on the driving shaft projecting sufficiently below the box to support it just above
the carpet. Fare driving belts.
The brush is located at the back of the driving shaft being carried suspended in
two bars or arms H the forward ends of which are hung upon the ends of the
driving shaft (Fig. 5). The brush is composed of a shaft I having at its ends
metal rings radially recessed to receive the ends of holders K each formed of a
double metal strip or two strips between which strips 1 of felt are clamped. are
staples for additionally securing the holders radially around the shaft 1.
Mare the brush driving wheels in connection through the belts F with the
wheels and like these recessed at their peripheries so that the belts come well
within the wheels.
N is a dust receptacle extending somewhat underneath the brush so that when
the machine is lifted from the floor the brush is prevented from falling down.
It will be seen that the beaters heat direct into the brush and the heating is
done at about the middle of the machine further by journalling the brush in the
outer ends of pivotal arms or bars free to move up and down on their pivots (the
ends of the shaft D) it rests upon the floor by a pressure represented by its weight
and not in a fixed position with relation to the floor.
We are aware that it is not new to journal a rotary brush in arms pivotally mounted
within the case of a carpet beater and also that it is not new to employ a brush with
radially arranged holders for bristles and we do not claim either of those constructions
broadly.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what
we claim is :-
1. In a carpet beating and brushing machine of the kind referred to, the
combination with the case thereof, of a beater shaft located in the forward end of
said case, beaters attached to said shaft and extending rearward therefrom, a brush
located adjacent to the rear ends of the beaters, a driving shaft located between the
brush and the beater shaft, and connection between the driving shaft and the
beater shaft whereby the latter is actuated, and connection between the driving
shaft and the bruel whereby this latter is rotated, substantially as described and
shewn.
2 In a carpet beating and brushing machine of the kind referred to, the
combination with the case thereof of a beater shaft located in the forward end of
said case, heaters attached to said shaft and extending rearward therefrom, a

page_text: brush located adjacent to the rear ends of the beaters, a driving shaft located above
the beaters and between the brush and the beater shaft, an operating arm rigidly
connected to the beater shaft, teeth or lugs located upon the driving shaft and
engaging with said arm to oscillate the beater shaft, and connection between the
driving shaft and the brush whereby the latter is rotated, substantially as described
and shewn.
3. In the carpet beating and brushing machine described the combination with
the other parts of the same of the brush of the construction described and
shewn.
4. The general construction, arrangement, and combination of parts constituting
the carpet beating and brushing machine, substantially as described and shewn.
Dated this 23rd day of March 1895.
