Mycopending application, Serial No. a
1 2 214,932, filed August 23, 1927, describes in detail the portable hydraulic press unit shownincorporated in'the device of the present invention. The press unit' consists essen-r Q tial'ly of acast housing-'2, (Figs. 1 and 2 or L er 4: transforms. this fluid pressure into dynamic force. .A relief valve having an operating) handle 6," is provided to relieve the actuating Wfluidw pressure behind the q A segmental fragment is broken out from the base plate and lower portion of the press plunger 4. The portion of the casting 2. V
forming the hydraulic pressureunit is. of
oblong shape candis oblong in transverse SQOt10Dd1l1G pressure cylinder being formed. along the side of the casting at one end of the oblong section. For a fuller description of the specific press unit, reference may. be, had to the said copending application. The integral bottom of the press unit is extended in all directions to form a circular 7 platform 2" centeringat the center of thelarge press cylinder 2. The radius of the platform 2 is substantially equal to the widthv j of the housing 2; i e. to the length of'the transverse oblong section; so .thatithe hous-zf .mg extends radially from the center to the edge of the platform and forms onereinfore 111g brace betweenv the press cylinder and platform. Reinforcing. braces in i'otherv directions are formed by a pluralityof int egral radial fins'2, which extendina gradual n taper from the headrend of the1cylinder2 Figure 1 is a side elevationof a portable down and out to a slightly raised rim 2 at the peripheryof the platfornr 2 The platform 2 provides a support for the press; and holding means are providedfor holding the platform against movement, to resist the reaction to pressure on the plunger 4. Three radial slots are formed in the circular platform 2 at angles of one hundred and ,twentydegreesto each other; and eachof the threeslots isreinforced alongits edges by a pair ofribs 2?, 2 and 2 formed as continuation of the peripheral rim 2 (see Fig. 5).
F'orbench use, tl1e )latform 2 is simply three long stout bolts 8; and is held spaced from the base-plate by sleeves 9 surrounding the bolts. When a heavy metal base-plate 7 is employed, the bolts may he received -through the slots at 2, 2 and .2 inthe plat-.
form, as shown in Fig. 5, and the work 11 to secured to a base-plate 7, (Figs. 4 and5) by be pressed,- may besupported directly upon, the base-plate 7, or-upon hollow or solid filler blocks 12 resting on top of thebase.
plate. A series of various sized and shaped filler blocks provide for all ordinary uses of the press, and unusual adjustability is pro-v vided for by a series of" different length sleeves to beused in place of or in addition these slots.
to the sleeves 9; longer or shorter bolts 8 being provided as required.
The entire thrust of the plunger 4 is communicated by reaction to the edges 2 2 and 2 of the slots, and therefore the ribs 2 are positioned one on each side of and immediately adjacent to the rims 2 2 and 2 of each slot. It is especially desirableto secure rigidity in a hydraulic press, to reduce resilient reaction to the very high pressurescm ployed. The integral 1 construction and ribbed reinforcing are means to this end;
and, as a further tendency in this direction it is suggested that the total height of sleeves 9 empioyed be reduced not to exceed the requirements of the work normally encounteredfand that the bolts be secured to the 7 is dispensed with, and the press is secured to an ordinary Work bench, auxiliary means areprovrded for supporting the work to be pressed. 'TlllS auxiliary work-holding means is adapted foradjustability alongjand transverselyof the slots at 2 2 and 2 and in order to provide full freedom of adjustabilitv itis'advisable to remove the b-olts8 from Three holes are .drilled,..at 13', 1 1, and '16 in the platform 2" near its periphe ery, to receive the bolts 8. No. special reinforcing need be provided-around these holes. because the auxiliary Work-holding means is adapted to resist all the thrust due to reace.
tion of the plungera; the bolts 8 thenbeing required to bear onl-ythe weight of the press plus thesmall force. exerted upon the pumphandle 3.
The auxiliary work-supporting means is constituted by a'plurality of identical hook-- ended holding bars 17, (Figsl, 2 and 3)..
Normallythree holding bars are employed,
one for each of the slots at2, 2 ,and 2 Each holdingbar is of rectangular section and thick enough to fit non-rotatrvely in oneof the slots, and is provided with a plurality of longitudinally-Spaced transverse pins 18 projecting out on each side of the bar and adapted to ride on top of the raised rims-'2 9 or 2 of the slots.
The bars 17 are adjustablymovable along the slots, and a plurality of transverse grooves (see Figs. 1 and 5), 1s provlded 1n the rims 2, 2 and 2 for receiving the pins 18 of sa d bars to form pivotal joints between the supporting plate 2" and the bars, and so provide non-positive means for retaining the bars-in adjusted position along the slots, while permitting pivotal accommodation thereof to hold objects of slightly varying sizes or irregular shapes.
The hooked ends17 oft'he bars are substantially in line with the centers of pins 18 so that it is practically impossible to move the bars when a work piece 11 (Fig. 1) is held under pressure. As soon as the pressure is released the bars may be lifted slightly and moved along the slots to fit work pieces ofdiiferent sizes, or may be Withdrawn from the slots and reinserted with pins 18 of different elevation resting on the rims 2 2} and 2?, to effectively shorten the holding bars;
The bars, of their own accord, assume a vertical posit-ion, and-being non-rotatable in the slots, are. always in position to receive a work piece. same size are being pressed, separate. manual manipulation -of each bar is not required each time a work-piece is inserted. It is merely necessary to insert the work piece from be low. Of course the bars may beremoved from their slots. and'reversed so that their hooked ends point outwardly instead of inwardly, for holding. the rimof a spoked Wheel at its annular-internal circumference.
A fourth-slot exactly similar to the slots at 2 2 and 2 is provided at 2 opposite to and in line with the slot at 2 (here it is inexpedient to use three-point support, as whena long narrow bar is being pressed at its center, then bars 17 are used only in the two. aligned slots 2 and 2 7 An important. feature of the press. of my inventionisits adaptability to use as a portable tool, for example, in disassembling small portions ,of automobiles orother large machines. "The structure afore-describedis universal in that, by: merely removing the press from itsthree-holdingbolts 8, it may be taken to the Work and heldinoperative osition thereagainst by the samehook-end-ed hold.- ing bars 17. As set forth in my copen-ding applicationSeria'l No. 21 h932, above referred to, the press may be operated with equal facility' in any posit-ion. of angularity.
In order to; retain the bars L'Zin adjusted position along the slots when: the press is 011 its side or upside down, fiat springs 19 (Figs. 1 and; 2*); are provided, one above each rim 2*, 2, 2 and 2. The springs are secured at their inner ends to; the top. centralpart of the platform 2 and extend to near the edge thereof beingspaced above the platform to permit insertion of the bars with their protrudin pins. 18;. The springs bear down upon t e pins 18 and urge them against the grooved; rimsQ", 2-, 2 3,01 2.
Each spring 19is supplemented by a backing spring 20iconsisting of a slightly bowed spring bar secured to. the. vertical surface of: thefcasting 2,v and extending down into 1 pressure contact with the spring 19 near the.
lVhen successive work pieces of the e ion outer. end? thereof. Thej springs 20' are not I ever, that each spring 19 is preferably backed by a supplementary spring 20.
As a further means to hold the bars 17 in position ready to receive a work piece regardless of the angularity of the press, the projecting portions of the pins 18 are cut half away to leave a flat top surface inclined, but very slightly, from the horizontal downwardly toward the hooked sides of the bars 17. When the flat springs 19 press upon the'flattened tops of the pins 18, the tendency is to hold the bars in neutral position, nearly perpendicular to the plate 2* butinclined very slightly with their lower ends nearer center. v
Assuming that the press is to be employed in a horizontal position to pull a line-shaft pulley, the press may be held in one hand, leaving the other hand free to operate the pump handle 3. It is unnecessary to individually hold each bar 17 until the pulley has been placed under pressure. Of course, after the pulley has been placed under pressure, the press is tightly held to the pulley, leaving the operator with one hand free While pumping the lever 3 with the other hand.
The device of my invention is universal in that it is applicable to use as a fixed or movable bench tool or as a true portable press.
said bars adapted tosecure articles in operative relation to said ram, and cooperating means on said bars and platform for restraining said bars in adjusted position along said slots. V
. 1. In a press, a platform having a plurality of slots therein, a pressure ram movable through an opening'in said platform, a plurality of'bars movable along said slots and adapted to be supported by said platform,
holding hooksonsaid bars adapted to secure 7 7 articles in operativerelation to said ram, and cooperating means on said barsand platform for restraining said bars in adjusted position along said slots while permitting pivotal movement of said bars.

and 20 is chiefly supplemental to the elfect of gravity. If desired the springs may be removed. In general, however, it will be advantageous to leave the springs in place so that the press may be moved from the bench and used as a portable tool by merely removing it from the holding bolts 8. In order to simplify the drawings, the bolts 8 have been omitted from Figs. 1 and 2, and the springs 19 and 20 and holding bars 17 have been omitted from Figs. 4 and 5.
I have described one embodiment of my invention in detail, but it is emphasized that i this embodiment is illustrative, and not in elusive of all the forms my invention may assume. Certain of the objects, or certain portions or combinations of the objects of my invention may be attained with the use of less than all its advantageous features or modi fications within its purview. It is petitioned that my invention be limited only by the claims constituting its final determination.
I claim:

hydraulic pressure unit mounted integrally on one side of said platform, and holding means adjustable along said slots on the other 7 side of said platform, said slots extending out-
