2 Claims.

This invention relates to mortar applying devices.

An object of this invention is to provide a device for applying at least two parallel strips of mortar on a tile in one operation.

7 Another object of this invention is to provide a device of this kind which is initially dipped into a batch of mortar for picking up at least two strips ofmortar which are applied to the tile in a single operation.

A further object of this invention is to provide in a mortar applying device of this kind, means for holding the device in the desired position with respect to the tile so that the mortar may be applied to the tile in an even depth and in uniform positions.

With the above and other objects in view, my invention consists in the arrangement, combination and details of construction disclosed in the drawings and specification, and then more particularly pointed out in the appended claims.

In the drawings,

Figure 1 is a detail plan view of a mortar applying device constructed according to an embodiment of this invention,

Figure 2 is a detail side elevation of the device,

Figure 3 is a sectional view taken on the line 33 of Figure l,

' Figure 4 is a fragmentary sectional view taken on the line 4-4 of Figure 1.

Referring to the drawings, the numeral I ll designates generally a frame structure which is formed of a pair of end plates II and I2, having upper flanges I3 and M respectively. The end plates have secured therebetween a body plate I5 which is secured between the end plates by any suitable means, and the body plate I5 is formed at the opposite lengthwise edges thereof with upwardly offset truncated V-shaped channels I6.

The channels it open downwardly and angle fastening means I'l are secured to the opposite ends of the channels I6 and to the end plates. The body plate I5 is formed with at least a pair of upwardly extending ears I8 which may be secured by rivets or spot welding, as indicated at I9, to the inner sides of the end plates.

The end plates II and i2 are of like construction and each end plate is formed in the lower edge thereof with a truncated V-shaped cutout All and the upper edge of the cutout is defined by an inwardly projecting flange ZI. The cutout 20 forms a pair of positioning legs 22 whereby the end plates may be properly positioned over the upper end of a tile T, as shown in Figure 3. The marginal edges of the end plates II and I2 are braced by angled bracing flanges 23 and a foot flange 28 is formed at the lower end of each leg 4 Each channel I5 is adapted to be normally closed by an elongated valve or gate 25. The valve or gate25 is formed by bending an elongated flat strip upon itself to form a V-shaped valve member, as shown in Figure 3, and an elongated rod 26 extends between the end plates II and I2, being formed with a head 27 at one end and a cotter pin 23 is extended through the other end for holding the rod 26 against endwise movement. In this manner the rod 2'! may be withdrawn for either repairing a valve or taking the valve from the frame for cleaning thereof, Where the mortar or mud adheres to and dries on the valve.

These two valves are pivoted at their outer lengthwise edges and are adapted to be swung downwardly to open position by downward movement of pairs of valve operating rods 29. The rods 29 are extended at their lower ends loosely through openings 30 formed in the inner small edgesof the valves 25, and a lower cotter pin 3I is extended through the lower rod 29 and is adapted to bear against a washer 32.

- The upper cotter pin or fastening-member 33 extends through the rod 29 above the valve 25 and an upper washer 34 is interposed between the cotter pin 33 and the upper side of the valve 25. The rod 29 extends loosely through the opening 35 formed in the body plate I5 and is constantly urged upwardly to valve closing position by means of a spring 36. The spring 36 at its lower end bears against a washer 3'! engaging on the upper side of the plate I5 and the upper end of the spring 36 bears against an outwardly proiecting lug 38 carried by a depending arm 39. The arm 39 forms one leg of a U-shaped support 40, and the lu 38 is formed with an opening 4| through which the upper end of the rod 29 loosely engages.

- An upper cotter pin 42 is extended through the rod 29 and a washer 43 is interposed between the cotter pin 42 and the upper side of the lug 38. There are two of these U-shaped. members which are secured to the lower side of a movable handle or valve operator 44. The handle or valve operator M is slidably mounted on a pair of upstanding rods 45 having upper heads 46 and the rods or guide members 45 are secured by nuts 4! and it to the plate I5. The rods 45 are adapted to slidably engage through metal bushings 49 which are provided in the opposite end portions of the handle or operator 44.

In order to provide a means whereby the operstar 44 may be pressed downwardly, I have provided a lfixed handle 50 which is carried by a U- shaped support '51, being secured thereto by fastenin means 52. The opposite dependin legs of the inverted U-shaped support 5| are formed with outwardly extending flanges 53 which are secured beneath the upper nut 48 holding the guide bolts 45 on the plate IS. The U-shaped members 40 are secured to the handle or operator 44 by means of 'a pair of bolts or fastening members 54.

In the use and operation of this device, the handle 44 is grasped in one hand and moved downwardly by also grasping the stationary handle 58. This downward movement of the handle or valve operator 44 will swing the two valve members 25 downwardly to open position. The frame is thereupon extended into the mortar or mud to a point where the material will engage within the channels IS.

The movable handle 64 is then released so that the valve members 25 maybe swung upwardly to closed position, thereby trapping the mud or mortar in the chamber 55 formed by the channels I6. The frame is then disposed over the top of the tile T, the ends I I and I2 having the flanges 2-1 engaging on the top of the tile. The downwardly .fiared inner edges of the feet 22 provide a convenient means whereby the frame will be properly centered over the tile, and when the frame rests on top of the tile the movable handle '44 is depressed, forcing the valves 25 to open position and permitting the mud or mortar to drop onto the opposite lengthwise edges of the .tile T.

Witha mortar or mud applying tool as hereinbefore described, a, uniform quantity of material is applied to the upperedges of the tile and where the tile is formed with transversely extending walls, such walls may be suitably coated with mortar by a trowel or the like. It will also be understood that this tool may include the transverse channels and valves similar to the lengthwise valves 25 for applying the mortar to the transverse walls of the tile.

It is to be understood that the term tile as herein set forth "shall include bricks, hollow tile, terra cotta, concrete blocks or other masonary surfaces.

I do not mean to confine myself to the exact details of construction herein disclosed, but claim all variations falling within the purview of the appended claims.

What I claim is:

1. A mortar applying device comprising a frame formed of a horizontal plate and a pair of end plates depending from the ends of said first plate, said horizontal plate being formed with a pair of elongated parallel downwardly facing mortar receiving channels on said horizontal plate, a valve member for closing each channel at the open end thereof, means pivotally mounting said valve members below said horizontal plate at one side of said channels, a common operator for said valve members carried by said horizontal plate, each of said end plates being formed with downwardly divergent tapered cutouts within which a :tile is adapted to engage .to thereby correctly position said channels relative to the tile, and means normally urging said operator to hold said valve members in closed position whereby movement of said operator against the spring tension thereof will pivot said valves to open position for depositing mortar on the tile.

.2. VA mortar applying device comprising a frame including a horizontal plate and a pair of depending vertical end plates, downwardly open- ..ing channel members closed at the upper end thereof on said frame, valve members pivotally mounted on said frame for closing the open end .of said channels, and a common operator for said valve members, spring means constantly urging said valve members to channel closing position, each of said end plates formed with a downwardly divergent recess for engaging over the upper end of a tile on which the mortar is to be applied for positioning the frame on the tile.
