MACHINE FOR SURFACING BUILDING UNITS Filed Oct. 21, 1946 2 Sheets-Sheet 2 Patented Apr. 18, 1950 MACHINE FOR SURFACING BUILDING UNITS Foster W. King, Houston, Tex., assignor of onehalf to Jake E. Wiener, Houston, Tex.
Application October 21, 1946, Serial No. 704,547
2 Claims. (01. 25-1) This invention relates to a surfacing machine. An object of the present invention is to provide a machine of the character described specially designed for applying coating to building 7 units. It is another object of the present invention to provide a machine of the character described which will automatically apply and trowel the coating material automatically.
The invention also comprehends means for beveling the side margins of the coating as the same is applied to provide the desired joint between the building units when they are erected into a wall.
With the above and other objects in view the invention has particular relation to certain novel features of construction, operation and arrangement of parts, an example of which is given in this specification and illustrated in the accomunit showing the facing applied thereto.
Referring now more particularly to the drawings wherein like numerals of reference designate the same parts in each of the figures, the numerals I, I designate the front legs and tire numerals 2, 2 designate the rear legs of the supporting framework said legs being supported on a suitable base of any selected type.
Mounted in transversely aligned bearings in the front and rear legs are the front and rear transverse shafts 3 and 4, and fixed on these shafts between said legs are the front and rear drums 5 and 6. I
Operating over these drums there is an endless belt, or carrier, 1.
The shaft 3 may be driven by any selected power unit so as to rotate'the drum 5 to drive the belt I in the direction indicated by the arrows in Figure 1.
Between the drums 5 and 6 there is a table 8 which extends approximately from one drum to the other as shown in Figure 1 and which is somewhat wider than the belt, or carrier, I. This table is supported by the legs 9 spaced apart therealong on each side and these legs may be supported on a common base with the legs I and 2.
The upper run of the belt, or carrier, I moves along on this table 8, as indicated in Figures 1 and 3 and is thereby maintained in horizontal position against sagging.
The building units In to be surfaced are de livered onto the forward, or feed, end of the belt,
or carrier, and move along with it to the delivery end, the main load of said unit, however, during the process of surfacing being supported by the table 8.
On opposite sides of the belt, or carrier, I and converging upwardly are the guide plates II, II. These guide plates accurately guide the units as they move along the table. The lower margins of the guide plates II are hinged to move, on longitudinal axes, to the inner margins of the side anchor plates I2, I2. These anchor plates are arranged one on each side of the table and are spaced above, and anchored to, the table by means of the series of upright bolts I3, I3 which are arranged in pairs that are spaced apart from end to end of said anchor plates, as shown more clearly in Figures 2 and 3. These bolts I3 are secured to the table, at their lower ends, and their upper ends extend through the anchor plates and are secured thereto by clamp nuts, as I4, I4, so that the anchor plates may be adjusted as desired.
Upstanding from the anchor plate, and spaced apart therealong on each side, are the standards I5 whose upper ends are provided with bearings to receive the guide rods I6.
The inner ends of the guide rods I6 are pivotally connected to the guide plates I I and screwed onto their outer ends are the adjustable stops I1.
Surrounding the guide rods IB and interposed between the corresponding standards I5 and the guide plates II are the strong coil springs I8.
The inner margins of the anchor plates I2 are spaced apart a distance somewhat greater than the transverse diameter of the building unit to be surfaced and therefore the guide plates I I converge upwardly and contact the building unit being surfaced only at the upper corners thereof being held in yielding contact therewith by the springs I8. The upper margins of the guide plates I I extend slightly above the building unit passing between said plates, as is shown in Figure 3 and for a purpose to be hereinafter explained.
There is another set of standards arranged in pairs, the standards of the respective pairs being indicated by the numerals l9, I9; 20, 2n; 2!, 2|; and 22, 22. The standards of the respective pairs are arranged one on each side of the machine, as shown in Figures 1 and 2.
