OIL-PIPE ATTACHMENT.

Application filed August 26, 1922.

T 0 all whom it may concern:

Be it known that we, VERNON L. GinsoN and EDWARD G. I-IAJENGA, citizens of the United States, residing at Randolph, in the county of Cedar and State of Nebraska, have invented certain new and useful Iniprovements in Oil-Pipe Attachments; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to an attachment or device for use with the oil tube of an internal combustion engine, and aims to provide a novel and improved device of that kind which will facilitate the cleaning out of the oil tube, to save time and trouble.

It is the object of the invention to no vide an'attachment or device for use at the delivery end of the oil tube which enables access to be had to the delivery end of the tube, in a convenient manner, for cleaning out the tube, with a saving of time, labor and expense.

With the foregoing and other objects in view, which will be apparent as the description proceeds, the invention resides in the construction and arrangement of parts, as hereinafter described and claimed, it being understood that changes can be made within the scope of what is claimed, without departing from the spirit of the invention.

The invention is illustrated inthe accompanying drawing, wherein- Figure 1 is a side elevation of an internal combustion engine, portions broken away to illustrate the oil tube and attachment in elevation.

Fig. 2 is an enlarged plan view of the attachment with the parts thereof separated.

Fig. 3 is a longitudinal section of the de vice as installed.

Fig. is a cross section on the line 4:-4- of Fig. 3.

The attachment is intended for use in the internal combustion engine of a Ford automobile, in the crank case of which there is provided an inclined oil tube 7 having a funnel 8 at its rear end for receiving oil lifted by and dripping from the fly wheel, for carrying the oil to the forward end of the crank case and oil pan to flow rearwardly and fill the splash cups or receptacles, as Well known. The forward end of the tube Serial No. 534,569.

7 according to present practice, enters a in cleaning out the tube usually involves several hours time.

In carrying out the present invention, the tube 7 is cut off several inches from its forward end behind the partition or wall 9, and

the present attachment or device is used between the forward end of the tube and said partition. short tube 10 and the short tube 11 which are jointly slightly longer than the piece of the tube 7 which has been out off and re moved. The rear end of the tube 11 is soeketed, as at 12, for receiving the forward reduced end or nipple 13 of the sleeve 10. forming a shoulder l-t against which the rear end of the tube 11 abuts. The forward end of the tube ll. is adapted to fit rotatably and slidablf, in the hole in the partition 9 provided. for the tube 7, and the tube 11 has a collar 15 thereon to abut'th'e partition 9 and, limit the forward. movement of said: tube 11. The opposite extremities of the tube 11. are offset so as to be in lines'spaced apart and parallel, as seen in Figs. 2 and 3.

The sleeve 10 is of an internal diameter equal to the external diameter of the tube '2' so that the sleeve 10 can he slid rearwardly on the tube 7 and the rear end of the tube is formed with means for gripping or embracing the tube to hold the sleeve in place. Thus, the rear end of the sleeve 10 is split to form the resilient tongues 16 which are spread or bent apart so as to diverge away from one another, for the purpose of enabling the sleeve to be readily inserted on the tube 7, and for the further purpose of gripping the tube. The tongues 16 have teeth or spurs 17 struck inwardly therefrom to bite the tube under the spring tension of the tongues.

In applying the device, after the short length of the tube 7 has been cut away from the front thereof, the sleeve 10 is slid rearwardly on the tube 7, and the tube 11 is then positioned between the sleeve 1.0 and part-ition 9 and the forward end of the tube 11 is inserted in the hole in said partition which was previously occupied by the forward end of the tube 7, before the tube was cut away. The sleeve 10 is then slid for-' The device includes the sleeve or wardly to slide the forward end or nipple 1 13 thereof into the socket 12, providing a slip connection between the tube 10 and tube 11. The tongues 16 in pressing against the tube 7 Will then prevent the tube or sleeve 10 from sliding rearwardly accidentally, and the sleeve 10 and tube 11 are therefore retained in place, the sleeve 10 holding the tube 11 against rearward displacement. The oil from the tube 7 flows through the sleeve 10 and tube 11 in the same manner as before, and should it be necessary to clean out the oil tube, the sleeve 10 is readily slid rearwardly on the tube 7, and the adjacent ends of the tubes 7 and 11 are so spaced apart that the sleeve can be slid back over the tube 7 out of engagement with the tube 11. The tube 11 can then be turned and withdrawn from the support 9, after which the sleeve 10 can be removed from the tube- 7. This gives access to the forward end of the tube 7, and the parts 10 and 11 are readily replaced after being cleaned out.

It is preferable to knurl or otherwise roughen the sleeve 10 and tube 11, as at 18, so as to be conveniently held in the hand without slipping. Such tubular sections 10 and 11 are conveniently installed after the tube 7 has been cut ofl, and said parts are simple and cheap to manufacture.

Having thus described the invention, what is claimed as new is 1. In a device of the character described,

the combination with a tube and a support spaced from one terminal of the tube, of a sleeve slidably fitting said terminal of the tube, and a second tube having one terminal rotatably engaging the support and the other terminal having a slip connection with said sleeve, the'adjacent ends of the first and second named tubes being so spaced apart that the sleeve can be slid back over the first named tube out of engagement with the second named tube and the opposite ends of the second named tube being oiiset relatively to one another.

2. In a device of the character described, the combination with a tube and a support spaced from one terminal of said tube, of a sleeve slidably mounted on said terminal of the tube, and a second tube having one terminal rotatably inserted in said support and provided with a portion to abut the support, the other end of the seoondnained tube and sleeve having a slip connection and portions abutting one another, the opposite ends of the secondnamed tube being ofi'set relatively to one another, the sleeve having resilient portions trictionally engaging the firstnamed tube to maintain the sleeve in position on the firstnamed tube and to hold the secondnamed tube in engagement with the" support, the adjacent ends of the first and second named tubes being so spaced apart that the sleeve may be slid back on the first named tube out of engagement with n the second named tube.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
