Application filed Iieloruary 15, 1910. Serial No. 543,983. 1

To all whom it may concern:

Be it known that I, ARTHUR STANLEY BA- CON,:., a citizen of the United States, and resident of Oklahoma cit in the county of Oklahoma and State of klahoma, have invented certain new and useful Improvements in Brick-Machines, of which the following is a specification.

My invention is an improvement in brick machines and. consists in certain novel constructions and combinations of parts hereinafter described and claimed.

The object of the invention is to provide a machine of the character specified, especially adapted for the making of cement brick, which will receive the plastic material and press it into shape, and having means for expeditiously removing the pressed brick onto a pallet for removal from the machine.

Referring to the drawings forming a part hereof, Figure 1 is a side view of the improvement, Fig. 2 is a section on the line 2-2 of Fig. 1, Fig. 3 is a section on the line 33 of Fig. 1, Fig. 4 is a sectional view of. a portion of the mechanism shown in Fig. 2, with the dies open, Fig. 5 is a bottom plan View of a section of the lower die, Fig.

6 is a section on the line 66 of Fig. 5. Fig.

7 is a plan View of the apron, Fig. 8 is a similar view of the bottom die, and Fig. 9 is a vertical section at right-angles toiFig. 2.

The embodiment of theinvention shown in the drawings consists of a framework composed of uprights 1 arranged in pairs, one pair at each end of the frame, and the members of each pair are connected at their tops by a cross bar 2, and each is provided with a foot 3, bolted toan I-shaped base bar 4: by bolts 5. 7

The cross bar 2 is provided at its center with a' rectangular opening -6 and a top bar 7 is provided with reduced ends 8, which are received in the openings, as shown in Fig. 2. The length of the opening 6 is greater than the depth of the reduced end of the bar, and a set screw 9 is threaded through the cross bar, and engages the lower face of the end of the top bar. The base bars are also connected near each side of the frame by. a bottom bar 10 whose reduced ends 11 rest on the base bar, and are secured thereto by cap screws 12. The said bottom bars form part of a grid or grating, being connected at spaced intervals by cross bars 13, which extend beyond the frame at one side as at 14, and form a slideway for a purpose to be presently described.

Above the extendedends 14 of the cross bars, are arranged horizontal bracket arms 15 extending from the uprights and a hop,- per 16 is supported on the arms, being secured to the frame by clips 17. Another pair of bracket arms 18 extend from the uprights at the opposite side of the frame,

and each arm isprovided on its inner face with a rest or guideway '19, and at approximately its center with a recess 20 on its upper face.

A bottom die composed of a plurality of similar sections 21 rests upon the grid or slideway, each'section consisting of a substantially box-shaped structure arranged bottom upward, the upper surface 22 being flat and the sides 23 forming a support engaging the grid. At the center of each side wall, each section is also provided with a notch 24:, and a bar 25 passes through the notches, which are in alinement.

Each notch is enlarged transversely near the edge of the side wall, as shown at 26, and a cross bar 27 is arranged beneath the bar 25, and secured thereto, the ends of the cross bars engaging in the ends of the enlargements. A resilient bar 28 is secured to each end of the supporting bar 25, by a cap screw 29, and the free end of each resilient bar is provided with a head 30, and

shoulders 30 and 30 are formed between the head and the bar on each side of the said bar. The shoulder 30 is adapted to engage above theupper edge of a box, to be presently described, which encircles the dies.

The upper die 31 is in the shape of a plate, provided on its upper face near each end with pairs of spaced lugs 32, and on its lower face with spaced parallel transverse grooves 33, and each end of the plate is provided with an outwardly extending lug 34 near its upper face.

A. resilient bar 35 is secured to each of the lugs 34:, by a cap screw 36, and the lower free end of each bar is provided with an angularportion or hook 37, for engaging ghe shoulder 30 on the bar 28 of the lower A box 38 rectangular in shape encircles the dies, and the-said box is provided at spaced intervals with transverse parallel division or' partition plates 39 which fit in the grooves 33, and in the spaces 40' between the sections of the lower dies. The box is also provided at each end with a flange 41 extending laterally from the end of the box, and provided with an opening 41 for the bar 35, the flange moves in the grooves 19 of cross bars 68 on the frame.

A rod 42 is threaded into the upper face of the plate 31 at each end, and the upper end of the rod moves in a sleeve 43, on a bracket 44, secured to plates 45, extending between the uprights, by bolts 46, and the rods act as guides for the die plate in its vertical movement.

Other rods 47 provided at each end with a head 48 are connected with the die plate, one of the heads of each rod being received between a pair of lugs 32, and pivoted there to by a pivot pin 49, whose ends are engaged by cotter pins 50, to retain the pins in place.

The upper heads of the rods 47 are received between spaced ears 51, on the lower ends of rods 52, whose upper ends are formed into loops 53 encircling the top bar 7 A pivot pin 54 is passed through the ears and the head, pivotally connecting the rods, and the ends of each pivot pin are extended to engage openings in the arms 55 of a yoke 56, extending horizontally, the parts being held in place by cotter pins 57 passing through the ends of the pivot pins.

