PRESS TABLE Filed Oct. l5, 1926 Patented May 13, 1930 l UNITED 1S PATENT cries ROBERT E. MANLEY, OF YORK, PENNSYLVANIA, ASS'IGNOR TO MANLEY MANUFAC- TURING COMPANY, OF YORK, PENNSYLVANIA, A CORPORATION OF DELAWARE PRESS TABLEV Application filed October 15, 1926. ySerial llo. 141,848.A

lThis invention relates to presses and has for its principal object the provision ofY a press having a table which can 'be elevated with minimum of ditl'iculty and expense into a plosition where it can be bolted to the standart s.

A further object of the invention is the provision of means to eliminate the heavy and also awkward counter-balancing system necessary to raise the tables of the heavier type presses.

In garage equipment presses it is essential to have the press sufciently sturdy to take care of any work that may be brought to it, at the same time providing as clear a field for the work as is possible and it is also essential that the table be so arranged that it can be elevated by one man.

The device forming the subject matter of this application provides a very simple table so constructed that a mechanic can wind both drums at the same time, elevating the table and can hold the table suspended in approximately the desired position by means of a pawl and ratchet and can then by-a slight movement of the suspending chains raise the separate ends to exact alinement for bolting.

In the drawings Figure 1 is a front elevation.

Figure' 2 is an edge elevation.

Figure 3 is a horizontal section taken just below the top iianges of the table.

Figure 4 is a rear view of the table.

The base of the press is composed of a pair of angle irons preferably bolted to the skids 11 and also directly connected to the channel members 15. At the side of each channel 15 and secured thereto in a plurality of points are two bars 17 each perforated at regular intervals as at 18 and bolted to small angle pieces 20 which are also connected to the base angle pieces 10. Preferably the bolt 21 connecting the bars 17 to the angle pieces 20 also connect the horizontal straps 22 which space apart the two standards and prevent their spreading at the bottom, these straps being tension members principally.

-At the top the four bars 17 are connected together by the usual cross piece 25 which carries cent-rally a press 26 and at one side a small rack press 27.v Somewhat below the cross piece 25 the two bars 17 of each pair are connected together by a pipe spacer 30 of theusualtype, that is, a piece of piping between the bars and a bolt passing thru the pipe and the two bars, Vthe pipe spacing the parts apart the proper distance, i. e., the overall width of the channel and the bolt holding the two bars together and against the pipe. rlhis structure per se is well known and old.

lThe table consists `of two channels 33 back to back and spaced by four pipe spacers 34 so as snugly to slide along the two standards between the bolts 30 and the top of the angles 10 and is heldin place at the desired height by Vinserting pins such as 36 in two or more of the holes 38 in the channels 83 when alined with holes 18 in the bars 17.

Two square shafts 40 and 41 are rotatably mounted in the table one at each side of the standards. The drum 44 is nonrotatably mounted on shaft 40 which carries at its rear a sprocket wheel 45, va ratchet wheel 46, and a handle 47. A pawl 48 pivotally mounted on the web of the channel engages the ratchet endless chain .50,connects the sprocket wheel with a similar sprocketwheel 52 on shaft 41, the latter `carryir'ig a drum 54 exactly similar to the drum 44. y

,At the front the table carries aV guide 60 spaced somewhat away from the web of the channel so as to receive slidably a pair of work supports 60a and 61 carrying respectively, a fixed center 62 and a movable center 63, the brackets with their V-slots and centers being very convenient for test purposes. Chains 64 and 65 are each connected to one of the bolts such as 66, which connect the standards to the vcross'p'ie'ce and are fastened at their other ends to the proximate drum whereby winding the handle 47 will elevate the table while maintainingit constantly parallel to the cross piece, in other words, horizontal. j l

When the table has been elevated toa point just short of the desired position, the handle 47 is released, the pawl 48 holding the two ends of the table lin position. The lmechanic thereupon lpresses in the chain 64 or pulls it `wheelf46 duringelevation ofthe table. An

out, whichever is most convenient, either motion elevating the near end of the table. With his free hand the mechanic inserts-the pinsv 3G thru the holes in the table and in the bars 1T, which are alined Vby the sideways movement of the chainfas just described.

What I claim is l. In a device of the character described, a pair ostan'dards,a cross piece connecting the tops vof the standards, a table slidable along said standards, said table consisting of two channels arranged back to back 'and spaced apart to receive the standards, a drum carried between the Channels 'at each side of the standards, a pawl and ratchet mechanism 'for revolving both drums, avchai'n attached to each drumand extending diagonally to the ltop1 or` the proxirnate standard so that by pushing or pulling on the chain in a horizon- I tal Vdirection the proximate end of the table is elevated, and'means for supporting thetable from the standards.

2. In a deviceof the character described, a pair of standards, a cross piece connecting the tops of the standards, a` table'slidable along said standards, said table consisting of two channels arranged back to back and spaced apart toreceive the standards, a drum carried between the channels at each side of the standards, a pawl and ratchet mechanism for revolvingboth drums, a chain V.attached to each drum and extending diagonally to the top of the proximate standard so thatby pushing Lor pulling on the chain in a horizontal direction the proximate endof the table is elevated, and a plurality of pinspassingthru alined holes in the standards and table `for support-ing the'tabjle.

3. In V'a press table, `a pair of yvertical standards, a horizontal table vslidalole along the standards `and extending to each `side thereof, a drum at each end of the table outside of the' standards, and flexible means connected to the drums for raising the table on the standards while maintaining it in horizontal position, said flexible means being lo` cat edentire'ly outsideof the space between the vertical. standards.

4l. In a press table, two vertical standards each consisting of a pair otspaced rolled steel sections, a pair 'of horizontal rolled steel sections spaced apart to receive between them the two standards and forming a worlrreceiving table extending beyond the standards at each side, and means carried by the sections outside ofthe standards Afor raising and lowering the `table while keeping it horizontal,
