Application led .Tune i3, 1921.

To @ZZ cl2/om t may concern.'

Be it known thatl l, Gnoiicn d'. GODIN, a citizen-of the United States, residing at Rochester, in the county of Stratford and State of VNew Hampshire, have invented certain new and useful Improvements in lli/heel Attachments for Sleighs or Sleds, of which the following is specification.

My invention relates particularly to childrens sleighs or sleds and has for its primary objectto provide a wheel attachment therefor whereby the same may be ouickl converted into a wheeled vehicle when passing over swept sidewalks or the like.

Another object of the invention is to provide a device of the above character which is inexpensive to manufacture, easy to install on any sleigh or sledv without modification of the latter, and easy to manipulate;

lllhile l have indicated that my invention is primarily for use on childrens sleighs or sleds, it is to be understood that it may also be applied to invalids rocking chairs and the like.

These and suoli other objects as may hereinafter appear are attained by the novel construction, combinationand arrangementy of parts to be hereinafter specifically described and claimed.

Reference will now be had to the acccompanying drawings forming a part of this specification, wherein:

Figure l is a side elevation of a sleigh showing' my wheel attachment applied thereto and the wheels in operative position.

Figure 2 is a bottom plan view of the construction shown in Figure l.

Patented dirne t3, i222.. serial No. 477,099.

drawing, similar parts are referred to by like reference characters.

Referring to the drawings, the reference character A represents the body of a childs sleigh and B therunners thereof.

Attached to the bottom of the sleigh body are four brackets l to which are pivotally connected at one end the links 2. The other ends of the links 2 are pivotally connected to the ends of the front and rear axles 3 and l upon which are journaled the wheels 5. Also secured to the bottom of the sleigh body along the longitudinal axis thereof are spacedv brackets G and 7 each having' a depending slotted arm.

Slidably mounted in the slots of the depending arms of the brackets G and 7 is a member S. Fixed to thc front end portion of the sliding-"member 8in rear of the depending arm of the bracket T .is a transverse member 9, and connected to the members 8 and 9 are the diagonal brace members l0. The members 8, 9 and l0 `form a rigid frame which is slidable longitudinally of the bottom of the sleigh body.

he ends of the member 9 are turned upwardly at right angles thereto and pivotally connected to these upturiied ends at one end are the links ll having their opposite ends pivotally engaged with the front axle Also pivotally connected at one end to the upstanding ends of the member 9 are the toggles l2 which have their opposite ends pivot ally engaged with the rear axle 4l. ,l-ach toggle l2 comprises links 13' and .tl pivotally jointed at l5. Links 1G are pivotally connected at one end to the depending arms of the rear pair of brackets l by the same pivot pins which connect the ends of the rear links 2 to these arms and the links 1G' oppositev are pivotally connected at their ends to the links 13 of the toggle l2 inten mediate the ends ofthe latter-links. A coil spring 1T is connected at one end to a lug 18 depending from the bracket 6 and at its other end to the front end portion of the sliding member 8.

Secured to the under-side of the sleigh body at the rear end thereof is the transversely extended elongated bracket 1.9 havingits ends 2O 'and 20 bent downwardly at right angles thereto andA also having an iiitermediate downwardly extending arm 2l'. Fixed' in the arms 2O and 20 and 21 isa pivot rod 22 and pivoted on the rod 22 be tween the arms 20 and 2l is a latch operating member 23 shown in detail. in Figure 7. The latch operating member comprises a narrow strip of metal having its ends bent at right angles thereto and perforated to receive the pivot rod 22. lntegral with one end of the stri p is a pedal member 2li.

A latch member 25 has one end projecting through a vertical slot in the depending arm of the bracket 6. A pin 2G extending through this end of the member holds the member against rearward movement while the shoulder 27 prevents forward movement thereof. The member 25 extends rearwardly from the depending arm of the bracket 6 and has its rear end pointed and extending through a perforation 2S in the latch operating member intermediate the ends of the latter. The latch member 25 is provided intermediate its ends with a depending shoulder 29 adapted to engage behind the rear end of the sliding member S to hold the wheels 5 in lowered position as to be hereinafter explained.

For operating the sliding member S to lower the wheels to operative position a pedal member 3() is provided pivoted upon the rod 22 between the depending arms 2() and 2l and connected by a link 3l to a lug 32 depending fromA the member 8. The pedal member 30 is bifurcated at one end and the arms 33 thereof are perforated at their ends to receive the pivot rod 22. A pin 34 extends between the arms 33 near the tread portion of the pedal memberl 30 and one end of the link 3l is pivoted upon this A brake rod 35 extends transversely of the rear of the sleigh in position to engage the peripheries of the rear wheels 5. The brake rod 35 has its end portion 36 bent at right angles thereto and pivoted in the dependingl arms of the rear pair of brackets l. An operating pedal 37 for the brake rod is pivoted upon the rod 22 between the depcndin arms 20 and. 21 of the bracket 19 and a link 38 connects the pedal Eli' with the brake rod 85. The pedal 3T has an edge 39 which engages the bracket 19 to hold the pedal raised and the brake rod out of engagement with the wheels and another edge Il() for cooperation with the bracket 19 to hold the pedal depressed and the brake in engagement with the wheels.

The operation of the device is as follows: The normal position of the wheels is shown in Figure 3 in which they are shown raised out of contact with the ground. When it is desired to lower the wheels to operative position the operator places his foot upon the pedal 29 and depresses the same causing the member 8 to slide forwardly in the depending slotted arms of the brackets (i and 7 and carry with it the rigidly connected :salaries member 9. The forward movement of the member 9 forces the links ll which are connected to the axle forwardly and causesl the axle 3 to move ilorwardly and downwardly due to the link connection 2 between the axle 3 and the depending arms of the front pair of brackets l. At the same time the forward movement of the member 9 also causes the links 13 of the toggles l2 to swing in an anti-clockwise direction about their pivotal connections with the link 1G, thus straightening the toggles .l2 and lowering the rear pair of wheels 5. vWhen the sliding member 8 has moved forwardly to aposition to bring its rear end in front of the depending shoulder' 29 of the latch member 25 said shoulder drops behind the rear end of the sliding member 8 and holds the latter in operative position. This position of the sliding member 8 and latch member 25 is shown in Figure 6. By reference to this figure it will be noted that the latch operating member 23 tends to rotate by gravity in an anti-clockwise direction so that when the sliding member 8 is moved forwardly by means of the foot pedal 30 the latch member 25 will automatically engage the sliding member 8. ll/hen it is desired to move the wheels to inoperative or raised position the operator will place his foot in such position as to engage both the pedal 24: of the latch operating memberI 23 and the pedal 29. He will then depress the pedal 2Ll to raise the latch member 25 and release the sliding member 8. Then the sliding member S is thus released the tension of the spring 1T and the weight of the sleigh will cooperate to raise the wheels to inoperative position. ln order to prevent the jar resulting from the sudden raising of the wheels the operator will bear upon the pedal 29 with his foot permitting it to rise slowly, thus retarding the upward movement of the wheels.

lllhile l have described the members l2 as toggles, it will be noted that the links 2 and 'll which connect the front axle 3 to the front pair of brackets l and. to the upturned end of the member 9 are also in the nature of toggles, so that really both front and rear axles are suspended from the sleigh by toggles and the raising and lowering of the wheels is accomplished by a braking or straightening movement of these toggles.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:
