. 1 v This invention relates to improvements in wheeled tables for transferring invalids.

The principal objects of this invention are:

First, to provide a simplified form of wheeled table or hospital carrier for transporting invalids in which the table or invalid supporting portion is both vertically and angularly adjustable so as to tilt downwardly and depress the side of a'bed for facilitating transfer of the invalid from the bed to the table.

Second, to provide an invalid carrier in which the tilting motion of the table occurs about a pivot located adjacent to the base of the carrier and remote from the free edge of the table whereby a minimum amount of motion of the tilting mechanism results in a maximum amount of movement of the table.

Third, to provide an invalid carrier having a simplified form of vertical adjusting mechanism for the table carried entirely on swingably mounted supports sothat the vertical position of the table can be changed in any of the angularly adjusted positions Of the table.

Other objects and advantages relating to the details of my table will be apparent from a consideration of thefollowing description and claims.

The drawings of which there are two sheets illustrate a preferred form of the table on the carrier.

Fig. 1 is an elevational view from what may be considered the front side of the carrier.

Fig. 2 is a perspective view of the end of the carrier, portions of the upright casings being broken away to illustrate the elevating mechanism and with the dotted lines indicating the tiltedposition of the table.

Fig. 3 is a fragmentary end elevational view partially broken away in vertical section through the driving mechanism for tilting the table.

Fig. 4 is a fragmentary end elevational view of the coupling between the table support and the table tilting shaft, the view being partially broken away to illustrate the operating connection.

Fig. 5 is a fragmentary horizontal cross-sectional view through one of the uprights of the is carried on the uprightsfl l for vertical and Claims. (Cl. 5 86) over a bump or obstruction at the same time 2 tilting adjustment as will be described in greater detail. f

The base I consists of a generally U-shaped tubular member 5 having its open end facing the front of the carrier and having the caster wheels 2 mounted on the underside thereof in any of several well-known methods. Attention is called to the fact that one of the wheels 2A is longitudinally offset from the other wheel 2 on the end of the base so that both wheels will not pass when the table is moved longitudinally. This provides smoother rolling motion of the carrier as it passes over irregularities such as the entrance to elevators. It will further be noted that one of the wheels is provided with a lock 6 for locking the caster in one position for easier steering of the carrier.

The end arms I of the tube 5 are provided with aligned-pivots 8 (see Fig. 2) located adjacent to the rear side of the base and projectin outwardly from the ends thereof. The pivots B are secured to and support the L-shaped arms 9 with the lower branches of the arms projecting forwardly along side of the arms 1 of the base. ihe forward ends of the branches 9 have the se mental racks l0 secured thereto for operative engagement with pinions ll. The pinions II are fixedly secured to the ends of a tilt shaft I2 and the shaft [2 is journaled in the end arms I of the base. Straps I3 are secured to the end arms and positioned in overlapping relation to the pinions II and racks Iii. Backing rollers M are carried onstraps for holdingthe racksrin engagement with the pinions H. The two piece drum-like decorative casing I5 is provided around the pinions and the ends of the racks.

The center of the tilt shaft [2 is provided with a driving gear I6 fixedly secured to the shaft and a yoke I! which has its arm positioned on each side of the gear and apertured to rotatably pass the shaft [2. The base of the yoke I! is bifurcated as at [8 to receive the worm iii in tangential driving engagement with the gear [6. The bifurcations of the yoke are bored coaxially with the worm to receive the lower end of the tilting crank 29 for driving the worm. The upper end of the tilting crank is braced and rotatably supported by the brace rods 22 and a knob 23 is carried by the upper end of the crank.

The upright branches 24 of the L-shaped arms 9 are provided with longitudinalracks 25 on their forward sides and are lapped along the depending posts 25 which support the framework I Of h ta le. 3-; uur he r ps 21. ec red. to: v;

with respect to the branches 24 of the L-shaped arms.

Intermediate of its ends the elevator shafti29 is provided with a housing 3| which encloses a driving gear and pinion similar to the mechanism shown in Fig. 3. An elevating crank 32 extends from the housing 3| and has its upper end secured to the frame of the table 3. Thus rotation of the crank .32 will change the elevation 'of the table with respect to 'the'base regardless of the angular position of the table.

Decorative

rectangular metal sleeves

33 and 34 are secured respectively to the uprights 26 and upright branches 24 enclose the uprights and the elevating mechanism.

From the foregoing description it will be apparent that the forward side of my table may .be pushed over the edge 'of a hospital bed with the front side of the base rolling underneath the'bed. The table 3 can then be lowered into contact with the bed and the front edge of the table then tilted forwardly and downwardly to depress the mattress and springs sothat the table and bed form a trough for facilitating sliding or rolling the patient onto the table. After the patient is placed on the table, the'table' can be raised to horizontal position and the entire carrier pushed to a new position. In removing thepatient from the table to another bed or operating table the reverse process can obviously be carried out.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:
