Application filed March 22, 1926.

The present invention relates to an improved form of handle for use in the manual operation of gates or doors, and more particularly to such as are employed in connecy tion with the toggle levers commonly used in opening and closing elevator doors of the sliding type or folding gates constructed on the lazy tongs principle.

In the operation of elevators in hotels, oflice buildings etc. the employee employed on the elevator cage is obliged to open and close the door or gate hundreds of times a day and it is therefore highly desirable to provide a handle of such a character as to minimize the discomfort'and fatigue inci dent to this task. Moreover, as this art develops the demand for aesthetic design in equipment is constantly increasing.

The form of handle which forms the subj ect matter of this invention is therefore intended to contribute to a diminution in fatigue and discomfort in use as well as to improvement in appearance.

Another object of the invention is the provision of safety againsthurting the hand or fingers of the operator, particularly where folding gates are used, in which the fingers may be accidentally pinched between the bars of which these gates are constructed The invention is illustrated in a preferred form in the accompanying drawings, wherein Figure 1 is a view in elevation of a twopart sliding or hanging elevator door equipped with our improvement, Figure2 is an enlarged view of our improved handle seen in front elevation, and Figure 3 is a View of said handle in vertical section.

In Figure 1, the two sections of a sliding elevator door are shown at 10 and 11. These are suspended from brackets-l2 which roll in a well known manner upon the rail 13. As shown, these are in the closed position, in which they are locked by the usual toggle lever system. This latter comprises a middle lever 14, pivotally supported upon the door 10 at 15, and two end levers 16 and 17. The former of these is pivotally attached at one end to the door frame at 18. and at the other end to the middle lever 14 at 19. The end lever 17 is pivotally attached to the lever 14 at 20 and at its opposite extremity is similarly attached to the door 11 at 21.

DOOR-OPENING HANDLE.

Serial No. 96,395.

The handle whereby these toggle levers are operated in opening and closing the doors is shown at 22, being fixed to the middle lever 14 near its attachment to the end lever 17.

with any desired form of checking means or combined door closing and checking means.

In the form shown in the drawing the closing and checking means is shown at 23, being operatively connected with the end lever 16 by the arm 24 and the bar 25, this latter being pivotally connected with the arm 24 and the lever 16 respectively. As these form no part of the present invention, they will need no further description. I

The structure with which our invention is concerned is shown in detail in Figures 2 and 3.

This comprises a rounded gripping bar 26 substantially parallel to the toggle lever 14, whose

ends

27, 28 extend inward to join the base portion 29 utilized for the attachment of the handle to the bar 14.

The base 29 has a flat extension 30, which, together with the fiat shoulder 31 at right angles therewith, forms a recess which fits the bar 14 in the manner shown in Figure 3.

A finger guard 32 fits the back of the base 29, and extends downward to form a smooth pocket 33 which accommodates the operators fingers and effectually shields his hand from any accidental contact which might prove injurious.

The base 29 and the shield 32 are united either integrally or in the manner illustrated and are fixed to the bar 14, preferably by means of the rivets 34 or their equivalents.

The gripping bar 26 and shield 32 are so shaped and proportioned as to be accommodated to comfortably fit the operators hand and at the same time to prevent any possi bility of exposure to accidents.

What we claim is- 1. A handle for manipulating doors and gates comprising a rounded gripping bar, a

base to which the same is fixed and a shield on said base, said shield being curved so as to form a pocket adapted to shield the ends base, and a finger shield on said base and of the fingers when in normal position to curving toward said bar in a position to 10 grip said bar. shield the ends of an operators fingers.

2. In combination with a toggle bar for In testimony whereof we have hereto af operating doors or gates, a handle base havfixed our signatures on this 20th day of ing an extension fixed to the bar forming a March 1926. recess in which the bar is fitted, a rounded HAROLD W.
