UNITED STATES PATENT OFFICE.
OLIVER HUFNAGLE, OF DAYTON, OHIO, ASSIGNOR TO THE DAYTON. PUMP & MANU- 'FACTUBING COMPANY, OF DAYTON,.OHIO. I I
run? on THE LIKE.
Application filed July 14, 1926. Serial No. 122,337.
This invention relates to im rovements in pumps, or the like, being a eature of the pump set forth inmy copending application for patent Serial #102,574 filed April 16,
In the accompanying drawings which serve to'illustrate the invention: Fig. 1 is a view in side elevation, partly in section, of'a pump illustrating an application of the invention;
Fig. 2 is an end elevation; Fig. 3 is an enlarged detail view of Fig. 1. The particular novelty of the invention, as herein set forth, consists in means applied on the piston rod of the pump to prevent moisture following the rod from the water chest through the stuffing boxes into the crank case and thus act to prevent normal action of the oil in the crank case to main tain efiective lubrication of the mechanism.
Various devices are commonly used which are more or. less efl'ective for this purpose but failing in one particular or another to be in all respects satisfactory. After long expe 'ence and some experimentation, I have foun a very simple and fully efl'ective remedy for this trouble which is briefly described as follows A disc 1, as here shown, is fitted snugly on the piston rod 2 between the stufling boxes '34. The disc may be made of any suitable material, as leather, fiber, rubber, or metaland may be either fixed on the iston rod, if the clearance'between the st g boxes is sufficient to accommodate the stroke of the piston, or mounted slidably on the rod to compensate for the excess movement if the stroke of the piston is greater than the distance between the stufling boxes. In either arrangement the disc is tight fitting on the 40 rod to prevent seepage of moisture through the disc aperture and thence to the crank case.
With the disc disposed on the piston rod as shown in the drawings moisture following the rod from the Water chest by capillary action or more pronounced leakage will be diverted from the rod by the disc 1, the moisture moving over the face of the disc and dripping from its edge into the water pan 5, thus preventing any water following. the piston rod into the crank case.
,While the disc is here shown circular, it will be obvious that the circular form is not essential to its function.
The simple, inexpensive nature of the remedy for a very common trouble with water pumps of the character herein illustrated, and similar constructions, together with its entire effectiveness, give the invention value and importance quite out of proportion to its structural form.
Having described my invention, I claim:
A pump comprising a cylinder, a piston operable in the cylinder, a crank-case actue5 ating mechanism for the piston, and a flexible member arranged telescopically and slidably on the piston rod between the cylinder and crank-case acting to prrevent moisture following the piston rod om the cyl- 7o inder into the era '-case so arranged that the drip from the rod will take place between the crank case and the cylinder.
In testimony whereof, I aflix my signature.
