T all. whom it may concern."

Be it known that I, FRANK HELM, a citizen of the United States,`residing at Traverse Ci ty,

in the countyof Grand Traverse and State of Michigan, have invented a new and useful Machine for Making Pressed Brick, of wliichthe following is a specification.

Aimprove the construction lof machines for The invention relates to improvements in machines for making pressed brick.

The object of the present invention is to making pressed brick and to provide a simple and comparatively inexpensive brick-machine of this character capableof molding and conipressing clay, cement, or analogous material into the desired form and adapted to produce a number of bricks at each operation of the machine.

A further object of the invention is to pro-V vide a-brick-making machine to whiclrthe c`ement, clay, or other material may be conveniently delivered and which aftersthe bricks have been' molded and compressed will'enable the same to be readily removed from it.'-

Another object of the invention is to provide a brickemach'ine which will be adapted to ornament the bricks and which will enable the latterA to 'I be removed without injuring portion, size, and minor details of construction within the scope of the claims may be resorted to without departing from the spirit or sacrificing any of the advantages of the in- In the drawings,Figure l is a side elevation, partly in section, ofy a brick-machine con-1 structed in accordance with this invention, the parts being in position to support a box ofcement or other material in position for feeding the machine'. Fig. 2 is a transverse sectional view of the same, the verticallymovable mold-carryin g frame being depressed to carry the moldy into the cement box or re' lon the'line 5 5 of Fig; 1.

A. ceptacle to fill the cells or compartments with material.- Fig. 3 is a similar view, the table being raised vfor compressing the material. Fig. 4 isa vertical longitudinal sectional View, both levers being swung upward to raise the mold 'and to lower the table or platform and lthe brick being exposed for removal from the machine'. Fig. 5 is a horizontal sectional View Fig. 6 is a detail perspective view of one of the pivoted'automatically-operated supports. Fig. 7 is an enlarged detail sectional viewof one side of the mold, illustrating the construction of the Lhingedgate and the' means for automatically opening-the saine and forlocking. the gate. Figp8 is avdetail view illustrating the manner 'of guiding the vertically-movable cross-head which carries thetable or platform.

Like numerals of reference designate corresponding parts in all the figures ofthe drawings.

1 designates a main ,frame provided with oppositely-inclined sides or standards 2, secured to'and rising from the ends ofa base 3 andv connected at their upper terminals bya ih'orizontal cross-piece 4. Mounted upon the main frame is a supplemental guiding-frame composed of uprights fand a connecting top Vbar 6. The cross-piece 4 and the top bar 6 are provided with registering or'alined perforations7 and 8, which receive parallel rods or bars 9 vof a vertically-movable frame. The bars or rods 9, which are preferably rounded, as shown, are connected at their upper ends by a cross-head l() and at their lower ends by a mold ll, thelatter being' located at a point below the top piece 4'of the body portion of the frame of the brick-machine.

The mold l1 consists of an oblong box provided with' a series of transverse' partitions 12, preferably constructed of metal and having their lower edges 13 beveled or sharpenedto enable the partitions to readily cut their way through a mass of ceinentfor other Inaterial, as hereinafter explained. of a width equal to the length of a brick, and the cells or compartments formed by the partitions are of a width equaly to the thickness of a brick. The mold is provided at one side with a hinged door or section 14, provided yat The mold isv TOO its upper edge with perforated ears 15, arranged adjacent to corresponding ears 16 of the mold and receiving removable pivots 17, whereby the hinged section or door may be readily removed when desired. The perforated ears of the hinged section or door are preferably formed by cleats or ribs, which project beyond the upper edge of the door or section, as shown. rl`he door or section may be provided, as indicated in the accompanying drawings, with depressions 18 to form projecting panels on the ends of the bricks, and corresponding panels are formed on the upper edges of the bricks by plungers 19, which are provided with recesses or depressions 20.

The hinged section or door and the plungers may be provided with projections to form depressed panels in the bricks, or any other desired ornamentation may be provided. rlhe hinged section or door and the plungers may be constructed to form a rock-face on the front ends and upper edges of the bricks, and after the bricks have been compressed, as hereinafter explained, the hinged section or door is released and is automatically swung outward or open by a spring 21, arranged in 'an upright position at the front of the mold and secured at its upper end to the same and having its lower end engaging an eye 22 of the hinged section or door. The ends of the mold 'are provided with projecting arms 23, having bearings for the reception of journals 24 of a cam 25. The cam 25, which is provided with a central handle or operating-arm 26, is arranged to engage cleats 27 of the door or section of the mold. When the operating arm or handle 26 is swung downward, the cam is carried into engagement with the hinged door or section, andthe latter is held firmly closed while the bricksare being molded. When it is desired to release the bricks, the operating arm or handle is swung upward and the spring automatically throws the hinged door or section outward beyond the ornamented end faces of the bricks, thereby permitting the mold to be raised from the bricks without marring or otherwise injuring the said ornamented end faces.

