MACHINE FOR HANDLING IBIBICK S.

Specification of Letters Yatent.

Patented Nov. 1, 1910.

Application filed October 8, 1908. Serial No. 456,698.

To all whom it may concern:

Be-it known that I, RAYMOND C. PEN- FIELD, a citizen of the United. States of America, residing at New York city, in the county of New York and State of New York, have inventedcertain new and useful Improvements'in Machines for. Handling Bricks, of which the following is a specification, reference being had therein to the accompanying drawing.

My present invention relates to a machine for handling bricks, said machine being of the class employing a method described and claimed in my co-pending application for Letters Patent, filed October 8,

1908, Serial Number 456,692, which method consists essentially in lifting a mass of material, such as brick, by power applied horizontally at the ends of the base of the mass of material, said base being shorter than the rest of the mass and consisting of a number of detached blocks laid close to each other without any openings between. 111' the same co-pending a plication, I have also described and c aimed a form of mechanism for carrying the method into effect, which mechanism comprises essentially a pair of clamping members designed to exert their pressure laterally against the ends of the shorter basic layer of bricks, and said clamping members being actuated by suitable loverage means carried by a vertically-disposed frame. Y

My present invention consists in novel and ingeniousmechanism for accomplishing the same object as that sought for in my copending application referred to, and performing the same method of o eration. It

differs, however, in mechanica details for effecting the clamping at the ends of the lower tier'of bricks.

The invention, therefore, consists essentially in the construction, combination and arrangement of parts, and in numerous details and peculiarities thereof, substantially -as will be hereinafter described and claimed.

In the accompanying drawings, illustrating myinvention, Figure 1 is an elevational view of my improved machine for handling one of the clamping plates.

Similar characters of reference designate correspondintg lparts throughout the different figures o t e drawings.

The main frame of the apparatus is of a general upright construction, in order that it may lie alongside of the stack formation of brick in proper position to permit the clamping members at the bottom end thereof to be projected at the ends of the shorter basic layer for the purpose of tightly clamping the latter, and soalso that the upper laterally-turned portion of the frame may project over the mass of brick. so as to be in a position to be suitably engaged by a lifting crane or other device at a''point where the mass can be supported without'interfering with its center of gravity. This main frame in the present example of the invention consists essentially of two inclined bars 1, 1 secured near their upper ends to central uprights 9, which-are turned at their upper ends, at 2, said laterally-turned upper ends being secured together by means of a bolt 3'. Between the laterally-turned ends 2 a'horizontal lever 4 is fulcrumed upon saidbolt 3, and tothis horizontal lever is pivoted an eye 5, to which a lifting crane may be attached. At the opposite end of the lever 4 from its pivot 3 a cross head 6 is pivotally hung by means of a bolt 7. To the opposite inclined links 8 which extend downwardly alongside of the inclined bars 1, 1 of the main frame. The frame also comprises the aforesaid pair of parallel uprights 9, 910- cated between the inclined .bars 1, said uprights being united to the bars 1, 1 near the top of the frame, and at the bottom bein secured to a block. 10 which is made integra with or is firmly attached to a base frame 11. To this base frame 11 the lower ends of the inclined bars larebolted as shown in Fig. 1. The base frame 11 is a horizontal rectangular structure illustrated full in Figs."2 and 3. Its form may vary wide y provided only that it is so shaped as to accommodate there'- in the mechanical elements at the base of and the devices for operating them.

The lower ends of the long links 'or arms 8, 8 are pivoted to long transverse levers12 which cross each other, and are placed substantially horizontal, and the opposite ends of which are rigidly attached to horizontal lower frame 11. These rock shafts, moreends of the cross head 6 are pivoted two long the machine, including the clamping plates rock shafts 13suitably journaled in the over, are rovided with rigid crank arms 14, each sha t having'preferably two of these arms, and said arms'are pivoted to the rear faces of the clamping plates 15. In order to enable this pivoting to be accomplished with facility and strength,'I preferably pro.- vide on the rear faces of said clamping plates pairs of ears a a as shown in Fig. 5, the

"crank arms- 14 bein'gpivoted between the members of these pairs of ears. The clamping plates 15 have vertical faces as shown'in Figs. 1 and 2, and preferably at the top and bottom they are built. with broad, flat flanges 16' which, if desired, may rest beneath the overhanging'edges of the upper mass of brick which projects over the ends of the shorter basic layer. I am not restricted, however, to making the clamping plates15 with these broad flanges 16, as they may be omitted if desired, though in that case the plates themselves might be made sufliciently thick to furnish broad upper edges. In a word, however, the detailed construction, shape, dimensionsand general plan of the clamping plates may vary within; wide llmits, it being only essential that they should be so=made as to be able topexert a very strong clamping effect against .the ends ofthe lower tier of brick. It is found desirable in the operation of clamping plates of, this kind,in order to keep the clamping faces vertical duringthe movement of the clamps, that I should use additional arms I similar to the arms 14 and. pivoted to the for pur oses of shipment and otherwise. It

is possi le, however, that the machine mi ht be utilized'with 'a mass .of loosely set brick arranged for drying or burning, provided, of course, the lower layer is set solid and ,WlthOllt any openings hetwpenthe members or units. The p.ai r o'f' clamps 15, when the -ma'cliii1 is about to be used, apply their gripping faces to the ends of the lower course of bucks and by tightly clampin the same enable the mass of superposed brie s to be lifted as the result of the horizontal st-rainimparted to the basic layer. At times, however, if desired, a vertical lifting strain may be exerted by: the upper edges or faces of the clamps beneath the overhanging parts of the upper mass simultaneously with the lateral clamping effect produced by binding the clamps horlzontally against the ends of the lower course' The employment of" long levers, as 12, at the base of the machine,

which are actuated by the long" links running to the top of the frame, enables a very strong clamping efiect tobe produced.

In the operation of the machine, some suitable lifting crane or other supporting means will be'caused to engage the eye 5 at the top of the frame, and this will oscillate the lever 4 upon its pivot and draw the two links" 8, 8 upwardly, which will rock the shafts 13 in their bearin s, thereby actuating the crank, arms 14 which are pivoted to the clamping plates 15, and forcing the clamping plates toward each other and against the ends of the short lower tier of brick. Atorsional strain is imparted to the shafts 13, 13, as the result of th'e action thereon of the long levels 12, and the power 1 with which the cranks 14 urge the clamps 15 against the briek is very great indeed. In other machines similar purpose, some of which I have invented and patented, and others of which certain of" my ented, theinitial lifting movement on the frame operates automatically to actuate clamping devices at the base and cause them toengage the brick after a certain fashion, entirely-different, however,

from my Present machine. But in those cases the lever at the top of the vertically- "disposed main frame has generally been arranged so that when the crane lifts the machine certain thrust bars will operate downwardly againstlevers at the base of the machine for the purpose of causing the clamps to dov their duty; but in my mechanism, in the present instance, I have departed widely contemporaries have pat-.

having alike function and from that function by substituting therefor an action which is such that when the crane lifts the lever at the top of the frame, the

links connected to said lever through the cross head, as. described, will lift the long levers at the base, so that the operation does not involve a thrusting action Y downwardly, but a ulling action'upwardly. As the result of scribe is successfully practiced, and I am enabled to grip with perfect case a lower course of brick in such a way as to lift and transport the entire mass. Having thus described my invention, what I claim as new and desire toseeureby Letters Patent, is:

1.
