- :amok-MAcame.

\ The Schedule referred to-in these Letters Patent and making part of the same.

To all whom may concern: l

Be it known ,that I, J Aco COOKE, of the town of Money, county of Lycoming, and/State ot'Pennsylva nia, have invented certain new and useful Improvements in Brick-Making Machines, and I do hereby declare the following to be' a full, clear, and exact description of the same,`and its` manner Ot' operation,

reference being had to the accompanying drawings, and the letters of reference marked thereon.

1n all the figures, like letters or ligures designate like parts. l

In the drawings- Figureliepresents a side elevation of the machine.'

Figure 2 is a pla-u or .top view ofthe machine. Figure 3 is a front elevation. v Figures 4 and 5 are views of the moulds, showing their manner ot construction and connection together. 1n all the figures in which it occurs, A represents the frame ofthe machine. It is intended .tobe made of wood of a suitable quality, and is so proportioned as to have the proper stability andstrength.

Strictly speaking, the letter A indicates the sides of the trame-work.

They arev connected together by the cross-pieces 6 7, that are rigidly attached to the sides A, at the points indicated in tig. 1.

Upon these cross-connecting pieces 6 7, a suitable bed or tloor is aixed. u

Upon this bed the rails or supporting-strips :t :c are laid, and iirmly attached thereto. Said strips are laid .parallel to each other, as well as to the sides ot' the frame. v t

Upon theserails the moulds m m m, Ste., rest when they are in position in the machine.

Said moulds are constructed of'wood, or other suitf able nvxaterial, and are given the form substantially as shown in tig. 5.

As will he observed, the clay-receiving cavities i'or the formation or shaping of the brick, are made in the upper side of the mould. Said cavities are herein shown as numbering four, though` any convenient number may be used. 'lhey are made parallel to each other, a proper space intervening between them, thus leaving dividing-walls standing to separate them, as shown in figs. 4 and 5.

An essential feature of these moulds is, that the cavitiesbefore mentioned are made open at one end, as shown in tig. 5. The object ot' this method ot'construction isto enable or 'facilitate the 4extraction of the bricks from the moulds after they are formed.

Upon the ends ofthe moulds, grooved piece-s, o o o o, &c., are rigidlyr attached, as shown in iigs.'.4 and 5. y

Immediately in the rear oi' said pieces, the strips o o o' o', &c., are fastened. These strips o' 0' o', 85e., are intended to enter the groovcsin the pieces o oo o, &c., as shown in iig. 4, and thus hold the series ot' moulds in firm and close connection with eachother.

The strips o o' o', 85o., should be of such relative width and thickness as to permit their easy insertion into, and withdrawal from the locking-pieces o o o 0,

When the series of moulds is connected as just described, the back part of each mould closes up the openings left at the ends of the biick-hrming recesses in the one immediately in front ot'it, so that the connection Aof' at least two sets of' moulds isreqnired to litthe recesses for the inouldinggoperation.. v

Upon the frame A, at a point indicated in fig. 1, the pug-mill or tempering-tub B is placed.

1t Aconsists mainly'of a lsquare vessel or receiver, that is provided with au upright shaft, a. s

Said shat't is furnished with radiating arms, set in a spiral manner, said alms being intended to work the clay, and properly prepare it for the manufacture of bricks.. y

The tendency of the arms operating is to force the vtempered clay do'wn through the opening i 2, lig. l, y into the cavities -in the mouldsm m m, Snc., as` they are brought successively beneathv said Opening; a

proper height intervening between the strips :c :t and the lower side of the tempering-tub, to allow of the easy passage ofthe moulds, when necessary.v v

'lhe shai't a is further providedwitlx an arm' or lever, c 1, to which the power is'. applied. that drives the machine.' y

As will be noticed, the upright.shaftal rests m a properly-shaped step or` foot-piece, which is fastened to the bottom ofthe temperingtub-B.- i

Near 'the top ot' .the tempering-tub A, to the side upon which the opening i 2'is nearest,a brace, lr, is attached by one of its ends. and is supported by a cross-piece, z, which is fastened by its endsto the upper-part of the frame A, as seen jat c 1, tgs. l and 3'.'

Upon the top ot' the tempering-tub B, another tim# ber brace is placed, as' seen at 3, lig 1.

This brace has a position immediately above, and in a line with the piece 1', and is supported at itsouter end, x 2, upon said piece Ivr, as seen in figc-.1.

v lhe adjacent sides of the pieces s and'r are par, allel to each other, a proper distance intervening between them.y

Upon each s ide of the frame A, at the frontend, the upright levers ll (l are attached, so as to secure them in position, and alsoallow a proper degree oi' oscillation upon the retaining-bolts or screws e e. (Sec ligs.1 and 3.) l

Thenpper ends of the levers d al are connected by the cross-piece l. (See iigs. l and 3.)

About the centre of the, piece l, the upper half w of the jointed lever w t is tastenedby a hinge, 5, ligs. v

1 and 2. Said lever is slotted, so as to surround the The otherenl rests upon,`

shaft a, and permit saidV shaft to work freely without coming in contact with said lever wt, as seenein tig. 2.

