PORTABLE PNEUMATIC PUMPNG APPARATUS.
Application filed April i', 1910.
To ZZ l107mm 'it may Concern A lle it known that I, Howie SMALL, a citizen of the vUnited States, residingV at Atlantic itv. in the count)v of Atlantieaud State ol New Jersey, have invented Icertain new and useful improvements in Portable .llneuuiatie Pumping' AXpparatus. oi? which the following a specification.
My invention relates to improvements in a portable pneumatic pumping apIiara-us for el ailing earpets. draperies and the like.
The object oi luv invention is to construct a pneumatic pmnping apparatus in whieh the housingr or easingrs form a varuum chamber and a pnlsalion chamber and having a rihrating' member separatirn; said chambers, with means for operating said vibrating member togeiher with ysuitable valve mechanian. The said pulsaliou ehamber being made relati.el.v large to form a clearance space in addition to the 4space arually required for Jdie movements of the pumi'iing member.
A further object or' my invention to arranejethe said. chambers and the operating means in alinement with said vibrating member.
still vlurtl'ier objet-t of my invention is to provide double connecting rods between the .'ihratinfbr member and the operatingl means; and a still further object ol my inveniion is to Connect the said vibrating inember with the eonneeting rods so aste .limit the oscillating movement ot said vibrating member.
These together with various oher novel 'features of lconstruction and arrangements oli the parts eonstitute .my invention.
Referring' to the accompanying drawin fs, in which like relerenees refer to lilie paris: Figure l a vertical central section oi my improved pneumatii.` pumpingY apparatus; Fie: Q is a vertical sertion ou line 2-2 Fig. l lfio. 3 is a lxorizm'ital section on line 2%23 Fig. 2: and. Fig. l is a partial vertioal seelion of the sei-een, drawn on a larger scale. In the drawings .l represents the base whieh is eireular in form. having' a side wall 2 and a hottom portion Z5. Upon the top suriaee oi' the side vall :2 of the hase is a ring .7.. having: an upwardl) turned i'lange '6. which supports the hood S andL the sereeu l0. whirh are secured together at the top b v the holt l2, having a handle 13 by which Specification of Letters Patent.

the hood and the screen may be lifted oil" the base l.
The hood S has a, bottom section 1% which is adapted to encircle the base l and said hood also has a tlange 15 secured to the inner surface olf the same, which flange rests upon the rubber ring i6, which in turn rests upon secured to the base l. Thus making an air tight j uint between the hood S andthe hase.
"l" he said rubber ring lo is secured to and carried by the lower edge of the sereen 1G. The said ring 5, secured to the base l, has formed thereon arms 17, which extend upwardly and toward the Center of he ringl and terminate in the. base-plate 18, on which is/seeured the electric motor Q0, positioned in vertical alinement with the base i and the hood S, above described. Between the said ring and the side wall 2 of the base is clamped a liexible diaphragm 22, preferably iliade of leather. Said diaphragm has a eireulai' opening formed in the center thereof and the inner edge of said diaphragm 'is secured to the circular metal Coll-.ir 2, which latter and the diaphragm are referred to as a vibrating member. A clamping ring 24C secured to said collar 23, by screws or other suitable, means, securely holds the inner edge of said diaphragm to said Collar.
The follar has oppositely positioned supports 25 and 2G in which is mounted a shaft S27, rigidly secure-d in said supports by set-serews Q8 and i to the ends o1" he shaft 2T, by pins 32 and 83, and the opposite ends oi? said connecting rods embrace the eeeentrics 35 and secured upon each end of the shaft or ture'BT ol' the motor 20. `lli/hen the shaft 3? of the motor is rotated, 'the collar will vibrate rapidly. The two connecting rods will hold one axis of the collar pa allel with the. motor shaft 3T and the oscillating movement of the opposite axis of the collar will be limited by the eonneetion between the eoiiar and the connecting rods 30 and 3l, which prevents the-flexible diaphragm L2 from rereiving an unusual strain or from being worn in certain portions, due to the tiliiiin;- ot the follar rlhe eollar Q3 and the bottoni 3 of the base l are provided. in bhe Center thereof, with valves 4G and il respectively.
