PUMP-CYLINDER.

SPECIFICATION forming part of Letters Patent No. 763,028, dated June 21, 1904. y Application filed September 19, 1902. Serial No. 124,068. (No model.)

To (LN, whom it may concern:

Be it known that I, RUDOLPH STONE, acitizen of the United States, residing' at Catawba, in the county of Price and State of Wisconsin, have invented.v a new and useful Pump-Cylinder, ofI which the following is a specification.

This invention relates to the cylinders of pumps and similar structures, and has for its `Object the production of detachable ends for the cylinder which may be readily attached to and detached from the cylinder and rotatively adjusted thereon independently of the cylinder and of the plunger or piston-head.

To thisend the invention consists in the details of construction, as hereinaftershown and described, and specified inthe claims.

In the drawings illustrative of the invention, Figure 1 is a side elevation, partially in section, of a pump-cylinder embodying the improvements; and Fig. 2 is a` plan view of various forms of pump-cylinders and may be applied to some forms of' steam-engines and similar structures, and I do not, therefore,

wish to be limited in any manner to the form of structure to which the invention lmay be applied. i

The improved device is more particularly applicable to pumps and other similar structures which are exposed to moisture, whereby rust gathers around the holding-bolts and renders the detachment of the parts a matter of extreme difficulty.

For the purpose of illustration the invention is shown applied toa pump-cylinder (indicated at 10) and provided with a plunger 11 and pump-rod 12 of the usual construction. The cylinder 1() is provided-at one or both ends with laterally-extended flanges 13 of comparatively greater length longitudinally of the cylinder than ordinary flanges,as shown. As the structure of both cylinder ends is substantially the same, like designating characters are employed to denote corresponding parts in each. The ends of the cylinder are indicated at 14 and are each provided with a depending peripheral flange or rim 15, closely engaging and rotative upon the periphery of the flange 13, the length of the depending flange or rim corresponding to the length of the' flange, as shown, so that a comparatively extensive contact area is provided between the cylinder i and cylinder ends. nall y disposed in the depending rims or flanges 15 at suitable interval-s are bolt-apertures 16, the apertures being continued through the cylinder en ds,as shown. Any required numberof th'ese'apertures may be employed, according to the size of the cylinder; but for the purpose of illustration four are shown spaced apart and opening .inwardly against the flanges 13. The holding-bolts are indicated at 17, passed between the flanges l13 and 15 and provided with laterally-extended heads 18 upon their inner ends, adapted to project into engagement with the outer surface of the flanges 13, as shown, and with nuts 19 upon their outer ends. By this simple arrangement it will be obvious the cover memberslll will be firmly secured in place upon the cylinder by the coaction of the laterally-extended heads 180i' the bolts and the flanges 13, while at the same time leaving the end members free to be rotatively adjusted upon the cylinder, as the heads 18 of the bolts will engage 'the lower edges of the flanges at all points of the circumference of the anges. By this means the end members may be rotatively adjusted upon the cylinder independently of the cylinder, pump-rod or plunger, which is a very desirable advantage under certain circumstances.

If the end members and their bolts after long exposure to moisture become rusted fast,

Longitudithey may be readily loosened by slightly reversing the nuts and applying a rotative force to the cover member to break it loose,l.which action will not inA any manner `inj uriously affect the pump-rod or plunger or other parts, as will be obvious. By this peculiar and IOO which action leaves the ends free to be moved longitudinally or rotatively, as may be found most convenient in loosening them previous to their removal. By this simple construction a cylinder end is produced which may be very readily connected to and disconnected from the cylinder and adjusted to any required extent and which will never become rusted fast to the cylinder to an extent suflicient to annoy the operator in his'eforts to remove them.

The device may be applied to pump-cylinders'of any size or capacity or to other similar structures. n

It will be noted that by this invention the cylinder ends may be connected to the cylinder at any point in their circumference and no attention need be paid to the relative rotative position of the parts, as the heads 18 of the bolts [it the flanges 13 at one point as well as another.

Another advantage to be noted is that the mechanism of the pump above the cylinder may be turned to any desired point independently of the cylinder or the cylinder adjusted rotatively to any desired extent independently of the` mechanism above the cylinder, which will on many occasions be a very desirable and useful advantage, especially when the pump or other structure and its operating mechanism are located in cramped quarters, as frequently occurs.

Another important advantage of the improved device is that the comparatively long bearing-surfaces between the end members and the cylinder irmly support the parts, so that lateral strains are borne entirely by the cylinder and the depending portions 15 of the ends and the bolts relieved from lateral strains.

The intake-pipe is indicated at 2O and the discharge-pipe fitting at 21, of the usual form; but it will be understood that the device may vbe employed in connection with any form of cylinder-pump or similar structure, and I do not wish to be limited in any manner in the employment of the improved device with any specic arrangement of the intake or outlet piping'or their connections.

ing a cylinder provided at each end with a laterally extending iange, cover members each having sides adapted to engage the periphery of the flange at one end and terminating flush with the lower surface of said ange, and separate securing means for said cover members, said securing means comprising bolts provided with squared heads arranged in suitable apertures in said cover members and having the heads engaging the flanges on the cylinder and contacting With the outer surface of the cylinder to prevent rotation of the bolts.

2. A device of the class described comprising a cylinder provided at each end with a laterally-extending flange, cover members for the ends of said cylinder each having sides adapted to engage the periphery of the flange at one end of the lcylinder and terminating flush with the margin of the iange remote from the end of the cylinder, and independent means for securing said cover members so thatthey may be independently rotated on said cylinder or removed therefrom, said means comprising bolts with square heads arranged in suitable apertures in said cover members and having the heads engaging the anges on the cylinder and lying in contact with the outer surface of the cylinder.

In testimony that I claim the foregoing as my own I have hereto aiixed my signature in the presence of two witnesses.