Upon the upright shaft a, at a point directly above the upperl edge ofthe tempering-tub B, aproper-sized `pulley or bandwheel, 8, is rmly fastened. The position given said wheel brings it immediately beneath the piece s.

Upon the piece fr, between it and the piece s, another hand-wheel, 10, is placed. It is intended to be made of the same width of face as the wheel 8, but of one-third its diameter.

Each o f these wheels has studs or pins inserted in its face at regular intervals, as .shown in gs. 'l and 2. Y

These pinsare intended to enter holes made in the driving-belt o 1, that is placed upon the two wheels,

`thus preventing any possibility of said belt slippingr while the machine is in operation.

The smaller wheel, 10, isretained in position by a shaft, that passes through both the pieces s and r and the centre of said wheel.-

The upper end of said shaft is provided with a crank, l2, figs. 1 and 2.

This crank has a pin at its outer end that connects to the end k-of the lower part tof the jointed lever w t; said lever having its two portions connected by al swivel-joint attachment at V. (See iig. 1.)

Upon the front side of bar l the two uprights u u are` attached at their upper ends by a bolt in each, thatthus secures them in position. (See iig. 3.)

These nprights are fastened at their lower ends to the piece fi. (See iig. 3.)

Said piece i has plungers or presser-feet attached to its lowerface. These correspond in number and position tlthecavities in the moulds, so that when a mould is brought properly beneath the piece fi, while the machine is operating, the presser-blocks will be immediately above the cavities. And as the jointed lever 'w t receives motion from the crank 12, it is -evident that the levers d l will be vibrated a proper distance back and forth, and thus cause the presserblocks ont/i to rise and fall, or be forced down upon the filled mould that is beneath them.

Upon each side of the machine, at a proper point,

rindicated in fig. 1, the rails c c are placed.

They are connected at the rear end by the crosspiece g2.l (See fig. 2.) They rest upon the upper ends of the legs ofthe frame A.

y At a point, 2, (see iig. 1,) upon each side of the machine, the levers ff l are fastened tothe rails c c.

f Said fastening lor attachment is so made as to permit a limited movement of the levers f f 1 up and down l in slots made in their ends, through which the retaining-boltsor screws pass. y

The other ends of levers f j' 1 are pivoted to the sides ofthe frame A, (see fig. 1,) at 1.

. The lower ends of upright levers d d are pivot-fast ened or jointed to the ends of the connecting-links g g 1; the other ends of said links being attached in like manner to the levers f f 1, at points about midway between their ends, as seen in tig. 1, at 3.

Upon the mils' c c, at a point shown in Iig. 1, the blocks n nare placed and fastened thereto, so as to slide freely back and forth with said ra'ils.

Said blocks are made of a ,proper height to receive upon their tops the -ends of the scraper b. Said scraper is intended to strike cti' the superfluous clay (during the process of moulding) from the top of the mould as it assumes its position in front of it.

AHaving given a full description of the construction of the device, its manner of operation is as follows:

The moulds m .m m, &c., are placed (one'ata time) upon the guide-strips or rails a: x, immediately in front of the cross-bar g l. Upon communicating motion to theY machine, before clay is placed in the tempering-tub B, the action of the levers d fl causesthe sliding rails c c to move forward a proper distance at each stroke ofthe crank 12. Upon each return-stroke another mould is placed in connection with the vpreceding one, by simply sliding the hooks o o, &c., down over the tl-anges o' of on the mould in front. This action connects the moulds iirmly together. By continuing the operation, the moulds are brought successively beneath the opening i 2 in the bottom of the tempering-tub B; and as the clay is-tcmpered in said tub, 'and forced down into the cavities in the moulds, the scraper or strike-cti` 'b clears the top face vof each mould as it advances from beneath the tempering-tub, after it has been filled therefrom. )Vlieu the. tirst-tilled mould is brought, by the action ot' the machine, beneath the presser-blocks on the -benm i, the down-stroke of said blocks will canse, them to press with a suicient degree of force upon the clay in said mould toperfectly consolidate the moulded n bricks; The next rise ofthe plnngers or pressers releases the mould, and the action of the machine car- `ries it forward so that it can be disconnected from the one in its rear, and taken out ofthe machine `and emptied. A sufficient number of moulds being provided, the operation of making the bricks can be continued at pleasure.

.The position assumed by the working-parts of; the machine, when the side-bars c c have been moved their full throw forward, is shown in iig. 1, by the red lines This operation, as has been shown, carries the train of moulds forward a proper distance. The return back of the bars c c, permits the coupling on of another empty mould, as will be seen upon inspection of iig. 1.

f As I design to apply for a patent for another improvement in brick-machines, in which `several of the characteristic features of the present application are made use of, for the purpose ot' distinction I designate this application a's Division 1.

Having given a full, clear, and exact description of my invention, and its manner of operation,

lWhat l claim as new of my invention, and desire to secure by Letters Patent ofthe United States, is-

'lhe combination andV arrangement, in thepecnliar Amanner herein shown, of the png-mill B, moulds m m m, and strike-off knife b, when said knife b is supported upon and operated by the rails c c, that communicate lnotion to the moulds in m m m, for the purpose herein described.
