Specification of Letters Patent.

Patented Sept. '7, 1909.

Application filed August 7, 1908. Serial No. 447,394.

To all whom it may concern:

Be it known that I, MYRON RoUNDs, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented new and useful Improvements in Convertible Cars, of Which the following is a specification.

This invention relates to improvements in convertible cars, that is, in a car in which it is desired to change the same from a closed to an open car. To accomplish this the sides of the car are closed by means of a series of panels which are adapted to be dropped into panel receiving chambers and a series of sashes, preferably an upper and a lower sash, said upper and lower sashes being adapted to be moved upwardly into a sash receiving chamber in the roof of the car.

The invention consists in improved means whereby the two sashes may be raised together and held locked together in the sash receiving chamber in the roof of the car.

The invention further consists in the combination, with the sashes, of a sash balance so arranged with reference to the sashes that the means connecting the sash balance to the sashes pulls at an angle to the sashes when they are in their closed position and thus assists, when the sashes are raised, in tipping them to an inclined position in the roof.

The invention further consists in a holder adjacent to the lower end of the sash chamber which extends longitudinally of the car and is adapted to receive the lower end of one of the sashes and hold said sash, when said sash is in its inclined position within the sash chamber.

The invention furtherconsists in the construction of the guideways for the sash and the relative location of the sash chamber thereto, the lower corners of the lower sash being cut out, as hereinafter described,

whereby a straight post may be used and the guides for the sash made parallel from the arm-rail to the top of the upper sash, the lower end of the chamber for'thesash terminating substantially at the top of the upper sash, so that the projection of the sash chamber is very slight and is located above the top of the upper sash, as well as the curtain roll, the advantage derived from this construction being that the curtain roll and the inner wall ofsaid chamber do not project over the seat in the car below the top of the upper sash when said upper sash is in the position indicated in Figure 2, so that when a person rises from the seat there is no danger of the head or hat of the person striking the casing which surrounds the curtain roll.

The invention consists finally in the combination and arrangement of parts set forth in the following specification and particu-- larly pointed out in the claims thereof.

Referring to the drawings: Fig. 1 is an inside elevation, partly in section, of a portion of one side of my improved convertible car. Fig. 2 is a detail sectional elevation taken on line2-2 of Fig. 1, looking toward the right in said figure. Fig. 3 is an enlarged section taken on line 2-2 of Fig. 1, illustrating a portion of the sash chamber and the sashes, the lower sash being partly raised. Fig. 4 is a detail sectional elevation of a portion of the upper and lower sashes, a portion of the post being shown in connection therewith in section, on line 44, Fig. 3. Fig. 5 is a sectional plan taken on line 55 ofFig. 3. Fig. 6 is a section taken on line 6-6 of Fig.3. Fig. 7 is a detail elevation of one of the posts. Fig. 8 is a section taken on-line 88 of Fig. 2. Fig. 9 is a section taken on line 99 of Fig. 2. Fig. 10 is a section taken on line 1010 of Fig. 2. Fig. 11 is a perspective View of one of the lower corners of the lower sash.

Like numerals refer to like parts throughout the several views of the drawings.

In the drawings, 12 is the roof of the car, 13 the side and 14 the floor. In the side of the car are a series of posts 15, 15 which have openings l6, l6 therebetween and each of these openings is closed by an upper sash 17, a lower sash 18 and a panel 19. The panel 19 extends across the space between the posts immediately above the floor and rests,

when closed, upon a base-board 20 in the side of the car. When it is desired to lower this panel the same is slightly raised to clear the lip 21 and is then lowered into a recess 22 inside the base-board 20. The lower sash 18'rests, when closed, upon the window stool 23 and is locked in its closed position by means of spring bolts 24,- 24 which are adapted to spring into recesses 25, 25 in the post 15 and thus lock the lower sash either in its closed position or partly open in a manner well known to those skilled in this art. The upper sash is also adapted to be or guides 29- and. 30.. The stop head 30 is discontinued at the bottom of the upper sash when: said upper sash is in its closed position, as in F 2,. and said upper sash is Y guided.- on the outside thereof by the guidestrip 31. The upper sash 17 has brackets 3% fast thereto w rich extend upwardly from: the casings of the spring bolts 26 and these brackets extend outwardly over or across the top of the lower sash 18, so that when said lower sash is raised, as illustrated in Figs.v 3 and l,-.the upper edge of the lower sash will abut against the under side of the bracket arms 3st, 34 and the two sashes l7 and 18 will then move upwardly together. The lower sash has spring catches 35, 35 upon its; upper edgeand each of thesespri-ng catchesis normally held in the position illustrated in Fig. a, so that when the lower sash is raised the spring catch will be out of ali-nement with the bracket arm 34, but assoon as the two sashes have been raised a slight distance together then the spring catch is carried toward the side of the lower sash by a spring 36 and the hookedcatclr then passes. over the bracket arm 34..

