SAND INJECTOR.
Application filed July 5,
The invention relates to sand pumps or injectors, and is designed for use in elevating mixtures, such as water mixed with sand, mud, oil and other materials which are very difficult to handle with ordinary types of injectors or pumps, and which wear the parts very rapidly requiring frequent replacement or repair. The invention has for its principal objects the provision of an injector which will operate to lift mixtures so thick that heretofore it has been neces sary to remove them with buckets and shovels, and the provision of a device of the character specified which is cheap and simple in construction and which requires replacement or repair only after long periods of use. One embodiment of the invention is illustrated in the accompanying drawings wherein:
Figure 1 is a side elevation of the apparatus. Fig. 2 is an end view. Fig. 3 is a partial vertical section. And Figs. 4 and 5 are detail views of the sleeve employed.
The body portion of the device comprises a tubular bar "el 1 having the flanges 2 and 3 at the lower and upper ends, respectively, for connection with suitable inlet and outlet pipes. The bore of the barrel consists of a main portion 4 of uniform diameter with a tapering portion 5 merging into an enlargement 6 at the lower end of the barrel. Opposite the enlargement 6 is a boss 7 pro vided with an inlet passage 8 for supplying an operating fluid under pressure, such as steam to the enlargement 6. 3
Fitting into the enlargement 6 is the sleeve 9 screw threaded at 10 for engagement with the screw threads 11 at the lower end of the barrel. The sleeve is provided with a shoulder 12 adapted to engage the shoulder 13 at the inner end of the enlargement 6 when the sleeve is screwed into position. The extreme end 14 of the sleeve fits into the tapered portion 5 of the barrel, but is spaced away therefrom, as indicated at 15 in Fig. 3 to provide an annular inlet space for the passage of the steam from the enlargement 6 to the interior of the barrel. The sleeve is also provided with a plurality of grooves 16 of a, depth as indicated in Fig. 3 so as to readily permit the passage of steam from the enlargement 6 to the annular space 1923. Serial No. 649,629.
1 15. In order to give opportunity for the application of a wrench to the sleeve to screw it in position, the sleeve is provided at its extreme lower end with the inwardiy projecting lugs 17.
As indicated in Fig. 3, the bore of the sleeve 9 is of the same diameter as the bore 4 of the main portion of the barrel and is in alignment therewith so that no obstrucs tion is offered to the flow of material through the device and any material which passes into the lower end of the injector will be free to pass through the bore 4 with out obstruction. through the annular space 15 at a high velocity carries with it the more or less solid material contained in the sleeve and in the barrel and protects the surface of the bore 4 to a large extent from the frictional wearing effect of such material, which is an importantfactor when the material is of an abrasive character such as sand and would tend to cut away the inner surface of the barrel. The device is particularly advantageous in handling very heavy mixtures, such 5 as the mixtures of sand and mud which collect in the wells or sumps employed in connection with grinding and polishing machines in the manufacture of plate glass, and which otherwise have to be cleaned out by hand by the use of shovels and buckets. The advantages of the construction incident to its cheapness and simplicity of construction will be readily apparent to those skilled in the art.
What I claim is:
In combination in an injector for lifting heavy mixtures of water and sand or mud, which comprises a tubular barrel open from end to end, with an enlargement at one end, and a tapering portion connecting said enlargement with the portion of the bore of smaller diameter, a shoulder at the junction between the enlargement and the tapering portion, a sleeve fitting into said enlargement with its outer surface spaced away from the wall of the enlargement throughout a portion of its length and provided at its inner end with a shoulder engaging said shoulder on the barrel and having a portion of reduced diameter at its forward end pro jecting into said tapering portion but spaced The steam passing up away therefrom, and a communication or threaded at its outer end into said enlargesupplying fluid under pressure to the space ment. between the sleeve and the Wall ofthe en- In testimony whereof, I have hereunto 10 ,largement, the said sleeve being provided subscribed my name "this 19th day Of June,
