Patented Jan. 23, 1906.

Application filed June 6, 1905. Serial No. 264,028.

To all whom, if may concern.-

1 3e it known that I, BERT H. THOMAS, a citizen of the United States, residin at Millers Station, in the county of'Cr'a ord and 5 State of Pennsylvania, have invented anew j and useful Milk-Aerator; andI do herebyd'e-A claro the following to be a full, clear, and exact description of the invention, suchas vwill enable ot 'ap ertai'ns to make and use the same. e invention ,relates to -an aerator, and has for its object to provide a device of this character which is exceedingl Simple, durable, and inexpensive and whic may be read- 1 5 the purpose of forcing air therein. for the purpose of purifying the milk. A. y, A further obJect is to provide a device which has-means for connecting a thermome- With these 'and other objects in fview the invention consisf in the construction and novel arrangement of arts vhereinafter described and.shown, an particularly 'pointed out in the appendedclaims. w

v In the drawings forming part of this specip cation,and in. which'likenumerals of refen. 1 ence designate corresponding parts, Figure 1 3o isa sectional view throu h a milk-can, show-A ing my device attached tV creto by means of a s Fig. 2 is a 'vertical `sectional. view.

l?P 3 is a detail sectional view on the line 3 3 of 2. f Fig. L isa plan view of the revolv4 35 ing ,'ollarcarrying means;- for attaching the devicetomilk-cans. y

, .Referring to the'drawings, 1v designates an n ordinary milk-can having a .pairof cylinders attached thereto -by means ofl a collar 3,

-4o adapted-to rotate on said cylinders and havers skilled in the art to which ity -ilyattachedor detached roma milk-can for,

ter with the pipeor tube extending into the'.

resilient arm 5, which is adapted to engage and disengage the milk-can when the work of 5o operating on a number of cans rapidi is de- Sired, as will be readily understood? The arm 5a .holds the device in engagement with the milk-can by spring-pressure.

The cylinder 3 1s provided with a'screwthreaded top, as at 9, and is adapted to re ceive a plun er-stem 11, provided with a pissus . ton 12, whic may be provided with an ordi-v nary check-valve, if desired, for the purpose of allowing a eat quantity of air to enter the piston as tfefsame travels upward.

.In the lowerpart of the cylinder 3, upon the circumference of the same, 1s acheck-valvel, which admits air as the piston travels upward and closes as the sameis pressed downward, .in which case air will pass through a suitable 'oipening from cylinder '3 into c linder 2, ,t ence upward and into a lateral y'projectv `ing-pipe'l,` and thence downward through a -vertlcally-dis osed tube 16, which projects into the mil can, as clearly shown. The .lower end ofthe pipe or tube lis rovided with erforations or apertures 17, w 'ch per-4 mit t e vair to s ray out at or near the bottom of the milk, w ch thereby puriiies the milk. 7 5

v.The vertical tube 16 is provided with a dovetail groove 18, which 1s designed as a suitable way in whicha thermometer can slide up or. down, according to the desire of the operator.- The lunger-stem is providedwith a suitable handle 20. I, desire it'to be understood that chan es in thepform, proportion, and minor detalls of construction maybe resorted to without departing from the spirit of myinvention or, sacricin any of the advantages thereof.

. What 'claim is-.-

1. In a device of the class described, the combination of a pair vor' tubes formed integral with each other, a coilar adapted to rotate 9c on said tubes, said collar being provided with' means for attaching the device to a milk-can, one of said tubes having alateral projection connected with a verticallydisposed tube, and means for forcing substantially as described.
