' Specification of Letters Patent.
Patented Sept. 15, 1908.
Application filed August 20, 1907. Serial No. 389,379.
To all whom it may concern:
Be it known that I, WILLIAM PRELLWITZ, a citizen of the United States, and resident of Easton, in the county of Northampton and State of Pennsylvania, have invented a new and useful Brace Attachment for Fluid- Pressure Operated Tools, of-Which the following is a'specification.
The object of my invention is to provide the ,protective casing of a fluid pressure operated tool with a brace which may rest uponthe ground or other surface to form an end support therefor and which will, at the same time,- ermit the free manipulation of the tool wit in its protective casing.
The invention is particularly well adapted for use in connection with percussive tools of the air feed hand rotation type, in which'the tool is carried by and free to be moved longitudinally and axially in a protective casing, the brace which is carried by the casing being extended to the rear of the tool handle an i there provided with an end piece arranged in alinement with the axis of the tool.
ra'ctical embodiments of my invention are represented in the accompanying drawings, in which the invention is shown as applied to a hammer drill such as that shown, described and claimed in United States Letters Patent No. 818,638, dated A ril 24., 1906.
Figure 1 represents one em odiment of my invention in side elevation, partially in section, in which the brace is removably carried -by the rotective casing and the end piece is adjusta 1y carried by the brace, Fig. 2 is a detail side view in which the end piece is permanently carried by the brace, Fig. 3 is a detail plan view of the removable wedge connection between the brace and the protective casing, Fig. 4 is a detail section showing the brace as permanently carried by the rear head of the protective casing, Fig. 5 is a detail planview partially in section showing a brace ofloop form instead of the single arm shown in the other figures, and Fig. 6 isa view showing the application of the device.
The fluid pressure operated tool shown herein is a'hammer drill, the tool cylinder of whichis depoted by 1, the head block by 2, the valve ,box by 3, the tail rod by 4, the drill tool by 5 and'the bushingb 6. The tail rod is provided with the usua handle 7 for manipulating the tool.
' dle 18 if so desire 'nipulation of the tool.
The protective casing is denoted by 8 and casing. The tool is thus supported with the casing spaced therefrom.
The brace, which is carried by the casing for forming an end support therefor, comprises an arm 11 which 18 herein shown as of T form in cross section to give it the required strength, which arm is provided at its front end with a wedge 12 arranged to be removably inserted in a taper socket 13 on the rear head 10 of the protective casing 8. This brace extends. to the rear of the handle 7 of the tool and is provided with an inwardly turned end 14 from which extends a socket piece 15 within which is adj-ustably secured an end piece 16 which is in alinement with the axis of the tool and is fitted to enga e the ground or other surface when the too is in 1 operation.
The means which I have shown foradjustably securing the end piece within the socket piece 15 is a set screw 17. The front end-of the cylinder 1 of the tool, exterior to the protective casing, ma be provided with a han-' for assistance in the ma- In the form shown in Fig. 2, the end piece 19 is shown as per manently secured thereto. In the form shown in Fig. 4, the brace is shown as forming an integral part of the rear head 10 of the rotective casing. In the form shown in ig. 5, I have shown the brace as of loop form, so as to permit thecomplctc rotary movement of the handle of the tool.
By the use of the brace in connection with tools having a protective casing, I am onabled to provide a very simple and effective end sup )ort for the casing in alinemcnt with the tool thus relieving the operator of the weight of the tool and yet at the same time cr1nitting the tool tobe read il manipulated to produce the most satls actory results.
and an adjustable end piece carried by the brace for engaging the ground or other surface. 1
2. A hollow protective casing, a tool slidably su' ported therein, a brace removably carried y the casing forming an end support therefor and an adjustable end piece carried by the brace for engaging the ground or other surface.
3 A protective casing, a ercussive tool supported therein having its andl e located exterior to said casing and a brace carried by the casing extended to the rear of the han' dle and forming an end support for the casing.
4. A protective casing, a percussive tool supported therein having its handle located exterior to said casing, a brace carried by the casing extended to the rear of the handle and forming an end support for the casing and an end piece carried by the brace for engaging the ground or other surface.
5. A fluid pressure ,feed hand rotated percussive tool, a protective casing therefor, a brace carried by the casing and an end piece carried by the brace inalinementwith thebrace carried by the casing and an adjustable end piece carried by the brace in alinement with the axis of the tool.
8. A fluid pressure feed hand. rotated percussive tool, a protective casing therefor, a brace removably carried by the casing and an adjustable end piece carried by the brace in alinement with the axis of the tool.
In testimony that I claim the foregoing as my invention, I have signed 'iny naine in presence of two Witnesses, this 16th day of August, 1907/ WILLIAM PRELLWITZ. Witnesses:
