RECEIVING-TABLE FOR BRICK OR TILE CUTTING MACHINES.

SPECIFICATION formingpart of Letters Patent No. 718,078, dated January 13, 1903.

Application filed July 21, 1902.

T0 at whom it may concern.-

Be it known that LJAOOB BENs1NG,a citizen of the United States, residing at Malinta, in the county of Henry and State of Ohio, have invented certain new and useful Improvements in Receiving-Tables for Brick or Tile Cutting Machines; and I do hereby 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 beinghad to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

Myinvention relates to improvements in receiving-tables adapted to be used in connection with machines employed in automatically cutting tile, brick, or other products from .one or more columns of clay or other plastic material as the same is continuously forced from the die of a mill, and especially designed tobe used in connection with the machines described in UnitedStates Letters Patent Nos. 411,638, 524,302, and 563,252, granted to me, respectively, September 24, 1889, August 14, 1894, and July 7, 1896, and it more particularly relates to improvements in the delivery device described in United States Letters Patent No. 621,315, granted to me March 21, 1899.

The object of my improvements is to provide suitable and effective means for carrying the tile or brick away from the cuttingmachine as they are received therefrom and place them in separated position on pallets arranged in position to receive them and carry the same, with the brick thereon, forward to a point where they are removed to drier-cars or otherwise disposed of, all of which is hereinafter more specifically described and finally claimed.

While the essential features of my invention are necessarily susceptible of modifica illustrated in the accompanying drawings, in which Figure 1 is a vertical longitudinal sectional view of myimproved delivery-table and pal let-carrier on the dotted line as a: in Fig. 2. Fig. 2 is a top plan view of the same. Fig. 3 is a vertical sectional view of my improved compensating gear. Fig. 4 is a transverse Serial No. 116,425. (No model.)

sectional view of the same. Fig. dis a plan view of the links forming the endless palletcarrier chain, and Fig. 6 is an end elevation of the same.

Similar letters and numerals of reference indicate similar parts in all the figures of the drawings.

In carrying out my invention I employ a delivery-table A, elevated in position at the forward end of the cutting-machine B to receive brick or tile therefrom, and the palletcarrier 0, arranged in subjacent position to said delivery-table A and having at its forward end a supporting-rack or delivery-frame D. Proceeding to describe in detail these several parts and their adjuncts, 1 designates the usual longitudinal sills upon which the machines mentioned are mounted. Rising from the sills 1 are the vertical legs or standards 2 of the pallet-carrier 0, said standards so pporting the sides 3, which are suitably connected and strengthened by the transverse bars 4. The sides 3 are provided with the endless inner track 5 and the outer track 6, running parallel with the upper and lower edges of thesides 3 and having conical bearing-surfaces between which is mounted an endless pallet-carrier chain having a series of pivoted orloosely-connected sections. These pivotal sections comprise a pair of base-plates 7, provided with thesingle and double perforated bearing-lugs 8 and 9 to receive the spindles or pins 10, on which are mounted the antifriction-rollers 11. The rollers 11 have conically-formed bearing-surfaces or peripheries to adapt them to fit the conical tracks 5 and 6 of the sides 3. It will be readily seen that by providing conical bearing-surfaces on the tracks and rollers the carrier always seeks or tends to move toward the center of the table, the wear of the tracks being thus compensated for and the carrier caused. to operate smoothly and with little friction.

Each pair of base-plates 7 is connected and held in rigid transverse relationto each other by a supporting-bar 12, being bolted thereto,

hereinafter mentioned, mesh and furnish the required motive power for the palletacarrier. The sections as thus constructed are connected in series to constitute the pallet-carrier by means of the pivotal bolts or spindles 10, which pass through the pairs of lugs 9 at one side of the base-plate and through the corresponding single lug 8 at the adjacent side of the next succeeding link or member and suitably secured therein. The carrier with the antifriction-rollers 11, which are mounted on the spindles 10, in position on the tracks 5 and 6, are shown in Fig. l.

Journaled in the rearward portion of the sides 3 is the transverse shaft 14, on which are mounted the large spur-gear 15, which is connected by a chain to gearing, hereinafter more specifically referred to, and the smaller spur-gears 16, which are located between the sides 3 and the upper and lower portions of the inner track 5 and in alinement'with the endless racks formed by the perforations 13 in the base-plates 7 and bars 12 of the carrierlinks, with which the spurs of the wheels 16 mesh, thus making provision for power to run the endless carrier-chain.

To the rear of the tracks 5 and 6 and on the upper edges of the sides3 is journaled the supporting roller 0r rung 17, which is for the purpose of forming a support for the rear of the pallets 18 as they are placed on the carrier-chain preparatory to being carried forward to a position to receive the brick or other deposits from the delivery-table A. Secured to the rear portion of one of the sides 3 are the vertical spindles 19 to receive the axially-perforated horizontally-disposed guidewheels 20, which are slightly elevated above the horizontal plane of the endless pallet-carrier and adapted to act as guides and limit the transverse movement of the pallets 18 as they are placed on the carrier.

The superimposed delivery-table A is for the purpose of receiving the brick from the cutting-machine B and carrying them for- I ward on a descending plane to a point where they are deposited on the pallets 18 as the same move forward, and comprises the sides 21, the thin sheet-metal plates 22 and 23, and the rungs or rollers 24 and 27, on which is mounted the endless belt or apron 25. The sides 21 have suitable lugs or seats formed on {their inner surfaces, to which are securely bolted the plates 22 and 23 at the front and rear portions thereof, respectively. The sides 21 also have the enlarged and circularlyformed'forward ends 21 to adapt them to rest on the upper surfaces of the sides 3 0f the pallet-carrier table 0 and to support the forward end thereof a suitable distance above the pallet-carrier chain to escape the pallets 18 as they are moved forward on the carrier in position to receive the brick or tile as they leave the forward plate 22.

The plates 22 and 23 have their upper surfaces corrugated or provided with longitudinal depressions, as shown in Fig. 2, for the visors on the same from adhering and sticking thereto, as is the tendency when a smooth surface is used and which has heretofore much retarded the descending movement of the brick or tile. The rear edges of the plates 22 and 23 are concaved or depressed, so as to form laterally-disposed pockets or troughs 26, the ends of which are closed to adapt them to retain a lubricating fluid therein. The front edges of the plates 22 and 23 are preferably beveled on their under sides and are adapted to be so arranged in relation to each other as to have their beveled edges overlap the pockets 26 in such manner as to form a narrow slit or feed-passage between the forward and rearward edges of the adjacent plates, as shown in Figs. 1 and 2, to permit of an overflow of fluid passing from the pockets and over the surface of the plates. Any

suitable means may be provided for supplying lubricating fluid to these pockets.

Journaled to the sides 21 of the deliverytable are the rungs or rollers 24 and the enlarged roller 27, all of which have their upper surfaces on a descending plane with those of the plates 22 and 23 and are adapted to carry and support the endless belt or apron 25. The shaft 28, which carries the roller 27, projects beyond one of the sides 21 and carries on its outer end the pulley 29. A belt 30 connects the pulley 29 with a pulley provided on the cutting-machine B, by means of which power is supplied to run the belt or apron 25. A roller 31 is journaled to the lower portion of the brackets 32 and is arranged in suspended position beneath one of the rollers 24 in close proximity to the large roller 27 and acts as an idler over which the under portion of the belt 25 passes. The tension of the belt 25 is regulated by means of the hand-screws 33, which extend through the upper transverse portions of the brackets 32 and bear against suitable lugs provided on the sides 21, thus adapting the idler 31 to be vertically adjusted and loosen or tighten the belt 25, as desired.

Rising from the sides 3 of the pallet-carrier table and adapted to act as supports for the superimposed delivery-table A are the standards 34. A brace 35 is provided on the forward standard 34, and, as will be noticed, its under surface is provided with the downwardly-extending web 36, which acts both as a strengthener for the brace 35 and as a feedregulator for the pallets 18 as they move forward on the endless pallet-carrier chain. I so arrange the brace 35, having the downwardly-projecting web 36 thereon, with relation to the horizontal surface of the palletcarrier as to provide only sufficient space to permit of one of the pallets 18 passing between the same at one time. Should it happen that more than one pallet is fed into the machine at one time or the end of one overlaps the next preceding pallet, the forward end of the upper pallet will strike against the web 36 and be held until the preceding or under pallet has passed beyond the same and will then fall in place behind the moving pallet and be carried forward in its turn to receive the brick as they drop from the forward end of the delivery-table A.

In the rear of each of the sides 3 of the pallet-carrier table is provided the vertical elongated slots 37 to receive the bolts 38, passed through the lower perforated portion of the adjusting-standard 39, which extends upwardly therefrom and is pivotally connected to the rear of the sides 21 ofthe delivery table. The 'lower portions of 'the standards 39 are also provided with the transverse segmental slots 40, adapted to receive bolts 41, which are also passed through the vertical slots 37. The standards 39 are provided on one side with an outwardly-projecting apertured lug 42, the said aperture being internally screw-threaded to receive the adjusting or stop bolt 43, which bears against the upper surfaces of thesides 3 of the pallet-carrier. It will be obvious that by loosening the nuts on the bolts 38 and 41 the delivery-table may be longitudinally or vertically adjusted and enable the rear plate 23 to be brought in close proximity to the endless chain of the cutting-machine in suitable position to receive the brick or tile therefrom.

I will now briefly describe the pallet-delivery frame D, which is pivotally secured to the upper forward portion of the sides 3 of the pallet-carrier table 0. The construction of this frame is similar to that described in my Patent No. 621,315, above referred to, and which is fully described therein. The object of employing this table is to provide suitable means for receiving the loaded pallets as they are passed from the endless pallet-carrier chain and to facilitate their being taken away by hand to drier-cars or otherwise suitably disposed of. This frame consists of the sides 44, pivotally secured to the forward ends of the sides 3 of the pallet-carrier, and has suitable rungs or rollers mounted in a frame pivotally secured between said sides 44 and adjustable therein, overwhich the pallets move.

To impart motion to the transverse shaft 14 ofthe palletcarriertableGand propel the end less carrier-chain, I employ suitable clutch mechanism. The motion is preferably transmitted through a line shaft 45, which is mounted longitudinally in suitable bearings 46, supported on transverse braces connecting the sills 1. The line-shaft 45 is provided with a beveled gear 47, which meshes with and drives a companion beveled gear 48, mounted on a transverse counter-shaft 49, located in suitable bearings 50, on whose projecting end is provided a frictional clutch or compensating mechanism, which is adapted to regulate the relative movement of the cutting-machine and pallet-carrier.

Any suitable construction of frictional gearin g may be employed, and although I will proceed to describe one simple and effective form of friction-clutch, yetI wish it to be understood that I do not limit my invention to any particular form of clutch or to, its location, as I may vary the same at will.

Referring to Fig. 3, it will be seen that the outer end of the shaft 49 is threaded, asindicated at 51. Over the outer end of the shaft 49 I slip the beveled gear 52, which is secured to the shaft by means of the binding-screw 53. 1 next slip upon the shaft the spur-gear 54, adapted to be loosely mounted thereon. Alternating with the spokes 55 and projecting through perforations in the rims and rest ing in suitable sockets provided in the hub of the spur-gear 54 are the pins or spindles 56, on which are loosely mounted the idler beveled gear-wheels 57, which are adapted to mesh with the beveled gear 52 and with the beveled gear 58, which. I next slip loosely on the shaft 49 and retain in place thereon by means of a collar 59, suitably secured to the shaft. The hub of the beveled gear 58, which is axially bored to receive the shaft 49, is enlarged and provided on its outer face with the annular V-shaped groove to receive the annular comically-flanged portion 61 of the binding-collar 62. Theinner surface of the collar 62 is provided with the elongated groove 63 for the reception of the feather 64, which is embedded in the shaft 49 and enablesit to havea longitudinal movement thereon and prevents any rotary move ment. It now remains, therefore, to provide a convenient and simple means forcausing and maintaining a proper frictional engagement between the parts described. I therefore slip upon the shaft 49 thecoiled expansion-spring 65, or, if preferable, a rubber collar, and beyond this a hand-wheel 66 is threaded on the end of the shaft. It will be obvious that by rotating the wheel 66 in one direction the collar 62 will have its annular conical flange 61 forced into frictional contact with the surface of the V-shaped groove 60 in the hub of the beveled gear 58, which is mounted loosely on the shaft andmoves-in the opposite direction to that of the frictioncollar 62 by reason of the fact that the idlers 57 the compensating gear 54.

The endless pallet-carrier chain is gearedto move slightly faster than the endless carrierchain of the cutting-machine and the endless apron 25 of the delivery-table A in order that the movement of the pallets may be slightly faster than the movement of the bricks on" the delivery-table and therefore receive the brick or other out matter in separated position thereon, as shown in Fig. 1, ready to be removed to drier-cars or other suitable place Without first having to separate them by hand. It is therefore obvious that much time and labor are saved by not having to separate the brick by hand as they are received from the cutting-machine and place them on the pallets preparatory to going to the drier and that the mutilating thereof necessarily incident to their being handled is entirely obviated.

It will of course be understood that I have merely shown and described preferred forms of construction of clutch mechanism, deliverytable, pallet-carrier table, and deliveryframe and that such mechanism and devices may be varied in their construction without departing from the spirit of my invention or sacrificing any of the numerous advantages apparent to those skilled in the use of this class of machinery.
