7 FULLER DIE-VICE Filed Sept. 14, 1935 llauz'sIiDamm Patented Apr. 3, 1934 This invention relates to a puller device designed primarily for pulling sleeves of the cylinders of tractors, but it is to be understood that the device is adapted for use in any connection for which it may be found applicable, and the invention has for its object to provide, in a manner as hereinafter set forth, a hinged automatically adjustable device of the class referred to so constructed as to enable its employment for pulling sleeves of various diameter thereby overcoming the necessity of using independent pullers for sleeves of different diameters, and further whereby one puller in accordance with this invention may be employed for pulling the sleeves of a trac- '15. tor when such sleeves are of different diameters.

Further objects of the invention are to provide, in a manner as hereinafter set forth, a puller device for the purpose referred to, which is simple in its construction and arrangement, strong, durlg'0;able, compact, automatically adjustable, readily assembled, thoroughly eificient in its use, and comparatively inexpensive to manufacture.

To the above ends essentially and to others which may hereinafter appear, the invention con- 25.' sists of such parts, and such combination of parts which fall within the scope of the invention as claimed.

In the drawing:

Figure 1 is a fragmentary view in vertical sec- I tion of a tractor showing the adaptation with the sleeve of a cylinder thereof of the sleeve puller device, the latter being shown in elevation.

Figure 2 is an elevation of the coupling element of the device and showing the adjusted and nor- 3'51 mal positions of said element in full and dotted lines respectively.

Figure 3 is an elevation of the pulling element of the device.

Figure 4 is an edge view of the coupling element. Referring to the drawing, 1 denotes the body of a cylinder block in which is arranged the cylinder 2, the latter being provided with a sleeve 3 having a depending lower portion 4 providing a freed inner edge 5. The head for the body 1 of the block is not shown. The head, not shown, is constructed for the passage of spaced tie members 6 in the form of rods extended upwardly from the top of the body 1. The lower end marginal portion of the inner face of sleeve 3 is beveled as at '7. The inner end portion of sleeve 3 is reduced to provide a shoulder 7'. The foregoing is of known construction, and is illustrated for the purpose of showing the adaptation of the puller device with respect to the sleeve 3.

The puller device, in accordance with this invention, consists of a sleeve coupling element 8, a pulling element 9, an abutment element 11 and a shifting element 10 for the pulling element 9.

The element 8 comprises a body of inverted V-forrn constructed of any suitable metallic material of the desired length, width and thickness. The body of element 8 consists of three sections indicated at ll, 12 and 13. The section 11 includes an outwardly directed inclined side part 14,

a top part 15 of arcuate contour and an outwardly directed inclined side part 16 of less length than part 14. The

parts

14 and 16 merge at their inner ends into the ends of part 15, are disposed at an outward inclination with respect to the latter and incline in opposite directions with respect to each other. The part 16 is rabbeted on front and rear faces thereof to form said part with a reduced end portion 17 and on its front and rear face transversely thereof with a straight inner shoulder 18 merging into an inclined outer I5, shoulder 19. The outer corner at the free end of the reduced portion 17 is cut off to form an inclined edge portion 20. The free or outer end portion of the side part 14 at its outer side edge is grooved at 21 to provide a pocket and a jaw 22. 80, The groove is spaced adjacent the outer or free end edge 23 of side part 14. The section 12 consists of an outwardly directed inclined body part 24 having its inner end portion bifurcated to provide a furcation 25 and a pair of

arms

25, 26. Each arm has its end edge formed with a straight portion 28 and an inclined portion 29 which oppose respectively the inner shoulder 18 and outer shoulder 19. The inclined portions 28 are oppositely disposed with respect to the outer shoulder 19. The reduced end portion 17 of section 11 is arranged within the furcation 25. The outer end portion 30 of the side part 24 at its outer side edge is grooved, as at 31 to provide a pocket and a jaw 32. The jaw 32 is spaced adjacent the outer end edge 33 of side part 24. The section 13 is in the form of a rivet 34 having each end upset to form a head 35. The reduced end portion 17 and arms 25', 26 are formed with registering openings 36,

37 and 38 respectively through which extend the rivet 34 and the latter, in connection with the head 35 provide a permanent hinge connection between side part 16 and body part 24. The inner end edge of body part 24 is spaced from the body of side part 16. The outer end of side part 16 is spaced from the body of body part 24. The construction referred to provides a coupling element 8 of inverted V-form having one of its sides including a pivoted portion to provide for the adjustability of such element whereby it may be 1-10 so i employed for pulling sleeves of different diameters. When element 8 is in active position, it is arranged within and extends from the inner end of sleeve 3, and with the inner edge of the latter seated within the pockets provided by the

grooves

21, 31. The

jaws

22, 32 bearing against the outer face of the reduced inner portion of sleeve 3.

The pulling element 9 consists of a bar 36' of the desired length and diameter formed at one end with an eye 37'. The bar 36 is provided with peripheral threads 38.

The abutment element 11 is in the form of a flat plate 39 for seating on the tie members or rods 6 and is provided with an opening 40 positioned in alignment with the axis of sleeve 3.

The shifting element 10 coacts with the abutment element 11 for shifting the pulling element 9 and is in the form of a nut 41.

The eye 37' of element 9 is for the passage of the top of the coupling element 8. The opening 40 in element 11 is for the passage of bar 36'. The nut 41 is for engagement with the threaded portion 38 of element 9 and for bearing against the upper face of plate 39. Now when the coupling element 8 is positioned relatively to sleeve 3 in the manner as shown in Figure l, and the other parts of the device arranged as shown in Figure 1, on revolving of element 10 in a clockwise direction, the element 9 will be shifted outwardly whereby element 8 will act to pull the sleeve 3 the necessary distance to enable the sleeve to be acted upon by any suitable means to cause the complete Withdrawal thereof.

What I claim is:-

In a sleeve puller device, a body of inverted V- form consisting of an arcuate top part merging at its ends into the upper ends of a pair of oppositely disposed outwardly inclined side parts, one of greater length than the other, said side part of shortest length having the major portion of its length of reduced thickness with respect to and arranged outwardly of and merging into the lower end of the remaining portion of said short side part to provide the latter with a pair of spaced parallel edges, each consisting of a straight inner portion and an upwardly inclined outer portion, the said portion of reduced thickness having its lower end edge of a contour corresponding to said edges, a movable side part forming an outwardly inclined lengthwise continuation of the said side part of shortest length and having its upper portion bifurcated for overlapping the said portion of reduced thickness, means for pivotally connecting said bifurcated portion intermediate its ends to said portion of reduced thickness, said bifurcated portion having its pair of spaced parallel upper end edges formed with straight inner portions opposing the said other straight portions and a pair of outer portions inclining away from said other inclined portions, and said side part of greatest length and said movable side part being formed in proximity to their lower ends and at their outer sides with pockets and tongues of square cross section and with each tongue forming the outer wall of a pocket.
