To all whom it may concern:

Be it known that I, HARRY T. COLDWELL, citizen of theUnited States, residing at New burgh, in the county of Orange and State of New York, have invented certain new and useful Improvements in Speed-Controlling and Reversing. Apparatus for Motor- Vehicles; and'I do hereby declare the following to i the accompanying drawings which illustrate the best form in whichI have contemplatedembodying it, and said invention is fully disclosed V in the following description and claims.

The object of my present invention is to provide a very simple and etiicient controlling apparatus for motor vehicles and the like, capable of use with the more ordinary form of change speed gearing now in use, and which is provided with means for preventing a change of speed or direction without first releasing the ordinary engine clutch, and also with means for locking the control lever in position laterally to .-,throw in any selected gearing, and with means for further locking the leverlongitudinally in the operative or inoperative position with respect to the selected gearing.

In the accompanying drawings I have shown my invention in connection with a passing through sliding gear change speed and reverse mechanism in ordinary use, but it is not limited in use to this particular form of gearing as variations may be made therein. For example in the form of gearing here shown, a single push rod controls the gears for three speeds ahead, and reverse, but my invention is equally applicable to gear mechanisms providing less or more speed changes, and also to those in which the reversing of the driven shaft or shaft section is effected by a separate rod or device as hereinafter explained.

Referring to the accompanying drawings. Figure 1 represents a sectional view of my control apparatus in its simplest form, adapted to be applied to a form of sliding gear change speed-mechanism in which the gear changesforspeeds ahead and reverse are c complishediby, a single instrumentality. Fig. 2 is an enlarged plan view of theguiding plate for the control lever, shown in Fig. 1. Fig. 3 is a detail sectional view of a; form of change speed mechanism with which my invention can be advantageously employed, and in which all changes for speeds ahead and reverse are effected by the movement of a single instrumentality. Fig. 4 is a sectional View on line 4-4 of Fig. 1. Fig. 5 is an enlarged plan view of the locking plate detached. Fig. 6 is a plan view of a modified form of guiding plate for the controlling lever. Fig.

7 is a plan view of the locking plate used in connection therewith. Fig. 8 is a plan view of another modified form of guiding plate.

'Fig. 8 is a detail sectional view of one of the pivoted latches. Fig. 9 is a plan view of the locking plate used in connection therewith.

Fig. 10 is a detail view of a slight modification showing the lower end of the lever, and a separate shifting rod for the reverse gear. Fig. 11 is a detail of a modification of my invention. Fig. 12 is a detail plan view of the locking plate for preventing the progressive movement of the shifting lever to throw in ahigherspeed, without releasing the clutch.

In Fig. 3 I have shown a type of change speed gearing in which A represents the gear casing, B the driving shaft, and B the driven shaft. Shaft B is connected by universal-joint C (or otherwise) with the driving mechanism of the vehicle. E represents the engine or motor shaft and D is the usual clutch for connecting the engine shaft with the driving shaft B. The driving shaft B is provided with pinions 1, 2, 3 and 'rigidly secured thereto and the pinion l meshes with an idle pinion 5 mounted on a separate stud. On the driven shaft B which is preferably squared is mounted a sl ding sleeve B rotatable with said shaft member and carrying the gears 63, 7 and 8. F represents a sliding bar or rod mounted in the gear case A and carrying a yoke 7' which engages the sleeve B for sliding the latter on shaft B. The rod F is preferably provided with an arm or lug 7" extending upwardly therefrom and preferably having a transversely disposed head f round in cross section, secured to its upper end. G represents the controling lever which is mounted pivotally in a suitable standard or casing G, so that it can be swung both la erally and longitudinally. prefer to pivot the lever between its ends a bl ck r ly'means of a pingrthe said lock laving gudgeons. g ,9? engaging apertures 1n the casmgGr. thus. mounting the lever practically on a universal joint. The

lower end of lever (r provided with a yoke.

, portions eonneriedhv transversely disposed portions. so that the lever G cannot he moved troni one .longiuidnial POl'i'l'Ull to another without moving it: laterally.

In the form shown in Fig. 2. there are four longitudinal portions. 71. /z. lz ii. of which 71, and l are in line with eaeh other and 1'1 and it. are in ali'nenient. il' hen the lever is at the rear end oi? the portion A of the slot. as shown in dotted lines Fig. it.- will he in neutral position. To throw in. the firstv or slowest speed the lever pushed forward to the end of the portion a, to throw in second speed. the lever is moved laterally. into line with the portion i2? and then pushed forward to the end of said portion 1 to throw in third speed, the lever is moved laterally into portion '5 and thrown forward. The effect of the first of these "lllOVQlllQlllS' in setting the gears for the first speed forward is to slide the rod )3, yoke f. and sleeve 13" rearward and to bring the gear 6 into mesh with pinion .2; the further move ment of the lever in setting the gears for see- 0nd speed moves the sleeve B further so as to bring gear 7 into mesh with pinion 3. and

the high speed is elieeted when the lever is moved to its extreme position in slot section 11 by a further movement of the sleeve B to bring gear S into mesh with pinion -l.

