Application filed November 13, 1909. Serial No. 527,924.

To altwhom it may concenf Be it known that I, JOSEPH H. TEMPLIN, a citizen ofthe United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Portable Vacuum-Pumps, .of which the following is aspecification.

My invention relates to portable vacuum pumps of various modified types adapted to be used for the well known method of vacuum cleaning. Heretofore vacuum pumps of this type were located in a distinct and separate or partitioned off chamber from the vacuum or dust separating compartment or chamber.

In my improved construction the vacuum chamber forms part of the pum construction there being no partition, ori ces, or air passages between the vacuum chamber and the pumping mechanism, the casing which covers'the' pump forms the only chamber or compartmentv which Wholly surrounds the mechanism of the pumps. The air-.as it is exhausted from the chamber causes an ih'- rush of air into the inlet and as thefree air rushes into the vacuum chamber it circulates freely around the pumping or exhausting mechanism andV the motors driving same, thereby cooling off same,before entering into .the pumping mechanism, through same The object therefore oflmy-.ijnvent-ionisto reduce' the number of parts and simplify same, cheapen` the cost of construction, reduce the weight, increase the eiiciency, and make a truly portable and noiseless machine of this character.

In the'accompanying drawings Figure f1 is a vertical section of my apparatus showing a double acting diaphragm pump used as an exhauster for producing a vacuum.

Fig. 2, -is a similar view .showing a double bellows. Fig. 3 is a similar view showing an exhaust fan. Fig.'4 is a similar view showin Eathree stage turbine.

Simi ar numerals of reference indicate like parts throughout the diere'nt views.

Referring to the drawings 1 is the main casing forming a vacuum. chamber 2, and completelysurrounding the pum ing devices. Gaskets 3 and 4 interpose between casing 1 and cover 5 also between casing 1 and base 6 clamped together respectively by vany well known clamping means form a hernietically sealed chamber 2. Base 6 forms a support for the pum ing mechanism and as shown in Figs. 1 an 2 is provided with an exhaust port 7 (used `for blowing purposes when desired) leading direct from the pump.

In Figs. 3 and 4 the exhaust isA taken through the side of the casing at 8 when the umping mechanisms are disposed assliown. Vhen they are inverted as in Figs. 1 and 2 the exhaust would be of course transmitted through the base at 7 as shown in Figs. 1 and 2. Cover 5 is provided with an outlet 9 into which the dust-laden air passesl through the well known medium of -suction hose and renovator, not shown.

10 is a dust separator supported within the vacuum cham er 2.

11 is an auxiliary separator or plate screen of fine material, said plate 11 1s disposed loosely on the support 12 incasing 1. It is easily removable and is optional whether same is used or not.

In Fig.y 2, I have shown a novel joint .whereby noise, friction and necessity of and support lubrication are eliminated. Connerting rod 13 is pivotally connected to crank pin 14, the opposite end of the connecting .rod is provided with a yoke'15, said yoke spanning lugs v16 freely and terminates angesl.

18 and 18 are another pair ofligs.on-' 'conffI necting plate`19. .e

Between lu s 16 and 18 is llmly clamped a resilient strip 20 of metal or rawhlde. Flanges 17 on yoke 15 are also firmly .clamped to said strip 20.

By the above device the upper end of the connecting rod can vibrate with the crank in and thel lower end can give accordmgly without frictionor lubrication and 1s noiseless. The operation ofthe mechanism is readily seen. The dust laden air passes into inlet 9 down throu h separator 10 which retains the dust therein through auxiliary screen 1'1v thence passing freely around the motorsl 21 cooling same, thence into the inlets 22 passing through the inlet and outlet valves respectivel and thence out of the exhaust port 23 into t e open air.

In the above system while I have shown my' preferred types I do not wish to limit myself to same or to the exact construction in all details of same, as numerous modifications of same can be made by those skilled in the art and still come within the scope of my invention, asinstead of a double .acting compressible vacuum producer, is-

tons may be employed, or instead of va ou; ble acting, a single acting mechanism may be employed or as stated before the turbine and fan mechanisms could be inverted or the double acting pump could be inverted from its present position and the purpose and operation still remain within one casing or vacuum chamber covering the whole mechanism, said mechanism all operating in'a vacuum element.

. Having thus described my invention what I claim as new and desire to secure by Letters Patent is 1. As an improved article of manufacture, a casing having a bottom or base, said base provided with an outlet, a cover for said casing provided with an inlet, said cover removably attached and scalable to said casing thereby forming a vacuum chamber, vacuum producing means secured to vsaid bottom or base, a motor operatively connected with said vacuum producing means, said motor and said vacuum producing means being located wholly within said vacuum chamber, and furthermore said vacuum producing means and said motor being wholly secured to said bottom. or base and having no contact whatsoever with the side-walls or top of said vacuum chamber, all in combination as and for the purpose set forth.

2. As an improved article of manufacture, a casing having a detachable cover and base forming a vacuum chamber, in combi nation withvacuum producing means, means for driving said vacuum producing means, said driving means and said vacuum vided with an outlet, vacuum pro ucing means secured tosaid base, a motor operatively connected to said vacuum producing means, said motor and said vacuum producing means being Wholly located within said vacuum chamber, all in combination as and for the purpose set forth.

4. As an improved article of manufacture, a casing having a bottom. or base, said base provided with an outlet, a detachable and scalable cover for said casing, said elements forming a vacuum chamber, said cover provided with an inlet adapted to receive a suction hose, vacuum producing means secured to said bottom or base, a motor operatively connected with said vacuum producing means, said motor and said vacuum pro? ducing means having no contact whatsoever -said vacuum producing means and the contact face of said bottom or base, to whlch contact face said vacuum producing means is secured, all in combination'as and for the purpose set forth.

5.' In a portable vacuum ump, a pumpchamber, a reciprocating dlsplacing member or piston located in or attached to said chamber, a pair of lugs disposed on the side of said displacing member or iston mechanism, a straight flexible mem er dis osed between said pairof lugs, one end o said member being secured to one of said lugs, the opposite end of said member being secured to the other lug, a crank-shaft rovided with :1 crank pin, a connecting rodJ pivotally connected at one end with said crank pin, the opposite end of said connecting rod adapted to be clamped to the middle portionrof said flexible member, said flexible member, said supporting lugs and said connecting rod being disposed longitudinally in line with each other in the direction of the travel of said displacing member, whereby a practically rigid connection longitudinally as well as a slight-flexibility or resilience transversely of said flexible member is attained all in com,

bination with means for driving said crankshaft as and for the purpose set forth.

6. In a portable vacuum pump, a pumpchamber, a reciprocating displacmg member or piston located in or attached to said pump chamber, driving lugs 1G and 18 disposed on the side of said displacingmember or piston mechanisima flexible member 2O disposed between said lugs 16 and 18, one end of said flexible member 2O being supported by lug 16, the opposite end of said member 20 being supportedby lug 18, a crank shaft provided with a crank-pin 14, a connecting rod 18 pivotally connected at one end With said crank pin 14, the opposite end 17 of said connecting rod 13 ada ted to be clamped to the middle portiono said flexible member 20, said flexible member 20, saidA lugs 16 and 18 and said connecting rod 13 being 'disposed longitudinally in l1ne with each other, in their respective positions, and in a line parallel 'with the direction or axis of the travel of said displacing member or piston, all in combination with means for driving said crank-shaft, as and for the purpose set forth.

In testimony whereof I atlix my signature in presence of two witnesses.
