rMPRovEMENTiN celex-MACHINES.

The schedina referred to in time Leners Parent ana making pare of the mme.

To all whom it may concern:

Be it known that I, JOHN R'. WILLIAMS, of Taunton, in the county of Bristol and. State of Massachusetts, have invented a new and improved Brick-Press; and I do hereby declare that the following is a full, clear, andfexact description thereof, which will enable others 'skilled in the art to make and use the same,V reference being had to the accompanying drawing forming part of this specification, in which- Figure l represents a plan or top view of my improved machine for pressing brick.

Figure 2 is a side elevation of the same.

' Figure 3 is a vertical longitudinalsection of the same, taken on the plane of the linea: fr, fig. 1.

Figure 4 isa vertical transverse section of the same, taken on the plane of the line y y, fig. 1.

Figure 5 is a detail vertical section on an enlarged scale of the press and plunger.

Similar letters of reference indicate corresponding parts.

My invention relates to brick-presses, and consists in certain features of improvement, which will first be described in connection with all that is necessary to a full understanding thereof', and then clearly specified in the summary or claim.

Ain the drawing represents the flame of my improved pressing-machine. The frame is made of wood or other suitable material, and of such size and shape as to be best adapted for the support of the machinery connected with my press.

The sides ofthe frame are. straight or nearly so, to benear to the straight edges of the endless belts B and C that are fitted over drums near the' two sides.

1n the frame A are'the bearings of two horizontal transverse shafts, I) E, one being near cach end of the frame.

The ends of these shafts carry drums a a, which serve to hold the broad belts B C, as shown.

The shaft E carries one or more ratchet-wheels, b, so that it will receive intermittent rotary motion from a pawl or pawls, e, pivoted to swinging levers d.

In the middle of the frame A is hung the horizontal transverse driving-shaft F, which receives rotary motion from suitable machinery to transmit the same tothe pressing and feeding apparatus.

Whenever the cam It strikes and depresses the levers H it will thereby extend the toggle-levers and move the sideI pieces together.

apart by the springs h.

I is the vertically-adjustable plunger of the press.

Its shank lis toothed and meshessinto the teeth of a pinion, nawhich receives rotary motion from a toothed wheel, n.

I The wheel n is mounted upon a shaft, o, which carries also a pinion, p, shown in lig. 1,-and bydotted` lines in figs. 2 and 3.

The pinion p receives rotary motion from a toothed wheel, r, on a shaft, J.

rlhe shaft J serves as a pivot of a swinging frame,

L, which frame embraces the sides of the fram'eA,v

of the driving-shaft F,.will release the plate M and y frame L from the'catch.

Another cam, V, on the shaft F, serves to swing the frame L,on its pivot J, into the both aforesaid positions.

rlhe cams vzt and c may he double on the shaft F, that is to say, one on each side of the frame A, asindicated in iig. 4.

The plate M, when it swings away from the press, strikes the lever or levers d, and imparts thereby intermittent rotary motion to the shafts D E and, belts B C The swinging motion of the frame L serves, by the gear-wheels nan, 1r, and r, to impart vertical reciprocation to the plunger I, in suoli manner that the said plunger is moved down whenever the plate M is carried over the press, and upA when said plate is carried away from the press.

The plunger proper is made of two plates, w and o5, between which an oil-chamber, y, is formed.

Between the ,plates w x is` clamped a sheet, s, of paper or othcrfabrie, that projects slightly beyond the edges of the plunger, as indicated in iig. 5. The fabric will be soaked with the oil from the chambery, and will, during the vertical adjustment of the plunger, wipe and smoothen thc sides and ends of the press. rlhis lubricating quality of the' plunger is of great importance, not only for facilitating the movements of the' same, but also for preventing the clay from adhering to the sides of the press.

As soon as the cam le leaves the levers H the sides e will again be moved' This By means of a belt, a', or otherwise, the shaft F imparts rotary motion to a vertical arbor, b', hung in the frame A.

'lhe arbor b carries a. toothed segment, e', which, meshing into a pinion, d', serves to partly move the same.

The pinion d' is mounted upon thc lower part of a vertical shaft, N. The upper part of this vshaft carries a toothed wheel, c', which meshes into the teeth of a sliding rack, f.

The rack j" is arranged to slide in a horizontal grooved frame, 0, which is supported transversely above the trame A aml press, extending over the belt B, as shown.

The rack f carries a vertically-mijustable frame, I, which is provided with or suspended from slotted arms g', and by which it is made vertically adjustable.

A spring, h', acting on the shaft N, serves to turn the saine so that the wheel e will throw the rack f and frame l over the bclt'B, asin iig. .1.

turns the shaft N so as to carry the frame 1 toward the belt (l, into the position indicated by dotted lines in tig. l. In this latter posit-ion the shaft N and frame l will be automatically locked by means of a pin, i', which projects from the shaft N, and catches behind a spring catch,j', on the fra-me (l.

The plate M, when swung forward over the press, strikes the catch i', and releases the pin i', so that the spring 7i. may carry the shaft X around to move theframe l back over the bell l5.

\Vhenever the plate M swings forward over the press it swings up two bars or levers, R,whieh are pivoted to the sides of the frame A. lhesc bars or levers ll, when swung up, elevate the-flame P, preparatory to the release. of the pin i from the spring catch j". j The frame l has two proiecting' ears or ribs, l and an', of which one serves to feed the brick to the press, while the other moves them away to the belt C.

The operation of the machine is as follows: The brick to be pressed are placed in a single row upon a board, S, that is placed upon the apron B. A similar board, '.l, is placed upon the apron C. The rib Z' of the lia-me l will, when the shaft N is turned by the segment c', carry the 'first brick from the boa-rd S upon the plunger of the press, which is then tlush with J(he top of thesides and ends. \Vhen the brick has been fairly carried'upon the plunger the frame L swligs forward to carry the plate M over the press an. to elevate, ny means of't-he bars R, the frame l. At the same time the plunger is moveddown sufficiently to admit, the brick within the press, and the sides of the latter are contracted to fairly compress the brick. When the brick has been pressed the liu-une- L swings open again, the frame l is, by the spring h', moved over the board R, and the plunger to remove the `one previously made from the plunger to the board T.

The rspring catch j serves to lock the frame P after the salme has broughta new brick to the' press, and prevents thereby the rib m from throwing such brick back again.

When the board S has thus been emptied the board T will be full, and both are removed to make room for others,vwith which the operation can again be started.

By this means very rapid and entirely reliable op- 1- -Gl'ltoucan be obtained. The segment c', when it meshes into the pinion I,'

.Having thus described my invention,

I claim as new and desire to secure by Letters Patent-.