In order to reverse the vehicle, sap-posing the lever G to be in its neutral position as shown in Fig. 1 and in dotted lines Fig. 2, the lever is, thrown to the rightv into slot section h and then rearwardlyto the end of the slot, thus moving rod F in the opposite direction to that above described and hringiig gear 6 into mesh with the idler 5. which i preferably made with a broader face than t e gear (301' pinion 'l, as shown to faeiliiate this operation. I also provide means for locking the lever G in position at eaeh end of each .of the slot sections i1, 71. 11 .71 In this'instanee l have shown plate l'l provided with detents l1 /1' at each end of each of said. slot sections. adapted to he engaged by.

Z. 7. as showrrin l iggj. 'e". wise the entire eonstrnetioie will he exactly as previously described. and will operate in the same way.

In Fig. 3% l have shown another sli' nioditied form of the guiding plate. in slot sections it and la. for the reverse and first speed positions are arfanejed live with eaeh other. the other slot, seetions and i1 heing: progressively in se'piirate line-s from ear-h other and from slot sections 72' and 11. as shown. in this ezse l eonvenientlv provide a pair of pivoted taps or latches la 71- mounted on the plate iii. and adapted to lie aeross the alined slots 71 and 71. so as to separate the same and prevent operator from coming on. of first speed reetl'y into reverse. or vice; versa. "Ruse latches or flaps are connected in such a "iiii that only one can lie across the slots a drive.

time, the other being held vertical. In this instance I provide the hinge portion of each flap with a stud H (see Fig. 8 engaging an aperture in one end of a lever it pivoted centrally to the under side of the plate H which is slotted to permit the studs [L7 to pass through the sameand engage the lever.

d Hence when one of these flaps is raised the lever it will be shifted so as to throw the other flap into horizontal position. In case the plate shown in Fig. 8 is used. the locking plate must be modified to correspond by providing it'with three locking apertures Z, Z Z as shown in Fig. 9. otherwise the construction and'operation will be exactly as previously described.

In some cases the change speed and reversing mechanism may be so constructed that separate instrumentalities may be required for the forward speeds. and the reverse. In Fig. 10 I have shown a slight modification of my controlling device, to meet this. condition. In this figure F represents the rod for. moving the gears .to effect the changes of speed forward. and F 2 represents a separate rod suitably connected with the mechanism to effect the reverse The rod F is provided with an arm having the transverse h'ead f similar to that previously described and rod F has a similar arm haying a head f in line with the head f Obviously the lateral movement of the lower end of the'lever here lettered G from. its neutral. to the right will cause it to release the main head f and engage the head f, when the reversingmechanism can be thrown into and out'of operation. This form ofimech'anism as shown in Fig. 10 -can be used with a guiding plate, such as is shown in Fig. 6 for example, or similar to'that shown iii-Fig. 1 as may be, preferred. i

In Figs. 11 and 12 I have shown a modi= fication of my invention for the purpose of locking the lever so that after pulling the lever in a direction to disengage the gears for a certain speed. it" will beimpossible to return to that speed without first releasing the clutch! In Fig..11 a v ew is shown similar to Fig. 1. in which G represents the shifting lever and F the-shi ting rod connected with the sliding gear gears and L is the locking plate, all as /previously de scribed. In this instance I have shown the bolt M for engaging the locking plate, carried on 'the end of one arm of a bell crank lever'M the other armofwhich is perforated to receive a draw rod connected with the clutch lever I The operation of the plate L" is identically the same as that of the plate L previously described.

lt representsadaterally movable locking plate. \vhi'chI term the latch plate-to distinguish it from l'o'ckingplate L. This latch plate R is preferablypivoted at one end, and

is provided with a. series of teeth 9', W, T each having a straight face and an inclined fate, as shown in Fig. 12. In this figiire the dottedf lines indicate the-path of the positions to high speedythe lever being guided in such movements by theplate H shown in detail in Fig. The latch plate R is held in operative position by spring 0", and'is connected. as by rod 1' with the clutch 1 so as to be moved laterally when the clutch lever is pressed forward in the direction of the arrow to release the clutch. \Vhen the lever G is in neutral position the straight face of the tooth or shoulder 7" lies directly in rear of the lower end of said lever. so that the lever cannot be moved to throw in the first speedgwithout first throwing the clutch out. thereby moving the latch plate laterally and disengaging the shoulder r from the lever. G laterally in line with the second speed notch (Fig. 2) the shoulder 1- will prevent the second speed gearing being thrown in except while the clutch is out, and in like manner shoulder 1 prevents the passing from second to third or high speed except when the clutch is out. lvhen the lever is in neutral position (Figs. 2 and 12) and is swung laterally in line with the reverse slot. the reverse gearing cannot be thrown in, unless the clu'tch is out. as the shoulder 7- prevents the movement of the lever G to effect such change. The inclined faces of the shoulders or teeth 1*. 1' '2" permit the operator to pull the lever G out of reverse, to neutral, from first speed to neutral and from a higher speed to a lower, .without throwing out the clutch. if it is desired to do this quickly but will effectually prevent the throwing in of reverse. or first speed, or any higher speed without first disengaging the clutch. This latch plate may be used in connection with other forms of gearing than that herein shown. as for example selective gearing, by suitable modification and it may be used with or without the locking plate I1 01 In. I The controlling mechanism herein shown is'adapted for use with any form of .-hange speed and reversing mechanism having any desired number of speeds forward or reverse. 'lVhile I have shown a particular form of change speed and reverse mechanism herein for the better understamling of my inven tion such change speed and reverse mech anism forms no partof my invention and the invention isnot limited to use in connection therewith.