The body portion of each yoke is provided with a sectional bearing 55 in which is journaled a crank arm 59, on a crank shaft 60, journaled transversely of the frame. One end of the crank shaft is provided with a laterally extending lever 61 whereby to oscillate the shaft, the lever extending toward the front of the machine, as shown in Fig. 1.

A rock shaft 62 is journaled at the front of the frame, in sectional bearings 63 on the uprights, the shaft having an arm 66, near each end between the uprights, and an arm 65 outside of the uprights at one end and extending toward the front of the machine. The arms 66 extend downwardly and for: wardly to a pivotal connection with one end of links 67, extending forwardly from the box inclosing the dies and pivoted thereto at their opposite ends as at 67 Each pair of rods 4752 form a toggle lever which is broken and straightened by the movement of the crank shaft, the levers acting at one end against the upper die, and at the other against the top bar 7.

In the operation of the machine, the plastic mixture is placed in the hopper. The guideways or grooves 19 in the arms 18 are in alinement with grooves 19 extending across the frame in bars 68 and underneath the hopper in the bracket arms 15, so that the box may be moved from beneath the hopper to the front of the frame. with the box beneath the hopper as shown in Fig. 9 the plastic material passes from the hopper into the molds formed by the box 38 and die .neath the upper die section 31.

sections 21. When the molds are filled, the shaft 62 is operated to move the box 38, apron 75 and die sections 21 forwardly be- The lever 61 is now operated to straighten the toggles 4752, thus moving the upper die downwardly and compressing the plastic mixture in the molds. As the upper die moves downwardly, the hooks 37 of the bars 35 engage beneath the shoulders 30 of the heads 30. The shaft 60 is then operated to break the toggles 4752, moving the upper die 31 upwardly and the bar 25 with the die sections 21 supported thereby is lifted with the upper die. The said die sections 21 move upwardly between the partitions 39 and lift the blocks 7 (3 above the upper edge of the box 38 and partitions 39. lVhen the said bar 25 has been lifted to its highest position, the shoulders 30 of the bars 28 engage over the upper edge of the box, thus locking the die sections 21 in the compartments formed between the box 38 and partition 39 and with the upper surface of the die sections level with the upper edge of the box. The pallet 71 has meanwhile been placed on the arms 77, each of which arms is provided at its outer end with an upwardly extending lug 78 for engaging the edge of the pallet to cause the said pallet to move with the apron and molds. The shaft 62 is again operated to move the apron, box and die sections rearwardly, and the blocks 76 engage on their rear ends the plate 69 and are held from further rearward movement with the apron. As the apron continues its rearward movement, the pallet 77 is moved beneath the blocks as indicated in Fig. 9. The shoulders 30 are now disengaged from the upper edges of the box 38 in any suitable manner, permitting the bar 25 and the die sections 21 supported thereby to drop into the position shown in Fig. 9 ready to receive another charge of plastic material. When the apron again moves forwardly, the pallet 77, blocks 76 are moved into the position shown in dotted lines in the arms 18. The pallet and blocks may then be removed manually, the recess 20 permitting the hands of the operator to engage beneath the pallet. The toggle levers are meanwhile broken, so that the upper die plate is in elevated position. WVhen the box is in position in the frame, the shaft is oscillated, to straighten the toggle levers, thus bringing the upper plate onto the lower with an immense pressure, thoroughly tamping the mixture into the molds formed by the upper and lower plates, the box and its partitions. As the upper plate descends, the hook 37 engages the shoulder 30, and the hook and shoulder lock with each other, and the box and plates are firmly held in this position. It will be observed that the outer faces of the heads 30 are beveled so that the hook and shoulder may be easily separated when it is necessary. While the die plates are locked together as above described, the toggle levers are again broken, and the molds are lifted into position level with the pallet 71 which is supported in the guideways of the bracket arms 18. The bricks 76 are now transferred to the pallet, which may be removed from the machine by hand, the recesses 20 permitting access to the bottom of the pallet from the sides. The wear of the toggle mechanism may be compensated for by the set screws 9. It will be evident that the lower die plate may be considered as a plate having transverse grooves to receive the partitions, and that the box is in effect a rectangular frame.

An apron 75 is mounted to slide transversely of the machine beneath the hopper, to close the bottom of the same when the lower dies are moved beneath the upper dies v(Fig. 7) and the said apron is connected with the upper edge of the box 38 and extends rearwardly therefrom. When the box is moved beneath the hopper, the apron is moved rearwardly from under the same, and when the box is moved forwardly the apron closes the bottom of the hopper.

A plate 69 is arranged across the machine at the front of the hopper, (Fig. 1) to support the brick against rearward movement when the pallet is moved under, them.

The box 88 which encircles the lower dies is locked in position around the dies by the engagement of the shoulder 3O with the upper edge of the said box. The arms 77 extending forwardly from the apron 7 5 are adapted to receive the pallet and support the same.
