VICTOR C. VANT VOUD, OF NFV YORK, N. Y.

SYRlNGE-PIPE.

SPECIFICATION formingpart of Letters Patent No. 737,795, dated September 1, 1903.

Application filed May 18,1903. Serial No. 157,635. (No modelh T0 a/ZZ whom it ntcty concern,.-

Beit known that LVIeToR C.VANT WoUD, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Syringe- Pipes; and I 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 usethe same.

My invention relates to syringe pipes or tips, and has for its object to produce such pipe-tips whichwill be adapted to throw a circular spray in either a forwardly or backwardly direction, as desired. To accomplish this result, I employ the new and novel construction hereinafter fully and clearly described and illustrated.

In the drawings, Figure 1 is a side or longitudinal view of my improved construction when adapted to throw a forwardly-extending spray. Fig. 2 is a longitudinal sectional view of the saine. Fig. 3 is a longitudinal sectional view of my construction when adapted to throw a backwardly extending spray. Fig. 4 is a perspective view of the parts of the spray attachment. Fig. 5 is a perspective view of the end of my improved pipe.

In the drawings like letters of reference designate similar parts of my construction.

A in the drawings represents a hard-rubbertube of suitable size and shape with either a plain or iiuted exterior surface, said tube having one end closed Vor sealed and having its other end attached to a syringe by any suitable means, as the rubber tube B. This tube A is provided near its closed end with an annular groove a and outlet holes or ports a' a' in said groove a. O is an attachment, preferably oval-shaped, adapted to tightly fit on said tube in such a manner as to cover the groove c. and outlet-holes a'c'. This attachment O preferably comprises two interlocking portions c c, as shown in Fig. 4; but, if desirable,itn1ay be constructed in one piece. c c are each provided with suitable threads e c', adapted to engage similar threads a2 a2 on the tube A to retain said attachment O in position on said tube and to enable it to be reversed when desirable. Said oval attachment C is provided at its center with an. an-

lnular groove c2, the sides of said groove being preferably oblique. c3 c3 are passages in the attachment connecting the grooves a and c2. Thus when liquid is admitted to the tube A from a syringe it passes to the closed end of said tube and is forced through 'the holes a a' into the groove a, then through the hole c3 c3 into the obliqu ely extending groove c2, from which it is thrown in the form of a spray either in a forwardly or baekwardly extending direction, according to the manner in which the attachment C is placed on the tube A, and it is obvious that the direction of the spray may be easily regulated, as desired, by reversing the attachment C on said tube A.

Vhat I claim, and desire to secure by Letters Patent, is-

l. In a device of theclass described,the conibination with a tube, of a reversible spray attachment detach ably secured to said tube and having a discharge inclined to the`longitudinal axis of the said attachment, whereby the direction of the spray is controlled by reversing said attachment, substantially as described.

`2. In a device of the class described,the combination with a tube closed at its outer end, and provided with lateral discharge-apertures, of a reversible spray attachment hav-v inga central longitudinal aperture to fit over said tube and provided between its ends with a lateral discharge inclined to the longitudiportion and the outer end, of a reversible IOO vided with a suitable annular groove and outports being in communication with the groove let-ports in said groove and in eommunieaand outlet-ports in said lcube, said attachment tion with the groove in said tube, said attaohbeing adapted to be reversed, substantially ment being adapted to be reversed, substanas und for the purpose described. I5 5 tally as and for the purpose described. In testimony whereof I afx my signature 5.
