Be it known that I, FLorn'G. Tnrr'nra citizen of the United States, residing at T'ro, county of Rensselaer',l State of New You 'have-'invented an Improvement in Pumps, of whichA the following description, inY connection with the accompanying drawing is'a specification, like characters on the representing like parts. v 1 lThisl invention relates to pumps and particularly to pumps such as are used for pump` ing up the ltires of automobiles. The objects ofthe invention are to providean improved pnpha'ving novel means for preventing an e'xiess oi oilfrom 'workingpast the piston; tof 'provide a'novel 'arrangement by which the piston filsr'gu'ided in' itsmovement, and otherwise to improve umps of this'naturc all as will be more gully hereinafter described. 1 f y fluorder to give an understanding'of my invention, Ihave illustrated'in thedra-wings a 'Selected embodiment thereof which will now be described, after which the novel features will pointed outiin the appended fin fheawingarig. 11S a ad@ View of' a um'p'e' odying my invention; v`
ig. 2 asectionon the line 2 2, Fig. 1.
"Thepul'npomprises a cylinder 1 in which operates fa 'piston 7 and which hasanair inletA Orf 2 which is controlled by an iny wrd y-pening" spring-pressedinlet valve 3, and also a discharge port 4 controlledv by an koutwardly-opening spring-pressed valve 5. '1`h,e outlet port 'fljcommunicates with a ni le 6 to which api'pe may be attached. he piston 7 is actuated from a driving Shaft 8 which extends into the crank casingl or eccentric casing 9i and which has fast thereon an eccentrlc 10 that is embraced by an eccentric strap 11, said eccentric strap being connected to the iston.
The parts thus far escribed are or may be all as usual in pumps of this nature.
In order that a pump of this type may operate properly, it is essential that the piston should be kept lubricated. but it is also highly important that no oil or other lubricant should work past the piston because the presence of oil in the air which is pumped into an automobile tire is detrimental to the tire.
In my present invention I provide a novel 1920. Serial N0. 353,333.
prevent any tenency for the latter to rock or twist in'thecylinder.
Situated between the cylinder -1 and the crank casing 9 is an intermediate member 12 which has integral therewith a partition or division wall 13 that extends across the cylinder, said partition or separating wall having a central opening 14 therein in which operates a piston lrod 15 which is rigid with the piston and pivotally connected with the lower end ofthe eccentric strap as shown at 16. 1 i f The intermediate member 12 forms a continuation of the walls yof the crank case chamber 9, and the partition 13 is shaped to present the annular horizontal portion 17, the vertical portion' 18 and the upper horizontal portion 19 that isprovided with the aperture 14. The Apiston 7 is cup-shaped and the partition 13vis so shaped that when the piston'is at the lower end of its stroke the vertical flange or cylindrical wall thereof occupies the spacebetween the vertical portion18 of the'partition and the wall of the cylinder. f 1 w c y The; crank casingA is provided with van opening 20 through which oil or: other lubricating materials may be introduced, said oil 'o erating to lubricate *the driving shaft 8 an f theeccentric strap 11.
The-partition'l acts as'an oil guard or oiltrdeilector and prevents the oil-from beii'igV thrown directly againstthe walls of the cylindery by the rotating motion of the eccentric.
21 is a collar fast on the piston rod 15 and of a size to fit the interior of the vertical portion'18 of the partition 13. This collar 21 is provided with one or more apertures 22 through which the oil will seep. This collar 21 assists in holding the piston rod in a true vertical postion and preventsany rocking or cramping of the piston as it reciprocates. In the operation of the device a sufficient quantity of oil will work through the apertures 22 to lubricate the contacting surface of the collar 21 and the vertical portion 18 of the partition.
The amount of oil which thus works through the apertures 22 will also be sufficient to lubricate the contacting surface between the piston rod 15 andthe wall of the a rianne-14` and suliicient oily-,will work t rough the a lubrication to t e piston. n n
While the amount of oil which is delivered to the cylinder walls is sutiicient to properly lubricate the piston it is so small that no excess oil can work past the piston and accumulate in the compression end of the cylinder. p Y
23 indicates a breather aperture in the cylinder to relieve compression between the piston and the partition 13 on the down stroke.
I claim:
1. In a pump, the combination with' a pump casinghaving a cylinder and a crank chamber, of a cup-shaped piston operating in thc' cylinder and having a piston rod rigid therewith, a driving shaft ournaledinv the crank chamber and to whic the pistonrod is connected, and a member situated between vide with an oil-delecting partition extending across the cylinder, the central portion of the artition being raised and having a shape to t within the piston when'the latter is at the lower end of its stroke, said raised portion having an aperture through which the piston rod extends.
2. VIn a pump, the combination with a casing comprising a cylinder and a crank casing, of a piston o ratin inl said cylinder,v
a piston rod rigi with t e piston, a driving shaft journaled in the crank casing and connected to the piston rod, a partition extending across the cylinder beneath the pis- 3. A tire pump comprisin a cylinder, a'
crank casing adapted to contain lubricant, an
rture 14 to give V,proper the cflinder and the crank chamber and preoperating shaft journalled in the crank casing and situated in the axial line ofthe cylinder, a piston in the cylinder having a piston rod, means connecting theV iston rod to the operating shaft,and a partition member between the lower end of the cylinder and the top ofthe crank case, said member having a raised central portion rovided with an opening `through which t e piston vrod extends, said member constituting means to prevent oil from being thrown against the walls of the c linder by the rotation of the operating shalyt.
V4:. A n improved automobile tire pump structure com rising an eccentric case containing a lu ricant, a cylinder mounted thereon, an operating shaft journalled in the crank case and situated in the axial line of the cylinder, a piston in the cylinder having a iston rod, means connecting the piston rod) to the operating shaft, and a separating wall between the lower end of the cylinder and the top of the eccentric case, said wall having a raised central portion plil'ovided with a bearing o nin through w 'cli the piston rod exten ang constituting means to revent oil from being thrown against the walls of the c linder by the rotation of the operating shart. v 5. In an automobile tire pump, the combination with an eccentric case containing a lubricant, of a cylinder mounted thereon, said cylinder having inlet and outlet valves in one end and a breather openingat the other end, a single stroke piston operating in the cylinder, a piston rodconnected to the piston, means connecting the piston rod to the operati shaft, and a separating wall between the ower end of the cylinder` and.
thetop of the crank case, lsaid wall having a bearing opening through which the piston rod extends and acting as a defiector to revent the oil which is splashed by the s aft from being thrown against the wall of t-hel cylinder. y In testimony whereof I have signed my name to this specification. v l FLOYD G.
