GEORGE E. GOLDNER, OF FORT DODGE, IOWA.

BRICK-CARRIER.

To all lwhom it may concern.' i

Be it known that I, GEORGE E. GOLDNER, a citizen of the United States, residing at Fort Dodge, in the county of W'ebster and State of Iowa, have invented certain new and useful Improvements in Brick-Carriers, of which the following is a specification.

This invention relates to certain improvements in brick carriers, clamps or the like; and the objects and nature of my invention will be readily understoodv by those skilled in the art in the light of the following explanation of the accompanying drawing illustrating what I now believe to be the preferred embodiment from among other constructions and arrangements within the spirit and sco-pe of my invention.

The invention consists in certain novel features in construction and in combinations and arrangements as more fully and particularly set forth and specified hereinafter.

Referring to the accompanying drawings F igure l, shows fine superimposed bricks in section, showing the carrier, in longitudinal section, fitted in and adjusted to support said bricks. Fig. 2, shows the carrier in longitudinal section with the parts in normal or inoperative position. Fig. 3,

a detail elevation of one of the reciprocatory expanding rods. Fig. 4, is a cross section through one of the supporting members on an enlarged scale, the blades being shown projected.

The particular object of the invention is to provide a carrier, to perform generally the functions of what is known in the brick making art as a brick clamp, and embodying means to enter alined transverse holes extending through a series of parallel bricks. provided with a series of brick supporting elements designed to clamp, grasp, grip or otherwise support each brick at a point within said hole or holes therethrough, whereby a series of bricks can be carried without necessity of engaging the faces thereof. A carrier of this character is of peculiar advantage for use in carrying green bricks from the brick cutter to the drier or to the cars or other means to convey the bricks to the drier, particularly as green or soft `brick having ornamental or roughened facesor surfaces can be thereby handled or carried without danger of mai-ring or defacing such surfaces or faces by contact wit-h the hands of the operators or with portions of the common brick clamps, although of Specification of Letters Patent.

course my invention is not limited to carrying green brick.

The bricks a, for which the carrier of my invention is particularly designed, are formel with two transverse holes b, therethrough, usually located about midway between the center and ends of each brick and centrally between the longitudinal faces of the bricks. These holes are usually formed by the brick or die machine in the continuous soft clay bar projected from such machine. The brick cutter forms transverse cuts through this bar and t-hus divides the same into rows of parallel bricks and the otl' carrying belt car- Iries these bricks, or the bar thus severed, from the cutter. The particular example of my invention illustrated, in the drawings, is designed to extend through and carry not more than five standard size bricks.

The carrier as illustrated, comprises a pair of elongated parallel supporting members l, spaced apartaccording to the spacing of the holes Vand designed to enter said holes and extend through the series of bricks constituting a load, and these members forni part of a stiff or rigid supporting frame which usually comprises a transverse handle 2, connecting and rigid with the upper ends of said members, although of course, I do not wish to limit my invention to the emn ployment of two supporting members, as it might be found desirable to form the bricks, each with one or more alined holes. In the example illustrated, each member l, is longitudinally tubular and closed at its lower or free end by a rounded plug or cap 10, to facilitate insertion in the brick holes. Collars or stops 12, are usually arranged on the upper or handle-end portions of the sup porting members to approximately iit or engage the top flat face of the upper or outer most brick of the pile or series receiving the carrier, and to limit the inserting or apply ing movement of the carrier into or through the bricks.

Each supporting member is provided with a longitudinal series of brick engaging devices, one or more of such devices being provided for each brick, such devices being so spaced apart and arranged that each brick will be internally engaged thereby aboutmidway the thickness of the brick.

In the specific example illustrated, the brick engaging devices are normally withdrawn within the tubular member and from operative brick engaging position to permit insertion of the member through the bricks and to permit withdrawal of the member therefrom, and means are provided for projecting said devices to operative brick engaging position and whereby said devices can be withdrawn. Various arrangements and constructions can be provided to accomplish these results and perfo-rin such functions. For instance, I show the tubular members provided with several sets of radial slots or openings, in which are arranged normally withdrawn radially movable blades or flat fingers 3, of such length that when projected radially and outwardly through said slots and from said member they will extend into the soft material of the bricks the necessary distance to support and uphold one end portion thereof or even the entire brick. I show these blades 3, carried by the lower free ends of plate springs 30, arranged longitudinally within the tubular member and at their upper ends fixed at the inner surface thereof. These springs are arranged so that their free ends constantly tend to spring inwardly and thereby withdraw the blades with their outer ends within the circumference or outer surface of the tubular member.

