W. EIERMANN BORING SPADE Filed Jan. 20', 1921 Patented .lune 5, 1923.
UNHTE STATES WILLIAM EIERMANN, OF BROOKLYN, NEW YORK.
BORING SPADE.
Application led January 20, 19,21.
T 0 all wiz/0m t may concern:
Be it known that I, WILLIAM EIERMANN, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Boring Spades; and I do 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.
This invention relates to an improved boring spade which is especially designed to be used b-y plumbers. It is manually operated and enables the plumbers to form a comparatively lengthy horizontal underground bore in which piping may be laid and thus obviates the necessity of undue excavation which oftentimes ties up traiiic and is a great deal more expensive as is well known.
Another object of the invention is to generally imp-ro-ve upon devies of this class by the provision of one of extreme simplicity and durability which is made up of few readily disconnectible parts, thus enabling the use of diiferent lengths o-f handles, and also permitting the use of diiferent lengths of blades.
Other objects and advantages of the invention will be apparent during the course o-f the following description.
In the accompanying drawings forming a part of this specification and in which like numerals are employed tov designate like parts throughout the same:
Figure l is an elevational view of a boring spade constructed in accordance with this invention, showing one way in which the same may be used.
Figure 2 is an enlarged top plan view of the device.
Figure 3 is a side elevational View thereof.
Figure 4 is a central longitudinal section taken on the plane of the line 4-4 of Fig. 2.
Figure 5 is a transverse section taken on the plane of the line 5 5 of Fig. 2.
In carrying out the invention, I make use of a scoop-like blade 1 of any suitable length, and a handle 2 which, like the blade, will vary in length according to the length of the'bore to be formed, the two parts being connected together by a novel co-nnector 3. While the connector 3 could be of some other construction, I prefer that it be in a form of a casting, the same including a horizontal laterally curved attaching flange ex- Serial No. 438,700.
tending into the rear end of the blade 1 and engaging the inner surface of the latter at this end, and a curved rib or bead 5 against which the adjacent end of the blade abuts. The casting further includes an integral vertically disposed inclined portion 6 disposed at the inner end of said attaching flange and being of a height to substantially close this end of the blade in the manner shown. Furthermore, the casting includes a laterally extending internally screw-threaded socket 7 into which the screw-threaded end of a handle 2 is extended and has screw-threaded engagement, this socket being eccentric to enable easy handling of the device. If desired, a set-screw 8 may be extended through the socket 7 and against the handle to prevent accidental rotation of the latter and thus insure against disconnection of the same. As before stated, it is desirable to have all of the parts of the device disconnectible from one another, `and in view ofthis, I make use of bolts 9 for connecting the blade with the attaching flange 4. It may be stated here that an ordinary length of gas pipe may be employed as a handle for the device.
Ordinarily. in laying piping from the street-main to a house, considerable excavation is necessary and in congested districts, this is undesirable since it oftentimes ties up traffic for sometime and much expense is involved in this method of laying pipes. However, by making use of my novel boring spade, very little or no excavation is necessary, as an underground horizontal bore formed with my spade will suiiice for laying the pipes. In Fig. l of the drawing, I have disclosed one way in which the above result may be accomplished. By referring to this figure, it will be seen that the letter W designates the wall of a building, such as can be worked on from inside of a cellar. At a desirable distance below the pavement P, a hole H is formed in this wall in any suitable way, such as for instance by a chisel. Now, by properly manipulating the spade a horizontal bore B may be formed entirely beneath the pavement, or in fact, entirely beneath an ordinary street, thus overcoming the necessity of excavating any part of the street whatsoever. As before stated, all of the parts of the Spade are easily separated from one another and according to the length of the bore, different lengths of blades and handles will be employed. The exact manner of manipulating the device need not be Set forth here,since this. Will bebetter un,- derstood from actually using it.
A careful consideration ot' the foregoing description taken in connection with the acj companying drawing, is thought to be sullicient to enable persons skilled in thel art to Which the invention relates to obtain a clear understanding of the same.- rllherefore, a more lengthy description is deemed unnecessary.
Doubtless, advantageous and effective results Will be obtained from a device constructed in accordance with my ideas. However, I Wish it to be understood that slight minor changes in the shape, size, and arrangement of parts may be resorted t0 Without departing from the spirit of the invention or the scope of the subjoined claims.
I claim: I
l'. A tool of the class described comprising' a substantialy channel-shaped shovel blade, and a connector for a handle including av transversely curved attaching flange with which one end of the blade is detachably connected, and an integral angularly' dis posed portion extendingy acro'ssone end of the blade and constituting a back, whereby to form a scoop. l
2. A tool of the class described comprising a blade of channel-shaped cross-section, a' relatively long handle, a one-piece' casting forming., a connectingy member for the. handie, said member including a transversely curved attaching flange telescoping into the innerV end. ofk the blade and bearing against the inner face thereof, a similarly curved rib onthe underside 0f said flange for'provid- 3; A tool 0f the 'class described including a one-piece casting constituting a connecting member for a handle, said casting embodying a transverselyv curved attaching` flange adapted for connection With a transversely curved substantially"channel-shaped shovel blade, an integral and inclined portion eX- tending at rightangles from said flange and constitutinga lback for said blade to .form a scoop, acurvedl rib on the under side' of the fla-ngeat the juncture thereof With said portion', said rib' `constituting an abutmentagainst which the adjacent end of the/blade is adapted to bear, and a laterally disposed integral socket for reception of thev handle'.
In testimony whereof I have hereunto set myv hand. t Y v WILLIAM EIERMANN.'
