GREASE-RECEPTACLE CARRIER AND JACK.

Application filed April 11, 1922.

To all 10 7mm it may concern:

Be it known that we, AUSTIN O. SARFF and FLorn D. DENNEY, citizens of the United States, residing at Walker, in the county of Cass and State of Minnesota, have invented certain new and useful Improvements in Grease-Receptacle Carriers and Jacks, of which the following is a specification,

This invention relatesto new and useful improvements in means for facilitating the handling of heavy objects and is especially designed for conveniently handling large receptacles used in bakeries and analogous trades, to obviate the many serious accidents occuring to persons handling such receptacles which usually carry from fifty to one hundred pounds of red hot burdensome load for even two men to handle with safety.

Another object of my invention resides in the provision of a device of the above nature including means whereby a receptacle of the above named character may be 1 handled in such a manner that one person may easily transport the receptacle from place to place, raise and lowerthe receptacle from and to a support or furnace, and can readily tilt the receptacleon the device for emptying material therefrom.

A further object of the invention is to construct the devicein such a manner that it can be readily adapted for use in con- ,junction with receptacles and furnaces of changing the arrangement of any of the parts thereof. l

A still further object of-the invention 15 character including means by which a receptacle or object can be either rigidly retained in its ordinary horizontal position, or pivoted loosely so that the same may be tilted for emptyingthe same.

Another object of 'theinvention is to provide a device which is durable in. its construction, eflicient in practice and one which can be manufactured at a minimum cost.

Other objects and advantages of the incourse of the followingdescription.

In the accompanying drawings forming a part of the description and wherein like numerals are employed to designate like parts throughout the several views,

ture of the invention.

ven-tion will become apparent during the Serial No. 551,737.

Figure 1 is a side elevation of the device,

Figure 2 is a horizontal section through a portion of the same,

Figure 3 is a detail perspective View of a part of the invention, and

F gure 4 is a similar view of another fea- In the drawing, wherein for the purpose of illustration is shown the embodiment of our invention which is at present preferred, the numeral 5 designates the base of the device in general and which consists of a pair of horizontal spaced parallel side bars 6, to the forward end of each is secured a laterally extending axle for a wheel or roller 7.

An upright member 8 is secured to each side bar 6 and consists ofa single length of strap material bent into inverted U- shaped form to provide a pair of vertical spaced parallel legs 9, the lo-werfree ends of which are secured in spaced relation to its respectiveside bar 6. The intermediate or bridging portion 10 of the "member 8 is arranged in a horizontal plane as shown, and the broad flat surface of the bridging portion is arranged in a plane at right angles to the plane of the broad flat surfaces of the legs 9 by reason of the fact that the material from which the member 8 is formed is bent or twisted as at 11. The

bridging portion 10 of each member 8 is provided with a central aperture 12 for a purpose which will be presently described.

The two upright members 8 are supported in spaced uprigl'it'relation by a pair of arched or U-shaped metallic straps 13, each of which has one end secured to the upright 8 at one side of the device, while the opposite end is connected to the upright on the other side of the device; It will be noted that these straps 13 are arranged in spaced relation to each other, and that one is connected to the uprights 8 adjacent their upper ends, while the other is fastened to the members 8 adjacent their lower ends. These straps are, of course, arranged horizontally as shown and are preferablv of such dimensions as to engage a vertical wall of a furnace 14 of the type ordinarily used in bakeries for frying doughnuts and cooking other material, whereby the tip- A handle for the device, which is pref-- erably U-shaped in configuration, has its free ends secured to the relative inner faces of the legs 9 of the uprights to which the straps 13 are fastened. This handle is secured to the approximate intermediate portions of their respective legs 9 and the handle is maintained in an inclined position as shown by means of supports 16 which have their upper ends secured to the arms of the handle, and their, lower ends fastened to the inner endsof the side bars 6. However, it is to be noted, that the lower ends of the braces 16 extend slightly below the side bars 6 to form legs 17 for supporting the bars. 6 in perfect horizontal position.

A vertically sliding bar 18 is extended througlreach opening 12 in the bridging portions of the uprights 8, and the lower end of each movable bar is equipped with a longitudinally arranged series of spaced apertures 19 and one of which is adapted for the reception of a bolt 20 carried by the free upwardly curved ends 21 of a preferably U-shaped lever and handle 22.

Each arm of this lever is fulcrumed adjacent its arcuate forward end 21 to the outer surface of its leg 9 of the upright as at 28. The same bolts which are used for connecting the free ends of the handle 15 to the uprights, are employed for fulcruming the free ends of the lever 22 as shown. The lever is of substantially the same size and shape as the handle 15, and being con.

