' 'Applicationjfled April 7, 1911. Serial No. 619,552. f

To all whom it may concern: ki

kBe it known that I, 'WILLIAM H. ANDER, a citizen of the ,United States,-and a resident of Long Branch, in thel county of Monmouth and State of New Jersey, 'have invented a new and Improved Concrete- Mold, of which the following is a full, clear, and exact description.

My invention relates to concrete molds and it has for its object to provide one hav-k ing a bottom member which may be conV` veniently rotated and lowered so that a detachable end member will rest on the ground, the mold being provided with side members which have clamps for engaging the detachableend member, and means by which the side members are' moved laterally relatively to the bottom member.Y f

Additional objects of the invent-ion will appear in the following'complete `specification, in which the preferred form of the invention is disclosed.

In the drawings similar,y characters of ref* erence indicate corresponding parts in all the views, in which Figure 1 is a side elevation of` theinvention.; Fig. 2 is a fragmentary sectional view on the line 2-2 of Fig. A1, with the body member disposed in a yvertical position; Fig. 3 is a front elevation of Fig. 2; Fig.4` is an end view showing kthe body membery in an inverted position; Fig. 5 isa sectional eleva` tion showing the body member in a vertical position; Fig. 6 is a fragmentary sectional View showing the means by which the clamping members are connected with the rods, by which they are operated; and Fig. 7 is a perspective view showing one ofthe bearing members.

` By referringk to the drawings it will be seen that a frame is provided, consisting of the side members 5, which are connected by a transverse member 6, which is right angular in cross section, this transverse member 6 being riveted to the side members 5 at 7. Supporting wheels 8 are journaled inthe `sides 5 of the frame. The top of the side members 5 have bearing surfaces 9, on which the bearings 10 of the bearing members 11 are adapted to rest, these bearing members 11 having guide ,members 12, which are' disposed in the guideways 13, secured to the side members 5. At the lower terminals of the guide members 12v there are depending ears 14, which are adapted to be engaged-.by

ALEX- the cams 15, which side members 5. w n Secured to a rock shaft 17, which is jour-` naled in bearings 18 in t-he side members 5, there are cams 19, these cams 19 being adapted to engage thecams 15 for moving them, and raising the guide members 12.y Stops 20 are secured to the side members 5 for limitingk the movement., of the kcams 19.` There is secured to the shaft 17, at'the outer Specification of Letters Patent. Y Patented Dec. 17, 179127.y i

are pivoted'atll to the l l l side of one of the side members 5, a lever '21,' by which the rockshaft 17 maybe conveniently-moved, as maybe desired.

Journaledv in the bearings 10 there isa body member 22 rhaving flanges 23, ywhich are engaged by the flanges 24Qon the end member 25y which forms part of the bodyYK member, the flanges 23 andl24 being secured v f together by bolts 26. A study 27 is disposed in an opening v28 in the body member 22,

this stud 27 being` held inplace .by a' vset* screw 29. Mounted to rotate on. the studf27 there isa wheel 30 having cam grooves 31".' Fulcrumed at 32 to the bottom `of the body member 22 there are levers 33, one'jset of terminals 34 of the said levers 33' being dis.- posed in the cam grooves 31, the other set of terminals 35 of the levers 33 being articuf lated to laterally disposed tie members v36,

these tie members 36 having upwardly disposed terminals 37.

Two side members 38 are provided, these side members resting normally on the body member 22, the body member 22 .having lateral `projections 39, which are adapted to support the sidemembers 38 when theyl are moved outwardly. Straps 40 are secured to the outer sides of the side lmembers'38,and in these straps 40 A there are disposed tiedmembers 41, the tie members 41 having straps 42 in which are disposed the terminals 37 of the tie vmembers 36.y

Blocks 43 are secured to the sides of the side members 38, so that when the tie mem* 'bers 36 are drawninwardly, they will carry i with them the side members without anyv lost motion. The clamping kmembers `41 have flanges 44, vwhich are normally disposed in recesses 45, in the removable endmember 46 of the mold. Springs v47 are provided one for each of the 4clamping members 41, the

springs connecting the clamping members with one set of straps 40, so that the clamp#y ing members 41 will be held yieldingly in a" f predetermined position relativelyto theside members 38, the end member 25 of the mold having lateral projections 48, each with a slot 49, the clamping members 41 being disposed in these slots 49. The head members 50 are provided with threaded orifices in which the terminals 51 of the clamping members 41 are disposed, nuts 52 being provided for engaging the threaded terminals 51 to lock the head members 50 in position.

