BRICKMAKINGr-MACHINE.

Specification of Letters Patent.

Patented May 3, 1910 Application filed May 14, 1909. Serial No. 496,077.

To all whom it may concern:

Be it known that I, GEORGE W. TAYLOR, a citizen of the United States, residing in the city and county of Denver and State of Colorado, have invented certain new and useful Improvements in Briokmaking Machines; and I do declare the following to be a full, clear, and eXact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in brick making machines adapted to be operated by hand, the construction being of such size and capacity that it may be advantageously operated by a single person.

It consists of a suitable upright framework upon which are slidably mounted standards carrying a press, containing a number of plungers corresponding with the number of bricks to be made by the mold at each operation. The mold is stationary upon the upright frame-work, and above the mold is mounted a receiver and shaper, which is hinged to the side of the mold and adapted to be thrown back when the mold is removed. The press is operated by a leverlike structure, carrying cams which regulate the vertical movement of the press. The latter is hinged or pivoted to vertically slidable members, and is adapted to be swung out of vertical alinement with the mold, to permit the filling of the latter by shoveling the brick material into the receiver and shaper.

Having briefly outlined my improved construction, I will proceed to describe the same in deail, reference being made to the accompanying drawing in which is illustrated an embodiment thereof.

In this drawing: Figure 1, is a front elevation of my improved machine. Fig. 2, is

a vertical section taken on the line 22,,

Fig. 1, viewed in the direction of the arrow, the press, however, being shown in its lowermost position, or after it has performed its pressing function. Fig. 3, is a side elevation of the structure, the operating lever, however, together with the press, being shown in a different relative position, or in the position which permits the filling of the molds. Fig. 4, is a vertical longitudinal section taken through the mold and the upper part of the press carrying the dies or plungers. Fig. 5, is a horizontal section taken on, the line 55, Fig. 1, looking downwardly. Fig. 6, is a fragmentary vertical section taken 011 the line 66, Fig. 1, viewed in the direction of the arrow, the parts being shown on a larger scale.

The same reference characters indicate the same parts in all the views.

Let the numeral 5 designate an upright frame-work, composed of two stationary vertical members 6, engaging longitudinal bottom beams 7, connected bycross beams 8. It is evident that this frame-work may be of any suitable construction. In order to give it the necessary strength, braces 9 and 10 are employed, the same being located on opposite sides of the stationary uprights. The braces 10 are provided with inclined upwardly projecting extensions 12, connected by a rod 13, which forms a rest for the pivoted uprights 14 of the press, when the latter is thrown to the position shown in full lines in Fig. 8, to permit the filling of the molds. The arms 14 are connected at their upper extremities by a cross bar 15, angle iron clips 16 being located at the corners for strengthening the structure.

Just below the bar 15, is located a cross beam 17, which is slotted as shown at 18, to receive bolts 19, which pass through upwardly projecting ears 20, connected with a horizontally disposed member 21, carrying dies or plungers 22, equal in number to the number of bricks which the mold 23 is adapted to form at each operation. The cross beam 17 is secured to the arms 14 by means of Ushaped clips 4, which are se cured to the ends of the beams 17 by bolts 3, and to the arms 14 by bolts 2. By virtue of the slots 18, the die-holding plate 21 is horizontally adjustable, whereby the dies may be brought into perfect vertical alinement with the corresponding compartments of the mold in which the bricks are to be formed.

The lower extremities of the arms 14 are pivotally connected with a rod 24, passing through vertically disposed slots 25 formed in the uprights 6 of the frame. This rod also passes through two parts 26 and 27, between which the extremities of the arms 14 are located. The parts 26 and 27 are adapted to slide freely in vertical ways 28 and 29 respectively, the said ways being formed in the uprights 6 on opposite sides of the frame. The parts 26 and 27 are secured to relatively long slidin members 30, which also engage ways 29 formed in the uprights 6.

.Mounted upon the uprights 6, and stationary therewith, is a transverse yoke 32, which straddles the uprights (S, and projects beyond the same at both ends. This yoke is composed of two longitudinal parallel members 33, whose extremities are connected as shown at 34, and provided with centrally located trunnions 35, upon which is pivotally mounted the operating lever 36, composed of two parallel arms 37, connected at the top by a handle 38. These arms 36 extend below the trunnions 35, as shown at 39, their lower extremities being connected with cams 45, which are carried by the lever arms, the latter being rigidly secured to the cam members. These cams, as shown in the drawing, are composed of vertically disposed plates or pieces 42, from whose lower edges flanges 48 extend outwardly, and form guides or supports for pins 40, mounted upon the upper extremities of depending members 41, located on opposite sides of the framework, and connected by rods 46, which pass through slots 25 formed in the uprights 6. The rods 46 are threaded at their outer extremities, and connected with the parts 41 by nuts 47. The inner portions of the pins 40 are provided with rollers, 48, which directly engage the flanges 43 of the cams.

Between the beams 6 and the depending members 41, anti-frictional rollers 49 and 50 are mounted upon the rods 46. These rollers form spacing sleeves between the members 45 and the vertically slidable parts 30; while the upper rollers 49 form anti-frictional bearings for the cams 45, during the operation of pressing the brick material into the molds. It must be understood that the rods 46 are fitted in openings formed in the vertically slidable members 30, whereby the last named members are caused to move vertically in harmony with the said rods.

To the upper edge of the top of the casing 52 of the mold, on one side, is hinged a sort of hopper 51, forming a receiver and shaper for the brick material. This device is thrown to the dotted line position in Fig. 3, when it is desired to remove the mold from the casing 52.

