LEVER.
T o all w hom t may concern.'
Be it known that I, FREDERICK D. WVILsoN, a citizen of the United States, residing at Moline, in the county of Rock Island and State of Illinois, have invented certain new and useful Improvements in Levers, of which the following is a specification, reference being had therein to the accompanying drawing.
My invention relates to levers commonly employed for adjustment purposes, and the object of my invention is to provide such a device with a novel and effective means of holding the lever at any point of adjustment.
' Referring to the drawings in which similar numerals indicate identical parts- Figure 1 is a side elevation of my improved device.
Fig. 2 is a front elevation in part section.
Fig. 3 is a front elevation in part section and showing the lever released for operation.
Fig. 4 is a detail in part section showing the lever in engagement with a tooth of the sector, and
Fig. 5 is a detail of part of the lever.Y
On a support 1 is rigidly secured a sector 2. A lever 3 is pivotally supported on a bolt 4t which passes through the support 1 and the base 5 of the sector 2; on the free end of the lever 3 is the usual grip 6. Slidably mounted on the lever 3 is a casting 7 having a part 8 which extends above and to the side of the arc of the sector 2 opposite the lever 3. Preferably integral with the part 8, and extending downwardly therefrom, is a projection 9 having its inner face beveled to contact with a similar bevel 10 on the adj acent edge of the arc of the sector 2. On the lever 3, above the casting 7, is rigidly secured a member' 11 between the under side of which and the top of the casting 7 is a coiled spring 12 held secured in place by a stud 13 on the member 11 and a similar stud 14 on the part 8 of the casting 7.
On the side of the arc of the sector 2 opposite the bevel 10 is a series of radially disposed teeth 15 any one of which is adapted to engage with a slot 16 in the lever 3. EX- tending from one side of the part 8 of the casting 7 is an eye 17 in which the lower hook end of a rod 18 is engaged; the rod 18 extends upward and is connected to a Specificationof Letters atent. Patented Sept, 20, 1921- Application led October 3,A 1919. Serial No. 328,227. y y
vAs shown in Figs. 1 and 2 the lever 3 is held in position by oneof the teeth 15 of the sector 2 engaging with the slot 16 in the lever, and the pressure of the projection 9 against the bevel 10 of the arc caused by the expansive force of the coiledv spring 12. When it is desired to swing the lever 3 to a different position the two grips 6 and 19 are brought together raising the casting 7, and as the latter raises lateral pressure Vis exerted by the operator to spring the lever 3 outward from the arc of the sector 2 to free the slot 16 from the tooth 15 with which it has been engaged. j When the lever 3 is free to be rocked either forwardly or rearwardly the parts are in position, as shown in Fig. 3, the end of the projection 9 having the limit of its upward movement below the upper edge of the are, acts as a stop to prevent the lever 3 from too great a lateral movement.
When the desired position of adjustment has been reached it is obvious that when the operator releases his hold upon the lever 3 the latter will spring back into place, the slot 16 engaging with the tooth 15 opposite to which the lever 3 has been moved; simultaneously with the spring of the lever 3 back into position, thek casting 7 will move downwardly under pressure of the spring 12 until the parts are as shown in Figs. 1 and 2, the bevel of the projection 9 resting firmly against the bevel 10 of the arc and holding the lever 3 securely in place.
What I claim is 1. In a lever mechanism, the combination of a sector, a lever pivotally mounted to rock lengthwise of the sector, means on one side of the arc coacting with means on the lever to hold the latter from rocking, said means separable by springing the lever laterally whereby the lever is free to be rocked, and means on the lever in contact with the other side of the arc to hold the lever from lateral movement, said means adapted to be raised to free the lever simultaneously with the lateral swing thereof.
2. In a lever mechanism, the combination of a sector, a lever pivotally mounted to rock lengthwise of the sector, teeth on the side of the arc adjacent the lever, said lever provided with a slot to engage with any one of said teeth to hold the lever from rocking, and means on the lever in contact with the side of the are opposite the lever to hold i 'the ylatter from lateral movement, said means adapted to be raised to free the lever Sifrnultaneously with the lateral swing thereo 3. In a lever mechanism, the combination of a sector, a leverpivotally mounted to rock lengthwise of the sector, teeth on the side of the arc adjacent the lever, said'lever provided with a slot to engage with any one of said teeth to hold the lever from rocking, a bevel on. the opposite side of the are, and a casting slidably mounted on the lever and having `a downwardly extending projection lin Contact with the bevel of the arcrto hold the lever from lateral movement.
4. In a lever mechanism, the combination of aA sector, a lever pivotally mounted to rock lengthwise of the sector, teeth on` the side of the are adjacent the lever,said -lever provided with a slot to engage with any one of the teeth toV hold the lever from rocking, a bevel on the opposite side of the are, a casting slidablymounted on the lever and having a downwardly'extending. projection a bevel on said projection in Contact with the bevel on the are to hold the lever from lateral movement.
5. In a lever mechanism, the combination of ka sector, a lever pivotally mounted toA abevel on said projection 'in contact with the bevel on the arc, a member rigidly secured -,on vthe lever, and -a vcoi-led spring interposed between said'member and the casting to hold the bevels in contact whereby the lever .is held from lateral movement.,