This looks the upper and. lower sashes to each other so. that one cannot be moved without the other, and this locking occurs during the raising of the lower and upper sash, at the time when the outer end of the catch moves down the incline 37 formed in the post 15.. locked together and when the sashes are lowered the reverse movement will take place and the spring catch 35 will be thrown out soon as the spring catch rides up the incline 37 in its downward movement.

A sash receiving chamber 38 is located in the roof of the car, said roof forming the upper and a portion of the outer wall of said chamber, the inner wall '39 of said chamber extending at an incline from the roof downwardly to a point substantially on a level with the top of the upper sash when the up per sash is closed, the panel 39 forming the lower portion of the outer wall of the chamber 38. This chamber 38 is adapted to receive the two sashes when they are raised therein-to. and placed in an inclined position therein. To assist in this raising of thesashes a sash balance 40, well known to those skilled in this art, is provided, said sash balance being connected by a chain 4:1 to the Thus, the two sashes are I lower sash 18.

The chain ll is connected at itstwo ends to the sash balance and extends in U form around the two sheaves or guide pulleys 42, -l2- which are rotatably mounted upon the upper end of the lower sash 18. Said chain is further guided by a guide-roll 4-3 suitably journaled in its opposite ends in plates 4%, l4: fast to the posts 15, and these guide-rolls bear against the opposite sides, respectively, of the lower sash, as

. the sashes are being raised into-the sash chainiber, as hereinbefore set forth.

The upper edge of the sash 18 engages, as the sashes are raised into the sash chamber, ribs l7, i7 '111 the upper portion of said sash chamber. When the sashes are 111 their inclined )OSltion, as indicated. in- Fig. 2, in dotted lines,

-in the sash chamber, the lower end of the sash I8 rests in a holder 458 which extends I longitudinally of the car and is fastened to the outside thereof beneath the letter board or panel 39, so that it may be easily remored. The holder 48 also serves to shed therain and divert the same from the windows.

A. curtain is attached to a spring-curtain.

. roll 50 journaled in suitable plates fastened vbe dropped for the purpose of ventilation.

The stop beads 29 are made in two parts 29 and 29 the part- 29 being fastened to the posts 15 by means of screws 52 (Fig. 9)

