MOVING IMPLEMENT.

Patented July 9, 1918.

Application filed August 23, 1915. Serial No. 46,932.

To all whom it mag/concern:

Be it known that I, HARRY WV. MOKEE, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Moving Implements, of which the following is a specification.

It is the object of my invention to'provide an implement arranged for engagement with a load, for instance a packing box, crate, or other object, for lifting the same, or for shifting the same upon the floor, de pending on the point of contact with the load and the direction in which the force of the moving member is applied.

I have exemplified my improved device as applied for lifting a box and also for lifting a crate, from which representations its application in other relations may be readily perceived.

My improved device is intended for lifting very heavy loads, and is compactly arranged, and so constructed as to enable great power to be applied, and for maintaining the members in moved relation for preventing accidental retraction of the same.

The invention will be further readily understood from the following description and claim, and from the drawing, in which latter:

Figure 1 is aside elevation of my improved device, shown applied for lifting a large packing case.

Fig. 2 is a side elevation of the same, showing the packing case in lifted relation with a moving roller thereunder, the moving bar being partly broken away.

Fig. 3 is a front elevation of my improved device with the socket for the movingbar partly broken away.

Fig. 4 is acentral vertical section of the same taken on the line 44: of Fig. 3.

Fig. 5 is a plan view of my improved device with the moving bar removed.

Fig. 6 is a cross-section of the same taken on a line corresponding to the line 6-6 of Fig. 4. j

Fig. 7 is a bottom perspective view of the lower portion of my improved device; and,

Fig. 8 is a side elevation of my improved device showing the same applied for moving a crate.

11 represents the housing of my improved device, in which a moving member, shown as a slide 12, is arranged to slide. The housing comprises a front wall 13, from ing member in the housing.

The housing is provided at its lower end with lateral extensions 17, the sides of the housing conforming to the shape of said extensions and strengthening the same. The housing also has a bottom wall 20 provided with a large number of projections 21 projecting downwardly from said bottom wall for forming a roughened surface which finds ready lodginen't on the floor or other surface against which said bottom wall is placed, holding said bottom wall in place without injury to the fioor or other object and preventing shifting of the housing.

The moving member has a rear wall 24 and is provided with side flanges 25 extending longitudinally thereof, and projecting forwardly in a direction opposite to the direction in which the sides 14: extend, for forming a longitudinal space 26 between the front wall of the housing and the rear wall of the slide. The rear edges of the side flanges of the slide are provided with rearwardly and inwardly projecting slanting faces 28 arranged to engage the forward faces of the rearwardly and inwardly projecting wings 15 for maintaining the mov- The front face of the rear Wall 24 of the slide is provided with a tooth-rack 29' extending longitudinally of said slide, the

teeth projecting forwardly and crosswise of the slide.

The upper end of the slide is provided with an upwardly and rearwardly curved upper end 31, provided with a plurality of teeth 32 arranged crosswise of the upper end of said slide, for engagement with the object to be moved, for instance, a packing case, illustrated at 33 in Figs. 1 and 2. These teeth are arranged to embed themselves in the wood of the case for forming a hold upon said case.

The moving member is further provided at its lower end with a rearwardly extending shelf 36 preferably formed with a brace 37 thereunder connecting with the moving member.

For moving the moving member the housing is provided with forwardly extending separated lugs 41 having a slot 42 between them. A segment-gear 43 is pivoted on a ment with the teeth of the rack- 29.. The.

segment-gear is provided with a socket extension H- n gr there in w ich. a

moving bar 48 is arranged to be seated, a pin 49 holding the bar in the socket.

The housing 11 is provided with a crossgirt 51 integral therewith for connecting the upper ends of the sides of the housing and insuring rigidity. The upper end of the housing'at said cross-.girtis provided with upwardly extending separated lugs 52, forming bearings for a pin 53, on which an upwardly and rearwardly extending pawl 54 is pivoted, the pawl being received in the channel between the sides flanges 25 of the slide 12' into engagement with the rack-teeth provided for the purpose of coaction with the segment-gear.

Referring to Figs. land 2, it will be noted that, when it is desired to lift an object, the housing and moving member are placed slantingly with relation to theside of'said object, and that the bottom of the housing is in a plane extending at an acute angle with relation to the longitudinal axis of the housing, so that when said housing andlifting member are slantingly placed, as

stated, the bottom of the housing will be parallel with the floor so as to have support on the floor over a comparatively large area, thereby preventing injury to the floor.

The depression of the, moving bar 4L8 causes raisingof the lifting member for raising the packing case, for the purpose, for instance, of inserting a roller, shown at 56, under said packing case. As the bar is lowered and the lifting member raised, the teeth 32 indent theobje ct to be moved, embedding themselves therein to get. a firm hold upon the object, and then raising the object. The pawl 54 engages successive teeth passing the pawl for preventing accidental retraction of the lifting member or slide.

If it is desired to release the device, a slight depression of the bar 48 will permit the release of the pawl, and for enabling ready release of the pawl to be had, I provide the same with a rearwardly and upwardly extending heel 57 upon which the foot may be placed for-retracting the pawl, whereupon raising of the bar 48 is ermitted for allowing the weight of the pac ring case to be received upon the roller and for releasing the device.

When it is desired to raise an object with which the teeth 46 would not be liable to make secure contact, the shelf 86 is received under a portion of the object to be raised,

as under the cross-piece 58 of a crate, the cross-piece for instance being upon skids 59 and in sufiiciently raised position for permitting insertion of the shelf 36 thereunder.

The direction of movement of the object to be moved will be longitudinal with relation to the sliding movement" of the slide,

so that the direction of movement of the object will be determined by the manner in which the housing and moving member are placed between the object to be moved and an immovable partL a My improved device is heavily constructed and is arranged to be formed of cast steel. It is of great strength and compactly arranged and of few parts.

The front wall and bottom wall of the housing are provided with a recess 61, in which a crow-bar, spike, or other positionretaining device may be received when desired, this recess being in linewith the longitudinal axis of the device.

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

t A moving implement comprising a housing having a front wall and rearwardly extending side-walls terminating in rearwardly and inwardly slanting wings proj'ecting toward each other for forming a slide-guide space extending longitudinally in the housing, a slide provided with a rear wall and forwardly projecting flanges and having a web between said flanges spanning the space between said wings, said slide having rear rearwardly and inwardly projecting faces projecting toward each other and coacting with said wings, said forwardly projecting flanges on said slide and said side walls of said housing arranged for forming a space extending longitudinally between said housing andslide, a'tooth-rack on said slide in said space and spaced from said front wall, the front wall of said hous ingprovided witha'slot, a segmentgear pivoted to said housing and extending through said slot and into said longitudinallyextending space into engagement with the teeth of said rack, apawlpivoted to said housing and extending into said'space into engagement with the teeth of said rack,'and a moving bar for moving said slide extending from said segment-gean v c In testimony whereof, I have hereunto signed my name in the presence of two subscribing witnesses.
