Application May 15, 1942, Serial No. 443,131

2 Claims.

This invention relates to new and useful improvements in valve removers for internal combustion engines.

The principal object of the present invention is to provide a device whereby all the valve springs of an engine can be held simultaneously to permit removal of the holding keys in quick succession.

Another important object of the invention is to provide a device of the character stated which can be readily applied and removed with respect to an internal combustion engine.

Other objects and advantages of the invention will become apparent to the reader of the following description.

In the drawings Figure 1 represents a plan view showing the valve remover applied to an engine head.

Figure 2 is a side elevational view of the apparatus in use on an engine head.

Figure 3 is a side elevational view looking at the opposite side from that shown in Figure 2, showing the apparatus applied to an engine 1 head.

Figure 4 is a fragmentary detailed sectional view taken substantially on the line 4-4 of Figure 1.

Figure 5 is a perspective view of one of the spring holding sleeves.

Figure 6 is a side elevational view showing the engine head inverted preparatory to removing the valves.

Figure 7 is an end elevational view of the structure as represented in Figure 6.

Figure 8 is a side elevational view of one of the stand bolts.

Referring to the drawings wherein like numerals designate like parts, it can be seen that numeral 5 denotes an engine head having valve seats 6 against which valves 1 are operated. These valves 1 have stems 8 on which are springs 9, these springs 9 being held in place by cups I0 abutting pins II extending through openings in the free end portions of the stems 8.

In carrying out the present invention, an elongated bar I2 is provided at certain spaced intervals with slots I3 through which the free end portions of the stems 8 with their key pins I I can protrude, as is suggested in Figure 2.

In addition the present invention includes a pair of L-shaped arms I4, I4, the foot portions a of which have threaded openings therein for receiving the threads of clamp screws I5, each of which has a crank handle I6 at one end and an engine head engageable member I! at its opposite end.

The remaining ends of the arms I4 have openings therein to permit these ends of the arms I4 to be slipped over the opposite ends of the bar l2 and secured in place by set screws I8.

Arranged on the bar I2 are spring holding sleeves I9 equivalent in number to the springs 9 to the particular engine head being handled. Each of these sleeves I9 has a pair of diametrically opposite legs 20 at one end thereof and each of these legs has an inturned lug 2I which overlaps the bar l2. These legs 20 and lugs 2| permit the sleeves I9 to-be slid to any desired adjusted positions on the bar I2. In other words, these sleeves I9 are adjusted on the bar I2 and the bar brought toward the head 5 so that the sleeves I9 are disposed over substantial portions of the springs 9.

The arms I 4 are then applied to the bar I2 and the clamp screws I5 operated inwardly so as to draw the bar I2 toward the top side of the engine head 5. It is, of course, understood that the engine head 5 is set on one side as suggested in the top plan view, Figure 1, so that the clamp screws [5 can be conveniently operated and so that when the bar I2 has been drawn in close enough to the top side of the engine head 5, the spring retaining pins I I can be easily removed as they will then be protruding beyond the outermost side of the bar I2.

When the pins I I have been removed and subsequently the springs 9, stand bolts 25 can be applied. Each of these bolts 25 has a threaded portion 1) and on each threaded portion b are nuts 26, 21. The threaded portions 1) of these bolts 25 can be disposed through the corner openings 28 of the engine head 5 and the bolts 26 driven against the opposite sides of the engine head. Thus, supporting legs are provided for the head 5 so that the head 5 can be supported in inverted position as shown in Figure 6, thus permitting easy removal of the valve elements and convenient positioning of the head for various operations thereon.

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

Having described the claimed as new is:

1. A spring remover for engine heads comprising an elongated bar formed with openings thereinvention, what is in for receiving the spring retaining pin ends of valve stems, a pair of arms each having an opening in one end thereof for receiving a corresponding end of the bar, and clamp means on the remaining ends of the arms for exerting force against the corresponding side of an engine head, and a plurality of sleeves on the bar for embracing valve springs, each of the sleeves being provided with means for slidably connecting the same to the bar.

2. A spring remover for engine heads comprising an elongated bar formed with openings therein for receiving the spring retaining pin ends of valve stems, a pair of arms each having an opening in one end thereof for receiving a corresponding end of the bar, and clamp means on the remaining ends of the arms for exerting force against the corresponding side of an engine head, and a plurality of valve spring embracing sleeves, each of said sleeves being provided with a pair of legs at one end and lugs on the legs for overlapping the bar to slidably connect the corresponding sleeve to the bar.
