FRANK ADKINS, OF WHEELING, WEST VIRGINIA.
HOSE-NIPPLE FOR AIR-HAMMERS.
Specification of Letters Patent.
Patented Aug. 26, 1919.
Application filed May 3, 1919. Seria1 No. 294,554.
To all whom it may concern Be it known that I, FRANK AnKINs, a citizen of the United States of America, and resident of lVhecling, county of Ohio, and State of West Virginia, have invented certain new and useful Improvements in Hose- Nipples for Air-Hammers, of which the following is a specification.
This invention relates specifically to nipples for air hammers, and it has for its primary object to provide an improved hosenipple structure whereby rubber air-hose may be so attached to air hammers that chance detachment and leakage are effectually prevented.
A further object is to provide a device of the character mentioned which is not only simple and inexpensive in construction, but which obviates various objectionable features of the nipples which are commonly employed as couplings for the air conducting hose of air-actuated hammers.
In describing the invention in detail, reference is had to the accompanying drawings, in which Figure 1 is a side elevation of the invention showing an air hose attached thereto;
Fig. 2 is a longtitudinal section of the same; and- Fig. 3 is an end elevation of the invention.
Referring to said drawings, in which like designating characters distinguish like parts through the several views 1 indicates a collar-like body member having an integral reduced shank 2 extending outward from one face thereof. Said shank is exteriorly threaded to receive the end of the usual bushing (not shown) whereby connection is made with the butt of an air hammer. Also formed integral. with the body 1 is a hollow cylindrical nipple 3 which is axially alined with said shank 2 and extends in a direction opposite to that of said shank. Said nipple is designed to receive thereon the end of a. flexible hose 1- through which air is conducted under pressure for actuating the air hammer to which the device is attached, as aforesaid.
Formed integral with the body 1 and normally lying approximately parallel to and at a suitably spaced distance from said nipple 3 is a plurality of long resilient fingers 5, each terminated at its outer end by a spur G which is inclined slightly rear ward and toward the axis of the nipple.
Said fingers are designed to have their outer ends bent inward slightly following application of the hose -:t to the nipple, to cause "the spurs (S to indent the thereby engaged portions of said hose to the extent that said portions are caused to seat in an annular groove '7 formed in said nipple adjacent to the outer end of the latter. Thus, not only do the spurs sink into or embed themselves in the hose for resisting withdrawal of the latter, but they also serve to depress knoblike portions, as l", of the hose into the scat constituted by the annular groove 7 for more ell'ectually guarding against witlulrawal of said hose.
As herein depicted, the body 1 is of hexagonal form, :ulaptiug it for receiving a Wrench thereon for ell'ecting attachment and detachment of the device with respect to the bushing or other form of coupling by means of which it is attached to the air hammer. Ilowever, it will be obvious that this body may be made of circular or any other appropriate form.
The chief objection to ordinary forms of nipples is that after one or .more hours use the nipple-receiving end of the hose becomes expanded or stretched by the air pressure conducted to the extent that leakage occurs and that said end slips from the nipple. This objection is obviated by the present invention, the fingers thereof serving to so clamp the hose at a point adjacent to the free end of a relatively long nipple that little or no. air is permitted to leak past to a point where it can act to expand the free end of the hose.
lVhat is claimed is- 1. A hose nipple for air hammers, comprising a body having a hollow threaded shank at one side thereof for coupling to an air hann'uer and having at the opposite side thereof a hose-receiving nipple, said shank and said nipple being axially alined, said nipple having an annular groove therein adjacent to its outer end, and a plurality of fingers extending rearward from said body approximately parallel to and at a spaced distance from said nipple, said fingers being terminated by inwardly directed spurs and being adapted to be bent down upon the hose for depressing portions of the latter into said groove.
2. A hose nipple for air hammers, comprising a cylindrical nipple adapted for the reception of the end of a hose thereon, said nipple having an annular groove therein adjacent to its outer end, a threaded shank alined with said nipple and provided With a bore which joins axially With that of said 5 nipple, a collar-like body occupying an external position intermediate said nipple and said shank, and a plurality of fingers formed integral With and extending rearward from said body, said fingers having l0.inwardly directed spur-like terminals adapted to be embedded in the hose and to depress knoblike portions of the latter into seating position in said groove.
In testimony whereof, I affix my signature in presence of tWo subscribing Witnesses.
FRANK ADKINS.
