Tocll whom. ttmay concern:

Be it known that I, Cmnnns B. DALZEIL, a citizen of the United States, residing at Little Falls, in the county of Herkimer and State of New York, have invented a new and useful Improvement in Pneumatic Cleaning-Tools, ofwhich the following is cification. I his mvention relates to currycombs and other cleaning tools or implements in which an air current is employed for removing the hair, dirt or-loosened foreign -matter from the comb, tool or implement.

a simple and efficient tool of this character in which the hair, dirt or loose foreign matforeign matter from all parts of the tool,

reventing the clogging ofthe air passage y accumulations of foreign matter therein, and thoroughly cleaning the hide or other surface to which the tool is applied.

In the accompanying drawings, consisting of two sheets: Figure 1 is a front elevation of a currycomb and its connections embodying the invention. Fig. 2 is a longitudinal section of the same on line 22, Fig. 1. Fig. 3 is a transverse section thereof on line 38, Fig. 1. Fig. 4 is a fragmentary longitudinal section of the same, showing a modified form of connection between the comb and suction pipe. Figs. 5, 6 and 7 ore front elevations of combs of modified construction. Fig 8 is a longitudinal section of a cleaning tool in which the walls on the face of the tool are made of rubber or other flexible material, the section being taken on line 8-8, Fig. 10. Fig. 9 is an end eleva- Fig. 10 is a face view of wardly or forwardly projecting comb wall D which forms between 1ts convolutions an air passage way which is open at one end for the admission of the air and communicates at the other end through the opening a with the suction chamber .8 and pipe C C. The

comb wall D may be provided in itsedg:

with serrations or dull teeth d, or may otherwise so formed as to loosen the hair and dirt when the comb is applied to the hide of the animal. In this construction the back plate A is oblong in shape, having its suction opening (1 located at its middle. The object of this invention 15 to provide communicating at its inner end with the suction opening a. The suction chamber -B is secured to the back of the plate A around the openlng a and to the pipe C which is arranged in a plane parallel with the back plate, so that the pipe can'be conveniently used as a ,handle' for manipulating the comb. The two sections C and G of the suction pipe are preferably connected by a ball and socket joint F, which permits freedom of movement of the. comb in use. Any

other suitable connection can, however, be

used for connecting'the suction pipe with the back of the comb.

In Figs. l-3, the plate A, suction chamber B and pipe C are permanently secured together, while in Fig. 1,-a modified construction is shown in which the suction chamber is permanently secured to'the pipe C, and the comb is detachably secured to said cham her by a bolt 71. which passes through the rear wall of the suction chamber and en gages a screw-threaded opening in a lug I on the back plate A. A packing K is placed between the edge of the suction chamber and the back plate A for forming an air tight joint between the parts. The comb can thus be readily attached to and detached from the suction pipe when desired and can be renewed when worn out.

In Figs. 5, 6 and 7 are shown combs of modified constructionin which the walls and the face of the comb, having its inlet opening in at one end and communicating at the other end with the suction device through the opening a which is located at the closed end of the passage. .In Fig. 6 the comb walls N are similarly arrangedv but the passage way it is open at both ends 0 and the suction opening a is located in the passage way intermediate of its ends, so that the air is drawn into the passage way at *both ends thereof. In Fig. 7 the comb is of star shape, the walls P forming a passage way about the outer portion of the plate A, which passa e way has an opening 9 at one end for the a mission of the air and communicates at its other end With a central pocket 1* formed by the inner wall of the passage wa and having the suction opening a locate centrally therein.

When the comb is placed upon the hide of the animal, the open or face side of the air passage way formed between the comb walls is practically closed by the hair and hide of the animal, and air can only enter the passage way through the opening in its end at the outer edge of the comb. The air current so entering this passage way is confined therein between the comb walls and follows these wallsand passes out through the suction openipg at the inner end of the passage way. By admitting the air to the passage way through a relatively large and practically unobstructed opening at the end thereof and confining it between the comb walls, a strong and steady air current is produced which travels swiftly through the passage way and comes into contact in its course with all parts of, the comb and removes all dirt and other foreign matter which are loosened by the movement of the comb or the action of the air current in passing over the hide. Although c nsiderable suction can in'this manner be/applied to the comb, it causes no discomfort o the] animal by drawing the hide too firmly against the comb, or otherwise, and it does not interfere with the free movement of the comb' over the hide. The passage between the walls is of such size and the current of air of suchstrength that there is no danger of the passage becoming clogged by accumulations of matter therein.

The cleaning tool represented in Figs. 8-10 is provided on its face side with a convolute cleaning wall S having a plain edge or face and preferably formed of soft rubber. The outer end of this wall is tapered or otherwise shaped to form an air inlet 8 for the convolute air passage t which communicates at its inner end with the suction opening a. The cleaning wall S is preferably formed integrally witha back plate T opening adapted to communicate with a suc-' tion device, substantially as set forth.

2. A pneumatic cleaning tool comprising a plate having a suction opening therein, and walls arranged on the face of said plate and forming thereon an air passage which is open at one end and communicates at its opposite end with said suction opening, substantially as set forth. p

3. A pneumatic cleaning tool comprising a plate having a suction opening therein,

The latter is provided a and walls arranged on the face of said plate I and forming thereon an air passage which extends over said face and has at one end an air inlet arranged at the outer edgeof said plate, said passage communicating at its opposite end with said suction opening, substantially as set forth.

4. A pneumatic cleaningtool provided on its face side with a convolute wall forming between its convolutions an air passage having at one end an air inlet and adaptedto communicate at its opposite end with a sac:

tion device, substantlally as set forth. 4

5. The combination of a pneumatic clean ing tool provided in itsback with a suction opening and having on its face an air passage which isopen at one end and communicates with said opening, of a suction chamber which is open at its front, and means for detachably securing said tool to said suction chamber, substantially as set forth.

6. The combinatipn of a pneumatic cleaning tool provided in its back with a suction opening and having on its face an air passage which is open at one end and communicates with said opening, of a suction chamber which is open at its front and'bears against the back of said comb, and a removable fastening device connecting said suction chamber with said tool, substantially as set forth.
