normziil hoiils from n LOO fcrmed with laterally extending spaced horizontal ears 1.6 preferably positioned near the upper and lower edges of the opening in the bracket, while swingingly mounted for horizontal movement between the ears, pref erably at a point medially of its ends, is an arm 17 to the outer end of which the opposite end of the link ll is pivoted. The inner portion 18 of the arm 17 is positioned between the inner a d outer walls of the door 2 and is free to swing forwardly to a limited extent owing to a laterally extend ing lug 19 which is integral with one side thereof and designed to contzurt'with the outer wall of the door 2 when the member 17 has been moved a certain predetermined distance, for a purpose that will presently appear, while movement in the opposite direction is also limited by another lateral lug '20 which extends oppositely to the lug 1t) and prevents for 21rd movement of the arm 1? beyond a certain point, theconstruction be ing apparent by reference to Fig. A lever 21 is swingingly mounted by means of a pintle 22 relative to the inner wall of the door 2 the lower end of the lever lying in proximity to the inner portion 18 of the horizontally swinging arms 17, while the upper portion of the lever 21 has connected thereto one end of a connecting rod 23, the opposite end of which is ope ably connected as at 24 to the upper portion of the bar 25. By this construction a person desiring to enter or leave the cab grasps either of the knobs on the shank 8 for rotating or rocking the shank so that the biflircated bar which is operably arrznged about the depending portion 10 of the bar 25 retracts the latch bolt 4 against the tension of the spring (5. This action moves the connecting bar 23 rearwardly, causing the lower portion of the lever 21 to swing forwardly but will not act against the portion its of the lever 17.

The manually operable mechanism which is positioned near the front seat to be conveniently manipulated by the chauffeur, consists of a. transverse shaft 26 journaled in bearings 27 and has rising therefrom a handle lever 28. An arm 29 is carried by the shaft and depends therefrom and extends 1 1 a direction opposite to the substantially vertically disposed lever 28, while the lower end of the arm has connected thereto one end of a connecting bar 30 the opposite end of which is operatively associated with improved mechanism designed to coact with a vertical shaft 11, when the handle lever 28 is moved forwardly, to swing the arm 13 connected to the shaft as well as the lever 17, which is connected with the arm 13, rear- Wardly causing the inner portion of the lever 17 to move forwardly to act against the lever 21 for the retracting of the catch bolt 4, the lug l9 engaging the outer wall of the door immediately subsequent to the swinging of the lever or arm 21, to limit the movement of the lever 17 and thus exert a pull on the door for the opening thereof.

The mechanism between the rod- 8() and the shaft 11 consists of an arm 32 the inner end of which is keyed to the lower projecting end of the shaft 11, another arm 33 having its inner end bifurcated and loosely arranged about the shaft 11 so that the bifurcated portions 34*. are positioned above and below the keyed inner end of the shaft 11 as shown in Fig. t, while the outer end of the arm 33 is connected as at 35 to the rear end of the connecting rod 30. The for aid face of the arm 33 is positioned normally in uxtaposed relation with the face of the arm 32 so that when pulled forwardly, owing to the contacting relation with the arm 32 which is rigid upon the shaft 11, a rotation of the shaft 11 is effected for the ope *ation of the catch mechanism. An automatically operable clutch or catch, generally designated by the numeral 36, is pivoted intermediate its ends at 38 on the bar 33 for coacting with thebar 32, being normally disengaged from the latter but adapted to engage the bar 32 upon the forward swinging of the bar 5-33, to insure the closing of the door when the handle lever 28 is moved rearwardly. This catch or clutch 36 is designed to be automatically disengaged from the bar 32 immediately preparatory to the final closing movement of the door, so that either one of the knobs may be engaged for rotating the shank 8 for subsequent opening of the door or closing of the same without moving the chauffeurs operating mechanism from a set position. The member 36 is enlarged medially of its ends and provided with transverse openings 37 therethrough for the disposition of the member 36 about the bar 33, while suitable means such as a pin 38, passes through the enlargement and also through the bar for pivotally connecting the member to the bar. A lip 39 is formed on one edge of the clutch member 36 and designed to coact with the adjacent beveled end 40 of the bar 32, and for automatically controlling the position of the member 36, contractile coiled springs 41 are employed and connected to the respective ends of the member 36, while the opposite ends of the springs are connected to a tension controlling element designated as a whole by the numeral 42. This element 42 is constructed in T-shaped form and includes a shank 43, extending from the member 42 intermediate its ends. The springs 41 are connected to the outer ends of the member 42 the latter being piv oted at 4-5 at the point of juncture of the shank therewith to the bar 33, preferably between the point of connection of the bar and the door. The inner portion of the shank 43 is enlarged in rectangular form 01. 4. a person (1% m1 Wit a mt op :11) pa mi howwant, that. when the IUJJnntimMy 0per- .1 ongzwc the arm Of AU. 2 Fail: ct- ()DELQCUECL uni? i-lmsimz 1) i rearwn HQ in :1 lip 57 Gm game in he latch he door 9 0mm 3% and projects 1011 in act against opening a closed normnl posit 7 &0 that its shm v and, set clutvh n'mmbm v i but will be by means 01'? a is uaiion within if-m unjacon; face n'i be nmde'in the; cons wring; 4A; being); 1; "m5; frm'n the prim:
