PHYSIGIANS E'XAMINING TABLE.

Application filed June 10, 1326. Serial No. 114,964.

there should be provided. a step tor the patient to enable the patient to mount the table in a convenient and easy manner. This step interferes with the proper use of the table by the physician after the patient 1s mounted thereon unless it slides out of the way, but it must also be securely locked in its open position against possible shppmg during its use by the patient. My device is adapted to solve these problems and does so in an eilicient and economical manner.

Referring to the drawings Figure 1 is a side view of my complete device. Figure 2 is a top plan view of the lower portion of the same on line 22 of Figure 1. Figure 3 is a side view of a portion of Figure 2 on the line 33. Figure l is a perspective of the complete step.

In the drawings is a base member hav ing longitudinal bars 11 and a front cross bar 12. A top 13 is mounted on a pair of rack bars 1 1 which pass through on either side a pair of gear boxes 14 rigidly mounted on base 10 and which are operated by means of a driving shaft 16 to which is rigidly secured a hand wheel 17 having a handle 18 all of which is usual construction which permits oi: the usual raising and lowering of the top 13. A head member 19 is pivoted in the usual manner at 20 to the top 13 and all? under control of the usual manually adjusted spporting bar 21 which can be raised and lowered as may be desired by means of the toothed ratchet 22 engaging over the cross bar 23 and a rod 2% serves as a guiding rod to prevent aid bar 21 frombeing thrown out of engaging position. A foot support member 25 is pivoted in the usual manner at 26 to the top 13 and by means of the usual ratchet bar 27 engaging cross bar 28 may be adjusted to the desired position.

The foregoing construction is all well known and the operation of the same is in every way usual and the base frame 10 has a rear sloping pair of uprights 29 which through their inward sloping at the upper endjpermit the head portion 19 to be thrown to the lowermost position desired.

A pair of guideways 30 are rigidly curedfto the inside 0t the longitudinal 11 being closed at their inner ends but being supported their open outer ends by cross plates 36. A stop member 31 ing a pair of legs-ii] and casters 33 or": usu: l construction on the lower ends of said legs and also having a bevelled lug 3t on each. side and an inset hook member on each of the inner ends adapted. to hook over the crossbar 12 isused with said base 10.

This step 31 may be entirely removed from the table but ordinarily will be placed so that the bevelled lugs 34 will register in the pair of guideways 30 travelling back and forth therein as the step member 31 pushed in and out rolling upon the casters 33. The inward movement of said step being limited by the engagement of the lugs 34 with the inner ends of the guideways 30 and the outer movement of said step to the full extended position bringing the bevelled edges of said lugs 34 over said cross plates 36 whereby lugs 34: lock said step in the outward position and the hook members 35 prevent the step 31 from being pulled further as they engage the cross bar 12. It is thus seen that in this outward position of this step 31 it is secured against accidental movement being locked between the hooks 35 engaging the cross bar 12 and the lugs 34L engaging the cross plate members 36.

In order to remove the step 31 from the table so as to take it away it is then necessary to tilt the step 31 at its outer end until the lugs 34 are freed oi the cross plates 36 and then pushing back unhook the hooks 35 from the cross bar 12 whereby the step 31 is freed so that it may be taken away. In ordinary usage the step will be left in the mounted position in the chair so that when it is desired to push the step 31 inwardly from its locked position as described it is necessary to tilt the step upwardly at its outer end so that the lugs 34 will ride over the cross plates 36 and pushing in slightly the lugs will then register inside of the cross plates 36 and in the guideways 30 so that the step may be pushed all the way into its closed position and out of the way of the physician using the said table. It is thus clear that the step 31 may be quickly and easily slid back and forth and locked in the full extended position or unlocked to be pushed out of the Way in the encased or closed position.

I claim:

1. In a physicians exai'nining table a slidable step the forWard end of which rests upon the floor, and means for looking it in its extended position.

2. In a physicians examining table the combination of slotted gnideways rigidly mounted on the inside of the horizontal lower longitudinal bars of the base frame of said table, a step having tWo legs mounted on oastors on the front thereof, two hooks at the rear adapted to engage the front cross bar of said table and a bevelled lug on each side adapted to travel in said slotted guideways and ride over and lock against the outer ends of said gnideways.

3. In a physicians examining table the combination of a metallic base. frame, a top adjustable as to height having head and foot portions pivoted thereto and adjustable at their outer ends, slotted guideways rigidly mounted on the inside of the horizontal lower longitudinal bars of the base frame of said table, a step having tWo legs mounted on castors on the front thereof, tW hooks at the rear adapted to engage the front cross bar of said table and a bevelled lug on each side adapted to travel in said slotted guideWays and ride over and lock against the outer ends of said guideways.

4:. In a physicians examining table a slidable step and means for locking it in its eX- tended position comprising hook members on the rear of said step adapted to engage the front lower cross bar of the base frame of said table, slotted guideways rigidly mounted onthe inside of the horizontal lower longitudinal bars of said base frame and a bevelled lug on each side adapted to travel in said slotted gnideways and ride over and lock against the outer ends of saidguideways.

In testimony whereof I afiix my signature.

GUSTAVE A. GALLOWITZ.
