SPRAYING'DEVICEJ a William Moreland, Bloomfield, N.'. 1. Application rune 7,1941,-SerialNo. 397,054

' 2 Claims.

- This invention relates to improvements in spraying devices and more particularly to devices'for the spraying of cementitious material on surfacesfor waterproofing and similar purposes.

An object of my invention is to provide a portable spraying device incorporating novel features of construction whereby rapid and efficient means are provided for spraying or projecting the cementitious material at a predetermined thickness and quantity under pressure.

Another object of my invention is to provide novel means for maintaining an air line in the device of my invention at constant spring pressure to normally close the orifice through which the cementitious material is ejected in the device of my invention in the line of the compressed air nozzle.

A further object of my invention is to provide a compact spraying device adapted for ease of handling and adjustment and which is positive The trigger 2| is provided with a bifurcated upper end 23 which is adapted to freely slide along the flattened portion 24 of the nozzle 14 upon the actuation of the trigger 2|, the latter :being preferably provided with a weighted lower end 25 to normally urge the bifurcated end 23 of the trigger rearwardly and into abutment with a ring 26 fixed to the nozzle I4 in any desired or convenient manner so that upon the depression of the lower end 25 of the trigger the nozzle I 4 will be urged rearwardly. The nozzle I4 is normally urged forwardly by spring means 27 which, in the embodiment of the invention shown in the drawing, bears at opposite ends against the washer I2 which is fixed to the chamber In and against circumferential flange 28 integral with the cylinder 29, the latter being provided Fig. 3 is a partly sectional fragmentary view taken on line 3-3 of Fig. 2 in the direction of the arrows.

Referring to the drawing, wherein like reference numerals indicate like parts, the spraying device of my invention comprises a cylindrical chamber 10 provided with a collar ll defining the forward end thereof, a collar l2 secured to and defining the rear end thereof and a medial collar l3. A compressed air nozzle I4 is slidably arranged in chamber l0, said nozzle [4 having fixed to one end thereof a compressed air line l5 which is in communication with a compressed air source (not shown), the other end of the nozzle 14 being beveled at l6 and normally seating against the corresponding beveled seat I! of the collar II, the latter being provided with a centrally arranged aperture 3.

The chamber Ill is provided with a handle [9 secured thereto in any desired or convenient manner, said handle being provided with a boss 20 on which a trigger 2! is pivotally secured by a pivot pin 22 or the like.

with a flanged head H; the cylinder is internally threaded for threaded engagement with the external threads 30 of the nozzle I l.

The cylindrical chamber In is provided with an aperture 3| intermediate the spaced collars II and I3 thereby defining a pocket 32 for the reception of cementitious or other material to be sprayed by means of the device, the chamber Ill being provided with a tubular member 33 in registry with the aperture 3| and therefore in open communication with the pocket 32 so that by coupling the member 33 with a pipe (not shown) or hopper 34 the pocket 32 may be provided with a supply of cementitious or other material to be sprayed. In the embodiment illustrated in the drawing the hopper 34 is provided with means 35 for suspending the device from a suitable support or for securing the hopper to a cementitious supply source, the upper end 36 of the hopper being preferably closed at its rearward portion so that the angular rearward tilting of the hopper will not result in the escape of material therefrom.

From the foregoing it will be noted that the pocket 32'is normally closed by the seating of the nozzle l4 against the collar II, the nozzle l4 preferably having a close sliding fit in the aperture 31 of the medial collar l3 to seal the pocket 32 at that point.

The amount of material ejected or sprayed from the device of my invention and. therefore the thickness of the coating of cementitious material applied by my device depends upon the degree to which the nozzle I 4 is retracted against the tension of spring 21 and therefore on the amount of space S (Fig. 3) between the nozzle end It and the aperture I 8.

In the embodiment of the invention shown in the drawing this variation is obtained by providing for the varying of the position of the ring 26 of the nozzle I4 relative to the flange 28 of the cylinder 29, this variation being attained by the rotation of the flanged head H of the cylinder 29. It will be apparent that the tension of the spring 21 will serve to normally maintain the nozzle l4 seated on the collar ll regardless of the particular position of the ring 26 relative to the flange 28 of the cylinder 29 and that as the nozzle l4 may be retracted until the full compression of the spring 21, variations in the width of the space S and therefore in the quantity of ma.- terial adapted to pass in line with the nozzle l4 may be accordingly attained and varied from;

time to time in a rapid and eificient manner.

Having thus described my invention, what I claim as new and desire to secure by Letters'Patient is: c

1. In a spraying device, a cylindrical chamber adapted to receive a supply of spraying material, said chamber being provided at one end with an aperture for the ejection of said material and being provided at the other end with a collar, a compressed air nozzle slidably arranged in said chamber and adapted to seat against the aperture to close the same against the discharge of material and adapted to cooperate therewith for the ejecting of material through the aperture when retracted therefrom,-a cylinder threadedly engaging the nozzle and passing through the collar, said cylinder being provided with a circumferential flange at one end and with a head at the other end, spring means engaging the flange and collar. to normally maintain the nozzle seat ted against the-apertureand axtrigger pivotally.

secured to the device and adapted to engage the nozzle to retract the latter from the aperture against the tension of the spring means, whereby, on threadedly rotating the cylinder on the nozzle, the juxtaposition of the cylinder flange and collar may be varied to vary the tension of the spring means and therefore the degree to which the nozzle may be retracted.

2. In a spraying device, a cylindrical chamber adapted to receive a supply of spraying material, said chamber being provided at one end with an aperture for the ejection of said material and being provided at the other end with a collar, a compressed air nozzle slidably arranged in said chamber and adapted to seat against the apertureto close the same against the discharge of material and adapted to cooperate therewith for the ejecting of material through the aperture when retracted therefrom, a cylinder threadedly engaging the nozzle and passing through the collar, said cylinder being provided with a circumferential flange at one end and with a head at the other end, spring means engaging the flange and collar to normally maintaining the nozzle seated against the aperture, a ring fixed to the nozzle and a trigger pivotally secured to the device and adapted to engage the ring to retract the nozzle from the aperture against the tension of the spring means, whereby, on threadedly rotating the cylinder on the nozzle, the juxtaposition of the cylinder flange and collar may be varied to vary the tension of the spring means and therefore the degree to which the nozzle may be retracted.
