NOZZLE.

Specification of Letters Patent.

Patented J an. 12, 1915.

Application led February 28, 1913. Serial No. 751,201.

To all 1li/:0m it may concern Be it known that I, NrLs FREDERICK AM- isunsnN, a citizen of the United States, and a resident of Brookline, in the county of Norfolk and State of Massachusetts, have invented a new and useful Improvement in Nozzles, of which 'the following is a specication.

My invention relates to nozzles for receiving and mixing dry comminuted material with liquidand discharging such mixture under pressure, and more especially to nozzles for cement guns, so called, or devices for forcibly projecting cement-mortar and the like, as described in United States Letters Patent-to C. E. Akeley, 984,254, granted February 14, 1911.

The object of my invention is to improve and simplify the construction and increase the /efficiency of such nozzles in the manner hereinafter set forth.

Heretofore, so far as I am aware, it has been necessary to force the liquid into nozzles of the kind to which the present application relates, under pressure, and to apply the same to the exterior of tbe stream of dry comminuted material. By means of the present invention it is not necessary to employ liquid under pressure, although it mav be so employed if desired, and the liouid is injected directly into the interior of the stream of dry comminuted material, thereby insuring greater uniformity of mixture tb an when it is applied to the exterior thereof.

Two embodiments of my invention are shown in the drawings which accompany and form a part of this application.

In the drawings, Figure 1 is a longitudinal section of my improved nozzle. Fig. 2 is a section taken on the line 2--2 of Fig. 1, and Fig. 3 is a fragmentary section on an enlarged scale. Fig. 4'is an end view on a smaller scale of a modified partition, and Fig. 5 is a section taken on the line 5-5 of Fig. 4.

In the particular drawings selected for illustrating the principle of my invention, 1 represents a sleeve having its forward portion outwardly flaring to form an expansion chamber 1', hereinafter more fully referred to` and its rearward portion adapted to be secured by threads or other suitable means to the hose 2 for conveying dry comminuted material under pressure to the nozzle. In the present instance the screws 3 are employed to secure the union between the sleeve and hose. Extending across the expansion chamber 1 -formed bv the enlarged forward portion of the sleeve is the partition 4, shown herein as rearwardly municates also with an outlet located in tbe forward edge of the partition about midway between the ends thereof. so that it is approximately in the center of tbe expansion chamber. In tbe present instance the outlet consists of tbe forwardlv-projeeting pipe 7 screwed into the forward ed ge of the partition and provided with orifices 7 7 preferably divergent. said outlet pine also being of much smaller internal diameter than the hose 2 and tbe combined cross-sectional areas of said orifices being preferably not larger than tbe cross-sectional area of said outlet, as indicated in Fig. 3.

The usual soft rubber liner"9 is provided to line the interior of the expansion chamber 1 formed as aforesaid bv the forward portion of the sleeve 1, and a suitablyslianed discharge nozzle 10. also of soft rubber, is held in alinement with the liner 9 bv means of the shouldered nut 12. which compresses the Hanges of the liner 9 and discharge nozzle 10 against the outer face of the sleeve. In the present instance the discharge nozzle is shown as tapering forwardly from the expansion chamber to a point at a short distance from the end of the nozzle, beyond which the nozzle is cylindrical. The shape of the nozzle causes it to act asa compression chamber for compacting the material after it has expanded and has been mixed with the liouid in the whatever plastic compound is desired to be delivered. In this connection it will be unte prevent. abrasion by., the. .comminuted material.

In operation, the` hose 2 is connected to any of`the usual types of apparatus for forcing therethrough by compressed air dry comminuted material such as cement or lime, sand, and the like, which after admixa( ture with water, form cement mortar or pansion chamber l', it will be divided intof two'streams which passon either lside of f said partition and which, being under pressure,`fill the expansion chamber except immediately in front of the outlet pipe 7 where there will be a clear space. Into Athis space by meansof the outlet pipe '1, liquidsuch as water issprayed through the orifices 7 7 such liquid being injected directly into the interior of the streamofv nfiaterial.y As the stream of material is passing-thev 'partitioni and outlet pipes' at a high rateot speed, it will create sufficient suction to force' the liquid throughthe pipe 8, duct 6 and outlet pipe 7, so, that it isunnecessary to force the liquid into the nozzle under pressure as has heretofore been required, although of 'coursei' it will be understood that liquid under pressure may be employed, such for-,example as water .under the @usual pressure of a waterworks delivery main.

Whenthe. mixture of comminuted'material and liquid passes from'theexpansion chamber to the compression' chamber, it is .compactedI preparatory; t0? being ,ejected from the cylindrical end of the-nozzle, and

during the process of compacting, the liquid passes from ,the central to the-outer vportion of the' streamof material and' thus penne-- ates; the entire mass, so that'the mixture as inally ejected will have`,the.idesired degree of plasticity.

' In Figs. 4 and 5, the partition Llaf-:has its rearward edge twisted somewhat in theman-v ner'of a propeller bladevv and extending diagonally across Ithe yexpansionA chamber,- while its forward edge, as in Fig. 1,- extends.

diametricallyacross the same. :The stream or rotary motion, so that after the water has .been injected into the interior of the stream as above described, and. the plastic mass compacted by the compression chamber, it will leave the nozzle as a whirling spray and will be distributed over a larger surface f area. This is advantageous for laying on tle iinishing coat of cement-mortar or the 1i ie.

l/Vhile I have speciically described two particular embodiments of my improvement, it will be understood that various modifications may be made therein by those `skilled in the art, without departing from the principle4 of my invention.
