BLOCK ATTACHMENT FOR HYDRAULIC LIFTS Filed Aug. 11, 1939 A Home Patented Sept. 24, 1940 UNITED STATES PATENT OFFICE BLOCK ATTACHMENT Foe [HYDRAULIC LIFTS Charles Henry Pierce, Gilroy, Calif.
Application August 11, 1939, Serial No. 289,655
' 1 Claim.
vide a pair of blocks having means for attaching v them to the top of the lift very quickly and easily and such means permitting the blocks to be placed inwardly or outwardly with respect to the beams at the ends of the head of the lift.
This invention also consists in certain other features of construction and in the combination and arrangement of the several parts to be hereinafter fully described, illustrated in the accompanying drawing and specifically pointed out in the appended claim.
In describing the invention in detail, reference will be had to the accompanying drawing wherein,
like characters denote like or corresponding parts throughout the several views, and in which:
' Figure 1 is a view of the upper end of a hydraulic lift showing the two blocks in use on the beams of said lift. I
Figure 2 is a top plan view of Figure 1.
Figure 3 is a perspective view of one of the blocks.
Figure 4 is a fragmentary view showing how a block can be placed at the inner edge of a beam instead of the outer edge as in the other views.
As shown in these views a pair of blocks B is used and each block is of substantially rectangular shape and elongated with its upper corners cut off on a bevel as shown at I. An L-shaped strap Z'is fastened at the center of one face of the block by the bolts 3, said strap extending be- Q yond thelower, edge of the block where the short arm 2 of the strap extends under the block to form a space between itself and said bottom of the block. A pair of straps '4 are placed in grooves in the underface of the block adjacent the ends thereof and these straps 4 project a considerable distance from that side face of the block which is opposite the side face ,to which the strap 2 is connected and the outer ends of these straps 4 extend downwardly at right angles as shown As is well known the movable member 5 of a hydraulic lift used for lifting automobiles and'the like has a head 6 at its upper end adjacent opposite ends of which are located T-beams l and these blocks of my invention are placed on these beams. As shown the block is slid along the top of a beam with a portion of the top of the beam (Cl. 254-89) I engaging the space between the arm 2' of the strap 2 and the bottom of the block and the other edge of the'top of the beam being engaged by the dependingportions 4' of the straps-4.
' The blocks can be placed on the outer portions 5 of the beams as shown in Figures 1 and 2 or upon the inner portions as shown in Figure 4, depending on the type of motor vehicle being lifted by the hydraulic jack. The dotted lines in Figure 1 show portions of 0 the frame of a vehicle being lifted by the jack and as will be seen the blocks engage these parts of the frame of the vehicle.
It willbe seen that the metal straps 2 and 4 act to hold the blocks firmly on the beams of the'jack withoutdanger of the blocks falling off and the blocks can be easily and quickly placed on a beam'or removed therefrom.
Each blockv has an eye-bolt 8 connected to one end thereof for facilitating handling of the blocks. I y
It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent. I
It is to be understood that changes may be made inthe construction and in the combination and arrangement of the several parts provided that such changes fall within the scope of the appended claim.
Having described the claimed as new is:
Means for increasing the height of certain portions of the flanged beams of a hydraulic jack comprising'blocks for resting on the beams, each invention, what is block being of substantially rectangular shape and of less width than the width of the beams and having laterally extending grooves in its bottom face,'metal bars fastened in the grooves and extending beyond one side face of the block with their outer ends turned downwardly at right 7 40 I angles for engaging a side edge of a flange of a beam and another fiat metal bar attached to the second side face of the block and vertically arranged with its lower end projecting beyond the bottom face of the block with the extremity of said lower end bent at right angles and extending under the bottom face and spaced therefrom sub- 'stantially the thickness of a flange of the beam, the extended and bent lower end of the last-mentioned bar and the bent ends of the other. bars with thebottom of the block forming guideways for the flange of a beam.
