spaliatioa iS a mimetica-impart of my copending application Serial No. 287,954, led lune 14, 19H63 and entitled Mortar Dispenser, now abandoned. Y

This invention relates to masonry construction, V':llld deals more particularly with a device for dispensing a rlbbon or layer of mortar on a building block 'orvblockrs being laid .in a horizantal ufs@ af val- )ne object o f the present invention is to` provide a mortar dispenser of the above nature which may be used to extrude a continuous thin ylayer or ribbon of Wet mortar upon a row of cinder bloclrs or other similar building blocks preparatory to placing the next row of the blocks thereon. i l I A further object of this invention is to provide a mortar dispenser which includes a provision for readily controlling the thickness of the mortar ribbon extruded therefrom and with which it is impossible to produce a mortar ribbon o t less than a predetermined thickness.

A `still further object of this invention is to provide a device of the above character which -is attractive in appearance, readily useable by an inexperienced person, and relatively inexpensive to manufacture.

Other objects and advantages of theinvention will be apparent from the following description and from the drawings forming a part hereof.

'Ihedrawingsv show oneV embodiment of the device comprising the invention and such embodiment will be desciibedjbut it will be understood that various changes may be made from the c :onstruction disclosed, and that the drawings and description are not to be construed as defining or limiting the scope of the invention, the claimsy forming a part of this speiication being relied upon for that purpose.

( )f the drawings:

FIG. 1 is a perspective view showing a mortar dispenser embodying the present invention.

FIG. 2 is a vertical sectional view taken through the mortar dispenser of FIG. l, the dispenser plate in this view bein g shown in its raised positionl Y FG. 3 is a vertical sectional view similar to FIG 2, but showing the dispenser plate in an inclined position.

FG. 4 is a rvertical sectional view similai to FIG. 2, but showing the dispenser plate in its fully lowered position.

FlG. j is a perspective view on a reduced scale showing the mortar dispenser of FIG. 1 in use.

Referring now to the drawings, and first considering FGS 1 and 2', a mortar dispenser embodying the present invention is shown generally by the reference numeral 1%. The basic components of the dispenser are two horizontally elongated and vertically extending

side walls

12, 12 between which is received a dispenser plate 14 having a length substantially equalV to that` of the side walls. In theillustrated case, the side Walls 1 2, 12 c onsist of the side walls of a U-shaped channel member whichl in addition to., the side walls includes a horizontal top wall 16. A handle 15 is secured` to the topwall 115 of the channel member and includes a generally horizontail grip portion 24B, and two vertically extending end portions 2:2., Z2 The two. endportions 2,2., 2.2,. extend downwardly beyond the grip portion 2,0 so as to provide a finger opening 24 located between the grip portion 20 the top wall 145, and between the two end portions 22 2210i the handle.

i As shown bestl in FiG. 2, each handle end portion 22 ICC has a vertical opening passing therethrough, each such opening including a smaller diametered portion 26 at the upper end thereof and a larger diametered portion 28 which is located below the smaller diametered portion 26 and which extends downwardly fully to the top wall 16 of the channel member. As explained in more'v detail hereinafter, the larger diametered portion 2S of each vertical opening in the handle'13`comprises a spring chamber and is preferably lined with a sleeve 36 of metal or other wearresistant material; The top wall 16 or the channel member also includes two openings 32 32 each of which is aligned with a respective one of the openings in the handle 18. The handle v1? maybe made of wood or plastic or other suitable material andrin theillustrated example is fastened to the top wall 16 of the channel member by two flat-

headed screws

35, 35 each passing upwardly through openings in the top Wall into threaded engagement with a respective one of the

end portions

22, 22 ofthe handle.

' Passing through the vertical openings in the end portions of the handle and through the

openings

32, 32 in the top wall 1 6 are two

posts

34, 34 whichA at their lower end are fixed to the dispenser plate 14 and `which at their upper end are fixed to a squeeze member 36 which extends between the posts at a location spaced above the handle 1d. The posts may be iixed to the dispenser plate 14 and to the squeeze member 36 in various different ways, but as shown in FiG. 2, each post at its lower end includes a reduced diameter threaded portion 33 which is threaded into a corresponding threaded openingvin the dispenser plate. At its upper end, each post includes another reduced diameter portion 4d which passes through the squeeze member S and which at its outer end threadably receives a cap nut 42 for retaining the squeeze plate in place on the threaded portion d@ and against the shoulder separating the reduced diameter portion d@ from the remainder of the post.

