SPECIFICATION forming part of Letters Patents No. 724,441, olated April 7, 1903.

Application filed July 13, 1901 To all whom it may cancer-n:

Be it known that I, GEORGE A. COWGILL, a citizen of the United States, residi'ng at Euphemia, in the county of Preble and State of pet-Cleaner, of which the following is a specification.

This invention relates generally to carpetcleaners, and more particularly to an improved construction of cleaner which is an improvement upon the Patent N'o. 6763460, granted to me June 18, 1901. i

The object of the present invention is to provide a carpet-cleaner in which the carpet can be more quickly and easily cleaned than heretofore; and another object of the invention is to provide a carpet-cleaner in which wide or narrow strips of carpet can be cleaned with equal facility; and a still further object is to provide a carpet-cleaner in which the air-blast can be regulated according to the width of the'carpet strip to be cleaned; and a still further object is to provide a carpetcleaner in which the dust forced from the carpet can be quickly and easily carried off and gotten rid of.

Another object of the invention is to prowhile it is being cleaned; and with the various objects in View the invention consists in the peculiar Construction of the several parts and also in the novel manner of combining or arranging said parts, all of which will be fully described hereinafter and pointed out In the drawings forming part of this specification, Figure l is a perspective view of a carpet-cleaner constructed in accordance with: Fig. 2 is a top plan view of my invention. Fig. 3 is a sectional View on the line 3 3 of Fig. 2, a portion of the blower and beater being shown in elevation. Fig. 4 is a detail View showing a portion of the' beater. Fig. 5 is a detail view showing one of 'the carpet-fastening hooks in a positionready to have the carpet forced thereon.

In carrying out my invention I employ a the uprights B and C, and the horizontal beams or timbers D. A roller E is journaled in the upper ends of the uprights B and carries a pulley E' at each end, and passing over v belts in their proper parallel position.

Serial No. 68,209. (No model.)

said pulleys are the belts E which are driven by means of pulleys E mounted upon'the shaft E journaled at the ends of the beams D, said shaft E receiving its power from any suitable source. i -Rollers F are journaled between the upper and lower ends of the uprights O and also between the lower ends of the uprights B, and passing around these rollers E'and F are a series of endless belts G, connected by means of a series of transverse strips G' in order to hold the endless Each belt Gr has -a series of pointed hooks H pivoted thereto, said hooks being Secured to the belts by means of plates H' and H said plates having depressed portions H which receive the journal of the hook, and also a spring portion H which bears against the said journal of the hook and yieldingly holds by frictional contact the said shank or point in a horizontal position for the' purpose of attachin g the'carpet to the said hooks. After the carpet has been placed in position the hooks can be :turned down, with their points substantially parallel therewith, and the contact of the springs with the shanks of the hooks will cause them to-remain in'that position until they are forcibly'turned into a horizontal position for removing the carpet.

In Fig. 5 I have illustrated on'e'of these hooks held in position to have the carpet forced upon the point or slank thereof, and after the point has been forced through the carpet it is then turned down to the position indicated in Fig. 1, and it will be impossible for the carpet to work loose from the hooks while it is being cleaned. By means of the roller E, which is rotated by means of the belts E it will be understood that the endless belts will be moved around the rollers E and F,

IOO

chamber K, which is located between the horizontal beams D and contains a rotary fan K', which is operated by means of a series of belts from the shaft D The mouth K of the fan-chamber is arranged in close proximity to the flight, passing between the rollers F at the upper and lower ends of the uprights C. In order to hold the belts and carpet in proper positions opposite the mouth of the fan-chamber, I provide guide-rollers L and M, jonrnaled between the uprights C and above and below the mouth of the fan-chamber, the rollers L being arrauged upon the interior of the belt, while the roller M is arranged upon the exterior, and if necessary this roller M will be cut or grooved in order to prevent the points of the hooks coming in contact With the said rollers.

The beater is substantially the same as the beater shown and described in my prior patent already referred to and consists of the cross-bars N, one of which carries the fingers N'. These cross-bars N are connected to the arms O, which are pivoted to the brackets O' and operated by means of the pitman P, connected to the pulley P', receiving its power from the shaft E also. It will thus be' seen that as the carpet is carried around by means of the endless belt it is beaten by means of the beater and subjected to an air-blast from the fan. The dust is forced into a dust box or chamber Q, which is closed on all sides, except the side directly opposite the mouth of the fan-chamber. The top of the dust box or chamber is made somewhat tapering, and

a dust chute or spout Q' leads from the center of the said top. Air-inlet tubes Q extend down from the top of the dust box or chanber to a point adjacent to the bottom of the same for the purpose of creating draft and generating Currents, by means of which the dust is forced out through the spout or chute Q'.

By employing a series of endless belts G, I am enabled to clean wide or narrow strips of carpet, and in the device illustrated in Fig. 1 I am enabled to clean two strips of narrow carpet at the same time. In case, however, only one narrow strip is to be operated on I provide for the utilization of the entire blast of air by` providing valves R within the fanchamber, said valves being pivoted at their outer ends, as shown at R', their inner ends being connected to links R?, said links being connected to a lever R by means of which the valves are opened or closed, as required, the top of the fan-chamber being slotted, as shown at R to permit such adjustment. When a wide strip of carpet is to be cleaned,

the valves are thrown open to their full ex-` tent; but when a narrow strip is to be cleaned the valves are closed, thereby centering the entire blast of air at the point opposite the strip of carpet. 4 r

S indicates a roller detachably mounted upon the exterior of the uprights B, which roller serves to guide the carpet While being connected to the belts, and after the carpet has been cleaned it can be rolled upon this roller and removed from the cleaner. It will also be understood that the motion of the belts can he stopped at any time without stopping the motion of the beater and blower, a suitable clutch mechanism being employed to effect this result.

It will thus be seen that I provide an improved construction of carpet-cleaner which will effectively accomplish all of the objects heretofore mentioned.

Having thus fully described my invention, what Iclaim as new, and desire to secure by Letters Patent, is

1. Ina carpet-cleaner, au endless carpetcarrier comprising a series of parallel belts traveling on a plnrality of rollers, said belts being connected by means of a series of transverse strips, a plurality of pointed hooks pivoted to each belt, and a spring-plate hearing on the pivoted portion of each hook and adapted to yieldingly resist movement of the hook.

2. In a carpet-sweeper, a series of endless Vertical movable carpet-carriers arranged side by side, each provided with means for securing a piece of carpet thereto independently of the others, a blower-fan casing in front of the carriers, the mouth of which extends past 5 all of the carriers, means for direeting the blastfrom the casing to ei therside of a central point and means for simultaneously operating the fan and the canriers.

3. In acarpet-cleaner,the combination with a frame, a plurality of rollers mounted on said frame, endless belts traveling around said rollers, hooks attached to said belts and adapted to engage a carpet, a dust-box open at one end infthe lower part of the frame, a fanblower casing adjacent to and open opposite the opening in the dust-box and means for directing the air from said blower to either side of a central point.

4. In a carpet-cleaner, a dust box or chamber open at one side and having a discharge spont or chute extending from the top of said box or chamber, and the air-inlet tube extending from the top to a point adjacent to the bottom of the box or chamber, substantially IIO
