Application filed January 29, 1912.
Specification of Letters Patent.
Patent-ed Got. 29, 1912.
Serial No. 673,991.
To all whom it may concern:
Be it known that I, NICKLAUS W. Islam, a citizen of the United States, residing at 800 St. Clair avenue, Milo, in the county of Franklin and State of Ohio, have invented certain newand useful Improvements ,1 in Fl-uid-Pressure-Actuated Hammers, of which the following is a specification.
The present invention relates to improvementsin fluid. pressure actuated hammers,
proved form of hammer of this type embodying several meritorious features.
The invention consists in certain novel features of construction and combinations and arrangements of parts as fully pointed out in the following specification and claims, and illustrated in the accompanying drawings.
In the drawings I have illustrated one example of the physical embodiment of my invention constructed according to the best mode I have so far devised for the practical application of the principles, and which is highly satisfactory in actual use.
In the drawings wherein like characters indicate similar parts throughout: Figure 1 is a vertical central sectional view of a motive, fluid actuated hammer embodying the features of my invention, parts being broken away for convenience of illustration. Fig. 2 is a sectional View similar to Fig. 1, in
part, but taken on a plane at right angles to the plane of Fig. 1. Fig.3 is a detached perspective view of one of the casings or sleeves forming a part of. the device, and Fig. 4 is a perspective view of a sectional sleeve or housing forming part of the device.
For convenience of description the device will hereinafter be referred to as a pneumatic hammer, but it will of course be understood that the invention may be embodied in hammers employing other motive fluids, as steam. Y
As illustrated in Fig. 1 of the drawings the device is shown as applied to a usual or comprises the tube 1, which forms a cylinderstandard type of pneumatic hammer which in which the piston or plunger 2 may be actuated by compressed air in manner well understood, through the handle 3 and the flexible pipe 4. I
-- In applying the device to the ty ical tool such as a riveter 5, which is one of a series or set illustrated in the drawings, a too of tools that accompany-and may .be used with the hammer. The riveter is formed With a head 6 provided with a conical depression or recess 7 (dotted lines) and the stem or shank 8 has an integral collar 9 in which an annular recess or groove 10 is provided for the reception and retention of a conoidal spring 11 which surrounds the portion 5 of the riveter.
The shank 8, under normal conditions and in operative position is fitted within the bore of the tube 1, with the shoulder or collar 9 in contact with the end of the tube. The spring 11, collar 9, and a portion of the riveter are inclosed within a sectional housing, composed of the two members 12, 12 (see Fig. 4) exteriorly threaded as at 13, and provided with end flanges 14 forming an opening 15 through which the riveter 5 is adapted to move.
It will be observed that the exterior perimeter of the sectional housing and the tube 1 are identical, so that an interiorly threaded casing 16 1s adapted to screw onto the threaded sectional housing and likewise engage the threaded portion 17 of the tube 1. In this manner, the housing is connected to the tube 1, and to insure against relative movement of the parts, set screws 18 and 19 may be employed, the former to lock the casing and tube, and the latter to lock the casing and housing.
In assembling the parts, the spring is screwed on over the collar 9 and the shank 8 placed in the tube 1. The housing members 12 are then placed about the riveter and inclose the spring between the flanges 14: and the collar 9, and finally the casing 16 is threaded onto the sectional housing and the threaded end of tube 1;
In operation the plunger 2-is actuated and reciprocated in suitable manner and strikes the end of stem 8 imparting a blow thereto. The blow drives the riveter against the tension of the spring, to strike and hammer a rivet head, as will be understood. The housing effectually prevents the escape of the riveter or spring, but is at the same time, capable of easy attachment or removal when it is desired to change the. style of tool head employed, and the spring ma terially eliminates the vibratlons and pound ing usually met with in these tools.
From the above description taken infcon-l',
nection with the drawings it is evidentth I have provided a device of this character,
possessing meritorious features, and While- I have illustrated only one example ofits physical embodiment, it should be understood that colorable changes and alterations may be made without departing from the scope of the appended claims.
What I claim is 1. The combination, with a motive fluid actuated device as described comprising a tube, of a headed tool and a shank in said tube and a collar adapted to rest against the end of said tube, a spring surrounding a portion of said tool shank and bearing against said collar, a sectional housing formed with end flanges \inclosing and retaining said spring, and a casing connecting said housing with said tube. v
2. The combination in a motive fluid acbearing against said collar, a sectional hous;
ing having exterior screw threads and formed with end flanges inclosin and retaining said spring, and an lnteriorly threaded casing screwed onto said sectional housing and threaded tube end.
In testimony whereof I aflix my signature in presence of two witnesses.