Articulated to the head members 50 one at each side, there are links 53, these links 53 being connected by a transverse member 54 to abut against the terminals 51 of the clamping members for moving the said terminals inwardly. rlhe link members 53 have terminals 55, which rest against the rear of the lateral projections 48 of the end member 25. To the terminals 55 of the links 58 there are articulated brackets 56, the brackets 56 at each side of the machine being riveted to rods 57, the rods 57 being articulated to wrist pins 58, secured to the wheel 30. rThe wheel 30 is provided with a crank 59, by which it may be conveniently turned.

Projecting` from one of the bearings 10 there is a journal 6G, to which a head member 61 is articulated on an axis which is vertical when the body member is in horizontal or normal position. Secured to this head member 61 thereV is an arm 62, with a hook 63, the hook 6B being adapted to engage and rest in the recess 64, in the bracket 65, which is integral with one of the side members 5. A lever 66 is secured to the head member 61, the aXis of the lever being at right angles to the axis otl the pivot 67, which connects the head member 61 with the journal 60. A transverse member 6 is provided with a threaded head 68, in which meshes a screw 69, the screw 69 being provided to engage the body member 22 at 70, and serve as a stop for the body member.

In using the invention the side members 38 and the removable end member 46 are disposed in position with the flanges 44 engaging the recesses 45 in the removable end member, and withthe clamping members 41 drawnv rearwardly and toward the center line of the machine to lock the side and removable end members, the mold formed by the body member the side members and the end members, is filled with concrete. rI`he device is then moved into a position where the operator desires to remove the concrete which is disposed in the mold. The operator moves the lever 66 toward the center line of the machine, which disengages the hook 63 from the recess 64, in the bracket, and he then raises the lever 66 to rotate the mold to the position shown in F ig. 5 of the drawings. The lever 21 is then raised slowly, the movement o f the cams 19 permitting the cams 15 to move downwardly and with them the bearing members 12. In this way the mold is moved toward the ground until the removable end member 46 rests on the ground. The operator then rotates the wheel 30 by means of the crank 59, so that the rods 57 are moved outwardly, and the arms 34 of the levers 38 are moved inwardly. This movement of the wheel 30 will move the links 53 into the position shown in Fig. 2 of the drawings which will draw the clamping members 41 outwardly, and with them the rear of the side members 38, andalso free their flanges 44 from the recesses 45. At the same time the movement of thellevers 83 will move the tie members 36 outwardly. As the clamping members 41 and the tie members 36 are moved outwardly they will carry with them the side members 38, and will permit the operator to raise the mold by a downward movement of the lever 21, the concrete being deposited on the removable end member 46, and being disengaged from the body member 22 of the mold, when it is raised. As the sidevmembers 38 have been moved away from the concrete by the rotation of the wheel 30, only one surface of the mold is in contact with the concrete when the body member is raised. However, if desired, the device may be moved rearwardly from the concrete so that the concrete will no longer be in contact with any member of the mold, when the body member is raised by the downward movement of the member 21. After the body member has been raised as has been described the lever 66 is operated to bring the body member to a horizontal position, as it is moved outwardly, so that the hooks 63 will be again disposed in the bracket 65. Another end member 46 is then provided, and is disposed in position, when by a rotary movement of the crank 59 the ianges 46 on the clamping members 41 will be locked in the recesses 45, in the new end member 46, and, at the same time, the side members 38 will be drawn inwardly, and will be locked with the end member 86, to permit of the re-illi'ng of the mold. It will be understood that when the clamping members 41 are moved to lock their tlanges 44 in the recesses 45 in the new end member 46, the springs 47 will draw the side members 38 into place.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:
