To'all w/wm'z't may concern:
7 Be it known that I, JOHN J. MARKO, a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented new and useful Improvements in Pumps'for Pneumatic Carpet-Cleaners, of which the following is a specification.
This invention is an improved pneumatic carpet cleaner, the object of the invention being to provide an improved machine of this character which is extremely cheap and simple, is light, strong and durable, which can be readily manually operated with but very slight exertion on the part of the operator and which is not likely to get out of order.
The invention consists in the construction, combination and arrangement of devices hereinafterdescribed and claimed.
In the accompanying drawings, Figure 1 is a side elevation of a cleaner constructed in accordance with my invention. Fig. 2 is a vertical longitudinal central sectional view of the same. Fig. 3 is a vertical central transverse sectional view of the same. Figs. el5 are detail views.
In the embodiment of my invention I provide an upper bellows l and a lower bellows 2 which have a common connecting wall 3 between them, which forms the bottom of the upper bellows and the top of the lower bellows and is provided with a common discharge duct 4 for the bellows. The usual flap valves 56 are provided in said duct for the discharge openings of the upper and lower bellows respectively. The top 7 of the upper bellows has an intake opening and a flap valve 8 to control said opening and the bottom 9 of the lower bellows is provided with a similar intake opening and controlling flap valve 10 therefor. An exhaust nozzle 11 to operate immediately over the carpet is connected to the top of the upper bellows and a similar exhaust nozzle is connected to the bottom of the lower bellows, the said exhaust nozzles extending forwardly and downwardly from the machine as shown.
A handle 13 to enable the machine to be manually operated has its lower end secured in a socket let of a substantially V-shaped brace 15 which is secured to the under side of the bottom of the lower bellows, the handle extending rearwardly and upwardly from the machine.
. mon partition wall.
At opposite sides of the cleaner are combined wheel carriers and bellows holders '16 each of which has an upper fork 17 provided with upper inwardly extending arms 18 and alsohas a lower horizontallv v arranged portion l9 the ends of which provide inwardly extending lower arms 20. upper bellows is secured under and to the upper arms 18 of the carriersand holders and the bottom of the lower bellows is secured on and to the lower arms 20 of said carriers and holders. Said carriers and holders hence constitute frames which carry and secure the parts of the machine and also form guards for the operating and supporting wheels 21. These wheels are arranged on the inner sides of the carriers and holders and are mounted on stub axles 22 secured to the carriers and holders and which in practice are revolubly suitable bolts. Each wheelhas a crank pin 23 on its inner side which is also, in practice, revolubly a bolt. Connecting rods 24 have their lower ends pivotally connected to the crank pins 23 and their upper ends pivotally connected to pins which project outwardly from opposite sides of the common partition wall 3 of the upper and lower bellows, at points midway between the front and rear ends of said co Hence when the machine is pushed along on the floor the rotation of the wheels causes the connecting rods 24 to impart reciprocating vertical movement to the common partition wall 3 of the bellows, thereby simultaneously reversely operating the bellows so that one draws air inwardly through its exhaust nozzle and hence sucks in dirt from the floor or carpet while the other bellows discharges air and dirt therefrom through the duct l.
dirt receiving bag 26, which is made of suitablematerial, is detachably supported on the handle 13 as by means of a suitable hook 27 and has its mouth or neck, which is flexible, connected directly to the discharge end of the common discharge duct 4 of the upper and lower bellows as at 28 and is provided with a suitable stiifening frame 29 which is revolubly made of metal, is sewed in the mouth of the bag and screwed or otherwise secured to the rear end of the common partition wall of the upper and lower bellows, around the discharge end of the discharge duct thereof to efi'ect an air-tight joint at that point. The dust and dirt which are driven in the bag 26 are caught therein, the
The top of the air escaping through the meshes of the flap of the bag.
To increase the attractive efi'ect of the wheels each of them has its peripheries provided with a series of pivotally mounted said shoes having treads 31 on their lower sides made of rubber or other suitable material. These shoes are not only for increasing the attractive effect of the wheels but also serve to render the machine practically noiseless when in operation.
Having thus described my invention, I claim In a carpet cleaner of the class described I the combination of bellows provided with fixed top and bottom walls, carrier and Copies of this patent may be obtained for holder elements at their sides and having inwardly extending arms secured to the top and bottom walls, supporting and operating wheels mounted on the inner sides of the carrier and holder elements, and having cranks, a movable bellows element and connecting rods pivotally connected to the cranks of the wheels and to the said movable bellows element.
In testimony whereof I aflix my signature in presence of two witnesses.
