To' all whom it may concern.' I

Be it known that I, FRANCIS K. FAssET'r, a citizen of the United States, residing at St.

`Louis, Missouri, have invented a certain new and useful Improvement in Reversible Gar- Seats, ofwhich the following is a full, clear, and exact description, such as will enable'others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which -Figure 1 is a side elevational view of my Fig. 2 is a sectional View and bottom removed. Fig. 3 is a side elevational View with the seat-back in a central position. Fig., 4 is a vertical sectional view on the .line 4 4 of Fig. 3. Fig. 5 is a detail view showing the upper portion of the seatback-carrying level` and its connections.` Fig. 6. is a sectional .view through said lever. Fig. 7 is a detail View of the lock for the seatback. Fig. 8 is a modified form of rock-arm. Fig. 9 is another modified form of said rockarm.

This invention relates to a new and useful improvement in reversible car-seats, theobject being to simplifyl the construction of seats of this character and also to reduce the'cost of manufatureof said'seats. y

With these objectsv in view the ,invention consists in the construction, arrangement, and combination of the several parts of my device, all as will be more specifically described hereinafter ahdafterward pointed out 'in the claims.

In the drawings, 1 indicates the side frames in the form of castings, which support posts 2, carrying the arm 3 next the aisle. The'post 2 and the arm 3 may be omitted from the seat next .the window; but there is preferably one of the castings 1 at each end ofthe seat. In the following'description'I will refer tol the mechanism located at one end of the seat; but it is to be understood that this mechanism is duplicated at the oppositeA end of lthe seat.y

Mounted upon the supporting-legs of said-casting, is what/I will term the main lever 4, said main lever being pivotally connected at its upper end by means of the pivot-bolt 5to the bracket 6, secured to the lower 'portion of the seatback 7. The pivotal connection between the main lever 4 and the seat-back,l as shown in lthe casting 1, preferably 0nthe cross-piece forming aconnectlon between the drawings, is preferably slightly below the center of the seat-back. The main leverl 4 in addition' to supporting the seat-back also carries foot-rests A8, .said foot-rests being mounted upon the ends of arms 9, extending from opposite sides of the main lever 4 near its lower end. There are several Ways of constructing the upper end of this main lever4in' order to adapt it for its associate parts, and I have shownthree of such constructions in the drawings; but it is obvious that changes other than those illustrated in the drawings could be made without departing from the nature and principle-.of my invention. In the preferred construction illustrated in Figs. 1 to 6, inclusive,the upper end of the main lever 4 is recessed on its inner face, saidA recess being `covered by a tongue 10, riveted to the upper end of the lever and extending down vover said recess to form an inclosed space; The tonguelO'may for all intents and purposes be considered as a part of the main l lever 4, and insome instances the main lever 4 may be cast with a core, so that said tongue n10 will be an integralpart thereof. The

lower end of the tongue 10 carries a pivot-pin l1, on which is pivotally mounted a lever 12, said lever being formed with an opening of slightly-larger diameter than the pivot-pin 11, so as to allowfree `movement of the lever without cramping or binding.- One end of lever, 12 is provided with a projection 13 in the form of a pin or roller operating in a slot 14, formed in the lower end of the bracket-plate 6, which is secured to the seatvback.' The opposite end ofthe lever 12 is provided with an elongated slot 15, which slot receives a pin or roller 16, carriedby a rock-arm 17, mounted .upon a rock-shaft 18, journaled in the upper cross piece of the end casting 1 and extendingthe length of the seat, there being two rock-arms 17 arranged upon the ends of said vrock-shaft.

l'Ihe upper end of each roch-arm 17 is pro` 'vided with an enlarged head 19, having surfaces which are adaptedto engage the mar- 'ginal` iianges or side walls which form the recess in the upper end of the main lever 4. As shown in Fig. 6, this rock-arm 17 is located between the main lever 4 and the lever 12, and

in this manner ,it is possible for the rock-arm 17 .to pass the pivotal point 11 of the lever 12 in reversing the seat.

TOO

The rock-shaft 18 has i for accommodating the sliding frame 22, which frame 22 is provided with dowels 23, which fit into suitable openings in the seat-bottom, whereby the seat-bottom is prevented from becoming displaced with respect to the frame 22. The end castings 1 are provided with upward extensions 1, which serve as abutments for the main lever 4.

