SUCTION CLEANING APPARATUS.

. Specification of Letters-Patent. l Patented Dec, 28, 1909,

pplcation filed April l, 1909. Serial No, 487,211.

To all whom it may concer/n:

Be it known that l, Gnoiicis Ron'nn'r Bruit, citizen of the Republic of France, residing at Paris, in France, have invented new and useful Improvements in or Relating to Suction Cleaning Apparatus, of which the following is a specification.

This invention relates to suction cleaning apparatus and has for its object to improve. and simplify thepunip actuating mechanism o't apparatus of the manually operated type of domestic apparatus used for vacuum cleaning.

According'to this invention thel reciprocating movement of the suction nozzle and vits pipe is utilized to operate the pump to which the nozzle is suitably connected` so that the nozzle or its pipe` can be held in both hands and a" better result be obtained with less fatigue, more particularly where the suction nozzle is provided with a brush on which some pressure has to be exerted and consequently Where -a certain resistance has to be overcome.

In the accompanying drawings which show three constructions of apparatus according to this invention, Figure 1 is a diagrannnatic sectional elevationof a suction cleaning apparatus. Fig. 2 is a'bross-section thereof, and Figs. 3 and 4f. show modi` lied constructions of 'a part of the suction device.

The body 1 of the apparatus is provided in its lower portion with a filtering chamber 2 which separates the air from the dust, and the body or casing is mounted on a foot or stirrup 3 which enables the apparatus to be held in position by the foot of the operator. In the upper portion of the casing is arranged a cylinder 4 in which work two pistons andl connected together by a rod T. The ends of the cylinder e are piiovided respectively with suction valves S and 9 and discharge valves 10 and ll. 'llie rod 'T is provided with transverse projections 12 or trnnnions Which engage the forked end of a lever 13 pivoted to a pin 1% secured to the upper portion. of thel body 1 of the apparatus. A pipe section 15 is secured to the lever 13 and connected at its lower end by means of a flexible tube 1G to the union 17 of the filtering chamber Q. The upper end of the pipe 15 is connected by a flexible tube 18 to one end of the pipe 19 on the other end of Which is mounted the suction nozzle. The pipe -19 is secured to a lever 20 conl nected by means/of a ball and' socket joint l Q1 to an arm 2Q secured to or formed 1n one with the lever 13, and connectedwith the pipe 1Q.

It will be understood that owing to the method of connecting the pipe 19 tothe other rigid pipe 15, the suction nozzle canv be inclined in a suitable maiinei' to reach the articles to be cleaned, and that by imparting to the pipe 19 and consequently to the suction nozzle which it carries, a recipro-l cating movement, this movement is iinparted to the pistons 5 and 6 through the levers Q0' and 22. Suction is therefore produced alternatively at each of the ends of the cylinder 4: and consequently a practically continuons suction through the pipes 19, 18, 15, 1G, andpiltering chamber 2. A single reciprocating' movement being thus required for carrying `the suction nozzle over the articles to be cleaned and for operating the double-acting pump, the result is that the operator can put'both his hands on the pipe 19, and so Work the apparatus in a very convenient manner and with little fatigue.

In the cases Where :it is only necessary to employ one hand to work the apparatus the upper end of the lever 13 may be eX- tended to form a handle 23 (Fig. 3) in this case the flexible tube 18 and the nozzle pipe can be moved bythe other hand ofthe operator over the articles to be cleaned. The apparatus can also be arranged in such a -inanner that the pump is actuated either directly with vone hand only, or indirectly, both hands being applied to the -nozzle pipe 19. Such a construction is shown in Fi. l

-where the rigid arm 22 is provided with an operating handle 23, and the pipe 19 has pivoted to it a link 20 which can be turned about its pivot 24, and connected to the end of the arm 22. The apparatus can then be used in the manner described .in connection with Fig. 1v While, when the link 20 -is disconnected as shown in full lines in Fig. 4, the apparatus can be used as though con` structed in accordance with Fig. 3. `When the lilik 20- is folded back out of operation on tothe pipe 19, as shown in Fig. 4, it can be held in position thereon by means ot an elastic collar (not shown in the drawing) or clip of any convenient construction.

It will be appreciated that the reciprocating vpump may be of any construction, and that other. details. of Vconstruction may be varied, withinl the limitations of the claims,

2. The combination with a vacu um pump, of a nozzle, flexible means establishing com# munication between said nozzle and pump,

' and articulated mechanism' connecting vsaidnozzle with said pump andserving to operate the 'latter uponv movement of 'the former.

3. The'combination with a vacuum pump, of a nozzle, a pivotally mounted lever'connected with said pump, a pipe secured to said lever adjacent the pivotal mounting thereof, a flexible connection establishing communication between one end of said pipe and said pump, a iiexiblel connection establishing communication between the other end of said pipe and said nozzle, andvmechanism connecting the nozzle with said .lever and serving to operate the same and said pump, upon movement of said nozzle.

In testimony whereof I aIiX my signa-v ture in presence of two witnesses.