The plungers 19, which are stationary, are vertical and are secured at their upper ends to the top cross-piece 4 of the main frame of the machine and are provided at their lower ends with suitable heads 29, which correspond in shape and size to the cells or compartments of the mold. These plungers, which are stationary with relation to the mold and to a lower vertically-movable cross-head 30, are preferably secured to the top of the main frame Vof the brick-machine by means of a detachable plate or board 31, whereby the plungers are adapted to be removed for enabling another set of plungers having a different design to be applied to the brick-machine.

The vertically-movable cross-head 30, which is provided at its ends with V-shaped notches 32 and 33, is engaged by guides 34 and 35 of triangular shape secured to the inner inclined faces of the ends 2 of the main frame and provided with vertical guiding edges, which are oppositely beveled to conform to the configuration of the notches 32 and 3i) of the lower vertically-movable crosshead. ',lhe lower face of the cross-head 30 and the upper face of the base 3 of the main frame are provided with bearing-recesses 3G and 37, detachably receiving toggle-levers 38, arranged in pairs, as clearly shown in Figs. l and 2. The members of each pair are connected by a horizontal pivot, and the latter are connected by a link 39. One of the pivots of the toggle-levers is connected by a link or bar-1 0 with a lower operating-lever 41, having one end 42 bifurcated and fulcrumcd on one end of the main frame of the brick-machine near the bottom thereof between suitable bearings 43. The end or standard upon which the lever 42 is fulcrumed is provided with a slot or opening to receive the connecting bar or link 40, which is pivoted at its outer end by a pin 44 or other suitable fastening device in the bifurcation of the lower operating-lever. The toggleslevers preferably consist of two sides and an intermediate connecting portion, as clearly shown in Fig. 2, and the inner end of the connecting bar or link 40 is enlarged and extends across thespace between the sides ofthe adjacent toggle-levers. lVlicn the lower operating-lever 41 is swung downward from the position illustrated in Fig. 1 of the drawings, the toggle-levers will be straightened and'the lower vertically-movable cross-hezul 30 will be elevated, and when the lower level' 4l is swung upward the lower cross-head will be moved downward.

The lower cross-head is provided with a table or platform 45, and it has mounted upon it pivoted supports 46, located at the ends of the table or platform, which extends longitudinally of the cross-head 30. The pivoted supports are composed of two sides and a counecting portion provided with an upwardlyextending inclined arm 47. The sides are enlarged at their lower ends to forni feet and are pivoted at the outer portions thereof to transverse cleats 48 by pins 49 or other suitable fastening devices. '.l`he upper ends of the sides form shoulders 50,`arranged to support a box 51, which is adapted to contain the cement, clay, or other material from which the bricks are molded. The box, which is open at the bottom, has inwardly-exteiuling bottom flanges 52, provided with concave upper faces forming projecting edges 5?, which are adapted to lit against the lower face of a removable bottom board 54, whereby a tight joint is effected. The box with its removable bottom in position in the bottom flanges is iilled with cementor other material, which is scraped ofi' level with the upper edges of the box, and the latter is then placed IOO llO

ings.

upon the supports 46 in the position. illustrated in Fig. l of the accompanying draw- The opening within the bottom Iianges of the boxcorrcsponds in size to the `table or platform which projects into the opening, as shown. rIhe mold is then moved downward to the position indicated in Fig. 2 of the drawings by means of'an upper operating-lever 55. bifurcatedto straddle the upper supplemental `or guide frame and fulcrumed at its inner end on the same at one side thereof..l

- The other end of the lever 55 is shaped intoa handle, and the sides formed by the bifurcation are connected with the top cross head or piece l() by links 56. Instead, however, of employing operating-levers for actuating the vertically-movable frame and the lower vertically-movable cross-head any other suitable means may be employed, and a suitable motive power may be provided foractuating these parts.

The downward movement of the moldwithin the box or receptaclesupplies the brick cells or compartments with concrete or other material, and the lower cross-head is then raised by swlnglng the lower operating-lever downward. The upward movement of the lower cross-head carries the material against the stationary pluugers, and the bricks are molded and firmly compressed. This upward movementalso carries the inclined arms 47 of the pivoted supports into engagement with approximately L-shaped trips 57, .fixed to the inner faces of the sides or standards 2 and arranged in the path of the saidv arms 47. The supports are drawn outward by the trips, and

the box 'is caused to drop to the position illusy removable bottom 54of the box 5l.
