DEVICE FOR REMOVING ARTICLES FROM sHArTs.

To all whom it may concern:

Be it known that I, GEORGE W. SCHILLING, a citizen of the United States, residing at in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Devices for Removing Articles from Shafts, of which the following is a specification.

One object of my invention is to provide a device of comparatively simple con struction which will efficiently operate to remove articles such as gearwheels, pulleys, collars, couplings or propellers from shafts.

Another object is to so construct my invention that it can be made comparatively small and durable and will be operative to loosen and remove articles such as above noted irrespective of their position on the shaft; that is to say it will remove an article which is close to the end of the shaft or remove an article which is within the length of the shaft and a comparatively great distance from the ends of the shaft. Thusby my invention it is possible for example to shift or loosen a gear wheel or pulley which is interposed between two other articles on the same shaft.

A still further object is to so construct my invention that it can be easily positioned and manipulated by one man and can also'be used for removing articles from shafts irrespectiveof whether the shaft is mounted in its hearings or detached therefrom. In this connection it will be noted that my invention can be mountedon a work bench or the like for removing articles from detached shafts.

These objects,

"ends which will be described hereinafter, I

attain in the following manner, reference being had to the accompanying drawings in which- I Figure 1 is a top plan view of my inven tion showing how it can be positioned to remove a three blade propeller from a shaft, said propeller being shown in dot-and-dash lines and near thefefnd' of the shaft, Fig 2 is a section-taken on the line 22 of Fig. l,

Application filed October 22, 1918. Serial No.259,245.

Fig. 5 is atop plan view of the link lever shown in Fig. 4,

Fig. 6 is a top-plan view of my invention showing the same secured to a shaft within its length and operative to loosen a gear wheel attached to said shaft, and Fig. 7 is a section taken on the line 7-7 of Fig. 6. j

' Referring to the drawings and particularly to Figs. 1 to 5inclusive, 9 represents the head of my improved device which is made in two

sections

10 and 11 joined together at 12 by bolts 13. This head has a central hole 14 which is screw threaded and part of the hole being formed in each of the

sections

10 and 11. This hole is adapted to receive a screw threaded plug 15 which has a centering pin 16 projecting outwardly from one end. 7

The head 9'is also provided with a projecting collar 17, substantially one half of the collar being carried by each of the

sections

10 and 11. This collar has set screws 18 arranged around its circumference, clearly shown in Figs. 1 and 3, and can be used if desired to secure the plug 15 within the head 9 or, as will hereinafter be explained, these set screws can be used for another purpoSe when the device is desired for use irn the capacity illustrated in Figs. 6 and i The head 9 has three

slots

19, 20, and 21 through which pass bolts 22. These bolts 22 are screw threaded at their opposite ends, said screw threading extending a considerable distance inwardly from said ends, as clearly illustrated in Fig. 1.

Offset link levers 2 3 are provided, each of said levers having a circular hole 24 adjacent one end and an elongated slot 25 adjacent the opposite end. Three of these levers are arranged to register or overlap each other, as

clearly shown in Figs. 1 and 2, the slots 25 1 shaft.

21 permitting adjustment radially of the bolts 22 to suit various requirements for different size shafts or for wheels, propellers or the like of different sizes.

Groups

26 and 27 of the link levers 23 are provided at opposite ends of the bolts 22, the group 27 engaging the surface 28 of. the head 9, while the group 26 as illustrated 18 in engagement with the blades of a propeller 29 and encircle the shaft 30 upon which the propeller is secured.

The center pin 16 is adapted to enter the centering recess 31 which is usually present in all shafts either for the purpose of taking count of the revolutions of the shaft or for the reason that the recess was formed when the shaft was being turned in the lathe.

Nuts

32 and 33 are provided on the opposite ends of the bolts 22 and by turning these bolts the group 26 of link levers 23 will move toward the head 9 and in so doing will slide the propeller 29 toward the adjacent end of the shaft 30. In this manner the propeller can be quickly and easily removed from the Each of the offset link levers 23 is provided with a recess 34 so that when the levers of these groups are in position such for example as shown in the group 26, they will encircle and provide room for the shaft to pass therethrough; this arrangement beingshown in assembly in Fig. 2.

If it is desired to remove or loosen an article located within the length of the shaft, for example between two other articles, the head 9'can be clamped directly to the shaft by removing the bolts 13 and separating the

sections

10 and 11. The head thus separated can be placed at the desired position on the shaft and after thus positioned the bolts'13 can again be inserted and tightened; it being of course noted that the plug 15 has previously been removed. The set screws 18 can then be used to secure the head to the shaft, as clearly shown in Fig. 7. The bolts 22 can then be inserted through the slots 19 and the levers 23 can be arranged

inthe groups

26 and 27. The'article to be removed, such for example as the gear wheel 35, being positioned between the group 26 of levers and the head 9 can, by turning the

nuts

32 and 33, be slid longitudinally of its shaft to free its key 36.

The head 9 is provided with feet 37 so that it can he stood upon a work bench and these feet 37 are provided with holes 88 so that if desired the head can be bolted to a bench or any other obj eet desired.

The offset formation of the link levers 23 provides a strong interlock so that the groups have their opposite faces substantially flush so as to evenlyengage the side surfaces of gear wheels, pulleys, propellers or the like and as clearly evident from the several views of drawing.

Furthermore, by having the head 9 provided with the set screws 18 it is an easy matter to quickly clamp the head to a shaft and the hands of the workman are free to manipulate the bolts 22, link levers 23 and

nuts

32 and 33.

While I have described my invention as taking a particular form, it will be understood that the various parts of my invention may be changed without departing from the spirit thereof, and hence I do not limit myself to the precise construction set forth, but consider that I am at liberty to make such changes and alterations as fairly come within the scope of the appended claims.

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

10. A device of the character described including a head adapted to be supported on a shaft, said head having slots therein eX- tending in a substantially radial direction; bolts extending through said slots; and a group of overlapping levers having register ing openings therein, certain of which are in the form of slots, said bolts respectively extending through said registering openings, said bolts having nuts thereon whereby when the nuts are tightened said levers are moved toward said head, said slots in the levers and head permitting adjustment of said bolts toward or from each other, substantially as described.

11. A device of the character described including a head adapted to be supported on a shaft, said head having slots therein extending in a substantially radial direction bolts extending through said slots; and groups of overlapping levers at opposite sides of said head, the levers of each of said groups having registering openings therein, the form of slots, said bolts respectively extending through said registering openings, said bolts having nuts thereon whereby when the nuts are tightened said levers are moved toward said head, said slots in the levers and head per mitting adjustment of said bolts toward or from each other, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