As shown in the drawing, the mold is composed of a bottom 53, provided with slots 54 located directly below the partitions separating the brick compartments 56. As shown in the drawing, the mold has a capacity for six bricks, having therefore six compartments 56. These partitions are connected with the vertical side members 57 of the mold. The slots 54 in the bottom of the mold are slightly wider than the partitions 55, thus leaving a restricted space for the escape of the brick material during the pressing operation. This is necessary in order that the bricks may be molded with perfect corners.

The receiving and shaping hopper is composed of an outer wall 58, whose inner surface is outwardly flared from the bottom upwardly, to facilitate the entrance of the brick material. This hopper device is provided with transverse partitions 59, which are equal in number to the inside partitions 55 of the mold, and located in alinement with the said partitions. The parts 59, however, are somewhat thicker than the partitions 55, and project slightly beyond the latter on both sides, thus compelling the brick material to strike the bottom of the mold before engaging the sides thereof. This is an important feature in a structure of this class. This peculiar construction also facilitates the proper formation of the upper corners of the bricks, since the dies when they descend are not allowed to come in direct contact with the upper surfaces of the bricks at their outer edges. Hence when the dies are lifted, the upper corners of the bricks cannot be injured or distorted by the possible sticking of the brick material to the dies. The upper edges of the hopper partitions 59, are curved, forming relatively sharp edges at the top to facilitate the entrance of the brick material to the mold compartments.

The mold casing is provided with a bottom 60, upon whose upper surface are located ribs or cleats (51, upon which the bot.- tom of the mold rests. This mold casing is open at one end, as shown at ($2, to permit the ready removal of the mold in an endwise direction. The mold casing is also transversely adjustable by means of bolts 63, which pass through openings formed in the bottom of the mold casing, and also through slots (34 formed in metal plates 65, which are secured to the tops of the uprights (3, and upon which the extremities of the mold casing rest. The tops of the uprights are provided with recesses (55, into which the threaded extremities of the bolts 63 project. These recesses are of sutficient size to permit a workman to apply nuts 66 to the extremities of the bolts, and loosen the latter at pleasure. If it is desired to adjust the mold casing for any reason, the same may be moved either forward or back by loosening the nuts 66, as will be readily understood, special reference being made to Fig. 6 of the drawing.

Secured to the front side of the mold casing, is a clip 67, whose upper extremity is recessed as shown at 68, to receive a hand piece 9 attached to the hopper member 51. The walls of the recess 70 are outwardly beveled from the bottom of the recess, to facilitate the entrance of the hand piece 69.

The clip 67 is secured to the mold case by a bolt 71, passing through a horizontal slot 72 formed in the case. By virtue of this construction, the clip is horizontally adjustable upon the case, in order to bring the recess 70 into positive alinement or register with the hand piece 69.

From the foregoing description, the use and operation of my improved machine will be readily understood. Assuming that the construction is in the position shown in Fig. 3. The brick material is shoveled into the hopper, passing thence into the compartments of the mold (see Fig. 6). The press structure containing the pivoted arms 14, is then raised to the vertical position, after which the lever 86 is operated by throwing the same toward the left, referring to Fig. 1, the movement being continued until the said lever occupies the position shown in Fig. 2. As the lever 36 is moved from the position shown in Fig. 3 toward the left, the movement of the cams 41 allows the press and its attachments to move vertically downwardly, since the cams are so shaped that during the said movement, the pins 44 resting upon the flanges 43 of the cams, are caused to travel farther from the pivotal center or fulcrum of the lever. This downward movement of the press continues by gravity, until the dies or plungers 22 are brought in contact with the brick material A (see Fig. 6). As soon as this occurs, and as the movement of the lever and its cams continues, the pins 44 will leave the upper surface of the flanges 48 of the cams, but the lower surfaces of these flanges will bear upon the anti-frictional rollers 49 of the upper rod 46, and the eccentricity of the cams is such that their action upon the rollers 49 forces the press downwardly, causing the dies which are in alinement with the brick compartments 56 of the press, to assume the position shown in Fig. 2. The bricks B are then properly formed, and as the movement of the lever 36 is reversed, the press is raised above the mold, and thrown to its original position (see Fig. 3). The receiving and shaping hopper member 51 is then opened, after which the mold may be removed from the case, and the operation heretofore described repeated.

Having thus described my invention, what I claim is:

1. In a brick making machine the combination with a stationary support, of members mounted to slide vertically upon the support, a press having arms pivotally connected with the slidable members, the said arms being provided with a plurality of perforations, whereby the press may be vertically adjusted upon the said arms, substantially as described.

2. A brick making machine consisting of a frame, a mold and mold casing mounted upon said frame, a hopper hinged to the mold casing, the hopper and mold having transverse partitions, the opposite sides of the partitions being arranged in vertical alinement, the partitions of the hopper being thicker than the mold partitions and overlapping the latter on opposite sides as means of forming a primary brick shaping chamber relatively smaller than the mold chamber, substantially as described.

3. A brick making machine comprising an upright frame composed of two separated standards having transversely alined vertical slots, members slidingly engaging the standards of the frame on opposite sides, a rod connecting the said slidable members, other rods passing through the slots in the uprights and projecting beyond the same, an operating device pivotally mounted on the frame and having separated parallel arms, cams attached to the lower extremities of the arms and having outwardly projecting flanges, pins adapted to engage the flanges of the cams, a holder upon which said pins are mounted, the said holder being connected with the rods passing through the uprights of the frame, substantially as described.

4. A brick making machine comprising an upright frame, including two separated vertically disposed, longitudinally slotted standards, members vertically slidable on the standards, means for imparting the vertical movement to the said members, a mold mounted on the frame, and a press having arms pivotally connected with the vertically slidable members, the latter being located on opposite sides of the frame, and means passing through the slots of the standards and connecting the vertically sliding members on the opposite sides of the frame, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

GEORGE 1V. TAYLOR.