The upper ends of these standards are provided with transversely aligned bearings and between the standard of the respective pairs are the trowels 23, 24, 25 and. 26. The forward margins of the trowels are provided with laterally extended pintles, such as 21 which are rotatable in the corresponding bearings. The rear margin of the trowel 26 is held spaced slightly above the upper margin of the guide plates II by the upstanding stops 28, 28 which are shown more accurately in Figures 1 and 3 but the rear margins of the other trowels rest on theupper margins of said guide plates. They are held in yielding contact with said upper margin of the side plates, and stops 28, by the pull springs 29, 29; 30, 30'; 3|, 3i; and 32, 32. The upper ends of these pull springs are attached to the corresponding ends of the trowels and their lower ends are attached to the outer sides of the guide plates H, as shown in Figures 1 and 3. The forward end of one of the anchor plates [2 is widened laterally and upstanding from this laterally widened portion 33 there are the legs 34, 34 and mounted to rotate in longitudinally aligned bearings in the upper ends of these legs there is a shaft 35. Fixed on the rear end of this shaft there is a disc 31. A connecting rod 38 is pivotally connected, at one end, to the adjacent pintle of the trowel 2B and is pivotally connected, at its other end, to the disc 31 at an eccentric point so that as the disc 31 rotates it will oscillate the trowel 26 transversely with respect to the building block being treated.
The pulley 3% and shaft 35 are driven from a belt 39 which operates over the pulley 35 and also over a pulley 50 which is fixed on the forward end of a longitudinal shaft 4!. This shaft is mounted to rotate in suitable hearings in the framework and fixed on its rear end is a pulley 42 over which a belt 43 operates, said belt being driven from a pulley 44 which is' fixed on the main drive shaft 3.
The surfacing material may be applied to the building units l in any preferred manner. It is contemplated that a special type of surfacing material will be applied which will not only render the treated surface of the unit water proof but will also impart to the unit a smooth, glazed surface of any selected tint.
It is preferred, however, to deliver the surfacing material automatically and continuously to the units as they pass through the machine. For that purpose a container, such as 45 has been provided which is supported above the forward, or feed, end of the machine. It is preferably cylindrical in shape. Within, and closing, the container there is a piston 46 which is fixed to an externally threaded piston rod 41. Fixed to the open end of the container 65 there is a suitable bracket '38 within which there is to swivel a nut ts which is threaded onto the piston rod 47. The
outer end of this nut is formed into a pulley B which is in alignment with a corresponding pulley 5i which is fixed on the shaft M. A belt 52 operates over the pulleys 50, 5| and transmits rotation to the former from the latter. As the nut 49 is thus rotated the piston 46 will be moved inwardly against the material filling the container 45.
Leading from the other end of the container there is a flexible hose 53 which terminates in a laterally widened discharge nozzle 54 which is mounted slightly above the top surface of the blocks moving along the carrier 1.
The surfacing material will thus be fed onto the top surface of the building units ID in ad Vance of the trowel 26 and this trowel will distribute the finishing material evenly on the sur facing material and this finishing material will be successively moved and pressed against the units by the finishing trowels 25, 24 and 23 and as the units are discharged the surfacing process will be completed.
The top surfaces of the building units should be moistened before the finishing material is applied thereto and this material is of such composition and nature that it will unite with the material of the building units and will permanently adhere thereto.
It may be here stated that the bracket 68' is detachable from the container 4'5 so that when it is desired to refill the container the belt 52 may be removed from the pulley 58 and the last mentioned pulley turned in the reverse direction to withdraw the piston 46 to starting position and the brackets 68 may then be removed to permit a refilling of the container and then reattached to continue the process as above explained.
It is to be further understood that if desired the container 45 may be supported in a vertical position rather than horizontal as shown and. gravity thus used to feed, or assist in filling the surfacing material to thesurfaces of the building units.
The drawings and description are illustrative merely while the broad principle of the invention will be defined by the appended claims.
What I claim is:
l. A surfacing machine for surfacing building units, and the like, comprising, an endless belt forming a carrier, means for driving the carrier, plate-like elements spaced apart one on each side of the carrier, a plurality of trowels above the plates arranged to trowel surfacing material applied to the upper faces of the units and means for oscillating one of said trowels transversely.
2. A surfacing machine for surfacing building units, and the like, comprising, a carrier for supporting said units, means for driving the carrier, guide plates spaced apart one on each side of the carrier and which converge upwardly and whose upper margins extend above the top surfaces of the units on the carrier, a transverse trowel above the plates arranged to trowel surfacing material applied to said upper surface and means for oscillating the trowel.