and these screws extend through slots 53 in said stop beads and are screwed lnto the posts 15. so that by loosenmg said screws ithe stop bead may 'be adjusted and pressed closely against the lower sash, a strip of felt 54 being preferably supplied upon the .inner edge of said stop beads in order to .make a tight joint in cold weather. :beads 55 are also supplied, fastened to the Stop posts to assist in guiding the panels 19 .into the recesses 2.2- when said panels are dropped in order to make the car an open car. of engagement with the bracket arm 34L as i The operation of' changing the car from a closed to an open car 1s as follows: Assuming: the parts to be in the relative positions illustrated in Figs. 1 and 2, the panels 19 are raised until the lower edge thereof clears the lip 21 and are then pushed inwardly and dropped into the recess 22, thus opening all of the space between the post from the lip 21 to the arm rail 57. The bolts 24, 24 upon the lower sash are then pushed backwardly out of the recesses 25 in the posts 15 and said lower sash is then pushed up until the upper edge thereof abuts against the bracket arm 3-1. The two sashes 17 and 18 will then movetogether and after they have been moved up a slight distance the catches 35 will slide down the incline 37 and over the bracket arms 34,. 34,, thus locking the upper and lower sashes together relatively to each other. The catches 35 and the bolts 26 will then slide along the recessed portion or groove 33 until they pass out of said groove into the open space 58 located thereabove at opposite sides of the sash chamber 38. The upper edge of the lower sash 18 will then contact with the ribs 47, 47 upon opposite sides of said sash chamber and upon pushing the sashes still farther upwardly they will be tipped to an inclined position and; will fall over upon the springs 59 fast to the wall 39 upon opposite sides of said sash chamber. The sash balance 40, during this upward movement of the sashes, willpull thereon at an angle thereto through the chain 41. The lower edge of the upper sash 17 is rounded off at 17 to clear the wall 39 of the chamber 38, as the sashes are being tipped into the inclined position aforesaid. The lower sash 18 is cut out at 18, 18" at its lower corners on opposite sides thereof, as illustrated inyFig. 11, in order that said window at its opposite lower corners .may clear the guide-strip '31 when being tipped into the inclined position aforesaid. Finally after the sash has been raised to its highest point in the sash chamber the same is allowed to drop and the lower'end of the sash 18 will enter the holder 48, as shown in dotted lines (Fig. During the first part of this upward movement of the sashes the inner faces of said sashes, upon opposite sides, will bearagainst and be guidedby the guide- rolls 45, 45 and during all of the upward movement of said sashes hereinbefore described thechain 41 will be pulling inwardly upon the upper end of the sash 18 so as to tip the same into the inclined position indicated in dotted lines '(Fig. 2).

In reversing the above described operation, to make a closed car of the open car, the panels 19 are drawn upwardly out of the recess 22 and the. lower end thereof slipped over the lip 21, as shown in Fig. 2. The sashes are then raised slightly until the lower end of the sash l8 ismoved out of the holder 48; then the sashes are dropped'and as the spring catches 35 arrive opposite the incline 37 upon the posts15, said spring catches will be pushed toward each other or away from their respective posts until said catches disengage. the bracket arm 34. The spring bolts 26 will stop the downward movement of the upper sash17 when said upper sash has arrived in the position illustrated in Figs. 2 and 4 by engaging the upper teeth of theracks 28, and the lower sash now being freed from the upper sash and the upper sash being stationary, said lower sash may be lowered until the lower. edge thereof rests against the window stool 23, as illustrated in Fig. 2.

It will be seen that when the sashes are raised into theinclined position illustrated in Fig. 2 in the sash chamber 38, there is no danger of the same dropping accidentally, as they are firmly fixed in position by reason of the lower edge of the sash 18 resting in the holder 48, and also by reason of the sash balance 40 and chain 41 connected thereto and acting to hold them in their raised position.

If it is desired to lower the upper sash 17 for ventilation, independently of the lower sash 18, the spring bolts 26 are moved backwardly and said sash allowed to drop to the desired height when the bolts are released and spring into-engagement with the racks 28. Ifit is desired to raise the lower sash 18 independently of the upper sash 17, the spring bolts 24 are moved backwardly out of their respective recesses 25 and said window moved upwardly until said spring bolts are in a position in alinement with other recesses 25, when said spring bolts are released and snap into said recesses, allowing the lower sash to be partly raised.

It will be noted, by reference to Fig. 7, that the post 15 is formed of a single straight piece of lumberextending from the top to the bottom thereof, the inner face of said post15 lying in a vertical plane substantially from the bottom to the height of the top of'the upper sash, when said upper sash is in the position illustrated in Fig. 2, and the upper end of said post is widened in order to form a support for the inner inclined wall of the chamber 38 by adding thereto a wooden bracket or extension piece 15 The advantages of this construction are that, as hereinbefore stated, the inner wall of the chamber is at such, a height above the head of the person seated in the car that if said person stands up, his head or hat will not collide with said inner wall of the chamber 38, and moreover, the construction adds greatly to simplicity and economy, as the same requires Very much less lumber and labor to produce it, than would be required if the inner face of the post could not be formed upon a straight line or in the vertical plane aforesaid. This construction is rendered possible by the small area and depth of the chamber 38 and by the fact that the upper and lower sashes are cut out upon their lower outer edges and in their lower corners, respectively, so that the sashes can be ralsed and tipped into their inclined posltion in the chamber without widening the postloelow the top of the upper sash when said upper sash is in the position illustrated in Fig. 2.