The operation of the seat above described is as follows: Should it be desired to reverse the seat from the position shown in Fig. 1, it is only necessary for the operator to take hold of the seat-back and move it to its designed position. The pivotal connection between the main lever 4 and the seat-back 7 is such that the entire weight of the seat-back is carried thereby, and the upper end of the main lever moving in an arc of a relatively large circle it will be observed that the operator has little or no weight to overcome in reversing the seat. The main lever carrying the lever 12, connected to the rock-arm 17, will move said rock-arm, and in the reversing movement the rock-arm will lift the end of the lever 12, connected thereto, and force the projection 13 on said lever 12 to travel down the slot 14. The slot-and-pin connection between the lever 12 and the rock-arm 17 permits the lever 12 to have a small amount of lost motion with respect to the main lever to prevent the lever 12 from being cramped in its movement. In the central position of the seat-back all the parts are in vertical alinement, as shown in Fig. 3. As this position of dead-centers is passed, the projection 13 travels up the slot 14 and reaches the upper end of said slot coincidently with the engagement of the main lever 4 with the abutment 1u on the opposite side of the side frame. During this reversing movement the upper end of the rock-arm 17 is moved up into the housing of the main lever 4, as shown by dotted lines in Fig. 8. This telescoping action is taken advantage of to lock the seat in one of its two positions by an extremely simple locking device, which I will hereinafter describe. The reversal of the main lever 4 also reverses the position of the foot-rests and in addition th`e`roclshaft 18 will, through its arms 20, move the slidingV seat-carrying frames in their curved ways and reverse the inclination of the seat so that the forward edge of the seat will be higher. The object of fixing the arms 17 and 2O to the rock-shaft 18 is to insure a parallel movement of the levers at the opposite ends of the seat. It will be observed that the arms 17 at each end of the rock-shaft move in unison, and consequently the seat-back will not wabble 0r bind in its walk-over or reversing movement. Likewise the arms 20 operate the two seat-bottom-supporting frames 22 simultaneously and avoid binding or cramping of the parts.

While I prefer to have the upper ends of the rock-arms 17 telescope into the housings at the upper ends of the main lever 4, as shown iii the preferred construction illustrated iii Figs. 1 to 6, it will be` olbfvilol'is that on`e` or both arms 17 maybe cut off above the projections 16 and in this manner the housing in the main lever 4 will be unnecessary.

In Fig. 8 I have shown a modified form of levers in which in lieu of the housing for the upper end of the rock-arm I have provided a slot 4a in the main lever 4 for receiving a projection 17 of the rock-arm 17. In this construction the rock-arm 17 operates close tothe inner face of the main lever 4, and the lever 12 is located in a plane between the rock-arm 17 and the slotted bracket-plate G. In order to avoid interference of the pivot 1l with the rock-arm 17 I provide a curved slot 171 in the upper end of the arm 17, through which slot the pivot 11 passes and supports the lever 12 inside the rock-arm 17.

In Fig. 9 I have shown the upper end of the rock-arm 17 provided with a curved slot through which passes the pivot 11; but in lieu of the slot 4l the upper end of the rockarm 17 in this construction operates in a housing, as heretofore described with respect to the construction shown in Figs. 1 to 6.

In order to locl my improved seat-back in its different positions, I take advantage of the telescoping action of the upper end of the rock-arm 17 and mount in the main lever 4 a locking-bolt 24, which bolt consists of a cylindrical body portion having a longitudinallydisposed slot 25 for the insertion of a key 2G. rIhis bolt 24 is provided with a circumferential groove 27, in which are fitted the prongs of the bifurcated end of a leaf-spring 2S, said spring being secured to the main lever 4 and tending to hold the bolt in its inner position. A recess or slot 29 is also provided to receive cross-pins 30, which hold the bolt in its adjusted position, The body portion of the bolt to one side of the slot 29 is removed` so as to leave a locking projection 34. As shown in Fig. 6, this locking projection 34 is in the path of the upper end of the rock-arm 17, and thus it is impossible for said rock-arm to slide up into its housing, and consequently the scat is locked when the bolt is in this position. To unlock the scat, it is only necessary to insert the key 26 until its hooked end engages the inner face of the reduced portion of tho bolt, when the bolt can be pulled outwardly and rotated when the reduced portion gets beyond the cross-pins 30. The locking portion 34 by this rotary movement'I is now placed so as to bear against the outer face of the rockarm 17, and consequently it is possible to move the seat-back to and fro without interference from this locking device. The slot 2S) is deep enough to receive the pins 30 when the bolt is in its unlocked position, and in this way the movement of the rock-arm 17 will not rotate the bolt to a locking position.
