ATTACHMENT FOR PNEUMATIC DRILLS.
Application filed May 4,
The object of this invention is to provide means for conveying the exhaust air from a pneumatic drill, to a point of discharge, in order that the workman handling the drill may not be obliged to breathe the dust usually stirred up by the exhaust air, which frequently results in serious affections of the throat or lungs.
A further object is to provide an attachment including a plurality of tubes so positioned that one tubewill convey the air from each exhaust port and conduct it to a main pipe and thence to an air hose, whereby the expanded air may be conducted to a suitable point o' discharge.
A still further object is to provide for readily connecting the attachment to a drill casing.
`With the foregoing and other objects in view, the invention consists in the novel construction, combination and arrangement of elements described, illustrated and claimed, it being understood that modifications may be made within the scope of the claim without departing from the spirit of the invention.
In the drawings, Figure 1 shows the device in elevation, as applied to the casing of a pneumatic drill; Figure 2 is an elevation from another angle, of the rigid pipe connection for use between the casing and the flexible discharge pipe; Figure 3 is a plan view of the construction ot' Figure 2; Figure Y 4 is a perspective view ot a securing device, `ter mounting the attachment; Figure is an Velevation with parts in section, showing a slight modiiication, in which detachable connections for the branch pipes are provided.
The casing ot' a drill is designated 10 and exhaust ports 1 1 serve the usual purpose, the ports being dilierently spaced on drills of different makes, so that a special attachment will be required for each standard malte ot drill.
Communicating with the ports 11 are short pipes or tubes 12, which in turn have communication with longer tubes 13 preterablv curved or deflected as shown, in order to fit the drill casing.
1923. Serial No. 636,644.
A main tube 14 is of sutlicient size to carry the volume of air issuing tromall of the ports and discharged through. the other tubes just referred to, tube 14 having a threaded end 15 with which an air hose may be connected, so that the exhaust air may be discharged at a suitable distance from the point where the work is being carried on.
lt will be observed from the drawing that he elements 12 and 13 constituting branch pipes, are oitset with reference to the main tube 14, and torni a plurality of pairs of ducts projecting in the direction necessary for establishing communication with the ports of a standard casing, when the main pipe is parallel with the longitudinal axis of the casing.
A bracket 16 may comprise two resilient arms and a central portion 17 passing around the tube 14 and secured thereto. The approaching ends ot the arms are provided with engaging devices 18 and 19, permitting the bracket to be secured to the drill casing.
In one form of the device threaded pipe unions 2O serve to connect the individual pipes with the casing, complementary threaded elements 21 being welded to the casing, in registration with the exhaust ports.
What is claimed is:
An exhaust attachment for a pneumatic drill, including a casing and exhaust ports, said attachment comprising a rigid main pipe, rigid branch pipes offset With reference to the main pipe and forming a plurality of pairs of ducts on each side of the main pipe tor establishing communication with the port-s, when the main pipe is disposed in parallel relation with the longitudinal axis of the casing, and a bracket proportioned to mount the main pipe on the casing in the aforesaid relation to the longitudinal axis of the casing, with the branch pipes in alinement with the ports.
In testimony whereof We attix our signatures.
