CARPET-CLEAN ER.

SPECIFICATION forming part of Letters Patent No. 744,721, dated November 24:, 1903. Application filed March 14, 1903. Serial No. 147,809. (No model.)

To ctZZ whom it may concern/:-

Be it known that I, GEORGE A. COWGILL, a citizen of the United States, residing at of Ohio, have invented a new and us'eful'Oarpet-Gleaner, of which the followingis a specification.

My invention relates to carpet-cleauers,and is an improvement on my carpet-cleaner patented June 18, 1901, No. 676,460,and the cleaning devices for which patent was applied for July 13, 1901, Serial No. 68,209, and April 24,

1902, Serial No. 104,483.

The object of the present improvement is to provide improved means for actuating the heaters, for conducting the air-blast toand beneath the carpet, and for preventing injury to the carpet by the heaters.

The invention consists in a fan-casing of peculiar construction, the'carpet being cleaned forming a portion of the front wall of the fancasing, heaters arranged in an enlargement of the casing, the air-blast passing downward between the heaters and thence under and beyond the carpet being cleaned; also, in the means for actuating said heaters and means for limiting the motion of the heaters, as hereinafter described and claimed. p

In the accompanying drawings, Figure l is a side elevation of that portion of my device containing the improvements herein described. Fig. 2'is a plan view, a portion of the fan-casingbeing-broken away and in section. ing the interior of the chamber containing the heaters and means for preventing dust from escaping therefrom. Fig. 4 is a perspective detail view of a part of the beatershaft, one of the heaters, andattachments connected to the shaft. Fig. 5 is a detail perspective view showing the means employed to actuate the beater-shaft. Fig. 6 is a detail section, the spring-pressed roller and bracket being in elevation. Fig. 7 is a detail perspective view showing the stop-pin carried by the beater-shaft. Fig. 8 is an enlarged detail view illustrating the construction of the rocker-bar and showing the springs connected at one end to the-bar and at the opposite ends to the casing.

In carrying out my improvements I employ base-beams A, on which are mounted the verby the heaters.

Fig. 3 is a detail sectional view showcarry the carpet A to be cleaned, all of which r is fully described in the applications heretofore mentioned.

The fan-casing comprisesa cylindrical chamber B, arranged in the rear of the carpet to be cleaned. At its forward side this chamber communicates with an air-passage B, having forwardly-diverging side walls, the part B being at its forward end nearly the width of the carpet, the-carpet forming the front wall of the casing. Immediately below and having free communication with the passage B is the beating-chamber B closed by permanent walls at the rear and sides and closed in front by the carpet being acted on From the lower partof this chamber extends a casing B forming an air and dust passage beneath the carpet, and this passage opens into the dustchamber described in my former-applications for patent andnot forming a part of the present im- B, mounted on a shaft C and driven by belting 0, running to the pulley 0 Means are of Through the chamber B pass two parallel shafts D and D journaled in the frame A", as is the shaft C.

A belt E, running over pulleys E E drives a shaft E which carries a pulley E The shaft D carries pulleys D D and D and the shaft D carries a pulley D A belt E runs from the pulley E to the pulley D Suitable belts run from the pulleys D to D and D to the'pulley F, carried by the shaft F, on which is carried the roller actuating the carpet. A plurality of curved beaters G are arranged on the shaft D A compound-curved rocker-bar H is rigidly secured to the shaft D adjacent one end, and at each end of the rocker-bar is secured one end of a coil-spring H, the other end of thespring being secured to the side of the casing. The tendency of these springs is to throw the beaters against the carpet.- A stop-pin H is secured on the shaft D adjacent the rockercourse provided to su pply air to said chamber.

bar, and when the shaft D is rocked the pin contacts with a stop H having an inclined rubber face Hflwhich stop prevents the heaters from tearing through or injuring the carpet.

Between the rocker-bar and the heaters the upper part of the shaft D is cut out, forming a flat surface J, to which is pivoted a laterally-projecting bar J, normally held at right angles to the shaft D by a coiled spring J secured at one end to the bar and at the opposite end to the shaft D The shaft D is transversely recessed, and a knocker-har K is rigidly secured in the recess extending on each side of the shaft and at right angles thereto. This bar is reduced in width intermediate its ends, whereby the end portions K project laterally beyond the intermediate outer side portion of the bar. This bar is so arranged that as the shaft D revolves the projecting ends of the bar K will strike the upper surface of the bar J, forcing it downward, rocking the shaft D and drawing the heaters away from the carpet; but as soon as the end K passes out of reach of the bar J the springs H immediately throw the shaft D in the opposite direction and bring the heaters against the carpet, the pin striking the stop H The construction of the parts are such that it is obvious that the shaft D will be rocked twice for each revolution of theshaft D.

A lever L, carrying a pawl engaging a rackhar L, is located at one side of the frame A and a cable L carried over suitable pulleys, extends from this lever to the bar J. By throwing the lever rearward the bar is drawn to one side outof the path of the knocker-har.

The shaft D is journaled in a bracket A on the frame A and extends transversely just above the forward edge of the top of the passage B. This shaft carries a brush D which bears against the carpet and prevents the latter from rubbing against the edge of the casing and also prevents air from the fan escaping between the edge and the carpet. To prevent air and dust escaping into the space between the top of the passage B a roller M is arranged of a size sufficient to fill this space and is journaled in spring-pressed hearings M, by which means it is held against the carpet, so that no dust passes between the roller and the carpet, and it also serves to keep the carpet in contact with the actuating-roller F. The belt 0 is driven from any suitable source of power, and it will he noted that by means of the lever L motion of the rock-shaft D can he stopped without interference with any of the belts or stopping any of the remaining shafts. It will also he noted that the draft from the fan strikes the carpet just above the heaters and travels downward along the surface being beaten, thus carrying the dust away as rapidly as it is loosened from the carpet.

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

1. A device of the kind described comprising fan and beating chambers, a passage extending from the fan to the heating-chamber and opening downward into the latter, a rockshaft carrying heaters arranged in the heating-chamber, a dust-passage leading from the said chamber, means for passing a carpet in the path of said heaters, means for preventing air and dust from escaping between the carpet and the edges of the heating-chamber, a fan in the fan-chamber, and means for driv ing same.

2. A carpet-cleaning machine comprising a beating-chamber, a dust-conduit, leading forwardly from the lower portion of the heating-chamber, a spring-pressed roller above said conduit adapted to bear on the carpet and prevent dust escaping into the space between the carpet and conduit, means for heating said carpet, and means for passing an air-blast through said beating-chamber.

3. In a device of the kind described, a heating-chamber, heaters arranged therein,means for passing a carpet vertically before said heaters, means for directing an air blast against the carpet above the heaters, an air and dust discharge conduit leading from the heating-chamber below the heaters, said airhlast passing downward along the surface of the carpet between the heaters, and means for actuating the heaters.

4. The combination with a beatingchamher adapted to receive a carpet, a rock-shaft arranged therein, curved heaters on said shaft, spring-actuated means for throwing said heaters toward the carpet, a bar normally held at right angles to said shaft, a parallel revoluhle shaft, a knocker thereon adapted to engage the bar on the rock-shaft and draw the heaters away from the carpet, means for drawing the bar from the path of the knocker, and means for limiting forward movement of the heaters.
