.Figure il is a detaiLsimilar to that shown in Fig..8 showing the crank` in a downwardly disposed position. a
Figure 12 is a detail taken on line |2l2 of Fig. 2 illustrating one ofthe shoes at the lower ends of the legs. a
Referring now to the drawings wherein like reference characters denote corresponding parts the improved adjustable treatment table of this invention includes a panel i0 providing a table top with hinged end sections i I and I2 and with a pad I3 on the upper surface, a mounting frame having spaced side rails I4 and i5 at one side and I6 and I1 at the opposite side and end rails I8 and I9, a centrally positioned longitudinally disposed shaft 29 having a crank 2l on one end and supporting legs 22 and 23 at one end and 24 and 25 at the opposite end. Y
The end sections i I and I2 are secured to ends of the panel I9 with hinges 26 and 21 and, as illustrated in Fig. 7, the end sections are provided with loops 28 pivotally mounted by bearings 29 on the under surfaces of the end sections and positioned to engage teeth of ratchet bars 39. The loops 28 are provided with counter weights 3lA which are supported on the ends of arms 32 whereby the lower sections of the loops are urged into engagement with the teeth of the Vratchet bars.
As illustrated in Fig. 1 the ratchet bars at one end of the table are mounted on the end rail IB and at the opposite end of the table the ratchet bars are mounted on a cross rail 33 which is spaced from the end. rail I9. As illustrated in Fig. 3, the upper ends 34 and 35 of the legs 22 and 23 are pivctally mounted on a rod 36, positioned in a sleeve 3l that is secured to a sleeve 38 which is slidably mounted on theV shaft 26. The ends of the rod 36 extend through slots 39 and 49 inthe intermediate side rails I5 and l?, respectively of the table frame. The ends of the rod-36 are provided with heads 4l and 42 for retaining the rod in position. The sleeve 31 is also provided with braces :i3 and llibywhich the sleeve 3 1 is supported from a nut 35 threaded on the shaft 29.
The upper ends 46 and 41' of the legs 24 and 25 are mounted on a rod 48 having heads 49 and 5i) lon the ends and the rod is positioned in a sleeve the leg with a pin 6I and pivotally attached, at4
the upper end to one of the side rails of the table frame with a pin 52. l
Each leg is also provided with a caster 63 having a roller 54 therein and mounted on the leg with a clamp 65.
Each leg is also provided with a shoe 66 having upwardly extended ears 51 and 66 with which the shoe is pivotally connected to the lower end of the leg with a pin 69.V The shoes areprovided with a rictional gripping pad 'i9 whereby with the table elevated, as illustrated in Fig. 2 the table is irictionally secured to a floor or the like.
