THORVALD HOLMES, OF LOSANGELES, CALIFORNIA, AND LAWRENCE HOLMES, OF CHICAGO, ILLINOIS.

EGG-BOILER.

SPECIFICATION forming part of Letters Patent No. 607,930, dated J uly 26, 1898. Application filed August 27, 1897. Serial No. 649,711. (No model.)

To all whom it may concern:

Be it known that we, THORVALD HOLMES, residing at Los Angeles, in the county of Los Angeles and State of California, and LAW- RENCE HOLMES, residing at Chicago, in the county of Cook and State of Illinois,'citizens of the United States of America, have in vented certain new and useful Improvements in Egg-l3oilers, of which the following is a specification.

Our invention relates to certain improvements in egg boilers, the purpose ofiwhich is to devise a boiler to automaticallyremove the eggs from the boiling water at the expiration of a predetermined period, thereby relieving the cook from the necessity of giving further attention thereto after placing theeggs in the water.

To such end our invention consists in certain essential features of novelty embodied in an apparatus which is made the subject of the following description, said essential features being pointed out in the claims at the end thereof.

For the purpose of illustrating our invention three sheets of drawings are herewith presented, containing ten figures, of which Figure 1 is a front elevation of a complete apparatus. Fig. 2 is a vertical section in line 2 2 of Fig. 7, looking in the direction of the arrow 2. Fig. 3 is a vertical section of the upper portion of the apparatus in line 3 3 of Fig. 7, looking in the direction of the arrow 3. Fig. 4 is a vertical section of the upper portion of the apparatus in line 4 4 of Fig. 7, looking in the direction of the arrow 4. Fig. 5 is a perspective of a portion of the apparatus, showing one of the cross-rods which bears a tripping device and a detent, the function of which will be set forth hereinafter. Fig. 6 is a perspective looking from the rear, showing the handle by means of which the appa ratus is set. Fig. 7 is a top plan of the apparatus with the cover broken away to show the interior of the clockwork. Fig. 8 is a vertical section of the upper portion of the apparatus in line 8 8 of Fig. 7, lookingin the direction of the arrow 8. Fig. 9 is a view similar to Fig. 3, showing a portion of the parts seen in the latter figure in a different position; and Fig. 10 is an enlarged view of certain parts shown in Fig. 2, made for the purpose of more clearly illustrating the construction and arrangement of said parts.

Looking at the drawings, an open framework A is seen, consisting of a base a, posts a, and a top a In this framework is guided a basket B, which is shown as open at the forward portion Z) and which is intended to contain and support eggs while cooking and to raise'the same from the boiling water at the end of a predetermined time. The basket has a bailb, to which is attached a chain 0, by means of which said basket is supported and raised. This chain extends upward through the top a of the frame and extends around and is secured to a drum D, (see Figs. 2, 7, and 10,) said drum being journaled upon a shaft E. Upon the top a of the frame is seen a box or cover F, within which and also supported upon said topare two side plates ff, between which are the works of a time mechanism journaled in and carried by said side plates. stated, has the drum D journaled upon it, is itself journaled in the side plates ff and extends forward through the front of the box F, where it carries a handle G, the use of which will be described hereinafter.

Within the drum D isa clock-spring H, secured at its inner end to the shaft E and at its outer end to the drum D, (see Fig. 10,) so that when said spring is placed under tension it tends to rotate the shaft in one direction and the drum in the other direction and may move both-together or one at a time. Upon the rear side of the drum is a large gear I, which is seen back of the spring H in Figs. 2 and 7 and which is also seen in Fig. 4 through the opening in the rear of the box. This gear is a portion of a train of gears 1 2 3 4, (see Figs. 2, 3, 4, and 7,) arranged to gain speed or velocity and terminatingin a spindle 5, carrying a fan 16 to limit the speed of the gears. This fan may of course be of any desired size and the preferred limit be thereby placed upon the speed of the drum D. In front of the drum is a large gear J, (see Fig. 3,) journaled upon the shaft E and forming apart of a train of gears 6 7 8 9 1O 11 12 13,

The shaft E, which, as before (see Figs. 3 and 7,) which terminates in a second spindle 14, (see Figs. 3 and 4,) carrying a second fan 15 to limit the speed of this train of gears. A ratchet-wheel K, fast upon the shaft E, and a spring-detent L, pivoted upon the gear J, furnish a means of engagement between the shaft and the gear in the direction in which the spring tends to revolve the shaft, but not in the opposite direction, in the same manner as is common in the works of an ordinary clock, so that the spring may be wound up by turning the shaft E without moving the train of gears 6 to 13.