Usually four radiating blades, arranged in a common transverse plane, 90 degrees apart constitute a set, although I do not wish to so limit my invention. The sets of blades carried by a tubular member are arranged a distance apart equal to the thickness of the brick, and are so arranged with respect to the exterior stop or collar 12, or other gaging means, that each set of blades will be located at about the vertical center of a brick when the tubular member is in operative position within the bricks to be lifted thereby.

Suitable mechanism is provided for pro jecting the blades. For instance, I show each tubular member provided with a longitudinal internal reciprocatory or sliding rod or bolt 4, arranged approximately throughout the length of the tubular member and centrally between the free ends of the springs 30. This rod carries a series of upwardly reducing tapered portions or cones 40, rigid therewith, one cone being provided for each set of blades and extending below the same. The normal position of the rod is at its limit of downward movement with each cone below its set of blades permitting the blades to assume withdrawn inoperative position. When the blades are to be pro` jected to operative position, the rod is moved upwardly or toward the handle end of the tubular member thereby causing the cones to engage the free ends of the springs 30, and force the blades outwardly to project into the clay of the bricks. When the tubular member is to be withdrawn from the bricks, the expanding element (rod and i cross bar 5, as by having their ends threaded and screwed into and through the cross bar ends. rIhis cross bar extends between the upper or handle ends of the tubular members and is arranged between the collars 12, and the carrier handle 2, and is usually spaced from and approximately parallel .with said handle 2. The cross bar 5, pro` vject-s through longitudinal slots in the tubular members and forms an operating means or handlel for the expanding members whereby they can be simultaneously and uniformly moved to blade projecting position. rIhe cross bar 5, rigidly connects the two rods of the expanding members to form a -rigid U-shape frame and causes said rods to move longitudinally together or in unison. Coiled expansion springs 6, are usually `provided to return the expanding elements in normal inoperative position. I show these springs arranged in the upper ends of the tubular member bearing on the ends of the cross bar 5, and at their upper ends yseated against rigid portions of the carrier handle so that the springs resist movement of the expanding elements and the cross bar 5, toward the carrier handle.

Means can be provided to detachably lock the expanding elementsin operative bladeprojecting position and against the tension of said springs. For instance, I show one end of the cross bar 5, within a tubular member formed with a shouldered or hooked projection 50, to project through slot or notch 51, formed in the wall of the tubular member inclosing said projection 50. When the cross bar 5, has been pressed toward the handle 2, to project the blades 3, the projection 50, is in line with notch 5l,V and slight lateral pressure will move the cross bar 5, endwise or longitudinally a sufficient distance to move projection 50, into said notch, so that when the cross bar is released its projection will engage and catch on the edge of the tubular member forming the lower wall of the notch, and thereby lock the parts in expanding position. The rods 4, are allowed sufficient lateral play or are sufficient-ly resilient to permit this lateral movement for locking When it is desired to release the cross bar, pull thereon toward handle 2, will release projection 50, from the notch and the rods 4, spring laterally to normal position and carry said projection from the notch and and unlocking permit springs 6, to return the expanding members to lowered position.

In operation, the tubular member can be readily inserted through a set, say of tive, green bricks, resting on the apron of the cutting apparatus. The cross bar 5, is then pressed toward the carrier handle to project the blades into all the bricks. The lexpanding elements are locked in Operative position by the locking device. The pile of live bricks can then be pulled from the apron onto the off-bearing belt and then carried by the handle to the point desired. rI`he cross bar 5, can be released so that the springs will return the expanding elements .to normal position permitting withdrawal of the blades. The carrier can then be withdrawn .from the bricks without injury thereto or defaeement thereof.

This device can also be employed for various purposes in handling green, dried, or even burnt bricks, where such bricks are formed with alined transverse holes.

It is evident that various changes, modifications and variations might be resorted to without departing from the spirit and scope of my invention, and hence I do not wish to limit myself to the exact disclosure hereof.