- nected to the outer faces of the legs 9 of the uprights, while the arms of the handle 15 are connected to the inner faces of the ends of the said arms, it will be seen that the levercan be swung to be arranged just outside of the handle 15 and in the same plane therewith so that both the handle 15 and lever 22 can be used as a handle for moving the device as will be more clearly set forth presently.

The upper ends of the vertically movable bars 18 are extended above the bridging portions 10 of the uprights and are there provided with an opening 24k for the reception of threaded studs 25 extending laterally from attaching plates 26 secured to opposite sides of a receptacle 27 at diametrically opposite points thereon. The form of receptacle 27 herein illustrated is of a shape corresponding to that of grease receptacles usually employed in bakeries for cooking doughnuts and the like, but it will of course, be understood that any form of receptacle may be handled equally as well with the device. A wing nut 28 provided for each threaded stud 25 and is adapted to be screwed thereon. after the stud has been projected through the openings in the upper ends of the bars 18 for preventing accidental displacement of the receptacle.

. One of the attaching plates 26 fastened,

to one side of the receptacle is provided with a recess 29 at the intermediate portion of its outer face for the reception therein of a portion of the upper end of one of the bars 18 so that the receptacle 27 can be prevented from tilting movement on the bars 18 when the wing nuts 28 have been threaded upon the studs. The attaching plate at the other side of the receptacle is not provided with such a recess so that by simply loosening the wing nut associated with the grooved attaching plate 26, the receptacle can be tilted as desired, and conversely by tightening the wing nut associated with the grooved attaching plate 26, one bar 18 can be forced into the recess 29 to engage the opposed shoulders thereof for preventing accidental tilting movement of the receptacle 27.

As stated in the objects ofthe invention, the device is primarily adapted forhandling receptacles containing hot material such as grease used, for frying doughnuts in bakeries, but it is to be understood that we do not limit the use of the invention to this one particular trade or use, as it is simply mentioned to demonstrate the extreme usefulness of the device in one particular field. However, assuming that it is desired to remove the receptacle 27 full of hot grease from the furnace 14, the carrier and jack is grasped by the handle 15 and rolled up to the furnace to straddle the sides thereof, so that the straps 13 will engage one side orthe front of the furnace to dispose the vertically movable bars 18 at diametrically opposite points at the sides of the furnace.

The receptacle is then turned on the stove so that its threaded studs 25 can be passed through the apertures 24 in the bars 18 when the lever 22 has been slightly depressed to effect such alinement. After threading the wing nuts 28 on the studs, it will be appreciated that the upper ends of the bars 18 will be forced into binding engagement with the attaching plate 26 and one of the bars will be forced into the recess 29 of the attaching plate so that the receptacle cannot pivot when removed from the furnace, by the device. i Afterv this attachment has been effected and the proper adjustment is had between the lever and the vertically movable bars 18,,

the lever 22 is depressed until its arched portion can be grasped along with the handle 15. cause its forward free ends to move vertically and impart corresponding movement to the bars 18 so'that the receptacle 27 will be elevated from the top of the stove whereby the handle 15 and lever 22 may be grasped and pulled rea'rwardly so that the device is rolled away from the furnace with little difliculty. The device with the receptacle can then be rolled to any point to transfer Such movement of the lever will the receptacle to a table or any other support, or if it is desired to empty the grease from the receptacle; which is often done for changing or clarifying the grease, the lever 22 can be released so as to permit the receptacle to lower until it rests upon the bridging portion 10 of the uprights 8. The wing nut 28 associated with the attaching plate having the recess 29 therein is then loosened suiliciently to permit pivotal movement of the receptacle, after which the lever 22 is depressed to elevate the receptacle sufficiently to permit the same to pivot and empty the contents.

A laterally projecting handle 30 may be fastened to one side of the receptacle at a point equi-distant from the two attaching plates 26 to facilitate tilting movement of the receptacle. When the device is rolled up to the furnace with the receptacle and the uprights 8 straddle the furnace, it will be seen that the lever 28, can be released so that it will permit the receptacle to lower and rest upon the furnace. The wing nuts 28 are then removed from the studs so as to permit removal of the upper ends of the bars 18 from the studs, after which the bars can be readily lowered and one of them slides out of its recess 29 and is free from the receptacle so that the device may be rolled away from the furnace.

The foregoing description and the accompanying drawings have reference to the preferred or approved embodiment of our invention. It is to be understood however, that such changes may be'made in construction and arrangement of parts, materials, dimensions, etc., as may prove expedient and fall within the scope of the appended claims.