Biasing means are provided for urging the dispenser plate 14, the

posts

34, 34 and the squeeze member 36 to the raised position as shown in FG. 2. In the illustrated embodiment, this biasing means comprises a radial flange 44V formed on each post 34 and located in the associated spring chamber 2S. Each flange 44 provides a downwardly facing spring seat and cooperating with each of these spring seats is another upwardly facing spring seat whi. h is dened by that portion of the top wall 16 surrounding the associated opening 32. Between these two spring seats is a helical compression spring 46 which surrounds the portion of the associated post located below the `flange 44. The flange d4. may be formed integralv with the remainder of the post 34 or may comprise a washer xed to the post as by press iitting--or welding. The. two springs 46, lo urge the dispenser plate 14, the two

posts

34, 34 and the squeeze member 36 to. the position shown in FXG. Z whereat further upward movement is prevented by engagement or the dispenser plate withthe topwa-ll 16.

By referring to ElGS. 2, .9,A and '4, lit will. be noted' that the openings in the handle 1S and. top wall' 1'61 through which the posts 34, 34: pass are ofI substantially larger diameter than the posts so that the posts. may be tilted relative tothevertical axes of' the openings in the handle, as shown for examplein FG. 3. 'Ihistilting o the posts 3d, 3A is obtained by pressing` down with. a` greater force on one end of' the squeeze plate 36'. thanonV the other end and results inthe dispensing plate 1A beingA inclined relative to the side walls 12,12zas shown B1G. 3.. In FIG. 3, the dispensing plate is inclinedginsueh a direction that the right-hand end ofthe plate is at a. lower eleva.- tion that theleft-hand end, however, it willrbe understood that the inclination could be-reversed if desired. ln use, a charge of mortar is receivedy between the side walls.y 12,

amasar 12 and by tilting the dispensing plate so that the trailing end thereof is at a height above the lower downwardly facing surfaces 5t), 50 equal to the desired thickness of the ribbon of mortar to be dispensed, the operator may control the thickness of the mortar ribbon. That is, in use the dispenser plate is rst tilted by Vpushing down on one end of the squeeze plate 36 until the trailing end of the dispenser plate 14 is at a height corresponding to the desired thickness of the .mortar ribbon. The dispenser is thenv moved forwardly by sliding the lowered downwardly facing

surfaces

50, 50 over the cinder block. As this forward motion takes place, the inclination of the dispenser ,plateexerts a wedging action on the mortar causing the same to be extruded from the trailing end of the dispenser between the cinder block and the trailing cmd of the dispenser plate. As the quantity of the mortar in the dispenser is reduced, the forward end of the squeeze member 36 is squeezed further downwardly relative to the handle 18 until eventually it and the dispenser plate 14 reach the horizontal position shown in FIG. 4. The position of the dispenser plate shown in FIG. 4 is such that it is spaced a substantial distancevabove'the

lower surfaces

50, 50 of the side walls and the distance between these surfaces and the dispenser plate corresponds to the minimum thickness of the mortar ribbon capable of being dispensed by the dispenser. This position is determined by the design of the

springs

46, 46 which are fully compressed yat this time. That is, the springs 46, 45 together with the

flanges

44, 44 and the top wall 15 cornprise a means for limiting the downward movement of the dispenser plate to the position shown in FIG. 4. Y

Guide means may also be provided on the dispenser as an aid in locating the dispensed mortar ribbon close to the edge of the building blocks on which it is laid. Referring to FIG. l, this guide means in the illustrated construction comprises'two small plates 52, 52 which are fastened to the outboard side of one of the side walls 12, y12 and which extend below the lower surface 50 of said side wall.

Each `guide plate 52 therefor provides a vertical guide surface 54 which extends below the downwardly facing

surfaces

50, 50. As shown in FIG. 5, the dispenser 10 in use is placed so that the downwardly facing

side wall surfaces

50, 50, rest against the upwardly facing surfaces of the building blocks 56, 56 so that the guide surfaces of the guide plates 52, 52 ride against the associated vertical surface of the block. The, guide surfaces therefore locate the dispenser so that the dispensed mortar ribbon 53 is located, as desired, adjacent the edge of thev blocks. It

will, of course, also be understood thatinuse the disl penser is manipulated by grasping the handle 13 and squeeze member 36 in one hand of the user, the lingers of the hand being inserted in the handle opening 24 and the palm of the hand resting against the squeeze member 36 andbeing used to apply a squeezing pressure to the squeeze member as the dispenser is moved forwardly by the hand.