Upon the front of the cover (see Fig. 1) is a dial M, containing a series of marks and appropriate figures, preferably so spaced and arranged in relation to the train of gears 6 to 13 as to represent minutes and fractions thereof. A stop on upon the dial is arranged to engage with a lug 9 upon the rear side of the handle G. (See Fig. 6.) The spring H tends to raise the point of the handle from the position seen in Fig. 1, and the stop on checks this movement when the handle is in an upright position,pointing to the mark numbered 0. Upon the front side of the handle are shown two lugs g g by means of which said handle may be conveniently turned by the hand. A pointer G is pivoted upon the shaft E and held against rotation thereon by friction with the dial. Said pointer has a forwardly-projecting lug g engaging with the handle, as is seen in Fig. 7, so that when said handle is set in any position .the pointer is necessarily also set at the same point and, being held by friction, remains at such point to show the original position of the handle after the latter has started on its return movement.

Extending across above the gears I J and journaled in the side plates ff is a shaft N, the position of which is shown from opposite sides in 'Figs. 3 and 4, the shaft itself, with its attachments, being shown in perspective in Fig. 5. Said shaft has a rigid arm n, which in its normal position rests upon a cross-rod 0 (see Fig. 3) and is held there by means of a spring a, coiled about the shaft and having one of its ends in engagement with the arm n and the other resting beneath the crossrod 0, as seen in Fig. 3. A second arm 02 extends back of the gear I, as seen in Fig. 4, and engages a lug'i upon said gear in the proper direction to prevent the rotation of the gear by the spring H, but is so arranged as to slide freely over the lug in the opposite direction. A third arm 02 upon the shaft N extends downward from the shaft and is formed into a loop 12 through which extends a loose arm a pivoted at its upper end upon the shaft and broadened at its lower end to engage a pin 6, (see Fig. 9,) rigid in the shaft E. Figs. 3 and 9 show the two extreme positions of the shaft N, the one shown in Fig. 3 being the normal position, in which the arm n rests upon the cross-rod O, and the position shown in Fig. 9 being that into which the shaft is forced by the engagement of the pin 9. It should be noticed that in the latter position the pin 0 is just ready to slip off of the point of the arm n and that the arm n is raised out of engagement with the lug 2', which is shown in dotted lines in Fig. 9. It should also be noticed from Fig. 3 that the arm n is held in position for engagement with the pin e by means of a spring or, coiled about the shaft and resting upon the cross-rod O. Said spring may yield, however, to allow the arm to swing to the right in Fig. 3 and permit the pin 6 to pass it in that direction.

WVhen the apparatus is not in use, the basket B is at the top of the frame A, the drum D pulls upward upon the chain 0 because of its engagement with one end of the spring, and the shaft-E holds the handle against the stop m because of its engagement with the other end of the spring. In operation the desired number of eggs are placed in the basket and the same drawn down within the frame to the extreme limit of its movement, which brings the lug 2' into engagement with the arm n holding the drum against the tension of the spring until this lug is released. The handle is then turned toward the right a distance corresponding to the length of time the eggs are to be boiled. This winds up the spring at the inner end correspondingly, and said spring has already been wound up at the outer end by the lowering of the basket. The turning of the handle advances the pin e past the arm W. The lower portion of the apparatus is placed in boiling water contained in a suitable vessel and the handle released. The tension of the spring immediately starts the train of gears 6 to 13,terminating in the fan 15. Said fan acts as an escapement controlling and regulating the movement of said train of gears in the same manner as is done in a watch or clock by means of a balancewheel or pendulum, and the fan is so proportioned that the handle G will reach its original position at the time the eggs are cooked to the desired degree. Just as such position is reached the arm (2 engages the arm of, oscillates the shaft E, raises the arm n releases the lug z', and allows the spring to rotate the drum, winding up the chain and raising the basket out of the water.

The pointer G is of use to indicate the time during which the last cooking was continued, and in case of a mistake it may often enable the same to be rectified before the eggs are taken from the water.

We recognize the possibility of great variation in the construction and arrangement of our apparatus, and therefore desire not to limit ourselves thereto; but

WVe claim as new and desire to secure by Letters Patent- 1. In a device of the class described the combination with a suitable frame and movable receptacle, of raising mechanism adapted to lift said receptacle out of the water, a time mechanism, a spring secured at one end to the raising mechanism and at the other end to the time mechanism, a stop adapted to hold the raising mechanism in check and means operated by the time mechanism at a predetermined time to release said stop and permit the raising mechanism to lift the receptacle from the water; substantially as described.
