MEANS FOR LOCKING OUTLET VALVES IN POSITION.
Application filed August 16, 1926. Serial No. 129,642.
This invention relates to locking and unlocking means adapted to lock an outlet valve gland on the face plate of a device for blowing or shooting material, such as cement and sand, into place.
The invention is particularly adapted for use in connection with an instrument into which suitable material mixed dry is placed and travels therethrough in stages, being 1 fed in measured amounts to the outlet where it is driven out by air pressure and is driven through a hose and nozzle by which the material is directed to the desired location. At the nozzle, water is introduced through the 1 walls thereof in jets at higher pressure than the air, thereby causing the jets to puncture the stream of flowing material. The action of the air in the main hose causes the water from these jets to become atomized resulting in the covering of all the particles with fine spray. When the material is impelled against t e surface to be coated there is considerable rejection of sand, but after a film of neat ce ment is formed, the sand begins to take seat and the percentage of rejection decreases.
There continues to be a certain amount of rejection of the inert material or sand but each grain of sand performs the function of a tamper for the receding material. 4
It has been ound necessary to remove the outlet valve gland for cleaning at intervals, such as at the end of the days operation or at other times. Heretofore, it was customary to secure such a sleeve or outlet valve gland to a face plate of the shooting device by screws passing through a flange of the gland and threaded into the face plate. This arrangement was inconvenient but appeared to be necessary to give the required connect-ion.
An important object of the present invention is to provide means adapted to secure the outlet valve firmly in position and to permit quick and convement release thereof when r u1red.
ther objects and advantages will appear upon consideration of the following detailed description and the drawings, in which:
Fig. 1 is a sectional view illustrating an application of one embodiment of the inven 50 tron;
Fig. 2 is a side view of part of the structure illustrated in, Fig. 1; and
Fig. 3 is a view illustrating one member of the locking device.
In the apparatus illustrated in Fi 1, the mixed sand and cement is supplie in the tank or hopper 10, is agitated by the member 11, and moves into compartments in the peri hery of the feed wheel 12. The contents 0 the compartments are fed from one compartment at a time into the right hand position illustrated in *ig. 1. When any compartment is in a position below the mouth of an air duct 13in an outlet valve body 14, the material therein is driven outwardly through the outlet member or gland 15. The outlet member 15 fits into an opening in the outlet valve body or member 14 and is provided with a flange 16 which engages the member 14 and also serves as a portion of the means for locking the outlet 15 in position.
The outlet valve body 14 comprises a face plate 17 which is secured to the wall of the hopper 10 by suitable means such as set screws 18 screwed into the base 19. Projecting outwardly from face plate 17 are the threaded ends of bolts 20 passing through openings 21 in levers or members 22 which are positioned by spacers 23 and are held thereagainst by nuts 24 and lock nuts 25.
The levers 22 have cam portions 26 and after the outlet member 15 has been placed in position with the levers 22 in the dot-and-dash positions in Fig. 2, the levers 22 are shifted to theirfull line positions and the cam portions 26 are utilized to force the member 15 against the member 14. When it is desired to release the member 15 for cleaning or other purposes, all that is necessary is to shift the levers 22 to releasing position.
In the form of device disclosed herein, the member 15 is used as a gland to hold in position a nozzle-shaped rubber valve member (not shown) through which the material is forced by the compressed air.
It should be understood that various changes may be made in the construction and surface of the hopper to which it is secured, an outlet passage in said plate to receive material from compartments in a feed wheel in the base of said hopper, a flange at the outer end of said outlet passage, and an inlet passage in said plate to receive compressed air ata point above said outlet passage so as to expel through the latter material in a compartment of the feed wheel at said outlet; of a gland having a tubular portion fitting in the outer end of said outlet passage and flange means to engage the flange at the outer end of the outlet passage, and cam devices attached to said valve body at opposite sides of said outlet passage and adapted to en age the flange means of the gland and press t e same into close engagement with the flange on said valve body.
In testimony whereof we hereby afiix our signatures.
